Are previous interpretations and guidance regarding hours-of-service still valid?
The FMCSA is currently updating and revising its regulatory guidance to Part 395 of the Federal Motor Carrier Safety Regulations (FMCSRs) to conform to the provisions of the new hours-of-service regulations, and to provide additional guidance concerning the application of the new regulations. All prior interpretations and regulatory guidance relating to 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 to the extent they are inconsistent with the final rule published April 28, 2003 and the Technical Amendments published September 30, 2003. All interpretations and guidance for Parts other than Part 395 remain valid.
