What types of vehicles are classified as “commercial vehicles”?

The classification of commercial vehicles encompasses a wide range of vehicles that are specifically designed for commercial use, which may include but is not limited to those that exceed specific weight limits. This definition is broader because it recognizes that vehicles intended for business purposes can vary in size, weight, and function. For example, a van used for deliveries or a bus used for transporting passengers for hire would both fall under the category of commercial vehicles even if they do not exceed a weight of 10,000 pounds.

Understanding this classification is important because it helps in determining which vehicles require a commercial driver's license and adherence to certain regulations pertaining to safety, maintenance, and operation in the public interest. Recognizing that not only trucks but many types of vehicles can be commercial in nature reinforces the need for proper licensing and compliance with state and federal laws governing transportation.

The other options are too narrow or entirely incorrect as they either limit the definition of commercial vehicles or misidentify their intended use.
