The objective of this project was to determine whether changes to the hours-of-service (HOS) rules have had any impact on commercial motor vehicle (CMV) safety, carrier productivity and cost, and the U.S. highway system. The Agency was primarily interested in examining data before and after the HOS rule changes and the impact of the rule changes on safety, driver schedules and productivity, cost of trucking, and measures of highway system performance. A report detailing study findings was submitted to the Agency for review. |
