What is the primary difference between Class A and Class B CDLs?

The primary difference between Class A and Class B Commercial Driver's Licenses (CDLs) relates to the types of vehicles a driver is authorized to operate. A Class A CDL permits the operation of combination vehicles, which are vehicles that have a gross combination weight rating (GCWR) of 26,001 pounds or more and also may tow a trailer over 10,000 pounds. This means that a Class A driver is trained and licensed to handle larger and more complex vehicles that are typically used in commercial transportation.

On the other hand, a Class B CDL allows the driver to operate a single vehicle with a gross vehicle weight rating (GVWR) of 26,001 pounds or more. This category does not typically include the towing of heavier trailers beyond that specified limit.

Understanding this distinction is crucial for drivers, as it indicates the level of training and proficiency required to safely operate different types of commercial vehicles. It ensures that drivers possess the necessary skills and knowledge to manage the specific challenges associated with combination vehicles versus single vehicles.
