Commercial Driver License

License Information

Classes of Licenses

Commercial driver licenses (CDLs) are divided into three classes: Class A, B and C. Please refer to Section 1 of the CDL manual for more information on deciding what class of CDL you may need.

  • Class A CDL is required to operate a combination vehicle (truck and trailer) if the gross combined weight rating (GCWR) is 26,001 or more pounds when the gross vehicle weight rating (GVWR) of the trailer, which is added to the GVWR of the power unit (the truck), is 10,001 pounds or more.
  • Class B CDL is required to operate any vehicle with a GVWR of 26,001 pounds or more. A trailer may be towed if the GVWR of the trailer is 10,000 pounds or fewer.
  • Class C CDL is required to operate any vehicle with a GVWR of 26,000 pounds or fewer if the vehicle is required to be placarded to transport hazardous materials or if the vehicle transports 16 or more passengers, including the driver. An applicant must also have a passenger (P) or hazardous materials endorsement (HME) to obtain a Class C CDL.
