When were carriers and drivers allowed or required to comply wit the new hours-of-service rules?
Carriers and drivers were required to operate under the former rules through January 3, 2004. That allowed adequate time for the Federal Motor Carrier Safety Administration (FMCSA), regulated industry, and the enforcement community to be trained and make any systems changes required by the new rules. Compliance with the new rules was required starting January 4, 2004.
