FMCSA studying drivers’ schedules vs. performance

Study will analyze hours-of-service and crash data

Posted October 25, 2018

The Federal Motor Carrier Safety Administration (FMCSA) issued an information collection request for a study analyzing how commercial motor vehicle (CMV) drivers’ schedules impact overall driver performance and safety.

The objective of the study, titled “Crash Risk by Commercial Motor Vehicle Driver Schedules,” is to collect hours-of-service (HOS) and crash data to analyze how HOS provisions are being used and the effect of driver schedules on crash risks.

FMCSA is collecting the data to answer the following research questions:

  • What is the relative crash risk by hour of driving?
  • What is the relative crash risk by hour of driving per week?
  • What is the relative crash risk of driving breaks (comparison of crash rates for drivers who take no breaks compared to drivers who take one and two 30-minute breaks per day)?
  • What is the relative crash risk as a function of recovery periods that contain one period between 1 a.m. and 5 a.m. compared to two periods between 1 a.m. and 5 a.m. and as a function of weekly working hours before and after a 34-hour restart?
  • How are each of the HOS provisions being used?

Comments will be accepted through December 23, 2018. Comments can be submitted by Federal Docket Management System FMCSA-2018-0279 through the Federal eRulemaking Portal. Follow online instructions for submitting comments.
