Do you have to retake the commercial drivers license exam when renewing your license?
In most jurisdictions, you do not have to retake the entire commercial drivers license (CDL) exam when renewing your license. However, you may be required to take a vision test, physical examination, and knowledge test on specific regulations and safety information. The frequency of these additional tests varies from state to state and depends on your CDL license class. Some states might also require a road skills test periodically. It's best to check with your local Department of Motor Vehicles or the equivalent agency in your region for exact renewal requirements and any potential changes before your license expiration date.
