[Docket No. NHTSA-2013-0137]
Visual-Manual NHTSA Driver Distraction Guidelines for Portable
and Aftermarket Devices
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation (DOT).
ACTION: Notice of proposed Federal guidelines.
-----------------------------------------------------------------------
SUMMARY: This notice details the proposed contents of the second phase
of the National Highway Traffic Safety Administration's (NHTSA) Driver
Distraction Guidelines (Phase 2 Guidelines). The purpose of the Phase 2
Guidelines is to provide a safety framework for developers of portable
and aftermarket electronic devices to use when developing visual-manual
user interfaces for their systems. The Guidelines encourage innovative
solutions such as pairing and Driver Mode that, when implemented, will
reduce the potential for unsafe driver distraction by limiting the time
a driver's eyes are off the road, while at the same time preserving the
full functionality of these devices when they are not used while
driving. Currently no safety guidelines exist for portable device
technologies when they are used during a driving task. NHTSA seeks
comments and suggestions to improve this proposal.

I. Executive Summary
A. The Driver Distraction Safety Problem
In 2015,\1\ 10 percent of the 35,092 traffic fatalities involved
one or more distracted drivers, and these distraction-affected crashes
resulted in 3,477 fatalities, an 8.8 percent increase from the 3,197
fatalities in 2014.\2\ Of the 5.6 million non-fatal, police-reported
crashes in 2014 (the most recent year for which detailed distraction-
affected crash data is available), 16 percent were distraction-affected
crashes, and resulted in 424,000 people injured.

(last accessed on 10/4/16). 2014 data are the most recent data
available.
---------------------------------------------------------------------------
The crash data indicate that visual-manual interaction (an action
that requires a user to look away from the roadway and manipulate a
button or interface) with portable devices, particularly cell phones,
is often the main distraction for drivers involved in crashes. In 2014,
there were 385 fatal crashes that involved the use \3\ of a cell phone,
resulting in 404 fatalities. These crashes represent 13 percent of the
distraction-affected fatal crashes or 1.3 percent of all fatal
crashes.\4\ The data also indicate that there were a number of fatal
crashes that involved the use of a device or object brought into the
vehicle (some of which may also have been crashes that involved the use
of a cell phone). This catch-all category includes crashes that
involved the use of portable devices, such as navigation devices, in
addition to other types of objects (e.g., cigarette lighters). Of the
967,000 distraction-affected crashes in 2014, 7 percent (or 1.1 percent
of all crashes) involved the use of cell phones and resulted in 33,000
people injured.\5\
---------------------------------------------------------------------------
\3\ Use of a cell phone includes talking on or listening to a
cell phone, dialing or texting on a cell phone, and other cell-
phone-related activities.
\4\ Other types of distraction-affected crashes include those
caused by daydreaming, eating or drinking, smoking, and conversing
with a passenger. See NHTSA. (2016). Traffic Safety Facts Research

B. What is driver distraction?
Driver distraction is a specific type of inattention that occurs
when drivers divert their attention away from the driving task to focus
on another activity. This distraction can come from electronic devices,
such as texting or emailing on cell phones or smartphones, and more
traditional activities such as interacting with passengers, eating, or
events external to the vehicle. Driver distraction can affect drivers
in different ways, and can be broadly categorized into the following
types:
Visual distraction: Tasks that require the driver to look
away from the roadway to visually obtain information;
Manual distraction: Tasks that require the driver to take
one or both hands off the steering wheel to manipulate a control,
device, or other non-driving-related item;
Cognitive distraction: Tasks that require the driver to
avert their mental attention away from the driving task.
Tasks can involve one, two, or all three of these distraction
types.
NHTSA is aware of the effect that these types of distraction can
have on driving safety, particularly visual-manual distraction. At any
given time, an estimated 542,073 drivers are using hand-held cell
phones while driving.\6\
[[Page 87658]]
Moreover, when sending or receiving a text message with a hand-held
phone, the total time that a driver's eyes are focused off the road is
23 seconds on average.\7\ This means while traveling at 55 mph, a
driver's eyes are off the road for more than a third of a mile for
every text message sent or received.

C. NHTSA's Efforts To Reduce Driver Distraction
As an agency committed to reducing deaths, injuries, and economic
losses resulting from motor vehicle crashes, NHTSA has initiated, and
continues to work toward eliminating crashes attributable to driver
distraction. Most prominently, NHTSA and the United States Department
of Transportation (US DOT) have encouraged efforts by states and other
local authorities to pass laws prohibiting hand-held use of portable
devices while driving. NHTSA, in conjunction with industry, local
governments, and various public interest groups, has also taken
numerous steps to educate the public about the dangers of distracted
driving.
However, until distracted driving is eliminated, the agency must
work in the real-world where many drivers continue to use their
portable devices and other in-vehicle systems in unsafe ways while
driving. Thus, NHTSA has also worked on how to mitigate the distraction
that may be caused by these new technologies. In April 2010, NHTSA
called for the development of voluntary guidelines addressing driver
distraction caused by in-vehicle systems and portable devices.\8\ This
sentiment was reinforced by the US DOT's and NHTSA's June 2012
``Blueprint for Ending Distracted Driving.'' \9\ The blueprint is a
comprehensive approach to the distraction problem. The three steps
outlined in the blueprint include: Enacting and enforcing tough state
laws on distracted driving, addressing technology, and better educating
young drivers. All three components are necessary to address the
distraction issue. The Distraction Guidelines focus on step two by
addressing technology.

---------------------------------------------------------------------------
The development of non-binding, voluntary guidelines for in-vehicle
and portable devices is being implemented in three phases. The Phase 1
Driver Distraction Guidelines (Phase 1 Guidelines), released in 2013,
cover visual-manual interfaces of electronic devices installed in
vehicles as original equipment (OE).\10\ The Phase 2 Driver Distraction
Guidelines (Phase 2 Guidelines), which are the subject of this notice,
would apply to visual-manual interfaces of portable and aftermarket
devices.

---------------------------------------------------------------------------
While NHTSA is proposing the Phase 2 Guidelines, it is important to
note that the agency continues to support state efforts to prohibit
hand-held use of portable devices while driving. In proposing the Phase
2 Guidelines, NHTSA stresses that it does not encourage the hand-held
use of portable devices while driving. While NHTSA acknowledges that
there are many available technology solutions, state laws, and consumer
information campaigns designed to help reduce distracted driving, the
agency believes that an important way to help mitigate the real-world
risk posed by driver distraction from portable devices is for these
devices to have limited functionality and simplified interfaces when
they are used by drivers while driving. This is especially true because
some of these devices are intended to be used while driving and others
have applications that are clearly meant to be used by drivers to
complete the driving task. These Guidelines are, therefore, intended to
reduce the potential distraction associated with hand-held portable and
aftermarket device use while driving. The agency believes these
Guidelines will provide a framework for portable device and application
developers to take into account real-world device use by consumers when
driving. In addition, the agency notes that applications that are meant
to be used by drivers while driving are likely to continue to be
developed and made available.
While these Guidelines help manufacturers develop portable and
aftermarket devices while keeping safe driving in mind, it remains the
driver's responsibility to ensure the safe operation of the vehicle and
to comply with all state traffic laws. This includes, but is not
limited to laws that ban texting and/or the use of hand-held devices
while driving. NHTSA and the US DOT support and will continue to
support State and Federal efforts to combat distracted driving.
D. The Proposed NHTSA Guidelines for Portable and Aftermarket Devices
This notice announces the proposed Phase 2 Guidelines for Portable
and Aftermarket Devices. The Phase 1 Guidelines for OE in-vehicle
interfaces, discussed in detail below, provide the foundation for the
proposed Phase 2 Guidelines. Phase 1 provided specific recommendations
for minimizing the distraction potential from OE in-vehicle interfaces
that involve visual-manual interaction. Particularly, the Phase 1
Guidelines are focused on recommending acceptance criteria for driver
glance behavior where single average glances away from the forward
roadway are 2 seconds or less and where the sum of the durations of all
individual glances away from the forward roadway are 12 seconds or less
while performing a testable task, such as selecting a song from a
satellite radio station.
To the extent practicable, the Phase 2 Guidelines apply the Phase 1
recommendations to the visual-manual interfaces of portable devices
(e.g., smartphones, tablets, and navigation devices) and aftermarket
devices (i.e., devices installed in the vehicle after manufacture).
Because there are both similarities and differences between OE
interfaces and portable devices, the Phase 2 Guidelines primarily focus
on portable devices. Due to the functional similarities between
aftermarket devices and OE systems, the Phase 2 Guidelines direct
manufacturers to the Phase 1 Guidelines.
The proposed Phase 2 Guidelines present two concurrent approaches
for mitigating distraction associated with the use of portable and
aftermarket devices by drivers. First, the proposed Guidelines
recommend that portable and OE in-vehicle systems be designed so that
they can be easily paired to each other and operated through the OE in-
vehicle interface. Assuming that the OE in-vehicle interface conforms
to the Phase 1 Guidelines, pairing would ensure that the tasks
performed by the driver while driving meet the time-based, eye-glance
task acceptance criteria specified in the Phase 1 Guidelines. Pairing
would also ensure that certain activities that would inherently
interfere with the driver's ability to safely control the vehicle would
be locked out while driving (i.e., the ``per se lock outs'' referred to
in the Phase 1 Guidelines). Those per se lock outs include:
[[Page 87659]]
Displaying video not related to driving;
Displaying certain graphical or photographic images;
Displaying automatically scrolling text;
Manual text entry for the purpose of text-based messaging,
other communication, or internet browsing; and
Displaying text for reading from books, periodical
publications, Web page content, social media content, text-based
advertising and marketing, or text-based messages.
NHTSA encourages all entities involved with the engineering and
design of pairing technologies to jointly develop compatible and
efficient processes that focus on improving the usability and ease of
connecting a driver's portable device with their in-vehicle system.
The second approach recommended by the proposed Phase 2 Guidelines
is that portable devices that do not already meet the NHTSA glance and
per se lock out criteria when being used by a driver should include a
Driver Mode that is developed by industry stakeholders (i.e., Operating
System or handset makers).
The Driver Mode should present an interface to the driver that
conforms with the Phase 1 Guidelines and, in particular, locks out
tasks that do not meet Phase 1 task acceptance criteria or are among
the per se lock outs listed above. The purpose of Driver Mode is to
provide a simplified interface when the device is being used unpaired
while driving, either because pairing is unavailable or the driver
decides not to pair. The Guidelines recommend two methods of activating
Driver Mode depending on available technology. The first option, and
the one encouraged by the agency, is to automatically activate the
portable device's Driver Mode when: (1) The device is not paired with
the in-vehicle system, and (2) the device, by itself, or in conjunction
with the vehicle in which it is being used, distinguishes that it is
being used by a driver who is driving. The driver mode does not
activate when the device is being used by a non-driver, e.g.,
passenger.\11\
---------------------------------------------------------------------------
\11\ For purposes of this notice, ``passenger'' is a subset of
``non-driver.'' Non-drivers include not only personal vehicle
passengers, but also people riding mass transit, bicycling, and the
like. When referring to the specific type of vehicles this guidance
is aimed at--light vehicles--the notice will often refer to those
occupants as drivers and passengers and the technology that
distinguishes between drivers and passengers in light vehicles as
driver-passenger distinction technology.
---------------------------------------------------------------------------
NHTSA has learned that technologies to detect whether a driver or
passenger is using a device have been developed but are currently being
refined such that they can reliably detect whether the device user is
the driver or a passenger and are not overly annoying and
impractical.\12\ Accordingly, the agency is proposing a second means of
activation--manual activation of Driver Mode--meaning that Driver Mode
is activated manually by the user. The agency foresees this being a
temporary option in the Phase 2 Guidelines until driver-passenger
distinction technology is more mature, refined, and widely available.
The agency is optimistic such technology can be implemented as soon as
practicable.
---------------------------------------------------------------------------
\12\ For further discussion of driver-passenger distinction
technologies, see infra Section I.3.
---------------------------------------------------------------------------
Additionally, the Phase 2 Guidelines include recommendations for
aftermarket devices--those devices that are intended to be permanently
installed in the vehicle, which were not addressed in Phase 1. The
proposed Phase 2 Guidelines suggest that aftermarket devices meet the
same task acceptance criteria and other relevant recommendations as
specified for OE interfaces in Phase 1.
Due to the close relationship between the Phase 1 and Phase 2
Guidelines, the agency is considering combining the two phases into a
single document when the Phase 2 Guidelines are finalized. The agency
requests comment on whether a single combined document would be easier
for industry to use and the public at large to reference, or whether
separate documents would be simpler.
Because these proposed Guidelines are voluntary and nonbinding,
they will not require action of any kind, and for that reason they will
not confer benefits or impose costs. Nonetheless, and as part of its
continuing research efforts, NHTSA welcomes comments on the potential
benefits and costs that would result from voluntary compliance with the
Guidelines.
E. Major Differences Between the Proposed Phase 2 and Phase 1 NHTSA
Guidelines
The Phase 1 Guidelines recommend that interfaces and tasks
determined to be more distracting than a specified level should not be
accessible to the user while the user is driving. Similarly,
conformance with the proposed Phase 2 Guidelines would result in
drivers interacting with their paired portable devices through Phase 1-
conforming OE, built-in interfaces. In many cases, it is up to the
driver to pair his or her device with the vehicle's interface or, as in
the case with many older vehicles, the vehicle does not have the
capability to pair with a portable device, so the Phase 2 Guidelines
also recommend that the portable device be put in Driver Mode for use
while driving instead of the portable device's default interface.
There are several distinctions between portable devices and in-
vehicles systems that result in different considerations between the
Phase 1 and Phase 2 Guidelines. The first distinction is that many
portable devices are designed with the intent of being used in a
variety of contexts that may or may not include driving, whereas OE in-
vehicle interfaces are designed specifically for use while driving
(unless specific functions are inaccessible when the vehicle is in
motion). As a result, it is important that the Phase 2 Guidelines
account for the need to reliably identify when a portable device is in
fact being used by the driver of a moving vehicle.
A second distinction between portable devices and in-vehicle
systems is that the portable devices may be used by other vehicle
occupants in locations where the driver cannot see or access the
device, e.g., by a passenger in the back seat. In contrast, all of the
interaction with the OE in-vehicle interface occurs in the vehicle, and
the location of the interface (and whether the driver can access it) is
known to the vehicle manufacturer when the interface is designed and
installed.\13\ These differences between the portable device and OE in-
vehicle interface can be overcome with technological solutions, as
described in greater detail below, potentially allowing for a Driver
Mode that activates when the portable device is used by a driver while
driving. This would allow for the device to be used in its full
capacity in non-driving situations. Therefore, NHTSA encourages the
development and implementation of technologies that can distinguish
between drivers and passengers.
---------------------------------------------------------------------------
\13\ The Phase 1 Guidelines explicitly exclude OE in-vehicle
devices that cannot reasonably be reached or seen by the driver.
---------------------------------------------------------------------------
A third distinction between portable devices and in-vehicle systems
is that, if not paired with the in-vehicle system, portable devices can
be placed and/or mounted in a variety of different locations in the
vehicle. There is also variability in the placement of an aftermarket
device--although to a lesser extent than for portable devices, since
aftermarket devices are confined to the available locations on the
vehicle, such as inside the center stack or on top of the dashboard.
NHTSA has elected not to include recommendations concerning whether or
where a portable device should be mounted in this proposed set
[[Page 87660]]
of guidelines, but we seek comment on whether we should include them at
a later date and whether there are already other entities/programs that
provide advice on where to mount devices safely.
A fourth distinction is that the user-interface experience with
portable devices can be different from built-in and installed
aftermarket systems due to a wide range of device characteristics
(e.g., smaller screens on portable devices). In addition, users often
use their thumbs to interact with touchscreens on hand-held portable
devices, whereas the index finger is more commonly used with built-in
and installed aftermarket systems. While these differences in device
characteristics may affect a driver's interaction with the device,
NHTSA believes it is unnecessary to address design issues at the
characteristic level for the Phase 2 Guidelines, because, regardless of
their specific features, portable devices will be used while within
reach of the driver and viewed at a downward viewing angle. Rather,
NHTSA maintains its focus on the Phase 1 test procedures and acceptance
criteria in Phase 2 for paired and unpaired portable devices, as well
as installed aftermarket devices.
The variability of potential locations for portable and aftermarket
devices has implications for testing procedures to determine
conformance with our recommendations concerning Driver Mode.
Specifically, the proposed Phase 2 Guidelines' test procedure for when
the device is in Driver Mode includes recommendations about the
placement of the portable electronic devices during testing. In order
to address the issues mentioned above regarding the variability of the
portable device's location and driver's access to its screen, the
proposed test procedure recommends that unpaired portable devices be
tested in a mounted location that is easy for the driver to reach and
is based on driver viewing angle specified in Phase 1. NHTSA has
included a general recommended testing location for unpaired portable
devices but seeks comment on whether a location could be specified that
would not result in infinite possibilities or be too particular to any
one device or vehicle.
For aftermarket devices that are intended to be permanently
installed in the vehicle, the proposed test procedure recommends that
they be tested in the installation location prescribed by the device
manufacturer.
F. Phase 2 Outreach Efforts
NHTSA is committed to reducing deaths and injuries resulting from
motor vehicle crashes from distraction by encouraging the development
of devices that can be safer if used while driving. As part of the
ongoing process of harmonizing with industry standards and practices,
NHTSA hosted a public meeting on March 12, 2014, to bring together
vehicle manufacturers and suppliers, portable and aftermarket device
manufacturers, portable and aftermarket device operating system
providers, cellular service providers, industry associations,
application developers, researchers, and consumer groups to discuss
technical issues regarding the agency's development of the Phase 2
Driver Distraction Guidelines for portable and aftermarket devices.
NHTSA held the public meeting to ensure the stakeholders' interests
were communicated and considered in the development of the Phase 2
Guidelines. NHTSA has met with portable and aftermarket device
manufacturers through the Consumer Technology Association (CTA) \14\
working group as well as individual meetings as part of an ongoing
effort to enhance the cooperation and coordination of the Distraction
Guidelines. Likewise, NHTSA participated in U.S. Senator John (Jay) D.
Rockefeller's ``Over-Connected and Behind the Wheel: A Summit on
Technological Solutions to Distracted Driving'' on February 6, 2014.
Sen. Rockefeller, chair of the Senate Committee on Commerce, Science,
and Transportation, hosted the summit to address potential
technological solutions for minimizing driver distraction. NHTSA has
also met with majority and minority staff members from several House
and Senate Committees, including the House Energy and Commerce
Committee, the House Transportation and Infrastructure Committee, the
House Appropriations Committee, the Senate Commerce Committee, and the
Senate Appropriations Committee, in July 2014 to provide background on
the Phase 2 Guidelines and answer questions.
---------------------------------------------------------------------------
\14\ Following NHTSA's Phase 2 Guidelines public meeting but
before the issuance of this notice, the Consumer Electronics
Association changed its name to the Consumer Technology Association.
This notice will refer to that entity as the Consumer Technology
Association or CTA unless the name is used in a publication title or
citation.

