Drivers of large trucks and other vehicles involved in truck crashes are 10 times more likely to be the cause of the crash than other factors, such as weather, road conditions, and vehicle performance, according to a new study released by the Federal Motor Carrier Safety Administration (FMCSA).

“This study makes it clear that we need to spend more time addressing driver behavior, as well as making sure trucks and buses are fit for the road,” said Annette Sandberg, FMCSA administrator.

The Large Truck Crash Causation Study was commissioned by FMCSA to review the causes of, and contributing factors to, crashes involving commercial motor vehicles. While previous data focused on specific crashes and/or individual causes of crashes, this study was the first nationwide examination of all pre-crash factors, FMCSA said.

FMCSA will conduct analysis to further examine driver factors such as use of prescription and over-the-counter drugs, speeding, fatigue, inattention, distractions, work environment, and unfamiliarity with the road.

This study, conducted with the help of the National Highway Traffic Safety Administration, investigated a national sample of fatal and injury crashes between April 2001 and December 2003 at 24 sites in 17 states. Each crash involved at least one large truck and resulted in at least one fatality or injury.

The total sample of 967 crashes included 1,127 large trucks, 959 non-truck motor vehicles, 251 fatalities, and 1,408 injuries. Action or inaction by the driver of either the truck or other vehicle was the critical reason for 88% of the crashes.

The American Trucking Associations (ATA) commended the study and agreed with FMCSA that “more data analysis is necessary” to reach additional conclusions about the reasons and factors for large-truck crashes.

The study database eventually will be available to the public. For copies of the report, access www.fmcsa.dot.gov/.
