The mission of the Federal Motor Carrier Safety Administration (FMCSA)
is to promote the safe operation of commercial vehicles on our Nations
highways. Of all the people killed in motor vehicle crashes in 2004, 12%
(5,190) died in crashes that involved a large truck. Another 116,000 people
were injured in crashes involving large trucks. Only about 15% of those
killed and 23% of those injured were occupants of large trucks.
Trends
-
Fatal Crashes.
From 1994 to 2004, the number of large trucks involved in
fatal crashes increased from 4,644 to 4,862 up 5%. The number of large trucks
in fatal crashes per 100 million vehicle miles traveled declined in these
years from 2.7 to 2.2 down 19%. The same rate for passenger vehicles fell
from 2.2 to 1.8down 18%.
Vehicles Involved in Fatal Crashes per 100 Million Vehicle Miles Traveled
-
Injury Crashes. From 1994 to 2004, the number of large trucks involved
in injury crashes per 100 million vehicle miles traveled declined by 32%,
while the rate for passenger vehicles dropped by 30%.

Vehicles
-
In 2004, large trucks drove 8% of all vehicle miles traveled and made up
3% of all registered vehicles in the United States. In motor vehicle crashes,
large trucks represented:
8% of vehicles in fatal crashes
3% of vehicles in injury crashes
4% of vehicles in property-damage-only
crashes.
-
Truck tractors pulling semi-trailers accounted for 63% of the trucks involved
in fatal crashes and about 47% of the trucks involved in nonfatal crashes.
-
Doubles (truck tractors pulling a semi-trailer and a full trailer) were
only 3% of trucks involved in both fatal and nonfatal crashes, and triples
(tractors pulling three trailers) accounted for less than 0.5% of all trucks
involved.
-
Only 5% of trucks involved in fatal crashes and 2% of trucks involved in
nonfatal crashes were carrying hazardous materials (HM). HM was released
from the cargo compartment in 21% of these crashes.
Drivers
-
Only 1% of the drivers of large trucks involved in fatal crashes in 2004
were legally intoxicated (blood alcohol content of 0.08 grams per deciliter
or higher), as compared with 22% of both passenger car drivers and light truck
drivers in fatal crashes. Only 2% of the drivers of large trucks involved
in fatal crashes had any alcohol in their bloodstream.
Percentage of Driver Alcohol Use in Fatal Crashes, 2004
-
Seventy-eight percent of the drivers of large trucks involved in fatal
crashes were reported by police as wearing their safety belts, compared
with 59% of passenger vehicle drivers involved in fatal crashes.
-
In fatal crashes involving large trucks, crash-related factors were cited
for 39% of the truck drivers. In comparison, crash- related factors were
noted for 67% of passenger vehicle drivers involved in fatal crashes. Some
of the most common factors cited for drivers of large trucks and drivers
of passenger vehicles were the same: driving too fast, running off the
road or out of the traffic lane, and failure to yield the right of way.
Crash Environment
-
Speeding (exceeding the speed limit or driving too fast for conditions)
was a factor in 23% of the fatal crashes involving a large truck, compared
with 32% of all fatal crashes.
-
No adverse weather conditions were reported for 84% of the fatal crashes
and for 86% of the nonfatal crashes involving large trucks in 2004. Rain
was the most common adverse weather condition.
-
Two-thirds (67%) of the fatal crashes involving large trucksand nearly
four-fifths (79%) of the nonfatal crashesoccurred during the day.
-
The vast majority of the fatal crashes involving large trucks (85%) and
of the nonfatal crashes (88%) occurred on Monday through Friday.
-
For 77% of the fatal crashes and for 70% of the nonfatal crashes involving
large trucks, the first harmful event was a collision with another vehicle
in transport.
-
Rollover was the first harmful event for only 4% of the fatal crashes and
only 3% of the nonfatal crashes involving large trucks.
-
Almost one-quarter (24%) of fatal crashes that took place in work zonesareas
of construction, maintenance, or utility activityinvolved a large truck.