II. Background
A. Overview
Driver distraction is a safety problem in the United States. The
latest crash and fatality data implicate driver distraction in 10
percent of fatal crashes, 18 percent of injury crashes, and 16 percent
of all motor vehicle traffic crashes in 2014.\15\ The 2014 data show
that cell phones were directly linked to 385 fatal crashes (resulting
in 404 fatalities), which is 13 percent of all distraction affected
crashes and 1.3 percent of all fatal crashes.\16\ The following
sections outline the definition of driver distraction, the prevalence
of portable device use in motor vehicles, and the crash and crash risk
data associated with distraction from all devices in general and
portable device use specifically. This section also outlines the
various efforts from the US DOT, industry, and safety advocates to
combat the distraction problem. These efforts include improving our
understanding of the distraction problem, the implementation of
legislation and enforcement approaches, driver education and public
awareness campaigns, and guidelines for industry to develop less
distracting devices and driver-vehicle interfaces.

---------------------------------------------------------------------------
B. Definition and Scope of Driver Distraction
Driver distraction is a specific type of inattention that occurs
when drivers divert their attention away from the driving task to focus
on another activity. These distractions can come from electronic
devices, such as navigation systems and cell/smartphones, and from more
conventional activities, such as viewing sights or events external to
the vehicle, interacting with passengers, and/or eating. These
distracting tasks can affect drivers in different ways, and can be
broadly categorized into the following types:
Visual distraction: Tasks that require the driver to look
away from the roadway to visually obtain information;
Manual distraction: Tasks that require the driver to take
one or both hands off the steering wheel to manipulate a control,
device, or other non-driving-related item;
Cognitive distraction: Tasks that require the driver to
avert their mental attention away from the driving task.
Any given task can involve one, two, or all three of these types of
distraction. NHTSA is aware of the effect that these types of
distraction can have on driving
[[Page 87661]]
safety, particularly visual-manual distraction.
The impact of distraction on driving is determined from multiple
criteria, the type and level of distraction, and the frequency and
duration of task performance. Even if performing a task results in a
low level of distraction, a driver who engages in it frequently, or for
long durations, may increase the crash risk to a level comparable to
that of a more difficult task performed less often.
C. Prevalence of Portable Device Use While Driving
NHTSA is concerned about the role of portable electronic devices in
distracted driving crashes. NHTSA has been monitoring drivers' use of
portable devices through its National Occupant Protection Use Survey
(NOPUS),\17\ which involves the direct observation of driver electronic
device use at probabilistically-sampled intersections. The most recent
available NOPUS data from 2015 showed that 2.2 percent of drivers were
observed manipulating hand-held devices, 3.8 percent of drivers were
observed holding cell phones to their ears while driving, and 0.6
percent of drivers were observed speaking into visible headsets while
driving. Notably, the percentage of drivers visibly manipulating hand-
held devices has nearly quadrupled from 0.6 percent in 2009 to 2.2
percent in 2015, whereas the percentage of drivers holding cell phones
decreased from 5 percent in 2009 to 3.8 percent in 2015. The percentage
of drivers speaking into visible headsets has fluctuated from 0.6
percent in 2009, to as high as 0.9 percent in 2010, and as low as 0.4
percent in 2014.

---------------------------------------------------------------------------
Surveys of drivers indicate even higher rates of portable device
use while driving. According to a 2012 survey published by NHTSA,\18\
14 percent of drivers reported reading text messages and email while
driving at least some of the time, and 10 percent of drivers reported
sending text or email messages while driving at least some of the time.
In addition, almost half of drivers reported answering their cell phone
when driving at least some of the time, and more than half of drivers
who reported answering their phones while driving said they will
continue to drive while talking on the phone. The survey further
indicated that almost a quarter of drivers reported that they are at
least sometimes willing to make a cell phone call while driving. As
will be seen, these visual-manual distraction activities are associated
with increased crash and near-crash risk.

Survey on Distracted Driving Attitudes and Behaviors--2012 (DOT HS

Administration.
---------------------------------------------------------------------------
NHTSA's 2013 Cell Phone Naturalistic Driving Study \19\ found that
28 percent of the calls and 10 percent of the text messages in the
participant cell phone records overlapped with periods of driving. In
terms of visual-manual task duration while interacting with the cell
phone, dialing on a hand-held cell phone lasted 12.4 seconds (s), on
average, while pushing a button to begin a hands-free cell phone call
(either with an aftermarket ``portable'' hands-free device or with a OE
built-in, hands-free connection) took significantly less time (averages
were 2.9 s and 4.6 s, respectively). Texting interactions lasted 36.4
s, on average (Min = 0.3 s, Max = 450.1 s), while driving at speeds
above 8 km/h (approximately 5 mph). The study also assessed call
duration as a function of hand-held, portable hands-free (e.g.,
aftermarket headset), and integrated hands-free (e.g., wireless
connection to vehicle system). When driving at speeds above 8 km/h
(approximately 5 mph), drivers talked longer on portable hands-free
cell phones (4.96 min on average) than on integrated hands-free cell
phones (3.78 minutes on average) or hand-held cell phones (3.00 min on
average). However, the study found no differences in the number of text
messages made per minute as a function of hand-held, portable hands-
free, and integrated hands-free cell phones.

---------------------------------------------------------------------------
In a more recent survey by the AAA Foundation for Traffic
Safety,\20\ which focused on driving habits during the 30 days prior to
the survey, 34.7 percent of drivers reported reading a text or email
messages while driving, and 25.8 percent of drivers reported typing or
sending text or email messages while driving. Additionally, 67.1
percent of drivers reported talking on a cell phone (of any kind,
including while using a wireless connection and speaker phone) while
driving during this period. These data show that many drivers continue
to engage in visual- manual distraction activities with their portable
devices while driving. This is concerning because research by NHTSA and
others suggests that visual-manual manipulation of devices while
driving dramatically increases crash risk.

The portable device market generally consists of portable devices
including smartphones, tablets, navigation devices, and portable music
players (e.g., mp3 players). The aftermarket device market generally
consists of products that are installed in a vehicle after its initial
purchase, such as car stereos and navigation systems. Access to content
(such as music and podcasts) has greatly increased over recent years,
as have the capabilities of these devices and the public's desire to
stay connected through them while driving. Accordingly, the scope of
stakeholders has grown to include automotive OE manufacturers, handset
(e.g., smartphone) manufacturers, application (app) developers,
wireless carriers, and software operating system providers. Through
various meetings with these wide-ranging stakeholders, NHTSA recognizes
the complexity of this stakeholder ``ecosystem'' and that distraction
guidelines are currently not available for designing portable device
user interfaces for safe use while driving. As a result, the
Distraction Guidelines will provide a uniform safety framework for
these stakeholders when integrating or developing their products for
driving use.
D. Driver Distraction Safety Problem
The significant safety impact of distracted driving is evident from
NHTSA's crash data, which comes from the Fatality Analysis Reporting
System (FARS) \21\ and the National Automotive Sampling System (NASS)
General Estimates System (GES).\22\ In 2014,\23\ 10 percent of all
fatal crashes involved one or more distracted drivers,\24\ and these
distraction-affected crashes \25\ resulted
[[Page 87662]]
in 3,197 fatalities.\26\ This number increased 8.8 percent to 3,477
fatalities in 2015.\27\ Of the 6 million non-fatal, police-reported
crashes in 2014, 16 percent (967,000) were distraction-affected crashes
and resulted in 431,000 people injured. Tables 1 and 2 quantify the
effects of distraction on fatal crashes from 2010 to 2014 \28\ and non-
fatal crashes from 2007 through 2014.\29\ These data show that
distraction-affected fatalities and crashes continue to be a concern,
and that NHTSA's ongoing efforts to address driver distraction from
multiple approaches, including through its Guidelines, are warranted.
---------------------------------------------------------------------------
\21\ FARS is a census of all fatal crashes that occur on the
roadways of the United States of America. It contains data on all
fatal crashes occurring in all 50 states as well as the District of
Columbia and Puerto Rico.
\22\ NASS GES contains data from a nationally-representative
sample of police-reported crashes. It contains data on police-
reported crashes of all levels of severity, including those that
result in fatalities, injuries, or only property damage. National
numbers of crashes calculated from NASS GES are estimates.

(last accessed on 10/4/16).
\28\ Because of changes made in 2010 to the coding of distracted
driving in FARS, distraction-affected crash data from FARS for 2010
through 2014 cannot be compared to distracted-driving-related data
from FARS from previous years.
\29\ The coding of distracted driving in FARS and NASS GES was
unified beginning in 2010. Although this resulted in a coding change
for FARS, NASS GES coding did not change. Accordingly, NASS GES data
from 2007 through 2014 can be compared.

E. Driver Distraction and Portable Devices
1. Crash Data
The crash data indicate that the use of portable and aftermarket
devices, particularly cell phones, is often a leading distraction for
drivers involved in crashes (note that smartphones reached significant
market presence beginning in 2007). In 2014, there were 385 fatal
crashes that involved the use of a cell phone, though it is possible
that this is an underestimate due to the difficult nature in relating
cell phone use to crashes at the crash scene. These cell phone fatal
crashes represented 13 percent of the total distraction-affected fatal
crashes. The data also indicate that there were 75 distraction-affected
fatal crashes in 2014 that involved the driver using or reaching for a
device or object brought into the vehicle. This catch-all category of
fatal distraction crashes includes crashes that involved the use of
portable devices such as navigation devices in addition to other types
of objects (e.g., pocket cigarette lighters).
Of the 967,000 distraction-affected crashes in 2014, 8 percent
(69,000 crashes) involved the use of cell phones, resulting in 33,000
people injured. The tables below quantify the effects of cell phone or
other device use on fatal crashes from 2010 through 2014 and non-fatal
crashes that involved the use of cell phones or other devices from 2007
through 2014.\30\ As with Tables 1 and 2, these data show that cell
phone-affected fatalities and crashes continue to pose a risk to motor
vehicle safety.
---------------------------------------------------------------------------
\30\ Identification of specific distractions has presented
challenges, both within NHTSA's data collection and on police
accident reports. Therefore, a large portion of the crashes that are
reported to involve distraction do not have a specific behavior or
activity listed; rather they specify ``distraction/inattention,
details unknown.'' Some portion of these crashes could have involved
a portable or aftermarket device.

