Large trucks | 2013

Most deaths in large truck crashes are passenger vehicle occupants. The main problem is the vulnerability of people traveling in smaller vehicles. Trucks often weigh 20-30 times as much as passenger cars and are taller with greater ground clearance, which can result in smaller vehicles underriding trucks in crashes.

Truck braking capability can be a factor in truck crashes. Loaded tractor-trailers take 20-40 percent farther than cars to stop, and the discrepancy is greater on wet and slippery roads or with poorly maintained brakes. Truck driver fatigue also is a known crash risk. Drivers of large trucks are allowed by federal hours-of-service regulations to drive up to 11 hours at a stretch and up to 77 hours over a seven-day period. Surveys indicate that many drivers violate the regulations and work longer than permitted. McCartt, A.T.; Hellinga L.A.; and Solomon, M.G. 2008. Work schedules of long-distance truck drivers before and after 2004 hours-of-service rule change. Traffic Injury Prevention 9:201-10.

The following facts are based on analysis of data from the U.S. Department of Transportation's Fatality Analysis Reporting System (FARS).

Trends

A total of 3,602 people died in large truck crashes in 2013. Sixteen percent of these deaths were truck occupants, 67 percent were occupants of cars and other passenger vehicles, and 15 percent were pedestrians, bicyclists or motorcyclists. The number of people who died in large truck crashes was 14 percent higher in 2013 than in 2009, when it was lower than at any year since the collection of fatal crash data began in 1975.  The number of truck occupants who died was 31 percent higher than in 2009. Since 1979, when deaths in large truck crashes were at an all time high, there has been a greater percentage decline among occupants of large trucks (57 percent) than among occupants of passenger vehicles (43 percent).

Comparison of large truck crashes and passenger vehicle crashes

Forty-nine percent of large truck occupant deaths in 2013 occurred in crashes in which their vehicles rolled over. This was similar to the percentage of SUV occupant deaths (50 percent) and pickup occupant deaths (45 percent) that occurred in rollover crashes and much higher than the percentage of occupant deaths in cars (24 percent) involving rollovers.

In contrast with passenger vehicle drivers, large truck drivers killed in fatal crashes rarely have high blood alcohol concentrations (BACs). Truck drivers are subject to strict government regulations concerning drinking and driving. Four percent of fatally injured large truck drivers in 2013 had BACs at or above 0.08 percent, down from 17 percent in 1982. For comparison, 33 percent of fatally injured passenger vehicle drivers in 2013 had BACs at or above 0.08 percent, down from 51 percent in 1982.
