A motor vehicle is a wheeled vehicle whose propulsion is provided by an engine or motor. The internal combustion engine is the most common motor choice, although electric motors or other types are sometimes used. Motor vehicles or road vehicles typically run on public roads. The rules of the road are laws or practices which all road users must obey; many relate specifically to motor vehicles or subtypes of them.