2. Crash Risk Associated With Portable Device Use
---------------------------------------------------------------------------
\36\ Possible reasons for the uptick between 2010 and 2014
include the increasing volume of smartphones in the market and
better distraction-related crash reporting.
---------------------------------------------------------------------------
The majority of crash risk data related to portable devices has
focused on cell phones. However, it is important to note that cell
phones have evolved from a portable hand-held phone designed
specifically for voice calls to a device that can be used for various
forms of communication, entertainment, and access to content. Examples
include applications developed for messaging, photo-sharing, gaming,
social networking, navigation, and other location-based services. While
these features are not intended to be used while driving, they remain
just as accessible to the driver in driving situations as any other
feature on a smartphone. Whether on smartphones, tablet computers, or
other portable electronic devices, access to more content can lead to
more visual-manual distraction, which the studies summarized below
consistently show is associated with higher levels of crash and near-
crash risk, and decreased driving performance.
The agency's distraction focus has been on research and test
procedures that measure aspects of driver performance having the
strongest connection to crash risk. As described below, interactions
with a distraction task that require visual attention (i.e., eyes-off-
road time) and manual operations (e.g., button presses) consistently
show association with increased crash and near-crash risk in
naturalistic driving studies and decreased driving performance in
simulator and test-track studies. The research summarized below
provides a brief overview of the distraction safety problem as
manifested in crashes and the relationship between visual-manual
distraction and crash risk. There are also many simulator and test-
track studies that show the negative effects of distracted driving have
on driving performance that are not included in the summary below.\37\
---------------------------------------------------------------------------
\37\ A sample of simulator and test-track study reports can be
found at www.distraction.gov.
---------------------------------------------------------------------------
A key component of the NHTSA distraction plan is to understand the
crash risk of drivers using a cell phone while driving. Early
epidemiological research reported that using a cell phone, hand-held or
hands-free, was associated with a quadrupling of the risk of injury and
property damage
[[Page 87664]]
crashes.38 39 Subsequent naturalistic driving studies that
investigated the risk of drivers performing specific cell phone
subtasks all found that increased crash risk and safety critical event
risk (SCE) were associated with visual-manual operations such as text
messaging and dialing. An SCE was defined as a crash (where contact was
made with another object), a near-crash (where a crash was avoided by a
rapid evasive maneuver), or a crash-relevant conflict (where a crash
avoidance response was performed that was less severe than a rapid
evasive maneuver, but greater in severity than a ``normal maneuver'').
However, in the naturalistic studies, non-visual-manual operations,
such as conversing on a cell phone, were not found to be associated
with an increase in crash risk.40 41 42 These results were
observed for both commercial motor vehicle and light-vehicle drivers,
as well as across broad classifications of low, moderate, and high
driving task demands.\43\ In contrast, research conducted in simulators
and on test tracks has found driving performance decrements when
driving while talking on a cell phone.44 45 46 47 These
experiments, however, cannot directly connect their results to SCE
risk.

In April 2013, NHTSA published a study \48\ on the impact of hand-
held and hands-free cellular phone use on crash risk and driving
performance. The study investigated the effects of distraction from the
use of three types of cell phones while driving: (1) Hand-held (HH),
(2) portable hands-free (PHF), and (3) integrated hands-free (IHF).
Seventy-five percent of the phones used in the study could be
classified as smartphones. Naturalistic driving data was collected from
204 drivers who each voluntarily took part in the study for an average
of 31 days from February 2011 to November 2011. All participants
reported talking on a cell phone while driving at least once per day
prior to entering the study. With the participants' knowledge, data
acquisition systems were installed in their personal vehicles and
continuously recorded video of the driver's face, the roadway, and
various kinematic data such as the vehicle speed, acceleration, headway
information to lead vehicles, steering, and location. This was the
first naturalistic driving study to date in which participants provided
their cell phone records for analysis. The cell phone records allowed
the determination of when drivers used their cell phone, while the
video data allowed the determination of the type of cell phone used,
how long it was used for, and what subtasks were executed. The result
was a rich data set of driver behavior and performance when using a
cell phone.

---------------------------------------------------------------------------
SCE risk was investigated using two approaches: (1) A risk rate
approach, which assessed the SCE risk relative to general driving
(where non-cell-phone secondary tasks could occur), and (2) a case-
control approach, which assessed the SCE risk relative to ``just
driving'' (where non-driving-related secondary tasks did not occur).
The risk rate results are shown below (see the full report for the
case-control results along with driver performance results). The odds
ratio indicates the relative risk of an SCE during the listed activity.
An odds ratio value of 1.0 is considered equivalent to driving while
not distracted. Odds ratio values above 1.0 indicate elevated risk and
values below 1.0 indicate decreased risk, though the difference must be
statistically significant (i.e., reliably different) for conclusions to
be drawn about the associated risk of that activity.

The risk rate approach generates a powerful estimate of risk by
using all accounts of when cell phones were used while driving.
However, it cannot assess the SCE risk relative to ``just driving''
(defined as driving void of all non-driving-related secondary tasks)
without the availability of estimates of the propensity for each
potential secondary task that is performed while driving. The case-
control approach was thus used to address this limitation. A total of
2,308 baseline periods were randomly sampled based on each driver's
driving time in the study. This number was selected to be at least four
times the 342 SCEs that were identified. The odds of an SCE occurring
during specific cell phone subtasks were then compared to the odds of
an SCE occurring when just driving. Note that ``just driving'' was only
found in 46 percent of the baseline periods. Table 6 presents the odds
ratios (ORs) and 95-percent confidence limits for various cell phone
subtasks. As in the previous risk analysis, only VM subtasks performed
on an HH cell phone were found to be associated with an increased SCE
risk. Conversing on a cell phone (i.e., any type of cell phone) was not

* Indicates a difference at the .05 level of significance.
The overall results from the study presented a clear finding:
Visual-manual subtasks performed on hand-held cell phones degraded
driver performance and increased SCE risk. Although current hands-free
cell phone interfaces allow drivers to communicate with their voices,
there is a concern that they still require visual-manual interactions.
In fact, drivers in this study frequently initiated hands-free calls
and performed other visual-manual operations (e.g., texted) with a
hand-held cell phone. A notable finding was that approximately half of
the hands-free cell phone interactions in this study were found to
involve visual-manual interactions with the hand-held phone. These
findings that implicate visual-manual distraction as the primary
distraction risk are consistent with previous naturalistic driving
investigations of crash risk related to cell phone subtasks,\49\
including the 100-Car Naturalistic Driving Study.50 51 52 53

F. Overview of Efforts To Combat Driver Distraction
Recognizing the distraction safety issue outlined above, NHTSA
published the ``Overview of the National Highway Traffic Safety
Administration's Driver Distraction Program,'' \54\ in April 2010. This
plan consisted of four main initiatives:
---------------------------------------------------------------------------
\54\ NHTSA. (2010). Overview of the National Highway Traffic
Safety Administration's Driver Distraction Program, (DOT HS 811
299). Available at http://www.nhtsa.gov/staticfiles/nti/distracted_driving/pdf/811299.pdf (last accessed on 10/4/16).
---------------------------------------------------------------------------
1. Improve the understanding of the extent and nature of the
distraction problem. This includes improving the quality of data NHTSA
collects about distraction-related crashes and improving analysis
techniques.
2. Reduce the driver workload associated with performing tasks
using original equipment, aftermarket, and portable in-vehicle
electronic devices by working to limit the visual, manual, and
cognitive demand associated with secondary tasks performed using these
devices. Better device interfaces will minimize the time and effort
involved in a driver performing a task using the device. Minimizing the
workload associated with performing secondary tasks with a device will
permit drivers to maximize the attention they focus toward the primary
task of driving. NHTSA's Driver Distraction Guidelines fall under this
initiative.
3. Keep drivers safe through the introduction of crash avoidance
technologies. These include the use of crash warning systems to re-
focus the
[[Page 87666]]
attention of distracted drivers as well as vehicle-initiated (i.e.,
automatic) braking and steering to prevent or mitigate distraction-
affected crashes. Research 55 56 57 58 on how best to warn
distracted drivers in crash imminent situations is also supporting this
initiative. NHTSA is also performing a large amount of research on
automatic emergency braking technologies (e.g., crash warning systems
or automatic braking systems) and dynamic brake support.

4. Educate drivers about the risks and consequences of distracted
driving. This includes targeted media messages, drafting and publishing
sample text-messaging laws for consideration and possible use by the
states, testing high-visibility enforcement programs, and publishing
guidance for a ban on text messaging by Federal government employees
while driving.
In June 2012, the US DOT released a ``Blueprint for Ending
Distracted Driving.'' \59\ This was an update of the ``Overview of the
National Highway Traffic Safety Administration's Driver Distraction
Program.'' These two documents summarize NHTSA's planned steps to
``help in its long-term goal of eliminating a specific category of
crashes--those attributable to driver distraction.''

10/4/16).
---------------------------------------------------------------------------
Industry and safety advocacy groups have also been working to
eliminate driver distraction using education and public awareness
campaigns, as well as through design guidance for built-in systems and
other aftermarket solutions. The following sections highlight the
efforts by NHTSA and the US DOT in legislative and enforcement
approaches, education and public awareness approaches, and device-based
solutions (e.g., guidelines or products), as well as similar efforts by
industry and safety advocates
G. Efforts by States To Address Distracted Driving Involving the Use of
Portable Devices
Most states, with the support of NHTSA and the US DOT, have passed
laws to limit the use of portable devices while driving. Currently, 46
states, DC, Puerto Rico, Guam, and the U.S. Virgin Islands ban texting
while driving for drivers of all ages. Fourteen states, DC, Puerto
Rico, Guam, and the U.S. Virgin Islands ban drivers of all ages from
using hand-held cell phones while driving.
In 2012, NHTSA partnered with the State of California and the State
of Delaware to initiate a high-visibility enforcement (increased police
presence supported by paid and earned media) demonstration program in
the Sacramento area of California and in the State of Delaware in
support of laws banning the use of hand-held cell phones while driving.
Three waves of enforcement were conducted between October 2012 and June
2013. The featured tagline for the public face of the program was
``Phone in one Hand, Ticket in the Other.'' During the study period, a
small percentage of crashes were coded as distraction-related, but the
crash data analyses did not reveal any apparent effect of the high-
visibility enforcement on the incidence of distraction-related crashes.
Driver surveys, however, showed an increase in awareness that cell
phone laws were being enforced. Observed hand-held driver cell phone
use dropped by one-third from 4.1 percent to 2.7 percent in California
(a 34% reduction); and from 4.5 percent to 3.0 percent in Delaware (a
33% reduction). The study concluded that high-visibility enforcement
can be implemented over wide-spread, multi-jurisdictional areas and
reduce the number of people who use a hand-held cell phone while
driving.\60\

