Study on Commercial Motor Vehicle (CMV) Driver Commuting (FAST Act, Section 5515)


To conduct a study on the effects of excessive commuting on safety and CMV driver fatigue.


Section 5515 of the Fixing America’s Surface Transportation Act, 2015 (FAST Act) directs the Administrator of the Federal Motor Carrier Safety Administration (FMCSA) to “conduct a study on the safety effects of motor carrier operator commutes exceeding 150 minutes.”


The study team will analyze relevant information from the American Community Survey regarding commuting times to best determine: the prevalence of excessive driver commuting in the CMV industry, including the number and percentage of drivers who commute; distances traveled; time zones crossed; time spent commuting; and methods of transportation used. The study team will conduct a literature review on the safety impacts of long work hours and consult with the National Institute of Occupational Safety and Health on the research they have conducted regarding driver work hours, commuting, and the impact of commuting on driver fatigue and safety. The study team will gather carrier data regarding the practices and policies carriers use to reduce commuting times and improve safety.
