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.

CDL Requirements in Missouri

All of Missouri’s CDL license requirements must be met before you can operate a commercial vehicle on public roads. The CDL requirements for carrying hazardous materials follow stricter guidelines.

Drivers applying for a hazmat endorsement must complete federal background checks before completing the application process.

CDL requirements state that drivers must hold their valid Missouri driver’s licenses to qualify for a CDL. Applicants must be at least 18 years old to apply for the intrastate license, and at least 21 years old to apply for the interstate license.