H. Education and Public Awareness Efforts
1. Government Programs and Efforts
The US DOT and NHTSA have put considerable effort toward reaching
out to the community and the various stakeholders since the emergence
of distracted driving as a traffic safety concern. The US DOT and NHTSA
conducted two national summits, one in 2009 and one in 2011, to bring
attention to the issue.
Following these distraction summits, NHTSA has held several
meetings with stakeholders such as representatives of the automotive
and communications industries as well as researchers and other key
leaders to continue the public policy discussion on the distracted
driving issue. For the public, NHTSA has created a Web site,
www.distraction.gov, to provide timely information on distracted
driving and current information on related research and development
activities.
NHTSA has had, and continues to use, public service messages to
change the attitudes and behaviors of drivers through social norming
and enforcement messages. Social norming messaging is designed to
appeal to the individual to change their behavior because it is the
socially acceptable thing to do without an underlying theme related to
deterrence (e.g. ``One text or call could wreck it all''). The
enforcement messages were designed to be used in conjunction with high
visibility enforcement programs to promote compliance with distracted
driving laws or face the possible of an enforcement encounter (e.g. ``U
Drive U Text U Pay.'') Several messages in each category have been used
since the inception of the distracted driving prevention effort.
NHTSA has also made efforts to reach out into the community on the
issue of distracted driving through social media (e.g. ``Twitter
parties'') and blogs. There have also been a number of webinars for
stakeholders and the public to familiarize them with recent
developments in the effort to understand and reduce distractive driving
behavior.
On February 6, 2014, the Senate Committee on Commerce, Science, and
Transportation, led by Senator Jay Rockefeller (West Virginia), held a
summit that focused on addressing potential technological solutions for
minimizing driver distraction. The summit consisted of three roundtable
sessions: (1) The State of Distracted Driving, (2) The State of
Technology, and (3) Where do we go from there? Participants in all
three of these roundtables consisted of Federal agencies, safety
advocacy groups, industry associations, and companies from the
automobile, consumer electronics, technology, and communications
industries. The summit facilitated a dialogue between the various
organizations, encouraging all participants to continue working
together technologically to reduce the negative impacts of driver
distraction.
[[Page 87667]]
2. Industry Programs and Efforts
A range of industry stakeholders have also put forth an effort to
educate drivers on the dangers of distracted driving. While there are
too many education and public service announcement campaigns from
industry and information outlets to list in this notice, two recent
efforts by the wireless industry are included as examples (see
www.distraction.gov for a larger set of examples). As early as 1999,
the wireless industry expended considerable effort to promote driver
education about distracted driving. Most recently, the wireless
industry partnered with the National Safety Council for the ``On the
Road, Off the Phone'' campaign, which was directed at parents and
younger drivers and focused on the dangers of texting while driving. In
another campaign, AT&T began the ``It Can Wait'' education and
awareness initiative recently, and garnered partnerships with several
wireless carriers including Verizon Wireless, Sprint, and T-Mobile, as
well as an endorsement from the CTIA--The Wireless Association.
I. Design Guideline Efforts
1. NHTSA's Phase 1 Visual-Manual Driver Distraction Guidelines
As part of NHTSA's efforts to reduce driver workload associated
with performing tasks using devices within the vehicle (original
equipment, aftermarket, and portable in-vehicle electronic devices) the
agency has been developing Driver Distraction Guidelines for these
devices. NHTSA issued its first phase of driver distraction guidelines
on April 26, 2013, after notice and comment.\61\ NHTSA's Phase 1
Visual-Manual Driver Distraction Guidelines cover OE in-vehicle
electronic devices that are operated by the driver through visual-
manual means (i.e., the driver looks at a device, manipulates a device-
related control with his or her hand, and/or watches for visual
feedback from the device). The Phase 1 Guidelines cover any OE
electronic device that the driver can easily see and/or reach, even if
intended for use solely by passengers. However, the Phase 1 Guidelines
do not cover any device that is located fully behind the front seat of
the vehicle or any front-seat device that cannot readily be reached or
seen by the driver.
---------------------------------------------------------------------------
\61\ 78 FR 24817 (Apr. 26, 2013).
---------------------------------------------------------------------------
To facilitate the development of these guidelines, NHTSA studied
existing guidelines relating to driver distraction prevention and
reduction and found the ``Statement of Principles, Criteria and
Verification Procedures on Driver-Interactions with Advanced In-Vehicle
Information and Communication Systems'' developed by the Alliance of
Automobile Manufacturers (Alliance Guidelines) to be the most complete
and up-to-date. The Alliance Guidelines provided valuable input in
NHTSA's efforts to address driver distraction issues. Although NHTSA
drew heavily on that input in developing the Phase 1 Guidelines, the
agency identified a number of aspects that could be improved upon in
order to further enhance driving safety, enhance guideline usability,
improve implementation consistency, and incorporate the latest driver
distraction research findings.
The Phase 1 Guidelines are based upon a number of fundamental
principles. These principles include that:
The driver's eyes should usually be looking at the road
ahead;
The driver should be able to keep at least one hand on the
steering wheel while performing a secondary task (both driving-related
and non-driving related);
The distraction induced by any secondary task performed
while driving should not exceed that associated with a baseline
reference task (manual radio tuning);
Any task performed by a driver should be interruptible at
any time;
The driver, not the system/device, should control the pace
of task interactions; and
Displays should be easy for the driver to see and content
presented should be easily discernible.
The Phase 1 Guidelines list certain activities that inherently
interfere with a driver's ability to safely control the vehicle, and
the Guidelines recommend that in-vehicle devices be designed so that
they cannot be used by the driver to perform these inherently
distracting activities while driving (referred to as ``per se lock
outs''). The basis for these lock outs includes activities that are
discouraged by public policy and, in some instances, prohibited by
Federal regulation and/or State law (e.g., entering or displaying text
messages). They also include activities identified in industry driver
distraction guidelines, which NHTSA agrees are likely to distract
drivers significantly (e.g., displaying video or automatically
scrolling text). Finally, the lock outs include activities that are
extremely likely to be distracting due to their very purpose of
attracting visual attention, but whose obvious potential for
distraction cannot be measured using a task timing system because the
activity could continue indefinitely (displaying video or certain
images). The specific per se lock outs are as follows:
Displaying video not related to driving;
Displaying certain graphical or photographic images;
Displaying automatically scrolling text;
Manual text entry for the purpose of text-based messaging,
other communication, or internet browsing; and
Displaying text for reading from books, periodical
publications, Web page content, social media content, text-based
advertising and marketing, or text-based messages.
The per se lock out recommendations are not intended to prevent the
display of images related to driving such as simple, two-dimensional
map displays for the purpose of navigation, which would conform to
these Guidelines, as long as they are displayed in a safe manner. These
recommendations are also not intended to prevent the display of
internationally standardized symbols and icons, TrademarkTM
and Registered[supreg] symbols (such as company logos), or images
intended to aid a driver in making a selection in the context of a non-
driving-related task, provided that the images extinguish automatically
upon completion of the task.
For all other visual-manual secondary tasks, the Phase 1 Guidelines
specify two alternative test methods for measuring the impact of
performing a task on driving safety, as well as time-based acceptance
criteria for assessing whether a task interferes too much with driver
attention. It should be noted that secondary task is a broad term that
captures any interaction the driver has with an in-vehicle device that
is not directly related to the safe operation and control of a vehicle,
and thus captures all non-driving-related tasks as well as driving-
related tasks that aid the driving task but not the safe operation or
control of the vehicle. If a visual-manual secondary task does not meet
the acceptance criteria, the Phase 1 Guidelines recommend that OE in-
vehicle devices be designed so that the task cannot be performed by the
driver while driving. Both of these test methods focus on the amount of
visual attention necessary to complete a task. Eye-glance-based
criteria were selected because the research on visual-manual
distraction establishes a link between visual attention (eyes off the
road) and crash risk.
The first recommended test method measures the amount of time that
the driver's eyes are drawn away from the forward roadway while
performing a
[[Page 87668]]
task. The Phase 1 Guidelines recommend that devices be designed so that
tasks can be completed by the driver while driving with individual
glances away from the roadway of 2 seconds or less and a cumulative
time spent looking away from the roadway of 12 seconds or less. The
second test method uses a visual occlusion technique and involves
participants performing a task using occlusion goggles that
alternatively open and shut every 1.5 seconds. The Phase 1 Guidelines
recommend that devices be designed so that tasks can be completed with
a cumulative shutter open time of 12 seconds or less.
In addition to identifying inherently distracting tasks and
providing a means to measure and evaluate the level of distraction
associated with other secondary tasks, the Phase 1 Guidelines contain
other recommendations for in-vehicle devices designed to limit and
reduce their potential for distraction. Examples include a
recommendation that performance of visual-manual tasks should not
require the use of more than one hand, a recommendation that each
device's active display be located as close as practicable to the
driver's forward line of sight, and a recommended maximum downward
viewing angle to the geometric center of each display.
In the notice announcing the Phase 1 Guidelines, the agency
clarified that because the Guidelines were voluntary and non-binding,
NHTSA's normal enforcement procedures related to Federal Motor Vehicle
Safety Standard (FMVSS) compliance were not applicable. However, NHTSA
indicated that as part of its ongoing distraction research activities,
the agency does intend to monitor manufacturers' voluntary adoption of
the Phase 1 Guidelines.
2. Efforts by Industry To Address Driver Distraction From Portable
Devices
Various efforts focused on portable and aftermarket devices have
been initiated by industry to address driver distraction. In July 2013,
the Consumer Technology Association (CTA), an association comprised of
2,000 companies within the consumer technology industry, initiated a
Working Group focused on addressing portable and aftermarket electronic
devices used by drivers in vehicles (formally named R6 WG18 Driver-
Device Interface Working Group). Through mid-2014, the group had the
goal of developing industry-based guidelines for portable device design
that would address driver distraction. As indicated in a letter to the
agency, the group had planned to use the NHTSA Phase 1 Guidelines as a
starting point. The focus of this group had been to create a set of
recommended practices by bringing together industry stakeholders and
soliciting their technical input and expertise. These voluntary,
industry-based recommended practices were intended to be used by
portable electronic device manufacturers, software developers, and any
other interested parties to improve the safety of driving and non-
driving-related task performance. In mid-2014, the Working Group
abandoned its work to develop industry-based guidelines due to
liability concerns, instead modifying its overall objective to produce
a technical report that categorizes ``products and services offered by
the consumer electronics (CE) industry that help make the driving
experience safer.'' \62\ CTA's technical report surveying the existing
driver mode technologies was released in January 2015.\63\ NHTSA has
been participating in CTA's working group as a non-voting liaison since
its inception. NHTSA has provided explanations and rationale for
aspects of NHTSA's Phase 1 Visual-Manual Driver Distraction Guidelines,
and participated in discussions regarding the application of the
guideline's basic principles to the complex, multipart ecosystem of
portable and aftermarket electronic devices.

There have also been efforts within the standardization sector of
the International Telecommunications Union (ITU-T) \64\ to establish
international consensus-based distraction standards for Information and
Communications Technologies (ICTs). The ITU-T effort was intended to
establish interoperability standards that enable the vehicle to safely
manage driver interaction with ICT applications and services,
regardless of if they are downloaded to a vehicle or reside in a
roadside station, portable device, cloud-based server, etc. These
interoperability standards define functional mechanisms, data formats,
and communications protocols. The proposed ITU-T ``User Interface
Requirements for Automotive Applications'' (P.UIA Recommendation) would
provide design guidance for user interfaces, as well as recommended
test procedures and performance thresholds. As it stands, the published
P.UIA Recommendation only proposes a structure for the guidance. The
ITU-T's efforts were concluded in 2013 with the publication of several
reports.\65\
---------------------------------------------------------------------------
\64\ The International Telecommunication Union (ITU) is the
United Nations specialized agency in the field of
telecommunications, information and communication technologies
(ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is
a permanent organ of ITU. ITU-T is responsible for studying
technical, operating and tariff questions and issuing
Recommendations on them with a view to standardizing
telecommunications on a worldwide basis.

Distraction, which includes all reports that resulted from this
effort. Available at http://www.itu.int/en/ITU-T/focusgroups/distraction/Pages/default.aspx (last accessed on 10/4/16).
---------------------------------------------------------------------------
NHTSA is also participating as a liaison for a task group formed by
the Car Connectivity Consortium (CCC), the developers of Mirror Link,
to discuss the technical issues of device pairing, integration,
testing, and certification. Mirror Link represents a major industry
effort to enable and promote device pairing in vehicles. This effort
began in November 2014.
In addition to these formal industry efforts to produce best
practices, guidelines, and recommendations, several companies and
groups have demonstrated various technical solutions for aspects of the
distracted driving problem to NHTSA. These solutions include a driver
mode for portable devices, anti-texting software applications that
provide the capability to lock out the portable device screen, and
driver distinction technologies that are both vehicle- and portable-
device based. Each of these topics was included in NHTSA's Phase 2
Public Meeting in March 2014.
3. Public Meeting on the Phase 2 Distraction Guidelines
On March 12, 2014, NHTSA hosted a public meeting to bring together
vehicle manufacturers and suppliers, portable and aftermarket device
manufacturers, portable and aftermarket device operating system
providers, cellular service providers, industry associations,
application developers, researchers, and consumer groups to discuss
technical issues regarding the agency's development of Phase 2 Driver
Distraction Guidelines for portable and aftermarket devices. The
transcript for the public meeting and webcast video can be found in the
docket for today's proposed guidelines,\66\ along with
[[Page 87669]]
copies of all presentations and spoken remarks.

---------------------------------------------------------------------------
In the public meeting, NHTSA presented an overview of the Phase 1
Driver Distraction Guidelines and the key technical issues in Phase 2.
CTA presented a summary of its efforts to develop industry-based best
practices for portable and aftermarket devices that could be used by
drivers inside the vehicle. Following these presentations, there were
three panels of invited experts who addressed the following technical
topics: (1) Vehicle and portable/aftermarket device pairing, (2) Driver
Mode and advanced technologies, and (3) technologies that automatically
distinguish between devices used by drivers and passengers.
In its presentation about the Distraction Guidelines, NHTSA
highlighted the guiding principles for the guidelines along with the
technical approaches to Phases 1 and 2. NHTSA emphasized pairing
between the vehicle and portable devices as a means for incorporating
portable and aftermarket devices under the Phase 1 Distraction
Guidelines. NHTSA also discussed Driver Mode as an approach for
unpaired portable devices. NHTSA encouraged the development of
technology that can distinguish driver portable device use from
passenger portable device use. NHTSA noted that similar test procedures
and acceptance thresholds from Phase 1 would be applied to Phase 2.
Other issues under consideration for the Phase 2 Distraction Guidelines
included applicability to head-up displays and wearable devices, any
additional per se lock outs that might be required for portable and
aftermarket devices, placement of the portable device for testing, and
continuous display information that does not meet the Phase 1 task
definition. NHTSA concluded its presentation by highlighting the
general process for publishing the Phase 2 Distraction Guidelines.
Following NHTSA's presentation, CTA gave a presentation on its
Driver-Device Interface Working Group and activities for generating
industry-based best practices. In its presentation at the public
meeting, CTA noted that it believes best practices developed by
industry collaboration have the greatest chance of success in the
marketplace. Additionally, CTA recommended pairing. As of mid-2014, the
Working Group modified its objective, choosing to develop a technology
inventory instead of guidelines or recommendations.
The pairing panel consisted of presentations by General Motors,
Toyota, Delphi, and the Car Connectivity Consortium. The Driver Mode
and Advanced Technologies panel consisted of presentations by AT&T,
Garmin, and Pioneer. The Driver-Passenger Distinction panel consisted
of presentations by Cellcontrol, Cellepathy, and Lakeland Ventures
Development-Takata. NHTSA conducted a period of questions and answers
from the panelists after the presentations. NHTSA received additional
comments from Consumers Union, Origo, and Vesstech that were read from
the floor. Each of these presentations and spoken remarks can be found
in the Phase 2 docket.\67\

Comments: In response to the public meeting, eight comments were
posted to the docket by the Alliance of Automobile Manufacturers
(Alliance), Blackberry Limited, CTIA--The Wireless Association, General
Motors, Life Apps, the National Safety Council, Vesstech, and Consumers
Union. Seven of the eight commenters supported NHTSA's Phase 2
Distraction Guidelines, with only CTIA recommending that solutions to
portable device-based driver distraction be left solely to industry
collaborations. CTIA also challenged NHTSA's authority to issue
regulations, or even voluntary guidelines, for portable devices. The
Alliance and General Motors urged NHTSA to complete Phase 2 as soon as
possible, and the Alliance suggested NHTSA combine Phases 1 and 2 into
a single set of NHTSA Distraction Guidelines. The National Safety
Council requested NHTSA reconsider the three-phase approach to the
distraction guidelines and to consider the full body of driver
distraction literature rather than focusing solely on visual-manual
distraction. Specifically, the National Safety Council urged NHTSA to
include cognitive distraction issues in Phase 2 along with the visual-
manual that were the focus of the Phase 1 Distraction Guidelines. CTIA
commented that translating the Phase 1 Distraction Guidelines to
portable devices is infeasible, partly due to the complex ecosystem
surrounding portable devices, and that education and legislative
approaches to the distraction problem should be the government's focus.
The Alliance, Blackberry Limited, General Motors, and Consumers
Union all supported NHTSA's emphasis on paired solutions. The Alliance
reiterated findings from research that quantified the extent to which
consumers are ``connected'' in their daily lives, including while
driving. The Alliance highlighted this research, which was posted to
the Phase 1 Docket, as additional support for pairing or tethering
solutions. The Alliance also highlighted that some of its members were
already working towards pairing solutions, and that the Car
Connectivity Consortium was a formal industry organization working
towards that end. General Motors mentioned its own efforts towards
paired solutions. Blackberry Limited urged NHTSA to consider the ITU-T
draft set of industry-generated recommendations for information and
communications technologies. Consumers Union described its findings on
various existing pairing solutions, and specifically how easy or user-
friendly the pairing process was for drivers. Blackberry Limited
offered several specific suggestions for NHTSA to consider about
pairing solutions and Driver Mode.
The response to Driver Mode solution was mixed, with the Alliance
stating that the only acceptable Driver Mode was the portable device in
the ``off'' setting, and that Driver Mode ``apps'' that drivers must
choose to engage are not realistic solutions. Blackberry Limited,
Consumers Union, and Life Apps provided specific recommendations or
support for Driver Mode implementations. Blackberry Limited had
specific suggestions regarding pairing and Driver Mode, and urged NHTSA
to not recommend less stringent guidelines for Driver Mode, but also
not to include specific technological approaches (i.e., the specific
wireless communication protocol between the portable device and the
vehicle) in the Phase 2 Distraction Guidelines. CTIA also noted the
fact that several driver mode ``apps,'' or applications that otherwise
limit portable device functionality while driving, are currently
available is evidence that industry is working towards solutions to the
distraction problem with portable devices, and therefore NHTSA's
guidelines are unnecessary.
The Alliance supported NHTSA's inclusion of driver-passenger
distinction technology and urged NHTSA to establish a cooperative
research program
[[Page 87670]]
with industry to foster technological development in this area.
Some commenters in the public meeting had specific implementation
suggestions for portable device-use while driving. For example, the
National Safety Council suggested NHTSA require portable devices have
an option to quickly turn the portable device off while driving. Life
Apps highlighted an approach that uses the portable device only, which
does not require hardware components to detect that the driver is using
the device when driving. Vesstech argued for a solution that included
mandatory vocal warnings to be automatically spoken to drivers. It
suggested that the emotional content relayed by the human voice would
be an effective deterrent that would discourage portable device use
while driving. CTIA argued that education, legislation, and technical
innovation are the best ways to address distraction from portable
devices, and listed the ways in which they have been active in each
area.
Agency Response: NHTSA is considering combining Phase 1 and 2
Guidelines, to the extent practicable. As discussed previously, we seek
comment on the combination of the Phase 1 and 2 Guidelines. A statement
of NHTSA's authority to issue voluntary, non-binding guidance is
included in Section V of this notice.
NHTSA provided a detailed explanation and rationale for the focus
on visual-manual distraction in the Phase 1 Guidelines,\68\ which
addresses the National Safety Council's suggestion that NHTSA include
the full-range of distraction and associated research literature,
namely cognitive distraction. NHTSA recognizes the importance of
experimental research findings, such as those using driving simulators,
that show decreased driving performance for distractions of all types.
Both naturalistic driving studies (such as NHTSA's 2013 cell phone
naturalistic driving study \69\) and experimental studies consistently
show that visual-manual distraction contributes to degraded driving
performance and a significantly elevated crash risk. While the full
body of research data is less conclusive with respect to cognitive
distraction, the agency continues to be actively engaged in reviewing
the latest research findings. In May 2015, NHTSA hosted an event called
``Cognitive Distraction: What Were You Thinking?'' \70\ that brought
members of the international research community and safety advocates
together to discuss what cognitive distraction is, how to measure it,
and what to do about it. NHTSA is also currently conducting a
significant amount of research related to auditory-vocal (i.e., voice-
based) system interfaces, as well as a study to explore ways of
measuring internal cognitive distraction (e.g., mind wandering) while
driving.

