A method of detecting gross weight overload of a vehicle comprising the steps of positioning one or more ultrasonic sensors on the vehicle so that said sensors measure the distance to a ground surface, using the sensors to measure height above the ground surface of the vehicle in a non-overloaded condition, adding known weights to the vehicle until maximum gross vehicle weight (GVW) is attained, ascertaining height above the ground surface at this gross vehicle weight (GVW), and continuously measuring height of the ground surface and collecting height above the ground surface data to establish when an overload condition occurs.
