II. Executive Summary

A. Purpose and Summary of the Regulatory Action

    Section 393.60(e)(1)(i) of the FMCSRs prohibits obstruction of the 
driver's field of view by devices mounted at the top of the windshield. 
Antennas and similar devices must not be mounted more than 152 mm (6 
inches) below the upper edge of the windshield and must be outside the 
driver's sight lines to the road and highway signs and signals.
    Section 393.60(e)(1)(i) does not apply to vehicle safety 
technologies, as defined in Sec.  393.5, that include ``a fleet-related 
incident management system, performance or behavior management system, 
speed management system, forward collision warning or mitigation 
system, active cruise control system, and transponder.'' Section 
393.60(e)(1)(ii) requires devices with vehicle safety technologies to 
be mounted (1) not more than 100 mm (4 inches) below the upper edge of 
the area swept by the windshield wipers, or (2) not more than 175 mm (7 
inches) above the lower edge of the area swept by the windshield 
wipers, and (3) outside the driver's sight lines to the road and 
highway signs and signals.
    The Agency modifies Sec.  393.60(e)(1)(ii) to increase from 100 mm 
(4 inches) to 216 mm (8.5 inches) the distance below the upper edge of 
the area swept by the windshield wipers within which vehicle safety 
technologies may be mounted. The Agency also amends Sec.  393.5 by 
revising the definition of vehicle safety technology to add 
technologies that had been granted temporary exemptions from Sec.  
393.60(e). The amendments do not impose new or more stringent 
requirements, but simply codify the temporary exemptions granted 
pursuant to 49 CFR part 381 that allow the use of the devices/
technologies in locations that would previously have been a violation 
of Sec.  393.60(e)(1). More importantly, the amendments do not mandate 
the use of any devices/technologies, but simply permit their voluntary 
use while mounted in a location that maximizes their effectiveness 
without impairing operational safety.

B. Costs and Benefits

    The Agency expects that the final rule will generate cost savings 
for both industry and the Federal Government by reducing the overall 
time burden associated with the exemption request and approval process 
associated with 49 U.S.C. 31315(b) and the implementing regulations 
under 49 CFR part 381. The Agency estimates this final rule will result 
in total annualized cost savings of $10,903 at 3 percent and 7 percent 
discount rates, respectively.

IV. Legal Basis for the Rulemaking

    This final rule is based on the authority of the Motor Carrier Act, 
1935 (1935 Act), the Motor Carrier Safety Act of 1984 (1984 Act), and 
the Fixing America's Surface Transportation (FAST) Act.
    The 1935 Act, as amended, provides that ``[t]he Secretary of 
Transportation may prescribe requirements for--(1) qualifications and 
maximum hours of service of employees of, and safety of operation and 
equipment of, a motor carrier; and (2) qualifications and maximum 
hours-of-service of employees of, and standards of equipment of, a 
motor private carrier, when needed to promote safety of operation.'' 
(49 U.S.C. 31502(b)).
    The 1984 Act provides concurrent authority to regulate drivers, 
motor carriers, and vehicle equipment. It requires the Secretary to 
``prescribe regulations on commercial motor vehicle safety. The 
regulations shall prescribe minimum safety standards for commercial 
motor vehicles. At a minimum, the regulations shall ensure that--(1) 
commercial motor vehicles are maintained, equipped, loaded, and 
operated safely; (2) the responsibilities imposed on operators of 
commercial motor vehicles do not impair their ability to operate the 
vehicles safely; (3) the physical condition of operators of commercial 
motor vehicles is adequate to enable them to operate vehicles safely . 
. . ; (4) the operation of commercial motor vehicles does not have a 
deleterious effect on the physical condition of the operators; and (5) 
an operator of a commercial motor vehicle is not coerced by a motor 
carrier, shipper, receiver, or transportation intermediary to operate a 
commercial motor vehicle in violation of a regulation promulgated under 
this section, or chapter 51 or chapter 313 of this title.'' (49 U.S.C. 
31136(a)).
    Section 5301 of the FAST Act directs FMCSA to exempt voluntary 
mounting of a vehicle safety technology on a windshield if that 
technology is likely to achieve a level of safety that is equivalent to 
or greater than the level of safety that would be achieved without the 
exemption (Pub. L. 114-94, 129 Stat. 1312, 1543, Dec. 4, 2015). Section 
5301(c) also specifies that any regulatory exemption for windshield-
mounted technologies in effect on the date of enactment of the FAST Act 
``shall be considered likely to achieve a level of safety that is 
equivalent to or greater than the level of safety that would be 
achieved absent an exemption. . . .''
    This final rule is based in part on the 1935 Act, which allows the 
Agency to regulate the ``safety of operation and equipment'' of a motor 
carrier and the ``standards of equipment'' of a motor private carrier. 
The requirements of 49 U.S.C. 31136(a)(1), (2), and (4) of the 1984 Act 
are also applicable to this rulemaking action. The Agency amends 49 CFR 
part 393 to allow certain safety equipment to be mounted within the 
area of the windshield swept by the windshield wipers. The Agency 
believes that these changes will be welcomed by motor carriers and 
drivers alike and that coercion to violate these revised provisions, 
which is prohibited by Sec.  31136(a)(5), will not be an issue. The 
final rule does not involve the physical condition of drivers under 
Sec.  31136(a)(3).
    This final rule rests in part on the intent of Congress expressed 
in section 5301 of the FAST Act to exempt safety equipment mounted 
within the swept area of windshields, provided such devices do not 
degrade operational safety.
    FMCSA must consider the ``costs and benefits'' of any proposal 
before promulgating regulations (49 U.S.C. 31136(c)(2)(A), 31502(d)).

