SUPPLEMENTARY INFORMATION: Safety Standards 223 (49 CFR 571.223) and
224 (49 CFR 571.224) require underride guards meeting a strength test
on trailers with a GVWR of 10,000 pounds or greater manufactured on or
after January 24, 1998. Safety Standard 224 defines the size
requirements for the guards, while Safety Standard 223 describes
strength testing and energy absorption requirements for DOT-compliant
guards. This report is a statistical analysis of crash data aimed at
determining the effectiveness of standard-compliant underride guards at
preventing fatalities and serious injuries in crashes where a passenger
vehicle impacts the rear of a
[[Page 68664]]
tractor-trailer. The primary findings are the following:
Data from Florida and North Carolina showed decreases in
fatalities and serious injuries to passenger vehicle occupants when
rear-ending a tractor-trailer subsequent to the implementation of
Safety Standards 223 and 224. However, the observed decreases are not
statistically significant at the 0.05 level, possibly due to the small
sample sizes of the data.
Using supplemental data collection from North Carolina, it
is shown that passenger vehicle passenger compartment intrusion is more
apt to occur when the corner of the trailer is impacted, rather than
the center of the trailer. This result is statistically significant at
the 0.01 level.
It is not possible to establish a nationwide downward
trend in fatalities when a passenger vehicle rear-ends a tractor-
trailer--neither in terms of total number of fatalities, percentage of
fatalities in rear impacts relative to other passenger vehicle
fatalities involved in tractor-trailer accidents, nor number of fatal
crashes per 1,000 total crashes. The Fatality Accident Reporting System
does not list the model year of the trailer.
In April 2009, NHTSA issued An In-Service Analysis of Maintenance
and Repair Expenses for the Anti-Lock Brake System and Underride Guard
for Tractors and Trailers (74 FR 18803).
