Montana CDL License Requirements

To begin a career as a truck driver in Montana, you must first obtain a Montana commercial driver's license (CDL). The State of Montana uses the following criteria to determine whether or not a CDL is required to drive a commercial vehicle.

  • Class A: Combination vehicles with a total weight of 26,001 pounds or above, where the towed vehicle(s) is over 10,000 pounds.
  • Class B: Vehicles weighing 26,001 pounds or more, where the towed vehicle(s) is less than 10,000 pounds.
  • Class C: Vehicles weighing under 26,001 pounds, used for transporting sixteen or more passengers or hauling hazardous materials.

To obtain a Montana CDL, you must be at least 18 years old, have a valid Montana driver's license, pass a vision exam and obtain a medical certificate. The U.S. Department of Transportation (USDOT) regulates the transportation of cargo between states. USDOT requires all drivers who transport materials across state lines to be at least 21 years old. Applicants must then pass both a written knowledge exam and an on-road driving test. For the driving test, applicants must test in the class of vehicle for which they would like to obtain a CDL license.

Depending on the type of truck you wish to drive or the cargo you wish transport, additional endorsement may be required. Endorsements are needed to drive a truck with air brakes, a tanker truck, a school bus or a truck with double/triple trailers. Endorsements are also needed to transport passengers or to haul hazardous materials. To transport hazardous materials (also referred to as a Hazmat endorsement), a Transportation Security Administration (TSA) background check is required. Truck driving schools will provide the training and education needed to pass the Montana CDL requirements.
