A breakaway device ( 10 ) to detect when a towed vehicle ( 14 ) separates from a towing vehicle ( 16 ) in order to engage the towed vehicle's brakes broadly comprises a sensor operable to detect when a signal from the towing vehicle ( 16 ) is lost and a shunt operable to route electrical power to the brakes. In a preferred embodiment, the sensor and the shut may be embodied in a transistor ( 26 ). In an alternative embodiment, the sensor and the shut may be embodied in an electro-mechanical switch ( 34 ). The device ( 10 ) preferably includes an override ( 42 ) and lights ( 44,46 ) to indicate the device's ( 10 ) status.
