Commercial learner's permit
Commercial learner's permit (CLP) means a permit issued to an individual by a State or other jurisdiction of domicile, in accordance with the standards contained in this part, which, when carried with a valid driver's license issued by the same State or jurisdiction, authorizes the individual to operate a class of a commercial motor vehicle when accompanied by a holder of a valid CDL for purposes of behind-the-wheel training. When issued to a CDL holder, a CLP serves as authorization for accompanied behind-the-wheel training in a CMV for which the holder's current CDL is not valid.