V. Discussion of Proposed Rulemaking

A. Proposed Rulemaking

    On July 6, 2021, FMCSA published in the Federal Register a Notice 
of Proposed Rulemaking (NPRM) (Docket No. FMCSA-2021-0037, 86 FR 35449) 
titled ``Parts and Accessories Necessary for Safe Operation; Authorized 
Windshield Area for the Installation of Vehicle Safety Technology.'' 
The NPRM proposed to modify 49 CFR 393.60(e) to allow certain vehicle 
safety technologies to be mounted on the interior of the windshield of 
a CMV, within a defined portion of the swept area of the windshield. 
The NPRM also proposed to modify the definition of vehicle safety 
technology in 49 CFR 393.5 to add technologies that had been granted 
temporary exemptions from Sec.  393.60(e) since the 2016 final rule.

B. Comments and Responses

1. Responses to Questions Posed in NPRM
    The comment period closed on August 5, 2021. The following 17 
parties submitted comments: American Trucking Associations (ATA); Car 
Couriers Inc.; Daimler Trucks North America LLC (DTNA); EROAD; 
Fastfreight Express; Lidar Coalition; Lytx, Inc.; Motor & Equipment 
Manufacturers Association (MEMA); Netradyne, Inc.; Omnitracs, LLC and 
SmartDrive Systems; Owner-Operator Independent Drivers Association 
(OOIDA); Samsara Inc.; Truck and Engine Manufacturers Association 
(EMA); United Motorcoach Association (UMA); ZF North America; and two 
private citizens.
    To assist in development of the proposed regulatory revisions, the 
Agency requested responses to two specific questions.
    Question 1: Does the definition of vehicle safety technology need 
to be expanded further to address other potential technologies and/or 
multifunction devices such as electronic logging devices that 
incorporate technologies such as Global Positioning Systems (GPS) that 
either require placement in the approximate middle of the CMV 
windshield or would benefit driver safety by not diverting the CMV 
driver's eyes from the road and would be subject to the positioning 
requirements of Sec.  393.60(e)(1)?
    Responses: Most commenters supported the proposed definition of 
vehicle safety technology from the NPRM. Some commenters added that the 
proposed definition does not need to be expanded further and should be 
finalized as written.
    Some commenters stated that the proposed definition of vehicle 
safety technology provides adequate flexibility by not restricting the 
definition to the listed safety technology examples. DTNA requested 
FMCSA clarify that the list of technologies in the definition is not 
exclusive. DTNA stated that this clarification could be made by 
revising the definition of vehicle safety technology to read, in part, 
``Examples of vehicle safety technology systems and devices include, 
but are not limited to . . .'' and ``Vehicle safety technology includes 
but is not limited to. . . .'' DTNA stated that this change to the 
definition would clarify that the list is not all-encompassing, allow 
for multi-function devices, and prevent the need for exemption requests 
in the future for emerging technologies, while still ensuring that the 
covered technologies would be limited to those that have an impact on 
and promote vehicle safety.
    Lidar Coalition proposed revising the first sentence of the 
definition of vehicle safety technology to read as follows:

    Vehicle safety technology includes systems, components, and 
items of

[[Page 12598]]

equipment used to assist in managing any aspect of the dynamic 
driving task (as defined in SAE J3016), or improve the safety of 
drivers, occupants, and other road users (such as pedestrians or 
cyclists).

