Claim 1:
2. A system for the detection and subsequent alarm for an upward movement of vehicles on a vehicle transport carrier such that a vehicle would be at such a height as to impact the underside of a highway overpass where said system comprises two or more vertical posts mounted to the sides of the vehicle transport carrier with a laser measurement sensor mounted at the top to one of said vertical posts where said laser measurement sensor measures the distance from its position to the ground and provides the measured distance to the ground on a continuous basis to said vehicle transport carrier's driver and said vehicle transport carrier's home terminal, and infrared light emitting diodes are mounted on one or more of said vertical posts with corresponding photo detectors mounted on said vertical post opposite the infrared light emitting diodes where said infrared light emitting diodes and corresponding photodetectors are positioned to detect an upward movement of vehicles on said vehicle transport carrier provide an alarm to the vehicle transport carrier driver and said vehicle transport carrier's home terminal if the infrared light beam between said infrared light emitting diode and corresponding photodetector is interrupted.
