If a CMV is equipped with air brakes, then the driver must have a CDL with an air brake endorsement. This endorsement requires additional training and testing beyond what is required for a regular CDL. The training and testing cover topics such as the operation and maintenance of air brake systems, as well as the safe driving practices that are necessary to operate a CMV with air brakes.
In some jurisdictions, there may be exceptions to the air brake endorsement requirement for certain types of CMVs. For example, some jurisdictions may exempt vehicles with a GVWR of less than 26,001 pounds from the air brake endorsement requirement. However, it is important to note that these exceptions are not universal, so it is always best to check with the local licensing authority to determine the specific requirements for operating a CMV in your jurisdiction.
In addition to the air brake endorsement, there may be other endorsements or restrictions that apply to your CDL, depending on the type of CMV you are operating and the jurisdiction in which you are driving. For example, you may need to have a tanker endorsement to transport hazardous materials, or a passenger endorsement to transport passengers. It is important to be aware of all of the endorsements and restrictions that apply to your CDL, and to ensure that you are properly licensed and qualified to operate the CMV you are driving.
