Hours of Service Final Rule for Truck Drivers
The Hours of Service of Drivers Final Rule was published in the Federal Register on December 27, 2011. The effective date of the Final Rule was February 27, 2012, and the compliance date of remaining provisions was July 1, 2013.
NOTICE: The Consolidated and Further Continuing Appropriations Act of 2015 was enacted on December 16, 2014, suspending enforcement of requirements for use of the 34-hour restart, pending a study. Based on the findings from the CMV Driver Restart Study, the 34-hour restart rule in operational effect on June 30, 2013, is restored to full force and effect. The requirement for two off-duty periods of 1:00 a.m. to 5:00 a.m. in section 395.3(c) of the Agency’s hours-of-service rules will not be enforced, nor will the once-per-week limit on use of the restart in 395.3(d).

Hours of Service Live Question and Answer Session
The Federal Motor Carrier Safety Administration’s (FMCSA) hour-long Hours of Service (HOS) Question and Answer Session allowed participants the opportunity to submit HOS related questions and have them answered by FMCSA’s HOS subject matter experts Tom Yager, Chief of the Driver and Carrier Operations Division, and Peter Chandler, Lead Transportation Specialist in the Federal Motor Carrier Safety Administration Passenger Carrier Division.
The HOS Question and Answer session addressed the number hours that a commercial motor vehicle (CMV) driver may be on the road, the HOS exemptions, and the number of hours a CMV driver may be on duty before a required period of rest. In addition, the session addressed the permitted driving time based on a driver’s on-duty hours in a “work-week”.