Lidar Coalition stated that this revision would focus the definition on 
Advanced Driver Assistance System technology and broaden the potential 
beneficiaries of such technology to include all road users.
    ATA agreed with the proposed definition and stated that FMCSA 
should continue to update the definition of vehicle safety technology 
in the future after evaluating new devices with sound data 
demonstrating safety performance at and above the current standard.
    Some commenters expressed general support for adding GPS and 
Electronic Logging Device (ELD) systems to the definition of vehicle 
safety technology, stating that these devices enhance safety. A few 
commenters supported the addition of GPS devices to the definition of 
vehicle safety technology so those devices can be positioned closer to 
the driver's line of sight and the drivers do not need to look away 
from the road to view them. Some commenters stated that ELDs do not 
need to be mounted on windshields for the operation of the device and 
that such placement would cause an unnecessary distraction. A few 
commenters stated that GPS and ELD systems may be integrated with other 
devices listed in the definition of vehicle safety technology that 
could be placed on the windshield and therefore needed to be included 
in the definition.
    The Lidar Coalition supported inclusion of lidar in the proposed 
definition, stating that such systems will provide multiple safety 
benefits when mounted on the interior of windshields.
    MEMA stated that the windshield space should be prioritized for 
safety systems that require a clear and clean windshield to operate, 
such as a forward-looking camera, and not systems that can function 
from other positions, such as a GPS unit.
    OOIDA expressed concern that the proposed definition of vehicle 
safety technology includes some technologies that are proven to 
increase the likelihood of crashes or need more research to determine 
their effect on vehicle safety, such as speed management systems, 
automatic emergency braking (AEB) systems, and equipment being deployed 
on autonomous vehicles. OOIDA stated that FMCSA should not mandate use 
of these technologies.
    UMA commented that some States may have adopted laws that would 
conflict with the proposed definition of vehicle safety technology and 
provided an example of a California law that would be in conflict with 
the proposed definition. The California law cited by UMA states that a 
GPS device ``may be mounted in a seven-inch square in the lower corner 
of the windshield farthest removed from the driver or in a five-inch 
square in the lower corner of the windshield nearest to the driver'' 
and a video event recorder ``may be mounted in a seven-inch square in 
the lower corner of the windshield farthest removed from the driver, in 
a five-inch square in the lower corner of the windshield nearest to the 
driver and outside of an airbag deployment zone, or in a five-inch 
square mounted to the center uppermost portion of the interior of the 
windshield.'' UMA requested that FMCSA ensure regulations integrate 
with such State laws or address the preemptive intention of the final 
rule.
    FMCSA response: This final rule adopts the changes proposed in the 
NPRM. It is consistent with the following previously issued Agency 
actions permitting the placement of vehicle safety technology devices 
on CMVs outside the driver's sight lines to the road, and highway signs 
and signals: Bendix Commercial Vehicle Systems, LLC 86 FR 17877 (Apr. 
6, 2021), Netradyne, Inc. 85 FR 82575 (Dec 18, 2020), J.J. Keller & 
Associates, Inc. 85 FR 75106 (Nov. 24, 2020), Samsara Networks, Inc. 85 
FR 68409 (Oct. 28, 2020), Nauto Inc. 85 FR 64220 (Oct. 9, 2020), Lytx 
Inc. 85 FR 30121 (May 21, 2020), Navistar Inc. 84 FR 64952 (Nov. 25, 
2019), SmartDrive System, Inc. 84 FR 15284 (Apr. 15, 2019), Daimler 
Trucks North America LLC 83 FR 4543 (Jan. 31, 2018), and Hino Motors 
Manufacturing U.S.A. 82 FR 36182 (Aug. 3, 2017). All of the temporary 
exemptions were granted for devices that meet the definition of vehicle 
safety technologies except for the GPS device identified in the 
Traditional Trucking Corp. exemption (83 FR 42552, Aug. 22, 2018). The 
Agency also acknowledges that many devices such as ELDs may include GPS 
technology. Under the final rule, any device that incorporates GPS is 
included in the definition of vehicle safety technology.
    When issuing the previous exemptions, the Agency asked interested 
parties to provide FMCSA with any information demonstrating that motor 
carriers operating CMVs equipped with vehicle safety technologies are 
not achieving the requisite statutory level of safety. FMCSA has not 
received any information to that effect.
    As noted in the NPRM, the proposed amendment would not require the 
use of any devices or technologies but would simply permit their 
voluntary use when mounted in a location that maximizes their 
effectiveness without impairing operational safety. FMCSA is unaware of 
any evidence showing that installation of other vehicle safety 
technologies mounted on the interior of the windshield has resulted in 
any degradation in safety.
    Regarding OOIDA's concern about speed management and AEB systems, 
FMCSA sees no reason to remove ``speed management systems'' from the 
definition of vehicle safety technology. The definition has included 
``speed management systems'' since it was originally added to 49 CFR 
393.5 (81 FR 65568, Sep. 23, 2016). In the absence of data to support 
OOIDA's claims that these technologies are proven to increase the 
likelihood of crashes or need more research to determine their effect 
on vehicle safety, FMCSA sees no reason to revisit those technologies 
inclusion in the definition. As to AEB, FMCSA notes that section 393.5 
continues to include ``forward collision warning or mitigation system'' 
as one example of vehicle safety technology excepted from the 
windshield obstruction prohibition in section 393.60(e). While AEB was 
included in the definition proposed in the petition for rulemaking, 
section 23010 of the Infrastructure Investment and Jobs Act (Pub. L. 
117-56, Nov. 15, 2021) requires the National Highway Traffic Safety 
Administration (NHTSA) to complete a rulemaking on AEB and FMCSA to 
complete a companion rulemaking. AEB technology ultimately might or 
might not require placement within the swept area of the windshield 
wipers. Under the circumstances, the Agency has decided that it would 
be premature to address AEB in this final rule. Additionally, the NPRM 
did not propose, and this final rule does not require, installation of 
these technologies.
    States that accept Motor Carrier Safety Assistance Program (MCSAP) 
funds from FMCSA must adopt laws or regulations compatible with the 
rules in 49 CFR parts 390-397 within 3 years of the effective date of a 
new rule (49 CFR 350.335(a)(2)) or risk the loss of such funds. That 
MCSAP requirement would apply to States that have regulations on the 
location of safety technologies in CMV windshields inconsistent with 
this final rule.
    Question 2: Would the proposed position of allowable vehicle safety 
technologies (8.5 inches below the upper and 7 inches above the lower 
edge of the swept area of the

