Note that the term “combination vehicle” means:
- a towed vehicle, like a trailer, and
- a power unit, or the vehicle doing the towing
Single, non-combination vehicles
Weight 26,001+ pounds = Class B license
If the single vehicle has a Gross Vehicle Weight (GVW) or Gross Vehicle Weight Rating (GVWR) of 26,001 pounds or more, the operator needs a Class B license.
Combination vehicles
Trailer 10,001+ pounds AND combination 26,001+ pounds = Class A license
If the trailer has a Gross Vehicle Weight (GVW) or Gross Vehicle Weight Rating (GVWR) of 10,001 pounds or more and the Gross Combination Weight Rating (GCWR) is 26,001 pounds or more, a Class A license is needed.
The GCWR is the greater of:
- The value specified by the manufacturer of the power unit, if the value is displayed on the Federal Motor Vehicle Safety Standard certification label required by the National Highway Traffic Safety Administration, or
- The sum of the Gross Vehicle Weight Rating (GVWRs) or the Gross Vehicle Weight (GVWs) of the power unit and the towed unit(s), or any total of these values that is highest
Trailer < 10,001 pounds but power unit 26,001+ pounds = Class B license
If the trailer is less than 10,001 pounds, but the power unit has a Gross Vehicle Weight (GVW) or Gross Vehicle Weight Rating (GVWR) of 26,001 pounds or more, you need a Class B license.