---------------------------------------------------------------------------
NHTSA has reviewed each of the detailed recommendations from the
various commenters on both pairing and driver mode. Some of those
recommendations are consistent with NHTSA's goal of remaining neutral
regarding specific technological approaches to pairing and to Driver
Mode activation, and therefore are reflected in these proposed Phase 2
Guidelines. At NHTSA's public meeting, participants on the Driver-
Passenger Distinction panel presented different technological
approaches to identifying which vehicle occupant is using a portable
device. Most approaches use a combination of hardware and software
installed in the vehicle and on the portable device to determine
whether the device user is a driver or passenger.
One approach involved a piece of hardware that creates zones within
a vehicle by emitting signals. The driver's seating position would have
a different signal that could be identified by software and/or hardware
on a portable device. Identifying the driver's position with this
method would potentially allow the device to activate the driver mode
only for the driver while he or she is driving. This signal could vary
depending on the transmission state.
Another driver-passenger distinction technology uses capacitive
sensors within the seats that allow the vehicle to detect where
portable devices are being used within a vehicle. These sensors are
able to determine if each occupant is holding and using a portable
device by utilizing the conductivity of the human body. By detecting if
a driver is using a portable device, the vehicle can tell the portable
device to activate the driver mode. Driver Mode can be activated
depending on the state of the vehicle's transmission (i.e., park vs.
drive).
Finally, a device-only solution uses an authentication task
approach where a device automatically goes into a limited use state
(e.g., Driver Mode) at a speed threshold, and a quick, but challenging
task is required to re-enable full functionality on the device. These
authentication tasks are designed to be quick and easy for non-drivers,
but nearly impossible to complete successfully within the short time
limit for drivers.
NHTSA recognizes that there may be other concepts to achieve
driver-passenger distinction that were not presented in the Public
Meeting, but those presented provide an example of how this capability
can be achieved technologically. Accordingly, NHTSA continues to
monitor the development and progress of driver-passenger distinction
technologies, and seeks input on how to foster the refinement of that
technology to enhance reliable and automatic Driver Mode solutions for
unpaired portable devices. For example, the Alliance recommended
establishing a cooperative research program. The agency seeks comments
from all stakeholders on what specific research needs remain to
progress driver-passenger distinction technology to full maturity.

Meeting are available for download in the Phase 2 docket,\71\ along

III. Distraction Guidelines for Portable and Aftermarket Devices
A. Scope
1. Devices/Device Interfaces
The proposed Phase 2 Guidelines would apply to the visual-manual
interfaces of portable and aftermarket devices that may be used by a
driver. A ``portable device'' is defined as a device that can
reasonably be expected to be brought into a vehicle on a trip-by-trip
basis and used in the vehicle by a driver while driving, that is
electrically powered, and that has one or more of the following
capabilities:
Allows user interaction.
Enters, sends, and/or receives information.
Displays information in a visual and/or auditory manner,
or
Displays graphical, photographic, and/or video images.
The agency has tentatively concluded that this definition sets out
the appropriate scope for the types of device
[[Page 87671]]
interfaces that should be covered by the Phase 2 Guidelines, i.e., the
interfaces of portable electronic devices that are likely to be used by
drivers when driving. Examples of portable devices covered by the
proposed Phase 2 Guidelines are smartphones, tablets, and navigation
devices. The recommendations to manufacturers in these guidelines are
intended to focus on devices used by drivers while driving. NHTSA seeks
comment on whether clarification/revisions to the provisions in this
guidance document are necessary to ensure that passengers/non-drivers
are not inadvertently impacted by this guidance document. In other
words, NHTSA seeks to ensure that passengers (including front
passengers) are able to use their devices and applications without
disruption.
Additionally, this definition would include some of the new
portable technology that is beginning to appear, such as wearable
technology (electronic devices with interfaces that are worn on and
move with the body) and certain non-OE, head-up displays (HUDs).\72\
Wearable technology includes wristwatch computers and optical head-
mounted displays (OHMD). Although OHMD and HUD interfaces are
classified as portable or aftermarket devices and would therefore be
covered by the Phase 2 Guidelines, the agency notes that there are
issues with applying the Phase 1 glance-based metrics to measure the
level of visual distraction associated with the use of these devices.
The most significant issue with applying Phase 1 acceptance tests to
OHMD and HUD is that the performance criteria for measuring distraction
is eyes-off-road time and the information from these technologies is
displayed either directly in front of the driver's eyes (OHMD) or on
the windshield in front of the driver (HUD). While the driver may
appear to be looking toward the forward roadway, the driver's eyes
would actually be focused at a different focal distance that
corresponds to the displayed OHMD/HUD information. This means that in
testing it may not be possible to reliably discern whether the driver's
eyes are focused on the roadway or the information displayed on the
OHMD/HUD, which confounds the ability to evaluate eye glance behavior
to the task acceptance criteria. The agency is concerned that although
these devices might tend to keep the eyes oriented toward the forward
roadway, the presentation of information in front of the driver may
still result in visual distraction causing the eyes to be focused on
the displayed information rather than on the road (e.g., visual
accommodation changes to view the presented information could result in
the driver's view of the forward roadway being out of focus).
Accordingly, the agency has begun research on these devices to
determine whether their use impacts vehicle safety and, if so, what
visual attention metrics might be used to explain the effects.
---------------------------------------------------------------------------
\72\ HUDs for motor vehicles project information onto the
windshield in front of the driver.
---------------------------------------------------------------------------
Finally, NHTSA recognizes that many of these new portable devices
are released as pre-production versions, thereby allowing the market to
update, refine, and shape the maturation of the technology. NHTSA seeks
comment on portable device product cycles along with software updating
processes to better understand the evolving stakeholder landscape.
For the purposes of this Phase 2 proposal, an ``aftermarket
device'' is defined as a device designed to be or reasonably expected
to be installed or integrated into a vehicle after the vehicle is
manufactured, is electrically powered, and has one or more of the
following capabilities:
Allows user interaction.
Enters, sends, and/or receives information.
Displays information in a visual and/or auditory manner,
or
Displays graphical images, photographic images, and/or
video.
An example of an aftermarket device would be a non-OE head unit,
such as in-dash car audio/video systems or in-dash navigation systems.
NHTSA requests comments on its proposed definitions in the proposed
Phase 2 Guidelines.
The proposed Phase 2 Guidelines exclude several devices/device
interfaces, including the auditory-vocal portions of a portable or
aftermarket device interface,\73\ device or device functions specified
by law or government regulation, or devices manufactured primarily for
emergency response vehicles. These exclusions mirror those listed in
the Phase 1 Guidelines for OE in-vehicle interfaces. However, in
contrast to the Phase 1 Guidelines, NHTSA believes that the proposed
Phase 2 Guidelines do not necessarily need to be restricted by vehicle
weight and would apply to the interfaces of portable and aftermarket
devices used in medium and heavy vehicles (i.e., those with a gross
vehicle weight rating (GVWR) over 10,000 pounds). The Phase 1
Guidelines excluded OE in-vehicle interfaces in these vehicles because
they are different than the interfaces in light vehicles (GVWR of
10,000 pounds or less) and additional research would be needed to
develop guidelines for medium and heavy vehicles. In contrast, NHTSA
does not believe that the same types of differences, if any, exist
between portable and aftermarket devices used in light vehicles versus
those used in heavy vehicles, and, therefore such an exclusion is not
warranted for the Phase 2 Guidelines.
---------------------------------------------------------------------------
\73\ NHTSA recognizes that current auditory-vocal interfaces are
multi-modal and include a combination of auditory-vocal and visual-
manual interactions. All visual-manual interactions are subject to
Phases 1 and 2 of the Distraction Guidelines.
---------------------------------------------------------------------------
The agency also seeks comment on device interfaces that should or
should not be covered by the proposed Phase 2 Guidelines.
2. Tasks
The proposed Phase 2 Guidelines would be applicable to the same
types of visual-manual secondary tasks covered by the Phase 1
Guidelines, including all non-driving-related tasks and some driving-
related tasks (as noted earlier), specifically those that are neither
related to the safe operation and control of the vehicle nor involve
the use of a system required by law. Table 1 of the updated Phase 1
Guidelines \74\ published on September 14, 2014, contains a non-
exhaustive list of the types of non-driving-related tasks to which the
Guidelines would be applicable, including various communications,
entertainment, and information tasks. This table is repeated in Table 7
below.

------------------------------------------------------------------------
Like the Phase 1 Guidelines, the Phase 2 Guidelines would not apply
to tasks performed by the driver as part of the safe operation and
control of the vehicle, including any task related to the proper use of
a driver safety warning system. Although the agency did not define the
term driver safety warning system in the Phase 1 Guidelines, the agency
is including a definition in the proposed Phase 2 Guidelines (that also
shall apply to Phase 1) because of the wide variety of portable and
aftermarket device applications that exist and the agency's concern
that applications with a questionable link to safety might be labeled
as driver safety warning systems. Accordingly, the proposed Phase 2
Guidelines define ``driver safety warning system'' as ``a system or
application that is intended to assist the driver in the avoidance or
mitigation of crashes.'' An example of a system that would fall within
this definition is a portable device application that uses the device's
features (e.g., GPS, accelerometer, or camera) to alert drivers of lane
departures or potential collisions.
Finally, the Phase 2 Guidelines apply to tasks that are clearly
bounded by start and end states as is discussed in the Phase 1
Guidelines (see section IV.B.9 on p. 24884). Displays that continuously
report a system state like speed or fuel economy status are unbounded
and are therefore not subject to the Phase 1 or 2 Guidelines.
B. Overview of the Phase 2 Guidelines
In order to address the vehicle safety problem posed by driver
distraction due to aftermarket and portable device usage, NHTSA
tentatively recommends the following in its Phase 2 Guidelines:
Portable device manufacturers incorporate pairing
capabilities and Driver Mode functions into their devices to reduce
driver distraction.
OEMs incorporate pairing capabilities into the design of
their vehicles
Manufacturers of aftermarket devices meet the requirements
as specified for OE interfaces in Phase 1.\75\
---------------------------------------------------------------------------
\75\ While the recommendation is that aftermarket devices meet
the Phase 1 Guidelines, this recommendation will be made in the
Phase 2 document. Therefore, aftermarket manufacturers would look to
the Phase 2 guidelines for recommendations.
---------------------------------------------------------------------------
Figure 1 depicts how the Phase 2 Guidelines apply to both portable
and aftermarket devices, including pairing and Driver Mode
configurations.
[[Page 87673]]
[GRAPHIC] [TIFF OMITTED] TN05DE16.002
NHTSA recommends pairing a portable device with the in-vehicle
system (i.e., OE or installed aftermarket systems) to minimize the
potential distraction associated with operating a visual-manual
interface on a portable device. Vehicle manufacturers and the portable
device industry are already working together to incorporate pairing
between devices and vehicles, and the agency hopes that the Phase 2
Guidelines will accelerate those efforts.\76\ Pairing the device to the
vehicle would allow the driver to use the built-in displays and
controls. Assuming that the vehicle conforms to the Phase 1 Guidelines,
pairing would ensure that the visual-manual secondary tasks performed
by the driver while driving meet the time-based, eye-glance task
acceptance criteria specified in the Phase 1 Guidelines that is
intended to mitigate the risk of distracted driving. Pairing would also
ensure that certain activities that would inherently interfere with the
driver's ability to safely control the vehicle would be locked out
while driving (i.e., the ``per se lock outs'' referred to in the Phase
1 Guidelines and the proposed Phase 2 Guidelines).

---------------------------------------------------------------------------
Although NHTSA recommends that pairing a portable device with the
in-vehicle interface is the best way to mitigate the distraction
associated with operating a visual-manual portable device interface,
the agency acknowledges that there will be situations when pairing does
not occur, either because the in-vehicle system and/or portable device
does not possess the capability for pairing or because the driver
chooses not to pair with the in-vehicle system. In order to mitigate
the additional distraction associated with the use of an unpaired
portable device, the agency recommends that portable devices include a
Driver Mode that, when activated, will present an interface that
conforms with the Phase 1 Guidelines recommendations for electronic
devices used by the driver while driving. In particular, when a
portable device is in Driver Mode, the device should lock out tasks
that are among the Phase 1 Guidelines per se lock outs or do not meet
Phase 1 task acceptance criteria.
NHTSA seeks comment on this approach and whether additional per se
lock outs are appropriate for portable and aftermarket devices, whether
paired with the in-vehicle system or in Driver Mode.
NHTSA acknowledges that some devices, such as standalone portable
navigation devices, are designed for, and exist primarily for use in a
single context (e.g. navigation in a motor vehicle). These devices are
useful because they package both the hardware and a user interface in
one compact portable unit. For such a device designed primarily for use
while driving, pairing the device with the vehicle would not provide
any benefit since its native interface should meet the Driver Mode
recommendations and pairing is not required. For this reason, portable
navigation devices that do not have pairing capability would not be
expected to have a separate Driver Mode. NHTSA requests comments on
whether the assumptions for this recommendation are reasonable and
appropriate.
C. Pairing
1. Pairing Recommendations
The proposed Phase 2 Guidelines recommend that vehicle
manufacturers and portable device manufacturers should provide the
necessary mechanisms to easily enable pairing
[[Page 87674]]
between the portable device and the vehicle/in-vehicle system.\77\ In
order to reduce the potential for distraction associated with pairing
while also encouraging drivers to pair their devices, pairing should be
an easy-to-understand task that allows the driver to set up the
portable device to communicate with the in-vehicle system in the fewest
number of steps possible, even automatically if feasible. If a portable
device and vehicle pair easily, it is less likely that a user will
become discouraged and not attempt to pair a device with a vehicle.
NHTSA encourages all entities involved with the engineering and design
of pairing technologies to jointly develop compatible and efficient
processes that focus on improving the usability of connecting a
portable device with the in-vehicle system. The proposed Guidelines
further recommend that any required visual-manual interactions
necessary to pair the device should be disabled while driving in order
to avoid potential driver distraction. The agency encourages automatic
pairing between the portable device and in-vehicle system during and
after the initial setup.
---------------------------------------------------------------------------
\77\ For purposes of this discussion, ``in-vehicle system''
includes both OE and aftermarket headunits installed in a motor
vehicle.
---------------------------------------------------------------------------
In order to ensure that a paired portable device's functions are
operated through the in-vehicle interface, which is intended and
designed specifically for the driving environment, the proposed Phase 2
Guidelines recommend that the visual interface of the portable device
be locked out when the portable device is paired to the in-vehicle
system, with the exception of access to emergency services and
emergency notifications. All non-emergency functions and applications
of the portable device should be operable exclusively through the in-
vehicle system's interface. A paired system with a compelling user
experience and features should discourage the need for the driver to
access or interact with the portable device while driving. NHTSA seeks
comment on displaying and operating all non-emergency paired device
functions through the in-vehicle interface and whether doing so creates
unintended consequences. NHTSA also seeks comment on how best to
accommodate passenger use of a paired portable device.
2. Privacy and Data Sharing for Paired Devices
The primary purpose of this document is to address driver
distraction and vehicle safety. However, NHTSA acknowledges that the
pairing recommendations may touch on potential privacy concerns
regarding the possibility of data transfer, sharing, and storage
between the vehicle, device, and off-board systems. The proposed
Guidelines do not recommend any particular method of pairing or specify
how automakers and the portable and aftermarket device industries
should address how information is shared and used. The agency
encourages industry to consider how privacy risks can be minimized as
part of the development and improvement of pairing systems.
Industry groups have begun to address the issue of privacy as the
Alliance of Automobile Manufacturers and Global Automakers published a
set of principles on November 12, 2014.\78\
---------------------------------------------------------------------------

