Drivers must hold their Missouri CDL credentials, first, before operating certain commercial vehicles, both inside and outside of the state. There are three CDL license classes in Montana. Each class refers to a category of vehicle. Depending on the type of cargo you are transporting, you may be required to add an endorsement to your license, as well.

Commercial drivers license fees are based on the class of license chosen, as well as the number of endorsements added. Before a CDL license can be issued, specific written and skills tests must be completed. Each class of license and endorsement requires separate testing. For example, truck driver license examinations differ from those required for a school bus endorsement or a hazmat endorsement.
