Which class of CDL applies to a driver who transports 16 or more passengers including the driver or carries hazardous material?

The correct classification for a driver who transports 16 or more passengers, including the driver, or carries hazardous materials is indeed the Class C CDL. This class is specifically designed for vehicles that are not covered by Class A or Class B, where the focus is on driving smaller vehicles that still have significant requirements due to the potential passenger count and the nature of hazardous materials.

A Class C CDL is intended for drivers who operate vehicles like buses or vehicles meant to carry hazardous materials, which necessitate additional training and adherence to safety regulations. This ensures that individuals operating these vehicles are adequately prepared to handle the responsibilities associated with transporting groups of people or potentially dangerous cargo.

In contrast, Class A CDL is meant for operating combination vehicles with a Gross Vehicle Weight Rating (GVWR) over 26,001 pounds, while Class B CDL is for operating single vehicles over 26,001 pounds or those carrying a specific number of passengers. Class D CDL is generally a non-commercial driver's license and does not pertain to commercial driving qualifications. Thus, the criteria for a Class C CDL align precisely with the requirements set out in the question.
