Groups of commercial motor vehicles:
- A for Combination Vehicle
- B for Heavy Straight Vehicle
- C for Small Vehicle
Endorsements:
- T for double/triple
- P for passenger
- N for tank vehicle
- H for hazardous materials
- X for a combination of tank vehicle and hazardous materials

Any state-specific codes for additional grouping of endorsements issued at the discretion of the state must be fully explained on the front or back of the CDL document.
