Every motor vehicle manufactured after July 1, 1964 and used to tow a trailer or semitrailer must be equipped with a means for providing that the towing vehicle is capable of being stopped by the use of its service brakes.

Every motor vehicle, trailer, or semitrailer must be equipped with brakes that have a braking system arranged so that 1 control device can be used to operate all service brakes.
