CDL classifications are available in A, B or C types, with various endorsements for specific equipment and cargo available for each. Endorsements may require additional written knowledge tests, and usually a skills test. The classification rating generally certifies a licensee for a specific gross weight range and type of cargo to be driven. Endorsements add specialized capabilities including transporting passengers, driving school buses, operating farm equipment, towing tankers or hauling hazardous material, which also requires fingerprinting and a background check.
Many states also offer downloadable practice tests for study, along with study guides. A knowledge exam must be taken in order to receive a learner's permit allowing the holder to drive with a CDL holder present.

The medical certification generally requires submission by an approved medical service provider, after a specified examination. Identification requirements typically include proof of citizenship, such as a birth certificate or valid U.S. Passport, as well as a verifiable Social Security number and residence.Learn more about DMV & Records