Global Automakers (2014). Consumer Privacy Protection Principles:

from http://www.autoalliance.org/index.cfm?objectid=CC629950-6A96-11E4-866D000C296BA163 (last accessed on 10/4/16).
---------------------------------------------------------------------------
In light of these potential issues, NHTSA seeks comment on how
information is shared between the vehicle, device, and off-board
systems when devices are paired with the vehicle, how the type of
information that is shared may change in the future, how this
information sharing effects privacy, and what role the Guidelines can
and should play in addressing these privacy issues.
3. Cybersecurity for Paired Devices
Designing portable devices so that they can be paired with motor
vehicles must be accompanied by appropriate cybersecurity measures.
Unless such care is taken, adding another Internet-connected device to
a vehicle's electronics system can introduce additional cybersecurity
vulnerabilities into a vehicle's computer systems.
Safeguarding the traveling public through a combination of measures
requiring and/or encouraging the incorporation of safety features and
systems in motor vehicles and motor vehicle equipment as well as
measures to protect the performance of those features and systems is
part of NHTSA's core mission. Equally important is identifying motor
vehicles or items of motor vehicle equipment that create an
unreasonable risk of accidents occurring or unreasonable risk of death
or injury occurring in an accident because of deficiencies in design,
construction, or performance and requiring their recall and remedy.
These Guidelines do not suggest or recommend particular methods for
creating and maintaining an effective level of cybersecurity in motor
vehicles or in portable or aftermarket devices. NHTSA expects that
OEMs, portable device manufacturers, and aftermarket manufacturers to
be proactive and take the steps necessary to protect against present
and future motor vehicle cybersecurity threats. We seek comment on the
continuing steps that must be taken to ensure that pairing does not
adversely affect vehicle cybersecurity.
D. Driver Mode
Ideally, a Driver Mode would not be necessary since NHTSA believes
those functions related to the driving task should occur when the
device is paired with an in-vehicle system that conforms with the Phase
1 Guidelines. However, our data confirms what everyday observation
indicates: Many drivers routinely use their portable device(s) while
driving. The agency believes that over time as pairing becomes easier,
increased device pairing may help reduce this behavior, but is unlikely
to eliminate it, because not all vehicles will have been designed to
allow pairing and drivers may not choose to pair their devices. The
agency, therefore, believes it is necessary to propose guidelines that
attempt to reduce the risk associated with using an unpaired portable
device while driving. The agency believes that the proposed Driver Mode
outlined below, which suggests that the device's interface follow the
Phase 1 principles to the extent possible, is the best way to minimize
the distraction posed by these devices.
1. Driver Mode Recommendations
Driver Mode is a simplified interface for unpaired devices that
conforms to the Phase 1 Guidelines when being used by a person who is
driving. When in Driver Mode, the portable device should lock out any
visual-manual secondary tasks that do not meet the Phase 1 Guidelines,
either because they are per se lockouts or because they do not meet the
eye-glance-based task acceptance criteria using a modified version of
the Phase 1 task acceptance testing procedures described in Section V
of the Phase 2 Guidelines.
The Phase 1 Guidelines specify two different test options for
measuring the impact of performing a task on driving safety and
acceptance criteria for assessing whether a task interferes enough with
driver attention to be unsuitable for performance while driving. Either
test may be run to assess conformance with the guidelines. Both of
these test methods focus on the amount of visual attention necessary to
complete a task because existing research on visual-manual distraction
establishes a link between visual
[[Page 87675]]
attention (eyes off the road) and crash risk.
The first recommended test method measures the amount of time that
the driver's eyes are drawn away from the roadway during the
performance of the task. The proposed Phase 2 Guidelines, like the
Phase 1 Guidelines, recommend that devices be designed so that tasks
can be completed by the driver while driving with glances away from the
roadway of 2 seconds or less and a cumulative time spent glancing away
from the roadway of 12 seconds or less. NHTSA anticipates that
stakeholders (e.g., OS developers, portable device developers, and
application developers) will work together to ensure that applications
and features on portable devices intended for use while driving meet
the Phase 2 Guidelines. NHTSA requests comments on how this industry
process will develop and function.
The second test method uses a visual occlusion technique, and both
the Phase 1 and proposed Phase 2 Guidelines recommend that, when tested
with this method, devices be designed so that tasks can be completed in
a series of 1.5-second glances with a cumulative time of not more than
12 seconds.\79\ Both of these tests are part of the Phase 1 NHTSA
Guidelines and the Alliance of Automobile Manufacturers (Alliance)
guidelines.
---------------------------------------------------------------------------
\79\ As explained in detail in the Phase 1 Guidelines notices,
the 1.5-shutter open time periods used in the occlusion method
correspond to 2 second off-road glances.
---------------------------------------------------------------------------
Detailed discussions of how these thresholds were developed are
contained in the proposed Phase 1 Guidelines notice \80\ and the final
Phase 1 Guidelines notice.\81\ In summary, glances away from the
forward road scene greater than 2 seconds at a time are associated with
an increased risk of a crash or near crash. The total eyes off road
time criterion is based on the principle that a visual-manual secondary
task performed while driving should not exceed that associated with a
baseline reference task (in this case, the manual tuning of a radio).
NHTSA selected radio tuning as the reference task \82\ and determined
that the 85th percentile total eyes off road time (TEORT) associated
with radio tuning is 12 seconds. Recent testing conducted by the agency
to assess the proposed acceptance criteria for both the simulator and
occlusion procedures supports the use of 2-second individual glance
duration criterion and a12-second TEORT criterion (i.e., a ``2/12
Rule'').\83\

---------------------------------------------------------------------------
NHTSA has tentatively concluded that because the crash risk
associated with distraction caused by vehicle OE interfaces and
portable devices is borne out of similar visual-manual interaction
between the driver and the device, the Phase 2 Guidelines should apply
the Phase 1 Guidelines to the proposed Driver Mode. In other words,
because a driver would be diverting his or her attention away from the
road to an area within reach and view of the driver compartment, a
recommendation for a portable device in Driver Mode should be similar
to that of in-vehicle systems.
In addition to the recommendations regarding per se lock outs and
the task acceptance criteria, the proposed Phase 2 Guidelines recommend
that when in Driver Mode, portable device interfaces conform to the
following Phase 1 Guidelines recommendations:
No Obstruction of View
Easy to See and Reach
Sound Level
Single-Handed Operation
Interruptibility
Device Response Time
Disablement
Distinguish Tasks of Functions not intended for use while
driving
Device Status
Due to the differences between integrated OE interfaces and
portable devices, the proposed Phase 2 Guidelines do not include the
Phase 1 recommendations related to maximum downward viewing angle,
lateral position of visual displays, and minimum size of displayed text
information. These recommendations relate to the placement of the
interface or the size of the interface text given that placement.
Because the placement of a portable device in a vehicle is determined
by the owner or driver of the vehicle rather than the device
manufacturer or software designer, the agency has tentatively concluded
that, as it cannot know for certain where, how, or if the device will
be mounted, these recommendations are not appropriate for portable
devices.
Despite this fact, the agency still believes it is necessary to
propose a repeatable test that would allow the agency to determine what
devices conform with the proposed Driver Mode. Such a test, even if it
does not reflect how all drivers use portable devices in all
circumstances, would, nevertheless, provide the agency with a benchmark
to measure conformance across a wide variety of different devices. The
agency proposes that manufacturers test unpaired portable devices,
including those in Driver Mode, in a location within a vehicle that, to
the greatest extent possible, conforms to the recommendations
enumerated in Phase 1 (i.e. no obstruction of view, easy to see and
reach) and do not result in the portable device interfering with airbag
deployment zones or safe operation of the vehicle controls. The agency
believes that this is a repeatable means to address Driver Mode
conformance, which may be representative of how the device may be
mounted in the vehicle by a driver. The agency acknowledges that some
drivers may not mount their portable device and, instead use it while
holding it in their hand. However, the agency does not believe it is
possible or desirable to create a repeatable test based on in-hand use.
The agency requests comments on differences between vehicle OE
interfaces and portable devices. Specifically, NHTSA would like to know
what, if any testing methods, stakeholders currently use (or suggest
using) to address the varying placements of a portable device inside an
automobile.
The Phase 1 Guidelines per se lock outs include activities that are
discouraged by public policy and, in some instances, prohibited by
Federal regulation or State law (e.g., entering or displaying text
messages), and activities identified in industry driver distraction
guidelines that NHTSA agrees are likely to distract drivers
significantly (e.g., automatically scrolling text). The per se lock
outs also address activities that are extremely likely to be
distracting due to their very purpose of attracting visual attention,
but whose obvious potential for distraction cannot be measured using a
task timing system because the activity could continue indefinitely
(e.g., displaying video or certain images). Below is a detailed
description of the per se lock outs taken from the Phase 1 Guidelines:

---------------------------------------------------------------------------
[[Page 87676]]
Device functions and tasks not intended to be used by a
driver while driving.
Manual Text Entry. Manual text entry by the driver for the
purpose of text-based messaging, other communication, or internet
browsing.
Displaying Video. Displaying (or permitting the display
of) video including, but not limited to, video-based entertainment and
video-based communications including video phoning and
videoconferencing.
Exceptions: \85\
---------------------------------------------------------------------------
\85\ Certain exceptions to the video per se lock out are not
listed here because it is unlikely that a portable or aftermarket
device's interface would include that type of functionality (e.g.,
rearview images used to aid the driver performing a maneuver in
which the vehicle's transmission is in reverse gear). However, all
of the display of video per se lock out exceptions listed in the
Phase 1 Guidelines would also be applicable to portable and
aftermarket devices.
---------------------------------------------------------------------------
Map displays. The visual presentation of dynamic map and/
or location information in a two-dimensional format, with or without
perspective, for the purpose of providing navigational information or
driving directions when requested by the driver (assuming the
presentation of this information conforms to all other recommendations
of these Guidelines). However, the display of informational detail not
critical to navigation, such as photorealistic images, satellite
images, or three-dimensional images is not recommended.
Displaying Images. Displaying (or permitting the display
of) non-video graphical or photographic images.
Exceptions:
Displaying driving-related images including maps (assuming
the presentation of this information conforms to all other
recommendations of these Guidelines). However, the display of map
informational detail not critical to navigation, such as photorealistic
images, satellite images, or three-dimensional images is not
recommended.
Static graphical and photographic images displayed for the
purpose of aiding a driver to efficiently make a selection in the
context of a non-driving-related task (e.g., music) is acceptable if
the image automatically extinguishes from the display upon completion
of the task. If appropriate, these images may be presented along with
short text descriptions that conform to these Guidelines.
Internationally standardized symbols and icons, as well as
TrademarkTM and Registered[supreg] symbols, are not
considered static graphical or photographic images.
Automatically Scrolling Text. The display of scrolling
(either horizontally or vertically) text that is moving at a pace not
controlled by the driver.
Displaying Text to Be Read. The visual presentation of the
following types of non-driving-related task textual information:
Books
Periodical publications (including newspapers, magazines,
articles)
Web page content
Social media content
Text-based advertising and marketing
Text-based messages (see definition) and correspondence
Exception:
The visual presentation of limited amounts of other types
of text during a testable task is acceptable. The maximum amount of
text that should be visually presented during a single testable task is
determined by the eye-glance-based acceptance tests.
The agency requests comment on the applicability of the Phase 1 per
se lock outs to portable devices. Are additional exceptions needed for
certain portable device tasks? Are there additional portable device
tasks that should be included in the per se lock outs if the device has
a Phase 1 Guidelines-conforming Driver Mode interface?
2. Driver Mode Activation
The Phase 2 Guidelines' proposed recommendations regarding the
activation of the Driver Mode would differ significantly from the Phase
1 Guideline's recommendations in terms of when OE in-vehicle devices
should lock out certain tasks and meet certain other device
recommendations.
In particular, the Phase 1 Guidelines recommend that OE in-vehicle
devices should lock out certain tasks from performance by the driver
while ``driving.'' ``Driving'' is defined as whenever a vehicle's means
of propulsion is activated unless the vehicle's transmission is in the
``Park'' position or, for manual transmission vehicles, the vehicle's
transmission is in the ``neutral'' position, the parking brake is
engaged, and the vehicle's speed is less than 5 mph.
This definition was based on definitions used in various statutes,
regulations, and Executive Orders related to distracted driving,\86\
which defined driving as operating a vehicle on an active roadway with
the motor running, including while temporarily stationary because of
traffic, traffic control devices, etc. The agency was also concerned
that limiting ``driving'' to when a vehicle is traveling above a
certain speed could result in drivers performing distracting tasks at
low speeds, creating an increased risk of a crash at signal- or sign-
controlled intersections and in traffic. Accordingly, by using existing
definitions as a foundation, the agency developed a definition that is
based on information known to, or able to be detected by vehicle
systems: Transmission position, vehicle speed, and the status of the
parking brake.