[[Page 12599]]

windshield) be sufficient for current and developing devices?
    Responses: Most commenters supported the dimensions proposed in the 
NPRM as sufficient for current and developing devices. Some commenters 
stated that existing technologies have been placed within the 
dimensions proposed in the NPRM, under previous exemptions, without 
obstructing the driver's view or causing any adverse safety impacts.
    A few commenters stated that devices placed within the dimensions 
proposed in the NPRM could obstruct the driver's view of pedestrians, 
cars, and buildings. Some argued that the NPRM fails to account for 
drivers of different heights and that taller drivers are more likely to 
have their view obstructed by safety devices in the proposed areas of 
the windshield. Fastfreight Express provided pictures showing how 
safety devices on the windshield obstructed the view of cars and 
buildings.
    ATA stated that devices on the windshield could require more or 
less physical space on the windshield in the future depending on how 
technologies develop, but that these changes should not be incompatible 
with the proposal.
    A few commenters stated that the proposed position of allowable 
vehicle safety technologies might not be sufficient for some vehicle 
types covered by the regulations, such as tractors with split 
windshields, refuse trucks, motorcoaches, over-the-road-buses, and 
school buses.
    UMA questioned whether limiting the number of devices on the 
windshield is appropriate.
    FMCSA response: FMCSA has granted temporary exemptions that allow 
safety technologies to be placed 8.5 inches below the upper and 7 
inches above the lower swept area of the windshield wipers, all without 
objection from commenters. FMCSA acknowledges the concerns expressed by 
several commenters that the sightlines of taller drivers could be 
obstructed by safety devices mounted high on the windshield. Drivers 
currently deal with a variety of visual obstructions from the seating 
position, including the cab's A pillars on each side of the windshield, 
the sun visor (when pulled down), and the external mirrors (which may 
be larger than the minimum size required by NHTSA). All of these 
obstructions are legal, and drivers adapt by moving their upper body 
and head to obtain a clear sightline to their surroundings. FMCSA has 
received no information that these obstructions or the safety devices 
placed in the swept area of windshields under previously granted 
temporary exemptions have created visual obstructions that cannot be 
addressed by the driver's routine movements of the head or upper body. 
Regarding the UMA comment on limiting the number of devices on the 
windshield, the Agency has not received information from previously 
granted temporary exemptions that a limitation on the number of devices 
is necessary and therefore declines to make that change in this final 
rule.

VI. Changes From the NPRM

    The Agency is making one change to this final rule from the NPRM. 
The Agency removes ``automatic emergency braking,'' from the definition 
for vehicle safety technology.

VII. Section-by-Section Analysis

    This section-by-section analysis describes the changes in numerical 
order.

A. Section 393.5 Definitions

    The definition for vehicle safety technology is revised by adding 
more examples of vehicle safety technologies to those listed in the 
definition.

B. Section 393.60 Glazing in Specified Openings

    This section is revised by replacing ``100 mm (4 inches)'' with 
``216 mm (8.5 inches)'' in paragraph (e)(1)(ii)(A). Additionally, a new 
paragraph (e)(1)(ii)(C) is added to read ``Outside the driver's sight 
lines to the road and highway signs and signals.''

VIII. Regulatory Analyses

A. Executive Order (E.O.) 12866 (Regulatory Planning and Review), E.O. 
13563 (Improving Regulation and Regulatory Review), and DOT Regulatory 
Policies and Procedures

