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:
- Class A (Combination Vehicles) – Example would include tractor trailers.
- Class B (Heavy Straight Vehicles) – Example would include transit busses.
- 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.
Overview of CDL Endorsements
In addition to earning your CDL license, you can also earn endorsements. These endorsements allow you to operate certain vehicles.
The more endorsements you have, the more opportunities you will have. View the table below for the different endorsements available.
| Endorsement | Code |
| CDL Air Brake | A |
| CDL Combinations | X |
| CDL Doubles and Triples | T |
| CDL HazMat | H |
| CDL School Bus | S |

| CDL Passenger | P |
Please note that the CDL general knowledge test is not listed in the table above. It is technically not an endorsement. However, it is the first test you will have to complete to earn your CDL.
