Commercial Driver License (Class A, B, or C)

What is a Commercial License?

Operators of larger and more complex vehicles will need to apply for a Commercial Driver License (CDL). These licenses include Class A, B, and C depending upon the Gross Vehicle Weight Rating (GVWR), Gross Combination Weight Rating (GCWR), and what is being transported. In general, state law defines a commercial motor vehicle (CMV) as any vehicle or combination of vehicles weighing more than 26,000 pounds. If hazardous materials are transported, or if the vehicle is designed to transport more than fifteen (15) passengers including the driver, or if the vehicle is used as a school bus, a CDL would also be required, regardless of the weight of the vehicle. Drivers who need a CDL should obtain the Commercial Driver License Manual which contains detailed information necessary to prepare for the tests. These manuals are available at all driver license stations.

The Temporary Driver License is not available to cover any type of commercial motor vehicle. An applicant for a CDL must be able to provide proof of U.S. Citizenship or Lawful Permanent Resident status in order to qualify for issuance of a Tennessee CDL.

See the Commercial Motor Vehicles Guide for more information.

NOTE : If a person holds a valid commercial driver license (Class A, B, or C license), this license is also valid for operating a Class D vehicle. No separate Class D license is required.

What class license to I need?

Commercial licenses include Class A, B, and C depending upon the Gross Vehicle Weight Rating (GVWR), Gross Combination Weight Rating (GCWR), and what is being transported.

Some drivers may require an A/57 license.  This license applies to drivers who do not require a class A license, but who haul an excess of 10,001 pounds or more.  Examples are: F450 pick-up truck hauling a 10,001 or more pound trailer, an electric department truck hauling a 10,000 pound forklift on a flatbed trailer, etc.