    FMCSA has considered the impact of this notice of rulemaking under 
E.O. 12866 (58 FR 51735, Oct. 4, 1993), Regulatory Planning and Review, 
E.O. 13563 (76 FR 3821, Jan. 21, 2011), Improving Regulation and 
Regulatory Review, and DOT's regulatory policies and procedures. The 
Office of Information and Regulatory Affairs (OIRA) determined that 
this rulemaking is not a significant regulatory action under section 
3(f) of E.O. 12866, as supplemented by E.O. 13563, and does not require 
an assessment of potential costs and benefits under section 6(a)(3) of 
that Order. Accordingly, the Office of Management and Budget (OMB) has 
not reviewed it under that E.O.
    As stated previously under our discussion of public comments, we 
received 17 comments. Thirteen of these comments supported increasing 
the area within which certain vehicle safety technology devices may be 
mounted on the interior of the CMV windshields and the Agency proposal 
to add items to the definition of vehicle safety technology.
    There are two differences in this regulatory analysis from the 
regulatory analysis in the NPRM that have a quantified monetary impact. 
The NPRM used the most up-to-date wage data then available to estimate 
cost savings to (1) motor carrier companies that would have to file 
fewer periodic exemption requests, and (2) the Federal Government by 
reducing the volume of exemption requests to be reviewed and processed. 
More up-to-date wage data are now available and utilized for this final 
rule. Other than these two modifications, there are no substantive 
changes to the requirements and calculations originally proposed in the 
NPRM.
Baseline for the Analysis
    The mounting of devices on the interior and within the swept area 
of the windshield is prohibited under 49 CFR 393.60(e), unless they are 
vehicle safety technologies. FMCSA has authority under 49 U.S.C. 
31315(b) to grant exemptions from certain parts of the FMCSRs. FMCSA 
must publish a notice of each exemption request in the Federal Register 
(49 CFR 381.315(a)). The Agency must provide the public an opportunity 
to inspect the information relevant to the application, including any 
safety analyses that have been conducted. The Agency must also provide 
an opportunity for public comment on the request. FMCSA notes that the 
burden associated with preparing an exemption request is not included 
in a currently approved information collection request (ICR), and the 
Agency is pursuing completion of that ICR outside of this rulemaking.
    As originally enacted, 49 U.S.C. 31315(b) allowed an exemption from 
a regulation (and a renewal) for no longer than 2 years from its 
approval date. Section 5206(a)(3) of the FAST Act amended section 
31315(b) to allow an exemption to be granted for no longer than 5 years 
and to be renewed, upon request, for subsequent periods no longer than 
5 years. 49 CFR 381.300(b).
    Section 393.60(e)(1)(i) of the FMCSRs prohibits the obstruction of 
the driver's field of view by devices mounted on the interior of the 
windshield. Antennas and similar devices must not be mounted more than 
152 mm (6 inches) below the upper edge of the windshield, and outside 
the driver's sight lines to the road and highway signs and signals. 
Section 393.60(e)(1)(i) does not apply to vehicle safety technologies, 
as defined in 49 CFR 390.5, including ``a fleet-

[[Page 12600]]

related incident management system, performance or behavior management 
system, speed management system, lane departure warning system, forward 
collision warning or mitigation system, active cruise control system, 
and transponder.'' Section 393.60(e)(1)(ii) requires devices with 
vehicle safety technologies to be mounted (1) not more than 100 mm (4 
inches) below the upper edge of the area swept by the windshield 
wipers, or (2) not more than 175 mm (7 inches) above the lower edge of 
the area swept by the windshield wipers, and outside the driver's sight 
lines to the road and highway signs and signals.
    This final rule revises 49 CFR 393.60 to expand the area where 
vehicle safety technologies (e.g., lane departure warning systems, 
forward collision warning or mitigation systems, active cruise control 
systems, and transponders) may be installed on the interior of 
windshields of CMVs. The final rule will generate cost savings for both 
industry and government and will achieve a level of safety equivalent 
to, or greater than, the level achieved by the current regulation.
    In table 1, we show a summary of the impacts of the final rule. As 
a result of the previously discussed changes between this regulatory 
analysis and the NPRM, the projected cost savings to industry and the 
Federal government have increased. The annualized and 10-year cost 
savings to industry, both discounted 7 percent, increased approximately 
9 percent from the NPRM estimates of $568 and $3,992 to $621 and 
$4,361, respectively. The annualized and 10-year cost savings to the 
Federal government, both discounted 7 percent, increased approximately 
1 percent, from the NPRM estimates of $10,137 and $71,197 to $10,282 
and $72,214, respectively. As a result, the aggregated annual and 10-
year cost savings for both the private sector and the Federal 
government, discounted at 7 percent, increased approximately 2 percent, 
from $10,705 and $75,189 to $10,903 and $76,575, respectively.

                                technologies which have the potential to
                                reduce fatalities, injuries, and
                                property damages while maintaining a

                                greater than, the level achieved by the
                                current regulation.
------------------------------------------------------------------------

