Which characteristic does a commercial motor vehicle typically possess?

A commercial motor vehicle is specifically defined as any motor vehicle that is used for business purposes, particularly in the context of transporting goods or passengers for compensation. The distinctive characteristic of commercial motor vehicles is their regular use for freight transport or for carrying more than a specified number of passengers, generally more than eight, including the driver.

This distinction makes option C the correct choice, as it accurately reflects the primary function of these vehicles within the realm of commercial transport. Vehicles used for freight transport are vital for businesses that engage in logistics and distribution, while those designed to carry more than eight passengers often serve in settings like shuttles, buses, and larger vans that are utilized for commercial passenger services.

In focusing on the other choices, vehicles designed solely for passenger transport do not encompass the broader functions associated with commercial motor vehicles, as they are not tailored for freight purposes. While many commercial vehicles may be modified for specific tasks, this characteristic is not exclusive to all commercial vehicles and does not define their primary use. Lastly, the ownership status of a commercial vehicle—whether leased or owned—does not impact its classification as a commercial motor vehicle; thus, that aspect does not define the vehicle's core commercial nature.
