Are Canadian and Mexican-domiciled carriers operating in the U.S. subject to Part 382?
['Drug and Alcohol Testing - DOT']

- Only drivers entering U.S. commerce with CMVs are subject to DOT drug and alcohol testing rules.
Department of Transportation (DOT) drug and alcohol testing under the Federal Motor Carrier Safety Administration (FMCSA) applies to Canadian and Mexican-domiciled carriers that send trucks and buses into the United States that require a license equivalent to the U.S. commercial driver’s license (CDL).
But not all drivers from these carriers are subject to DOT drug and alcohol testing rules, only those entering U.S. commerce with these commercial motor vehicles (CMVs). If the carriers have drivers that remain solely in Canada or Mexico, these drivers do not qualify for DOT drug and alcohol testing, even though employed by a DOT-regulated carrier.