Cost, Cost Savings, and Benefits
    This final rule makes two changes to the Parts and Accessories 
Necessary for Safe Operation regulations in 49 CFR part 393, subpart A 
and subpart D.
    Under the existing Sec.  393.5 Definitions, vehicle safety 
technology includes a fleet-related incident management system, 
performance or behavior management system, speed management system, 
lane departure warning system, forward collision warning or mitigation 
system, active cruise control system, and transponder. Under the final 
rule, this definition will also include braking warning systems, 
braking assist systems, driver camera systems, attention assist 
warning, GPS, and traffic sign recognition. Vehicle safety technology 
includes systems and devices that contain cameras, lidar, radar, 
sensors, and/or video.
    As a result, vehicle safety technologies will expand to cover new 
devices and systems and better accommodate the advanced driver 
assistance technologies. The change will have no cost. Benefits will 
accrue through improved safety performance of CMVs via prevention or 
reduction of fatalities, injuries, and property damage. For example, 
lane departure warning systems are anticipated to prevent accidents 
involving striking a car in an adjoining lane, which could either 
involve ``sideswiping'' a vehicle traveling in the same direction or 
hitting a vehicle traveling in the opposite direction. Section 
393.60(e)(1)(ii) notes that the prohibition on obstructions to the 
driver's field of view in paragraph (e)(1)(i) does not apply to vehicle 
safety technologies, as defined in Sec.  393.5, that are mounted on the 
interior of a windshield. The change to Sec.  393.60(e)(1)(ii) expands 
the area available for mounting vehicle safety technologies on the 
interior of a windshield. Devices with vehicle safety technologies may 
be mounted:
     Not more than 216 mm (8.5 inches) below the upper edge of 
the area swept by the windshield wipers;
     Not more than 175 mm (7 inches) above the lower edge of 
the area swept by the windshield wipers; and
     Outside the driver's sight lines to the road and highway 
signs and signals.
    The change will have no cost, but will result in an annualized cost 
savings from reduced application and exemption processing. The cost 
savings will be $10,903 at both 3 percent and 7 percent discount rates.

Wage Rates
    For this analysis, we calculated private sector wages using 2020 
wage data from the U.S. Bureau of Labor Statistics (BLS) Occupational 
Employment Statistics for the Management of Companies and Enterprises 
(North American Industry Classification System 551100). We used a 
median hourly wage for Standard Occupational Classification Code 11-
2021--Marketing Managers, which is $71.87.\1\
---------------------------------------------------------------------------

    \1\ https://www.bls.gov/oes/current/naics4_551100.htm#11-0000 
(last accessed Sept. 1, 2021).
---------------------------------------------------------------------------

    We added a load factor to the industry wages for Marketing Managers 
using December 2020 wage and total compensation data from the BLS 
Employer Costs for Employee Compensation (ECEC) survey, which accounts 
for employee benefits. This load factor represents the total benefits 
as a percentage of total salary.\2\ We multiplied the median hourly 
wage by the load factor to get the full loaded wage of $103.49.
---------------------------------------------------------------------------

    \2\ We calculate the load factor for wages by dividing total 
compensation by wages and salaries. For this analysis, we used BLS' 
ECEC/Management, professional, and related occupations. Using 
December 2020 data, we divided the total compensation amount of 
$61.72 by the wage and salary amount of $42.95 to get the load 
factor of 1.44 ($61.72 divided by $42.95). This data is found in 
table 9 of the ECEC Historical Listing. Available at https://www.bls.gov/web/ecec/ececqrtn.pdf (accessed Sept. 2, 2021)
---------------------------------------------------------------------------

    We utilized Federal Government employee wage rates based on the 
Office of Personnel Management (OPM) 2020 General Schedule (GS) pay for 
the DC-MD-VA-WV-PA locality for a GS-15 grade.\3\ Using OPM data, we 
generated an hourly wage for a GS-15 Step 1 grade as $68.38.\4\

    OMB publishes an object class analysis of the budget of the U.S. 
Government.\5\ The object class shows that, in 2020, DOT spent $6,602 
million in full-time permanent employee compensation and $2,590 million 
in civilian employee benefits. Based on this, FMCSA estimated a fringe 
benefit rate of 39.23 percent (2,590/6,602) for FMCSA personnel or 
$26.82 ($68.38 x 39.23 percent). The fully loaded hourly wage for a GS-
15 Step 1 is $95.20 ($68.38 + $26.82).

Costs
    Motor carriers, industry technological manufacturers, and drivers 
will not incur any new costs associated with this final rule. Adopting 
and using windshield-mounted technologies is purely optional. Those who 
install and use windshield-mounted technologies will experience no 
added burdens or costs as a result of this rule.
    In CMVs, drivers sit in an elevated position that greatly improves 
the forward visual field. When FMCSA previously granted exemptions, it 
found that doing so would likely achieve a level of safety equivalent 
to, or greater than, the level of safety achieved without the 
exemption. As described in the NPRM, since issuing the first temporary 
exemption from Sec.  393.60(e)(1) in 2009, FMCSA is unaware of any 
crashes that have been attributed to the location of such devices.
    The expanded location is expected to keep pace with technological 
advances and further aid in meeting the statutory requirements of the 
FAST Act. The expanded area is outside the driver's line of sight to 
the road, highway signs, and signals.
Cost Savings
    We anticipate that this final rule will generate cost savings to 
(1) motor carrier companies that file fewer exemption requests, and (2) 
the Federal government by reducing the volume of exemption requests to 
be reviewed and processed.
    Several manufacturers of windshield-mounted technologies have 
requested exemptions from FMCSA. We estimate that completing each 
exemption request takes about 2 hours of company time. FMCSA, on 
average, receives three exemption applications that are impacted by 
this rule per year. Table 2 provides the 10-year time horizon cost 
savings stream based on the yearly undiscounted $621 (rounded to the 
nearest whole dollar) cost savings to industry.\6\

    Federal government employees who possess the technical knowledge 
required to review windshield exemption applications are senior 
engineers and attorneys at the GS-15 grade. A final approval letter for 
an exemption is granted by the Associate Administrator at the Senior 
Executive Service level.\8\ We estimate the total time from initial 
exemption receipt to final approval to be 12 non-consecutive hours.

