By law all caravans must have a breakaway cable to apply the brakes if the caravan becomes uncoupled from its tow vehicle while on the move. After the brakes have been applied, the cable is then designed to break, allowing the caravan to come to a halt away from the tow vehicle. The cable must follow as straight a line as possible to be correctly connected to the tow vehicle. It should pass through a purpose-designed anchor point on the towbar and then be looped back and clipped to itself. If there is no suitable anchor point on the towbar, there is nothing in law to prevent it being looped once round the towball before being clipped back on itself.
