Commercial driver's license

From WikiMD's Wellness Encyclopedia

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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
