A career in trucking begins with obtaining your CDL (Commercial Driver’s License). In order to do so, you will be required to pass a series of written CDL tests to receive the proper endorsements, based on what type of trucking career you are pursuing.

Don’t waste your time or money by failing the written tests for your CDL permit.
