Full Text

No person shall operate a commercial motor vehicle unless the person holds a valid commercial driver's license (CDL) with the proper class and endorsements. CDL classes are based on vehicle type: Class A for combination vehicles over 26,001 lbs, Class B for single vehicles over 26,001 lbs, and Class C for vehicles designed to transport 16 or more passengers or hazardous materials.

Applicants must pass knowledge and skills tests, meet medical standards, and maintain a clean driving record. States must disqualify drivers for serious traffic violations, and employers must verify CDL validity before hiring.
