CDL Classes

If you received your commercial learner's permit after February 7, 2022, you will need to complete an FMCSA approved ELDT training program to be eligible to take a CDL skills test.

There are three classes of commercial driver's licenses (CDL):

  • Class A - Any combination of vehicles with a gross combination weight rating (GCWR) of 26,001 pounds or more, provided the gross vehicle weight rating (GVWR) of the vehicle being towed is more than 10,000 pounds.
  • Class B - Any single unit vehicle with a GVWR of 26,001 pounds or more or any vehicle like that towing a vehicle that does not weigh more than 10,000 pounds.
  • Class C - Any single vehicle, or a combination of vehicles, that are not Class A or B vehicles, but can carry 16 or more people (including the driver), or have a hazmat placard.

If you have a Class A, B or C CDL, you may drive a three-wheel vehicle, but not a two-wheel motorcycle with a side car.

Your CDL will expire every eight years unless you have a hazardous material (Hazmat) endorsement. A CDL with a Hazmat endorsement expires five years from the pass date of your Security Threat Assessment.
