Alabama (CDL) Commercial Driver License

Alabama adopted the Federal Commercial Motor Vehicle Safety Act of 1986, and is part of a nationally uniform system of classifying, testing, and licensing commercial vehicle drivers.

If you drive a commercial vehicle that falls into one of the following classifications, you must secure an Alabama Commercial Driver License (CDL).

CLASS A Alabama CDL - This classification applies only to "combination" vehicles with a Gross Combination Weight Rating (GCWR) exceeding 26,000 pounds, provided the Gross Vehicle Weight Rating (GVWR) of the vehicle being towed exceeds 10,000 pounds. The holder of a Class A license, which includes any appropriate endorsements, may operate all vehicles included in Class B, C, and D

CLASS B Alabama CDL - This class includes single or combination vehicles where the GVWR of the single vehicle exceeds 26,000 pounds. The vehicle in tow must not exceed 10,000 pounds. Class B licensees, with appropriate endorsements, may drive all vehicles in Class C or D.

CLASS C Alabama CDL - Vehicles designed to transport 16 or more passengers, including the driver, and vehicles placarded for hazardous materials, that do not meet the criteria for Class A or B above fall under this classification and may drive all vehicles in Class D.

Alabama CDL Endorsements are required for double/triple trailers, tanker vehicles, passenger vehicles and vehicles placarded for hazardous materials.

Commercial Drivers Manuals and information are available at your local driver license office.