Benefits
    The Agency was unable to identify literature that quantified the 
benefits of increasing the allowable windshield area for the mounting 
of vehicle safety technologies. In the absence of such analyses, the 
Agency did not quantify benefits associated with the final rule, though 
it believes that the rule has the potential to improve the safety of 
CMV operations.12 13 The Agency also finds that CMVs 
outfitted with vehicle safety technologies under current exemptions do 
not present an increased safety risk compared to other CMVs.

Discussion of Alternatives
    When preparing this final rule, FMCSA considered two alternatives. 
In this section, we examine how the cost of the proposal would change 
with each alternative.
Alternative 1
    No Action.
    Applying a ``no action'' alternative, FMCSA would accept the status 
quo and not change the current exemption approval requirements. This 
alternative currently limits the windshield area in which new safety 
technologies can be mounted to not more than 100 mm (4 inches) below 
the upper edge of the area swept by the windshield wipers or not more 
than 175 mm (7 inches) above the lower edge of the area swept by the 
windshield wipers. This alternative does not favor innovation and 
technological growth, nor does it reduce the overall burden to industry 
of applying for, and to the Federal Government of reviewing, 
exemptions. This alternative would maintain the approximately $10,903 
(annualized, 7 percent discount rate) in annual costs associated with 
the overall exemption request and approval process.
Alternative 2
    Preferred Alternative--Revise 49 CFR 393.60 to expand the 
windshield area where vehicle safety technologies could be installed on 
CMVs and revise 49 CFR

[[Page 12603]]

393.5 to broaden the definition of vehicle safety technology.
    Applying this preferred alternative, FMCSA would increase the 
allowable windshield area for installation of vehicle safety 
technologies. This would lead to an estimated $10,705 in annual cost 
savings without any estimated cost increase or reduction in benefits, 
as this analysis shows.

B. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801-808), OIRA 
designated this rule as not a ``major rule,'' as defined by 5 U.S.C. 
804(2).\14\
---------------------------------------------------------------------------

    \14\ A ``major rule'' means any rule that OMB finds has resulted 
in or is likely to result in (a) an annual effect on the economy of 
$100 million or more; a major increase in costs or prices for 
consumers, individual industries, Federal agencies, State agencies, 
local government agencies, or geographic regions; or significant 
adverse effects on competition, employment, investment, 
productivity, innovation, or on the ability of United States-based 
enterprises to compete with foreign-based enterprises in domestic 
and export markets (5 U.S.C. 804(2)).
---------------------------------------------------------------------------

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.), as amended 
by the Small Business Regulatory Enforcement Fairness Act of 1996,\15\ 
requires Federal agencies to consider the effects of the regulatory 
action on small business and other small entities and to minimize any 
significant economic impact. The term ``small entities'' comprises 
small businesses and not-for-profit organizations that are 
independently owned and operated and are not dominant in their fields, 
and governmental jurisdictions with populations of less than 50,000 (5 
U.S.C. 601(6)). Accordingly, DOT policy requires an analysis of the 
impact of all regulations on small entities, and mandates that agencies 
strive to lessen any adverse effects on these businesses.
---------------------------------------------------------------------------

    \15\ Public Law 104-121, 110 Stat. 857, (Mar. 29, 1996).
---------------------------------------------------------------------------

    The Agency expects that this final rule will not have a significant 
economic impact on small entities. The final rule will result in cost 
savings to industry and the Federal government.
    FMCSA expects the average costs to manufacturers of windshield-
mounted equipment associated with avoiding the need for exemption 
applications will be reduced by $621 per year (annualized, 7 percent 
discount rate). We calculate that 100 percent of small equipment 
manufacturers impacted by this final rule will have a cost savings less 
than 1 percent of their annual revenue. No small governmental 
jurisdictions will be impacted by this final rule.
    Consequently, I certify that the final action will not have a 
significant economic impact on a substantial number of small entities. 
If you think that your business, organization, or governmental 
jurisdiction qualifies as a small entity and that this final rule would 
have a significant economic impact on it, please submit a comment to 
the docket at the address listed in the ADDRESSES section of this 
preamble. In your comment, explain why you think it qualifies and how 
and to what degree this final rule would economically affect it.

