Abstract: A roll warning system to alert a vehicle operator of the amount of transverse weight shift or roll of the vehicle. The warning system includes a pair of strain sensing units mounted to opposing suspension units of the vehicle, voltage generating circuitry responsive to the strain measuring units, and output circuitry responsive to the voltage generating circuitry for providing the warning indicia to the operator. Each strain sensing unit responds to the distortion induced by the weight of the vehicle in the suspension unit to which the sensing unit is attached by generating a signal representative of such distortion. The voltage generating circuitry receives these distortion representative signals, amplifies their difference, and generates a voltage representative of the difference in weight supported by each of the opposing suspension units.
