Title Evaluating the 2003 revised hours-of-service regulations for truck drivers: The impact of time-on-task on critical incident risk
Bibliographic information Mar. 2009, Vol.41, No.2, p.268-275. Illus. 16 ref.
Abstract In 2004, the Federal Motor Carrier Safety Administration implemented a revised set of regulations concerning the hours-of-service of commercial motor vehicle drivers. One central component of the revised regulations was a one-hour increase in allowable driving time, from 10 to 11h. The current study evaluated the impact of the additional driving-hour on critical incident risk. Data from over two million driving miles were analyzed. The frequencies of critical incidents for each hour were identified and odds ratios determined. Analyses found an elevated risk in the 1st driving-hour, but no consistent significant difference between hours 2 through 11. The results of this study do not support the hypothesis that there is an increased risk resulting from driving an additional hour.
