On August, 25, 2005, FMCSA published a final HOS rule (“2005 rule”) (70 FR 49978). On July 24, 2007, the DC Circuit Court vacated the 11-hour driving time and 34-hour restart provisions of the 2005 rule (Owner-Operator Independent Drivers Association, Inc. v. Federal Motor Carrier Safety Administration, 494 F.3d 188 (DC Cir. 2007)). In response to the DC Circuit Court decision, FMCSA published an interim final rule (IFR) on December 17, 2007 (72 FR 71247) that reinstated the two provisions vacated by the Court and sought further comments on those provisions.
