CDL Classifications, Endorsements, Restrictions & Exemptions

Three classes of Commercial Driver Licenses are available. These licenses come with specific endorsements and restrictions. Also, some vehicles are exempt from CDL requirements.

CDL Classifications

Table 28: CDL Classifications

AAny combination of vehicles with a Gross Combination Weight Rating (GCWR) exceeding 26,000 pounds, provided the vehicle being towed has a Gross Vehicle Weight Rating (GVWR) exceeding 10,000 pounds
BAny single vehicle with a GVWR exceeding 26,000 pounds, or any such vehicle towing a vehicle not exceeding 10,000 pounds
CAny single vehicle or combination of vehicles that does not meet the definition of Class A or Class B, but is either required to be placarded for hazardous materials or designed to transport 16 or more passengers, including the driver

A CDL of any class also allows operators to drive their personal vehicle; no other driver license is needed. It does not allow them to drive a motorcycle unless they have a Class 3 license along with the Class A, B, or C CDL. For example, A3 allows operators to drive a Class A commercial vehicle and their personal vehicle, including a motorcycle.
