Trailers and pole trailers must have brakes if the gross weight, including cargo, is 4,500 lbs. or more. However, if your trailer has a gross weight between 4,500 and 15,000 lbs., it does not need brakes if it is being towed at less than 30mph. In Texas, there are additional trailer rules you must follow. Each power unit must be equipped with a parking brake. A motor vehicle used to tow a trailer, semitrailer, or pole trailer equipped with brakes must also be equipped with service brakes. These brakes should be arranged so that, in case of a breakaway of the towed vehicle, the towing vehicle can stop by use of its service brakes.
