CDL License

To get a CDL license, you must pass a knowledge (written) test and a skills (road) test to ensure that you have the minimum knowledge and skill required to drive a commercial motor vehicle.

You will have to pass one or more knowledge tests, depending on the class of license and the endorsements that you need. Each test will be scored separately. The passing score is 80% for all commercial knowledge tests.
