Commercial driver's license

Commercial driver's license (CDL) is a legal authorization that permits the holder to operate certain types of motor vehicles. These vehicles are typically used for transporting goods or passengers over specified distances. In many jurisdictions, a CDL is required to drive vehicles above a certain weight, for transporting hazardous materials, or for carrying a certain number of passengers.

Requirements

To obtain a CDL, an individual must meet certain requirements. These typically include being at least 18 years old (21 if driving across state lines or for the transport of hazardous materials), possessing a valid driver's license, passing a medical examination, and successfully completing a training course. The individual must also pass a series of written and practical tests that assess their knowledge and skills related to the operation of commercial vehicles.

Classes

There are several classes of CDLs, each corresponding to a different type of vehicle. These include:

• Class A: This class covers 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(s) being towed is in excess of 10,000 pounds.
• Class B: This class covers any single vehicle with a GVWR of 26,001 pounds or more, or any such vehicle towing a vehicle not in excess of 10,000 pounds GVWR.
• Class C: This class covers any single vehicle, or combination of vehicles, that does not meet the definition of Class A or Class B, but is either designed to transport 16 or more passengers, including the driver, or is transporting material that has been designated as hazardous.

Endorsements

In addition to the basic CDL, drivers may obtain endorsements that allow them to operate special types of vehicles. These endorsements are typically indicated by a letter code on the license. Common endorsements include:

• H - Hazardous materials (HazMat)
• N - Tank vehicles
• P - Passenger vehicles
• S - School buses
• T - Double/Triple trailers
