<p>Novel improvement in the means whereby the operator of a motor vehcile can and/or will be forewarned (C-1) whenever the vehicle according to the rate of speed at which the vehicle is moving, is travelling too close behind another vehicle. The operator is able to apply brakes and stop, in time, in order to prevent a collision or accident. Such being accomplished by means of the provision of a motion detecting apparatus incorporated within the operator"s vehicle, and working in conjunction with a specially constructed speedometer (B), which gauges the rate of speed, computes the relative distance between the two said vehicles, automatically emits a sensing beam (C-9), wave or signal to detect any dangerously close vehicle in its path and gives-off a warning signal (C-1). </p> |
