ABSTRACT:
A system for alerting drivers of vehicles which have an overall height too great to clear an overhead obstruction in their path. Respective pairs of cooperating light sources and light sensors are spaced at appropriate distances from each other and in advance of the overhead structure, with the light beam from each light source being directed to the corresponding light sensor with which such light source is paired. The respective light beams are momentarily interrupted or broken as a vehicle having an excessive overall height passes the successive pairs of light sources and light sensors. When the light beams have been broken in sequence and within a preset, given time period, a signal is sent to the control station which in turn activates a visible, flashing, electric sign indicating that the approaching vehicle is too high to clear the obstruction and warning the driver of the vehicle to stop or exit from the thoroughfare. If the light beams are not broken in sequence within the preset time period, the system will automatically clear and reset itself to ready status. A message of the overheight vehicle can be transmitted to the proper highway authorities simultaneously with the activation of the warning sign. A mechanical sensor can be located on the overhead structure, with an associated camera to take a picture of the vehicle if the driver fails to stop and collision with the overhead structure occurs. A collision message can also be transmitted to proper highway authorities.
