FMCSA prepared a Final Environmental Assessment for the 2011 Hours-of-Service (HOS) Final Rule that makes changes to the HOS regulations issued in 2008. The HOS regulations apply to operators of commercial motor vehicles (CMVs) and CMV drivers engaged in interstate commerce, and address requirements for driving, duty, and off-duty time; a recovery period; sleeper berth; and requirements for short-haul drivers. FMCSA finds that the analysis warrants a Finding of No Significant Impact and that an Environmental Impact Statement is not needed.