D. Assistance for Small Entities

    In accordance with section 213(a) of the Small Business Regulatory 
Enforcement Fairness Act of 1996,\16\ FMCSA wants to assist small 
entities in understanding this final rule so they can better evaluate 
its effects on themselves and participate in the rulemaking initiative. 
If the final rule will affect your small business, organization, or 
governmental jurisdiction and you have questions concerning its 
provisions or options for compliance, please consult the person listed 
under FOR FURTHER INFORMATION CONTACT.
---------------------------------------------------------------------------

    \16\ Public Law 104-121, 110 Stat. 857, (Mar. 29, 1996).
---------------------------------------------------------------------------

    Small businesses may send comments on the actions of Federal 
employees who enforce or otherwise determine compliance with Federal 
regulations to the Small Business Administration's Small Business and 
Agriculture Regulatory Enforcement Ombudsman and the Regional Small 
Business Regulatory Fairness Boards. The Ombudsman evaluates these 
actions annually and rates each agency's responsiveness to small 
business. If you wish to comment on actions by employees of FMCSA, call 
1-888-REG-FAIR (1-888-734-3247). DOT has a policy regarding the rights 
of small entities to regulatory enforcement fairness and an explicit 
policy against retaliation for exercising these rights.

E. Unfunded Mandates Reform Act of 1995

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) 
requires Federal agencies to assess the effects of their discretionary 
regulatory actions. The Act addresses actions that may result in the 
expenditure by a State, local, or Tribal government, in the aggregate, 
or by the private sector of $170 million (which is the value equivalent 
of $100 million in 1995, adjusted for inflation to 2020 levels) or more 
in any 1 year. Because this final rule will not result in such an 
expenditure, a written statement is not required. However, FMCSA does 
discuss the costs and benefits of this final rule in the preamble.

F. Paperwork Reduction Act

    This final rule contains no new information collection requirements 
under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). FMCSA 
notes that the burden associated with preparing an exemption request is 
not included in a currently approved information collection request 
(ICR), and the Agency is pursuing completion of that ICR outside of 
this rulemaking.

G. E.O. 13132 (Federalism)

    A rule has implications for federalism under section 1(a) of E.O. 
13132 if it has ``substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.'' FMCSA has determined that this rule would not have 
substantial direct costs on or for States, nor would it limit the 
policymaking discretion of States. Nothing in this document preempts 
any State law or regulation. Therefore, this rule does not have 
sufficient federalism implications to warrant the preparation of a 
Federalism Impact Statement.

H. Privacy

    The Consolidated Appropriations Act, 2005,\17\ requires the Agency 
to assess the privacy impact of a regulation that will affect the 
privacy of individuals. This final rule does not require the collection 
of personally identifiable information (PII). Because this final rule 
does not require the collection of PII, the Agency is not required to 
conduct a privacy impact assessment (PIA). Section 208 of the E-
Government Act of 2002 (44 U.S.C. 3501 note) requires Federal agencies 
to conduct a PIA for new or substantially changed technology that 
collects, maintains, or disseminates information in an identifiable 
form. No new or substantially changed technology will collect, 
maintain, or disseminate such information as a result of this rule. 
Accordingly, FMCSA has not conducted a PIA.
---------------------------------------------------------------------------

    \17\ Public Law 108-447, 118 Stat. 2809, 3268, note following 5 
U.S.C. 552a (Dec. 4, 2014).
---------------------------------------------------------------------------

    In addition, the Agency submitted a Privacy Threshold Assessment to 
evaluate the risks and effects the rulemaking might have on collecting, 
storing, and sharing personally identifiable information. The DOT 
Privacy Office has determined that this rulemaking does not create 
privacy risk.

I. E.O. 13175 (Indian Tribal Governments)

    This rule does not have Tribal implications under E.O. 13175, 
Consultation and Coordination with Indian Tribal Governments, because 
it does not have a substantial direct effect on one or more Indian 
Tribes, on the relationship between the Federal Government and Indian 
Tribes, or on the distribution of power and responsibilities between 
the Federal Government and Indian Tribes.

J. National Environmental Policy Act of 1969

    FMCSA analyzed this rule pursuant to the National Environmental 
Policy Act of 1969 (42 U.S.C. 4321 et seq.) and determined this action 
is categorically excluded from further analysis and documentation in an 
environmental assessment or environmental impact statement under FMCSA 
Order 5610.1 (69 FR 9680), Appendix 2, paragraph 6.bb. The Categorical 
Exclusion (CE) in paragraph 6.bb. addresses regulations concerning 
vehicle operation safety standards (e.g., regulations requiring: 
Certain motor carriers to use approved equipment which is required to 
be installed such as an ignition cut-off switch, or carried onboard, 
such as a fire extinguisher, and/or stricter blood alcohol 
concentration standards for drivers, etc.), equipment approval, and/or 
equipment carriage requirements (e.g., fire extinguishers and flares). 
The requirements in this rule are covered by this CE and the final 
action does not have any effect on the quality of the environment.
