How to Get CDL Endorsements


Each state has a slightly different process when it comes to CDL endorsements, but most have the same testing and endorsement requirements.

To apply, provide your CDL application and the required documentation to your local DMV. On your application, you can indicate which endorsements you wish to earn. In addition, a written and driving skills test will be required.

Driving endorsement exams typically take 20-30 questions. A fee must be paid for each test. Your CDL endorsement test is available whenever you are ready at your local DMV.
