What is a Commercial Driving License?

CDL stands for commercial driver’s license. If you wish to operate a commercial motor vehicle (CMV), you will need to have your CDL.

There are 3 classes of CDL:

  1. Class A (Combination Vehicles) – Example would include tractor trailers.
  2. Class B (Heavy Straight Vehicles) – Example would include transit busses.
  3. Class C (Small Vehicles) – Example would include any vehicle used to transport 16 or more passengers or to transport hazardous materials.

The diagram below can be used to help you determine which class of CDL license you will need.
