Types of CDL License & Endorsements
Thinking about getting your CDL? Driving certain commercial motor vehicles (CMVs) requires special skills and knowledge. Acquiring a CDL license or special endorsement through study and training proves the driver does possess the skills and knowledge required for them to be successful at their truck driving job.
What is a CDL?
On October 27, 1986, the Commercial Motor Vehicle Safety Act was signed into law, which made getting your CDL a more stringent process. The goal of the new law was to improve highway safety by ensuring that drivers of large trucks and buses were qualified to operate those vehicles. The act also made sure that unsafe and unqualified drivers were removed from the highways. The CMV Safety Act retained the state’s right to issue a driver’s license but established minimum national standards states must meet when issuing CDLs.
Types of CDL – Commercial Driver’s License
There are three CDL types to earn and they’re based on the total weight and design of the CMV driven.
Class A License – Any driver operating a vehicle and trailer with a combined weight of more than 26,001 pounds is required to have a Class A CDL, provided that the trailer’s Gross Vehicle Weight Rating (GVWR) exceeds 10,000 pounds. Try the Class A CDL license practice test
Class B License – A Class B CDL is required for vehicles weighing in excess of 26,001 pounds or vehicles that are pulling another vehicle with a GVWR of less than 10,000 pounds. Read more about Class B>>
Class C License – Large passenger vehicles and vehicles used to haul hazardous materials are covered by a Class C CDL. Class C licenses are required for vehicles that carry more than 16 passengers (including the driver). Any vehicle carrying hazardous materials require a placard. Selective agents also require a Class C CDL to operate.
