A commercial driver's license is required in the United States of America for drivers who want to operate commercial vehicles across state lines. Commercial vehicles frequently contain large, heavy, and prominently marked hazardous materials.
Any applicant wishing to operate any combination of vehicles with a gross vehicle weight rating (GVWR) more than 26,000 pounds (11,793 kg) pounds must possess a commercial driver's license.
Applying for the required endorsements on a commercial driver's license is required in order to drive vehicles such as buses or tank trucks or other specialty vehicles like hazardous chemicals.
Among the endorsements are passenger (P), which permits the transportation of passenger cars, and tank (T), which permits the use of commercial trucks for the transportation of heavy or liquid goods.
The last category is hazardous materials, which enable the candidate to handle dangerous items including explosives, radioactive materials, or flammable liquids. The FMCSR Commercial Motor Vehicle Safety Act requires the individual to get the necessary endorsements and submit to a background check in order to be granted a (S) school bus endorsement. The driver trainee must finish training from organizations that have been certified by the FMCSA in order to receive a commercial driver's license or endorsement.
Here are the types of CDL Licenses explained in following Table:
| Type of License Classes | Report | Vehicles that you can operate |
|---|---|---|
| Class A CDL | If the towed vehicle weighs more than 10,000 pounds, it is necessary for a combination of vehicles with a gross combined weight rating (GVWR) of 26,001 pounds or more to operate. | Flatbeds; tanker vehicles; semi-trailers; big rigs; eighteen-wheelers; and truck and trailer combos. |
