The type of brakes used in a vehicle does not determine whether or not the vehicle requires a CDL.
A commercial use vehicle requires a CDL when:
- It is a single vehicle or combination vehicle with a Gross Vehicle Weight Rating or Gross Combination Weight Rating of more than 26,000 lbs.
- It is transporting quantities of hazardous materials which requires the display of hazmat placards, regardless of the vehicle's weight rating.
- It is a bus designed to transport more than 15 persons (including the driver), regardless of the vehicle's weight rating.
If your vehicle matches any of the above criteria, then you need the appropriate class of CDL and you will need to take the written test for air brakes, as well as conduct your road test in an air-brake equipped vehicle. Otherwise, you will receive a restriction on your CDL which prohibits you from operating a commercial vehicle equipped with air brakes or air-over-hydraulic brakes.
If your vehicle does not meet any of the above criteria, then a CDL is not required.
