What are the four types of vehicle classifications for the CDL?

The correct answer identifies the four primary classifications for commercial driver's licenses (CDLs) as Class A, Class B, Class C, and Class D.

In this context, Class A allows the driver to operate combination vehicles with a gross combined weight rating (GCWR) of 26,001 pounds or more, provided the towed vehicle is more than 10,000 pounds. Class B pertains to single vehicles with a gross vehicle weight rating (GVWR) of 26,001 pounds or more, or any such vehicle towing a vehicle not more than 10,000 pounds. Class C is designated for vehicles designed to transport 16 or more passengers (including the driver) or hazardous materials.

The inclusion of Class D is somewhat unusual in the context of commercial licenses since it generally relates to standard passenger vehicles rather than commercial vehicles. However, in some states, Class D may be referenced in discussions about licensing structure, particularly for those who do not fit into the other classifications.

The other options presented use different classification systems that do not align with the standard terminology for CDLs in the U.S., which is why they are not applicable in this case.
