(a) General rule. (1) No person shall operate a CMV unless such person has taken and passed knowledge and driving skills tests for a CLP or CDL that meet the Federal standards contained in subparts F, G, and H of this part for the CMV that person operates or expects to operate.

(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 that 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, 1 the person may obtain a Non-domiciled CLP or Non-domiciled CDL from a State that does comply with the testing and licensing standards contained in such subparts F, G, and H of this part, so long as that person meets the requirements of § 383.71(f).

1 Effective December 29, 1988, the Administrator determined that commercial driver's licenses issued by Canadian Provinces and Territories in conformity with the Canadian National Safety Code are in accordance with the standards of this part. Effective November 21, 1991, and as amended on January 19, 2017, the Administrator determined that the new Licencias Federales de Conductor issued by the United Mexican States are in accordance with the standards of this part. Therefore, under the single license provision of § 383.21, a driver holding a commercial driver's license issued under the Canadian National Safety Code or a new Licencia Federal de Conductor issued by Mexico is prohibited from obtaining a non-domiciled CDL, or any other type of driver's license, from a State or other jurisdiction in the United States.

(2) If an individual is domiciled in a State while that State is prohibited from issuing CDLs in accordance with § 384.405 of this subchapter, that individual is eligible to obtain a Non-domiciled CLP or Non-domiciled CDL from any State that elects to issue a Non-domiciled CDL and which complies with the testing and licensing standards contained in subparts F, G, and H of this part, so long as that person meets the requirements of § 383.71(f).

(3) If an individual possesses a CLP, as defined in § 383.5, the individual is authorized to operate a class of CMV as provided by the CLP in accordance with § 383.25.
