(2) Except as provided in paragraph (b) of this section, no person may legally operate a CMV unless such person possesses a CDL which meets the standards contained in subpart J of this part, issued by his/her State or jurisdiction of domicile. (b) Exception. (1) If a CMV operator is not domiciled in a foreign jurisdiction which the Administrator has determined tests drivers and issues CDLs in accordance with, or under standards similar to, the standards contained in subparts F, G, and H of this part, the person may obtain a Nonresident CDL from a State which does comply with the testing and licensing standards contained in such subparts F, G, and H of this part.1 1 Effective December 29, 1988, the Administrator determined that commercial drivers' licensees issued by Canadian Provinces and Territories in conformity with the Canadian National Safety Code are in accordance with the standards of this part.

(c) Learner's permit. State learners' permits, issued for limited time periods according to State requirements, shall be considered valid commercial drivers' licenses for purposes of behind-the-wheel training on public roads or highways, if the following minimum conditions are met: (1) The learner's permit holder is at all times accompanied by the holder of a valid CDL; (2) He/she either holds a valid automobile driver's license, or has passed such vision, sign/symbol, and knowledge tests as the State issuing the learner's permit ordinarily administers to applicants for automotive drivers' licenses; and (3) He/she does not operate a commercial motor vehicle transporting hazardous materials as defined in §383.5.