13513, ``Federal Leadership on Reducing Text Messaging While
Driving,'' October 1, 2009; MAP-21 Public Law 112-114, 126 Stat. 405
(July 6, 2012).
---------------------------------------------------------------------------
In analyzing how to apply the Phase 1 Guidelines to portable and
aftermarket devices, the agency has determined activation of Driver
Mode is dependent upon the technologies and features present, as well
as the level of communication between a portable/aftermarket device and
a vehicle. Based on these considerations, the agency has developed two
alternative methods for activating Driver Mode.
The first option, and the one encouraged by the agency, is
automatic activation, meaning that Driver Mode automatically engages
within a reasonable period of time when the portable device by itself
or in conjunction with the vehicle distinguishes that it is being used
by a driver while driving. If desired, the user would have the ability
to deactivate or opt-out of automatic engagement of Driver Mode. Like
the ``driving'' condition described in the Phase 1 Guidelines, this
definition is based on information (e.g., vehicle speed) that can be
determined by the portable device if it has the appropriate sensors
like GPS to measure the speed of the motor vehicle, or if the
information is transmitted from the vehicle to the portable device. The
Phase 1 definition of driving may be suitable if the automatic
distinction technology can also access speed or transmission state
information directly from the vehicle. Examples of automatic
distinction technologies that had direct connection to the vehicle, and
therefore could have access to vehicle speed or transmission state,
were presented at NHTSA's Phase 2 Public Meeting.\87\ The agency
requests comment on whether the final guidelines should include
specific triggering factors or a specific timeframe for Driver Mode to
automatically
[[Page 87677]]
activate, such as the vehicle speed (e.g., a speed that can reasonably
be attributed to a motor vehicle as opposed to non-motorized
transportation) at which an automatic activation would engage, as well
as other potential triggering factors. Additionally, NHTSA requests
comment on the 5 mph speed threshold applicable to the definition of
``driving'' for vehicles without a ``Park'' position (e.g. manual
transmission vehicles).
---------------------------------------------------------------------------
\87\ Docket No. NHTSA-2013-0137, ``Driver Distraction Guidelines
(Phase 2) for Portable and After-Market Devices Public Meeting
Agenda and Presentations'' ID: NHTSA-2013-0137-0004. Available at
http://www.regulations.gov/#!docketDetail;D=NHTSA-2013-0137 (last
accessed on 10/4/16).
---------------------------------------------------------------------------
The agency recognizes that automatic activation technologies are
still in the process of being refined, and, without the ability to
reliably detect whether the device user is the driver or a passenger,
may be overly annoying to device users. Accordingly, the agency is
proposing a second option, voluntary activation, meaning that the
Driver Mode is activated in a simple manner by the user. In other
words, under this option, Driver Mode is manually activated by the
driver rather than automatically. The agency expects technologies that
support automatic Driver Mode activation to be implemented as soon as
practicable. In order to provide flexibility, NHTSA has not included
any additional specific recommendations on how activation of Driver
Mode should be designed. The agency requests comment on whether
additional specification should be included in the final guidelines.
Recognizing that some drivers may choose not to activate Driver
Mode, and accordingly, not reduce the distraction potential of the
portable device, the agency foresees driver-initiated activation being
a temporary option in the Phase 2 Guidelines until driver-passenger
distinction technology is more developed and widely available. The
agency expects such technology to be implemented as soon as
practicable. The agency recognizes the inherent limitations of a
driver-activated Driver Mode and seeks comment on alternative
approaches to Driver Mode activation as a temporary option until
driver-passenger distinction technology is implemented.
E. Aftermarket Devices
The US DOT's Blueprint for ending Distracted Driving specified that
aftermarket electronic devices would be addressed in NHTSA's Phase 2
Guidelines. In line with the Blueprint, the Phase 2 Guidelines propose
to make recommendations for aftermarket devices. Tentatively, the
agency concludes that recommendations applicable to OE manufacturers in
the Phase 1 Guidelines shall be recommendations to aftermarket
electronic device manufacturers.
Aftermarket devices include communication, entertainment, or
navigation devices that are designed to be or would be reasonably
expected to be installed or integrated after the vehicle is
manufactured, are often incorporated into existing OE slots in the
dashboard or are permanently affixed to the top surface of the
dashboard. Examples of aftermarket devices include in-dash car stereos/
receivers and in-dash navigation devices. While aftermarket devices are
addressed in the same guideline document as portable devices, there are
notable differences between portable and aftermarket devices. As
aftermarket devices are typically hardwired into a vehicle, they are
not likely to be moved in and out of a vehicle like portable devices.
Additionally, because there is a physical link between an aftermarket
device and the vehicle, there is no need for any pairing
recommendation, as the vehicle and aftermarket device are linked by
virtue of installation.
With regard to placement within the vehicle, the installation
location of an aftermarket device is likely to be either on the
dashboard or in a vacated spot in the dash previously occupied by an OE
interface. NHTSA has tentatively concluded that because the crash risk
associated with distraction caused by OE interfaces and aftermarket
devices is borne out of similar visual-manual interaction from the same
location in a vehicle, the Phase 2 Guidelines should apply the Phase 1
guidelines to aftermarket devices. In many cases, aftermarket devices
serve as replacement devices for vehicle OE systems, replacing the
function of OE units while occupying the same location within a
vehicle. NHTSA is seeking comment on this approach.
IV. Expected Effects of the Phase 2 Guidelines
NHTSA's overall expectation for the Phase 2 Distraction Guidelines
is to provide a safety framework for developers of portable and
aftermarket electronic devices and applications to use when developing
their systems that will reduce driver distraction through two specific
technological means. First, NHTSA envisions easy pairing solutions for
users of portable devices in their vehicles that will result in
accelerated growth and acceptance of pairing, leading to pairing
implementations throughout entire vehicle lineups and trim levels.
Pairing solutions should become seamless, thereby fostering highly
efficient interactions between the drivers, portable devices, and in-
vehicle electronics systems. Second, NHTSA expects these guidelines
will encourage the further growth and innovation of automatic driver
distinction technologies that will enable more practical and pervasive
Driver Mode implementations for portable devices in unpaired scenarios.
The development of automatic driver distinction technologies and
consequently Driver Mode interfaces should result in reduced
distraction when used by drivers while driving. Again, the agency's
goal is that information available to the driver inside the vehicle
will not cause an unsafe level of distraction to the driver (either by
functions being locked out or conforming to the applicable Phase 1
Guidelines' 2/12 performance criteria).
In addition, NHTSA expects that through these guidelines,
automotive OEMs, application developers, portable and aftermarket
device manufacturers, operating system providers, wireless carriers,
and all involved stakeholders will jointly work together with the
primary goal of reducing fatalities, injuries, and crashes attributable
to the use of portable and aftermarket devices by drivers. NHTSA
expects that the proposed guidelines will serve as a framework for
stakeholders to continue developing a variety of technologies and
designs that reduce visual-manual distraction while driving.
Ultimately, these proposed Guidelines will raise awareness of driver
distraction and elevate vehicle safety to a top priority within the
product development processes for these wide-ranging organizations.
A. Estimated Time for Conformance
NHTSA wants to make it absolutely clear that since its Driver
Distraction Guidelines are voluntary and non-binding, they do not have
a ``lead time'' in the same way that a FMVSS or other regulation has a
lead time. Portable and aftermarket device manufacturers, application
developers, and vehicle manufacturers are not required to meet the
NHTSA Guidelines.
NHTSA stated that it anticipated vehicle manufacturers would
incorporate Phase 1 conformance into their normally scheduled
production cycles, and therefore NHTSA anticipates seeing production
vehicles that conform to Phase 1 Guidelines no sooner than three years
from the publication of Phase 1. NHTSA recognizes that the production
cycles for portable devices are dramatically shorter than for vehicles;
therefore NHTSA seeks comment on reasonable conformance testing timing
for Phase 2. We believe 16 months is appropriate given the speed at
which technology changes and the time needed to benchmark product
against
[[Page 87678]]
the final guidelines. We understand that a portable device's ability to
pair with a vehicle inherently requires some coordination with vehicle
OEMs. We request comment on the appropriateness of this timeframe.
The agency also notes that the Guidelines are just one of many
efforts by both government and industry to address the distracted
driving problem. The NHTSA Distraction Plan \88\ describes the Agency's
comprehensive approach to the distraction problem. NHTSA has approached
the driver distraction problem from multiple fronts, from a better
understanding of the issue of distraction by improving the quality of
data on the incidence, prevalence, and crash risk from distraction, to
public service messages (e.g., ``One text or call could wreck it
all''), to working with states on enforcement programs and improving
laws, to producing the Distraction Guidelines. Industry has also worked
hard to promote anti-driver-distraction awareness and message
campaigns, as well as working toward guidance and tools for less
distracting devices and built-in user interfaces. NHTSA's Guidelines
are an important complementary effort against driver distraction.

---------------------------------------------------------------------------
B. NHTSA Monitoring of Portable and Aftermarket Device Conformance With
the Guidelines
NHTSA's Office of Vehicle Safety Research intends to perform future
monitoring to assess conformance to our Driver Distraction Guidelines.
Whereas the details of this monitoring have yet to be determined, we
plan to test actual production vehicles, and production portable and
aftermarket devices. Vehicles, portable and aftermarket devices, and
applications will be selected for such monitoring so that they
represent a representative portion of makes and models available for
public consumption. NHTSA envisions that these test results would be
made available to the public.
V. Authority To Issue the Phase 2 Guidelines
The agency's authority to issue the voluntary, non-binding \89\
Phase 2 Guidelines is clear under both the Highway Safety Act and the
Vehicle Safety Act.\90\ NHTSA's statutory mandate is to reduce traffic
accidents and deaths and injuries resulting from traffic accidents.\91\
To carry out this mandate, NHTSA is authorized to conduct and act on
both behavioral safety and vehicle safety research. Congress directed
the Secretary of Transportation, through amendments to the Highway
Safety Act, to assist and cooperate with private industry (among
others) to increase highway safety.\92\ Additionally, the Vehicle
Safety Act states NHTSA ``shall conduct research, development, and
testing on any area or aspect of motor vehicle safety necessary to
carry out this chapter.'' \93\ More specifically, NHTSA ``shall . . .
conduct motor vehicle safety research, development, and testing
programs and activities, including activities related to new and
emerging technologies that impact or may impact motor vehicle safety.''
\94\
---------------------------------------------------------------------------
\89\ See Fixing America's Surface Transportation Act, Public Law
114-94, 24406 (2015) (``No guidelines issued by the Secretary with
respect to motor vehicle safety shall confer any rights on any
person, State, or locality, nor shall operate to bind the Secretary
or any person to the approach recommended in such guidelines'').
\90\ We note that questions have been raised by, among others,
CTA and CTIA concerning NHTSA's authority to regulate portable
devices and applications. Although not at issue in these voluntary
guidelines, the agency points out that it has such authority to the
extent these technologies function as ``motor vehicle equipment'' as
defined by the Vehicle Safety Act. That said, NHTSA does not have
any current plans to develop such regulations and, as we explain
throughout, the guidelines proposed today are not regulations, but
are rather voluntary and non-binding.
\91\ 49 U.S.C. 30101 (``The purpose of this chapter is to reduce
traffic accidents and deaths and injuries resulting from traffic
accidents. Therefore it is necessary--(1) to prescribe motor vehicle
safety standards for motor vehicles and motor vehicle equipment in
interstate commerce; and (2) to carry out needed safety research and
development.''). Delegated to NHTSA at 49 CFR 1.95.

30182 were added to the Safety Act by the Moving Ahead for Progress
in the 21st Century Act (MAP-21), Public Law 112-141, 31204 (2012).
Prior to this, the Safety Act provisions authorizing NHTSA's motor
vehicle safety research and development were contained in Sec.
30168. MAP-21 deleted Sec. 30168 as redundant material. See MAP-21
Sec. 31204. Delegated to NHTSA at 49 CFR 1.95.
---------------------------------------------------------------------------
By issuing these Guidelines, NHTSA seeks to fulfill its duties
under both the Highway Safety Act and the Vehicle Safety Act. The
foundation for these Guidelines is the agency research on distraction
caused by portable and aftermarket devices, and our evaluation of
research from other experts. The agency believes that today's
guidelines are an effective way of expressing NHTSA's research
conclusions. Encapsulating and publishing research results in the form
of recommendations, best practices, or guidelines is not novel for this
agency.\95\ Further, these Guidelines are a way for NHTSA to provide
private industry with assistance on practical ways of applying the
existing research to their portable application/device designs so as to
encourage their customers to use these devices and applications
appropriately when in the motor vehicle. Moreover, by releasing these
guidelines for public comment, we are cooperating with private industry
and other members of the public toward increasing highway safety in
this important area.
---------------------------------------------------------------------------
\95\ See, e.g., Effectiveness and Acceptance of Enhanced Seat
Belt Reminder Systems: Characteristics of Optimal Reminder Systems
Final Report, DOT HS 811 097, Sec. 5.4 (``Recommended System
Characteristics'') (2009).
---------------------------------------------------------------------------
Additionally, we note that in recently enacting the Fixing
America's Surface Transportation Act,\96\ Congress included a provision
regarding the agency's ability to issue non-binding guidance. While the
provision provides that ``[n]othing in the subsection shall be
construed to confer any authority upon or negate any authority of the
Secretary to issue guidelines under this chapter,'' we note that the
only such guidelines that the agency has issued or announced plans to
issue in recent years are those relating to distraction.
---------------------------------------------------------------------------
\96\ Public Law 114-94, 24406 (2015).
---------------------------------------------------------------------------
As NHTSA has stated in various agency documents, the guidelines for
portable devices are a crucial part of a comprehensive, multi-pronged
effort to address driver distraction. Taking a comprehensive approach
that addresses behavioral, technological, and environmental risk
factors is standard practice in the injury prevention field.\97\ While
the states' achievements in addressing the behavioral aspects of
distracted driving are commendable, we believe more needs to be done to
address the other two types of risk factors. As we mentioned earlier,
the 2014 statistics show that, taking account of all different types of
distractions, a substantial portion (10%) of all fatal crashes still
involves at least one distracted driver. Further, a substantial portion
of distraction-affected fatal crashes (13%) involve cell phone use.
NHTSA estimates that 404 lives were lost in cell phone-involved fatal
crashes in that year. This represents 1.2 percent of traffic fatalities
for that year.
---------------------------------------------------------------------------
\97\ The interrelationship of the elements of this practice is
graphically depicted in the well-known analytical and planning tool
known as the Haddon Matrix.
---------------------------------------------------------------------------
Accordingly, we believe that private industry could effectively
complement the state efforts by addressing the technological risk
factors related to portable application/device use and
[[Page 87679]]
driving. Furthermore, the relationship between portable devices/
applications and driver distraction makes it incumbent upon the US DOT
to utilize NHTSA's safety expertise to assist private industry in
understanding and addressing issues related to the effects of portable
application/device design on driver behavior. The contribution of these
devices to driver distraction is an important and growing motor vehicle
safety challenge. However, manufacturers of these products generally do
not have motor vehicle safety expertise, or do not design their
products with full knowledge of the potential effects on driving,
especially those devices designed for general use, rather than
specifically for use while driving. In developing these guidelines in
consultation with industry and the public, NHTSA is using its expertise
regarding the variety of factors \98\ that adversely affect driver
performance to assist private industry in improving portable devices/
applications in ways that increase highway safety by making it easier
for the driver to avoid engaging in distracting behaviors.
---------------------------------------------------------------------------
\98\ In addition to distraction, these factors include problems
like fatigue, sleepiness, and intoxication.

