Large truck drivers killed in fatal crashes rarely have high blood alcohol concentrations (BACs). For example, 4% of fatally injured large truck drivers in 2017 had BACs at or above 0.08%, down from 17% in 1982. For comparison, 29% of fatally injured passenger vehicle drivers in 2017 had BACs at or above 0.08%, down from 51% in 1982.
By law, commercial motor vehicle drivers must use safety belts, according to Section 392.16 of the Federal Motor Carrier Safety Regulations. In 2017, there was a 0.1 percentage point decrease in the number of truck drivers in fatal crashes who were not wearing a safety belt.
