Which of the following best describes Class C vehicles?

The correct answer highlights that Class C vehicles encompass trucks and buses that have a Gross Vehicle Weight Rating (GVWR) of over 10,000 pounds. In the context of vehicle classification, Class C typically refers to commercial vehicles designed for transporting passengers or cargo, which aligns with the characteristics of trucks and buses that exceed this weight threshold.

By understanding that Class C includes vehicles that are heavier and often used for business purposes, it becomes clear why this classification exists. Vehicles in this category may also require specific licensing and inspection standards due to their size and potential for carrying a larger load.

The other classifications relate to different types of vehicles that do not fall under the Class C parameters. Motorhomes and three-wheeled vehicles are generally categorized differently, as are trailers that do not utilize air brakes and personal automobiles. The specifics of these other categories help to establish the distinct nature of Class C vehicles in the broader landscape of vehicle types.
