ABSTRACT:
A warning system designed to be interconnected between a towing vehicle such as a conventional automobile and a trailer or like device comprising a towed vehicle wherein the warning system includes a circuit defined by electrically connected elements. Such elements include an indicator member which could be an audible alarm connected to a power source which in turn is electrically interconnected to one or more sensing arms mounted on the towed vehicle. The circuit is further defined by being electrically grounded to a conductive portion of the frame of the towing vehicle such that engagement between one of the sensing arms and a conductive portion of the frame of the towing vehicle causes a completion of the circuit and activation of the alarm member. The one or more conductive arms are mounted on the towed vehicle and configured and/or disposed to extend outwardly therefrom so as to engage a conductive portion of the frame of the towing vehicle when a predetermined angular orientation occurs between the towed and towing vehicle such as when the vehicles tend to "jackknife" relative to one another.
