Commercial Motor Vehicle Drivers’Hours of Service Background Information Tom Yager Chief, FMCSA Driver and Carrier Operations Division MCSAC Presentation
Background • First Hours of Service (HOS) Rules • Interstate Commerce Commission, No. MC-2, 1937 • Issued first eight HOS rules. • Many issues and discussions similar to today. • By 1939, revisions started due to various objections. MCSAC Presentation
Background From ICC 1937 Deliberations: • “For some time we have had under serious consideration the advisability of having a comprehensive, scientific study made of the causes and effects of driver fatigue…. We have concluded that it would be wise to have such a study made.…” MCSAC Presentation
Background • Little fundamental change in commercial motor vehicle (CMV) hours-of-service (HOS) regulations from 1937 to 2004. • 1995 ICC Termination Act required the FHWA/OMC [now FMCSA] to address fatigue-related motor carrier safety issues. • Major revisions made in 2003 Final Rule (effective in 2004). MCSAC Presentation
Background • After a DC Circuit case, the 2005 Final Rule re-established the 2003 revisions (with a change in sleeper-berth provisions). • After a DC Circuit case, the 2007 IFR and 2008 Final Rule made no changes in regulatory language. Therefore, most current provisions (except sleeper-berth) have been in operation for nearly 6 years. MCSAC Presentation
