Harmonizing Schedule I Drug Requirements

Summary: The Federal Motor Carrier Safety Administration (FMCSA) proposes to amend the physical qualifications for drivers and the instructions for the medical examination report to clarify that drivers may not use Schedule I drugs and be qualified to drive commercial motor vehicles under any circumstances. The proposal also harmonizes FMCSA's provisions regarding pre-employment and return-to-duty test refusals with corresponding Department of Transportation (DOT)-wide provisions. Finally, the proposal corrects inaccurate uses of the term ``actual knowledge.''
