What is required for a vehicle to be considered a motor vehicle?

A vehicle is considered a motor vehicle if it is self-propelled. This definition encompasses a wide range of vehicles that utilize an engine or motor to move independently without the need for external power sources, such as being towed. Self-propulsion is a fundamental characteristic of motor vehicles, distinguishing them from non-motorized types of transport.

Other options might suggest irrelevant specifications. For example, minimum seating capacity or speed limits do not serve as defining characteristics for all motor vehicles. Similarly, the requirement for a vehicle to be electric is not accurate, as motor vehicles can be powered by various fuel types, including gasoline or diesel, in addition to electric sources. Thus, the defining feature is its ability to propel itself, which is crucial for classification as a motor vehicle.