VII. National Technology Transfer and Advancement Act of 1995 (NTTAA)
Under the National Technology Transfer and Advancement Act of 1995
(NTTAA) (Pub. L. 104-113), all Federal agencies and departments must
use technical standards that are developed or adopted by voluntary
consensus standards bodies, using such technical standards as a means
to carry out policy objectives or activities determined by the agencies
and departments, except when use of such a voluntary consensus standard
would be inconsistent with the law or otherwise impractical. Voluntary
consensus standards are technical standards (e.g., materials
specifications, test methods, sampling procedures, and business
practices) that are developed or adopted by voluntary consensus
standards bodies, such as SAE International (SAE). The NTTAA directs
agencies to provide Congress, through OMB, explanations when the agency
decides not to use available and applicable voluntary consensus
standards.
As part of the Phase 1 Guidelines, NHTSA identified a number of
voluntary consensus standards related to distracted driving. After
careful consideration, the agency incorporated several of these
standards into the test methods in the Phase 1 Guidelines: ISO
International Standard 15008:2003, ``Road vehicles--Ergonomic aspects
of transport information and control systems--Specifications and
compliance procedures for in-vehicle visual presentation''; ISO
International Standard 16673:2007(E), ``Road Vehicles--Ergonomic
Aspects of Transport Information and Control Systems--Occlusion Method
to Assess Visual Demand due to the use of In-Vehicle Systems''; and
multiple versions of SAE Recommended Practice J941, ``Motor Vehicle
Drivers' Eye Locations,'' including SAE J941 (June 1992), SAE J941
(June 1997), SAE J941 (September 2002), SAE J941 (October 2008), and
SAE J941 (March 2010). Because the proposed Phase 2 Guidelines involve
the use of the Phase 1 Guidelines test procedure, with several
modifications, as described in
[[Page 87680]]
detail above, these standards are, by extension, included by reference
in the Phase 2 Guidelines.
The agency requests comment on any other voluntary consensus
standards appropriate for use in these Guidelines.
Visual-Manual NHTSA Driver Distraction Guidelines for Portable and
Aftermarket Devices (Phase 2 Guidelines)
I. Purpose
The purpose of the NHTSA driver distraction guidelines is to reduce
the number of motor vehicle crashes and the resulting deaths and
injuries that occur due to a driver being distracted from the primary
driving task while performing secondary activities with a portable or
aftermarket device within the vehicle.
Phase 2 extends and tailors the recommendations specified in the
Phase 1 Visual-Manual NHTSA Driver Distraction Guidelines for In-
Vehicle Electronic Devices (henceforth referred to as ``Phase 1
Guidelines'') to cover portable and aftermarket devices. These
Guidelines are presented as an aid to vehicle manufacturers, portable
and aftermarket device manufacturers, developers, carriers, and
application developers in designing products that discourage unsafe
driver distraction resulting from use of the devices. Adherence to
these guidelines is voluntary and conformance with them is not
required.
A. Driver Responsibilities
These Guidelines are meant to reduce the potential distraction
associated with portable and aftermarket device interfaces. A portable
or aftermarket device's conformance with these Guidelines does not mean
that the device is safe to use while driving. It remains the driver's
responsibility to ensure the safe operation of the vehicle under all
operating conditions and to comply with all traffic laws, including
those that ban texting and/or the use of hand-held devices while
driving.
II. Scope
A. Devices and Interfaces
1. General Device and Interface Applicability. These Guidelines are
applicable to the visual-manual portions of a portable or aftermarket
device's human-machine interface. These Guidelines are applicable to
device interfaces regardless of the class or size of the vehicles in
which the portable or aftermarket devices may be used.

nor involve the use of a system required by law. Examples of driving-
related tasks to which these Guidelines are applicable include:
1. Driver Information functions
2. Route navigation functions.
2. Exclusions. These Guidelines are not applicable to the driving-
related tasks that are performed by the driver as part of the safe
operation and control of the vehicle, including any task relating to
the proper use of a driver safety warning system (e.g., lane departure
warning and forward collision warning systems). These include
applications for portable and aftermarket devices that assist the
driver in the mitigation and avoidance of crashes.
III. Definitions
A. Definitions From the Phase 1 Guidelines
The following terms are defined in the Phase 1 Guidelines, and have
the same meaning in these Guidelines:
1. Device means all components that a driver uses to perform
secondary tasks (i.e., tasks other than the primary task of safe
operation and control of the vehicle); whether stand-alone or
integrated into another device.
2. Distraction means the diversion of a driver's attention from
activities critical for safe operation and control of a vehicle to a
competing activity.
3. Driving means whenever the vehicle's means of propulsion (engine
and/or motor) is activated unless one of the following conditions is
met:
a. For a vehicle equipped with a transmission with a ``Park''
position--The vehicle's transmission is in the ``Park'' position.
b. For a vehicle equipped with a transmission without a ``Park''
position--All three of the following conditions are met:
i. The vehicle's parking brake is engaged, and
ii. The vehicle's transmission is known (via direct measurement
with a sensor) or inferred (by calculating that the rotational speed of
the engine divided by the rotational speed of the driven wheels does
not equal, allowing for production and measurement tolerances, one of
the overall gear ratios of the transmission/vehicle) to be in the
neutral position, and
iii. The vehicle's speed is less than 5 mph.
4. Function means an individual purpose which the device is
designed to fulfill. A device may have one or more functions.
[[Page 87681]]
5. Interaction means an input by a driver to a device, either at
the driver's initiative or as a response to displayed information.
Interactions include control inputs and data inputs (information that a
driver sends or receives from the device that is not intended to
control the device). Depending on the type of task and the goal,
interactions may be elementary or more complex. For the visual-manual
interfaces covered by this version of these Guidelines, interactions
are restricted to physical (manual or visual) actions.
6. Lock Out means the disabling of one or more functions or
features of a device so that the related task cannot be performed by
the driver while driving.
7. Manual Text Entry means manually inputting individual
alphanumeric characters into an electronic device. For the purposes of
these Guidelines, digit-based phone dialing is not considered manual
text entry.
B. Additional Definitions
1. Aftermarket Device means a Device that is designed to be or can
reasonably be expected to be installed or integrated into a vehicle
after the vehicle is manufactured, is electrically powered, and has one
or more of the following capabilities:
a. Allows user interaction;
b. Enters, sends, and/or receives information;
c. Enables communication with other people, devices, or machines;
d. Displays information in a visual and/or auditory manner; or
e. Displays graphical images, photographic images, and/or video.
2. Application, or App, means a specialized software program that
is installed on an OEM, portable or aftermarket device.
3. Driver Mode means a simplified user interface for an unpaired
portable device that is designed for operation by a driver while
driving.
4. Driver safety warning system means a system or application that
is intended to assist the driver in the avoidance or mitigation of
crashes.
5. Human-Machine Interface (HMI) means the input and output
mechanisms that mediate the interactivity between an electronic system
and human operator. User Interface (UI) is another commonly used term
for HMI.
6. In-Vehicle System means an OEM or aftermarket system that is
permanently installed.
7. PAD means a portable or aftermarket device.
8. Paired means integrated, connected, or coupled to an in-vehicle
system's visual display, audio system, and/or controls through either
wired or wireless connection methods so that the in-vehicle system has
control over the portable device's prioritization, manipulation, and
the presentation of information that originates from both local and/or
off-board sources.
9. Portable Device means a device that can reasonably be expected
to be brought into a vehicle on a trip-by-trip basis and to be used by
a driver while driving, that is electrically powered, and that has one
or more of the following capabilities:
a. Allows user interaction
b. Enters, sends, and/or receives information
c. Displays information in a visual and/or auditory manner, or
d. Displays graphical images, photographic images, and/or video
IV. Device Interface Recommendations
A. Overview of Device Interface Recommendations
Figure 2 below is a flow diagram that summarizes the overall
recommendations for both portable and aftermarket devices. For the
Driver Mode recommendation, the diagram depicts the preferred automatic
activation with the recognition that driver distinction technology is
not currently available in a product-level state. When the distinction
technology matures to an implementable state, NHTSA strongly recommends
that it be applied to managing the interaction of unpaired portable
devices. Manual activation of Driver Mode by the driver, also depicted
in Figure 2, is NHTSA's temporary recommendation until the preferred
automatic activation configuration is available. For the remainder of
this section, the recommendations for aftermarket and portable devices
are presented separately.

B. Aftermarket Devices
Installed aftermarket devices should meet the requirements as
specified for OE interfaces in the Phase 1 Guidelines.
C. Portable Devices Should Be Paired
1. Ease of Pairing
Vehicle manufacturers and portable device manufacturers should
provide the necessary mechanisms to enable pairing between the portable
device and in-vehicle system. Pairing should be an easy-to-understand
task that allows the driver to set up their portable device with their
in-vehicle system with the fewest number of steps possible.
2. Disablement of Pairing Process
If the initial or subsequent pairing process between the portable
device and in-vehicle system requires visual-manual interaction by the
driver, the initial process of pairing should be disabled while
driving.
3. Portable Device Interface Lock Outs While Paired
Portable device control input means should be locked out when the
portable device is paired to the in-vehicle system and Driver mode on
the device is activated. The functions and applications on the portable
device should be operable exclusively through the in-vehicle system's
interface with the exception of accessing emergency services and
messages.
4. Emergency Services, Alerts, and Notifications
In the event that emergency services are required, access through
the locked out paired portable device interface should be quick and
easily accessible for the driver. Along with access to emergency
services, the receiving of emergency notifications and alerts as text
messages should be allowable for display on the paired portable device
interface. All emergency messaging and alert services should follow the
standard protocol as specified by the Wireless Emergency Alerts (WEA)
system which is managed by the Federal Communications Commission (FCC)
and the Federal Emergency Management Agency (FEMA).
D. Portable Devices Should Incorporate Driver Mode for Unpaired Use
1. Driver Mode
Portable devices should have a Driver Mode that consists of a
simplified interface that is available to the driver when the device is
unpaired, either because the in-vehicle system and/or portable device
does not possess the capability for pairing or because the driver
chooses not to pair with the in-vehicle system. However, a portable
device designed primarily for use while driving and whose native
interface design conforms to the Phase 1 Guidelines recommendations can
be considered to essentially always be in driver mode and therefore
would not warrant a separate mode for use while driving.
The Driver Mode interface should conform to the Phase 1 Guidelines
for electronic devices used by the driver while driving. Specifically,
while in Driver Mode, the portable device should adhere to the per se
lock out tasks listed in sections V.F.1 through V.F.6 of the Phase 1
Guidelines.
[[Page 87683]]
1. Device functions and tasks not intended to be used by a driver while
driving
2. Manual text entry
3. Displaying video
4. Displaying images
5. Automatically scrolling text
6. Displaying text to be read
Driver Mode should also lock out any non-driving-related task or
driving-related task that does not conform to one of the task
acceptance methods in Section VI of these Guidelines. The portable
device should also conform to the following subsections of the Phase 1
Guidelines Section V:
A. No Obstruction of View
B. Easy to See and Reach
F. Per Se Lock Outs (listed in previous paragraph)
G. Acceptance Test-Based Lock Out of Tasks
H. Sound Level
I. Single-Handed Operation
J. Interruptibility
K. Device Response Time
L. Disablement
M. Distinguish Tasks or Functions not intended for use while driving
N. Device Status
2. Emergency Services, Alerts, and Notifications
In the event that emergency services are required, access through
the portable device Driver Mode interface should be quick and easily
accessible for the user. Along with access to emergency services, the
receiving of emergency notifications and alerts as text messages should
be allowable for display on the Driver Mode interface. All emergency
messaging and alert services shall follow the standard protocol as
specified by the WEA system which is managed by the FCC and the FEMA.
3. Driver Mode Activation
a. Option 1--Automatic Activation. Driver mode automatically
activates within a reasonable period of time when the portable device:
(1) Is not paired with the in-vehicle system, and (2) by itself, or in
conjunction with the vehicle in which it is being used, distinguishes
that it is being used by a driver who is driving. The driver mode does
not activate when the device is being used by a non-driver.
i. Development of technologies that can distinguish between a
device being used by a driver and a device being used by a passenger
and appropriately alter, limit, or eliminate their visual-manual
interfaces when used by a driver is encouraged. In the case in which
Driver Mode is automatically activated in a moving vehicle, the
technology should be able to distinguish the driver-operated devices
from the passenger-operated devices to a high-degree of accuracy and
reliability; and be executed in a prompt manner relative to the
starting motion of the driver's vehicle.
b. Option 2--Driver Activation. Driver Mode is activated by the
driver before driving. If this option is used, Driver Mode should be
easily accessible via the portable device's software or hardware user
interface, enabling the driver to engage Driver Mode quickly and with
the fewest number of steps possible.
4. Unpaired Portable Device Location
A specific location for an unpaired portable device (e.g., mounting
location) is not specified in these guidelines. The test location
described in the Task Acceptance Testing section is for testing
purposes only and not considered a recommendation for device placement.
V. Task Acceptance Testing
Task acceptance testing for portable devices should use the same
test methods as those described in the Phase 1 Guidelines Section VI.
The specific procedures for Eye Glance Measurement Using Driving
Simulator Testing and Occlusion Testing are incorporated by reference,
as detailed in the following subsections of the Phase 1 Guidelines
Section VI:
A. Test Participant Recommendations.
B. Test Participant Training Recommendations.
C. Driving Simulator Recommendations.
D. Recommended Driving Simulator Scenario.
E. Eye Glance Measurement Using Driving Simulator Test Procedure.
F. Eye Glance Characterization.
G. Occlusion Testing.
H. Text Performance Errors During Testing.
The Acceptance Criteria detailed in the Phase 1 Guidelines for both
the Simulator (Section VI.E.14) and Occlusion (Section VI.G.17) test
methods are also applicable for testing portable devices.
A. Additional Test Procedures for Portable and Aftermarket Devices
1. Permanently Installed Aftermarket Devices. Devices that are
intended to be permanently installed in the vehicle should be tested in
the location prescribed by the device manufacturer, and according to
the test procedures noted above. Such prescribed installation locations
should conform to the guidelines specified in the following subsections
from Phase 1 Guidelines Section V:
A. No Obstruction of View.
B. Easy to See and Reach.
C. Maximum Display Downward Angle.
D. Lateral Position of Visual Displays.
2. Paired Devices: Testing procedures assume the portable device is
already paired to the vehicle system, as defined in Section III.
Because the testing of the paired portable device will use the built-in
display and controls system, the location of the paired portable device
itself is not specified.
3. Unpaired Devices: Unpaired portable devices should only be
tested in a mounted location using tasks that are accessed through the
Driver Mode interface. NHTSA recognizes that there are substantial
variations in portable device mounting hardware options and vehicle
interior designs that are available to drivers. As such, unpaired
portable devices should be mounted within a vehicle to the greatest
extent possible to the following recommendations:
a. The mount location should conform to the recommendations
specified in the Phase 1 Guidelines Section V.A through Section V.D
noted above.
b. The mounting location should not result in the portable device
interfering with airbag deployment zones or safe operation of the
vehicle controls (e.g., steering wheel, gear shifter, etc.).
VI. Driver Distraction Guidelines Interpretation Letters
NHTSA intends to clarify the meaning of its Driver Distraction
Guidelines in response to questions posed through the issuance of
interpretation letters.
A. Guideline Interpretation Letter Procedure
1. Guidelines interpretation letters will only be issued in
response to specific written requests for interpretation of the NHTSA
Guidelines.
2. Requests for Guidelines interpretation letters may be submitted
to the National Highway Traffic Safety Administration. The mailing
address is: Chief Counsel, NCC-200, National Highway Traffic Safety
Administration, 1200 New Jersey Ave. SE., Washington, DC 20590.
3. Responses will be mailed to requestors, published in the docket,
