Hours of Service of Drivers

Summary: FMCSA adopts as final the provisions of the Agency's December 17, 2007, interim final rule concerning hours of service (HOS) for commercial motor vehicle (CMV) drivers. This final rule allows CMV drivers to continue to drive up to 11 hours within a 14-hour, non- extendable window from the start of the workday, following at least 10 consecutive hours off duty (11-hour rule). The rule also allows motor carriers and drivers to continue to restart calculations of the weekly on-duty limits after the driver has at least 34 consecutive hours off duty (34-hour restart).
