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

Important Information

In December 2008, the Tennessee Department of Safety sent notices to each State's Commercial Driver License Coordinator informing them that our department has information indicating that a third party testing company did not administer the skills tests in accordance with the Rules of the Tennessee Department of Safety's Driver Services Division, Chapter 1340-1-13-.22, paragraph 5(b) 10, or Federal Regulation 383.75(a)(2)(iii)(1993).

With the assistance of the Federal Motor Carrier Safety Administration (FMCSA) Nashville Division, the department was able to locate the current address for each driver who tested for their CDL skills Test with this third party testing company. The department then suggested that each State's CDL Coordinator require drivers to submit to a re-test in order to maintain their current Commercial Driver License. Those drivers that currently reside in Tennessee will be required by our department to submit to a complete retest which consists of both Knowledge and skills tests.

Tennessee did not indicate that the commercial license issued to CDL holders who tested with the third party testing company were fraudulent or invalid, but indicated that the skills tests were not administered properly as outlined in state and federal regulations for third party testing. For those drivers that are no longer Tennessee residents, they must comply with the state that currently has jurisdiction of their license. That state has sole discretion as to how and if they are going to re-test their drivers.

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 do 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.
