CDL Classes (A, B, C) and Vehicle Requirements

The entry defines the three Federal Motor Carrier Safety Administration CDL classes-Class A for combination vehicles with a gross combination weight rating of 26 000 lb or more, Class B for single vehicles of 26 000 lb or more, and Class C for vehicles that transport 16 or more passengers or hazardous materials but fall below the other weight thresholds. It specifies the vehicle weight, passenger capacity, and hazardous-material criteria that determine which class is required, along with the basic qualifications and endorsements needed for each.
