December 7, 2009 MCSAC Presentation1 Commercial Motor Vehicle Drivers’ Hours of Service Background Information Tom Yager Chief, FMCSA Driver and Carrier Operations Division

December 7, 2009 MCSAC Presentation2 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.

December 7, 2009 MCSAC Presentation3 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.…”

December 7, 2009 MCSAC Presentation4 Background Little fundamental change in commercial motor vehicle (CMV) hours-of-service (HOS) regulations from 1937 to 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).

December 7, 2009 MCSAC Presentation5 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.
