Important notice: Please see the new Hours-of-Service page for important details concerning rule changes effective October 1, 2005, including changes to the sleeper berth and short-haul provisions.

The Federal Motor Carrier Safety Administration is currently updating and revising its regulatory guidance to Part 395 of the FMCSRs to (1) bring items into conformance with the provisions of the new hours-of-service regulations, (2) to provide additional guidance concerning the application of the new regulations. All prior interpretations and regulatory guidance of Part 395 of the FMCSRs, as well as FMCSA and FHWA memoranda and letters concerning Part 395, may no longer be relied upon as authoritative insofar as they are inconsistent with the final rule published April 28, 2003 and the Technical Amendments published September 30, 2003. Please refer to the "Frequently Asked Questions" posted at this site for official guidance. However, previous guidance on sections not amended by the final rule and Technical Amendments remain valid.
