Abstract
A method and system to detect and identify a target vehicle displaying a switched or invalid license plate includes a license plate reader to read the plate number carried by a target vehicle in its area. A pair of spaced laser beams measures the speed and length of the traveling vehicle. The read license plate numbers are compared with a data base of registered vehicles to obtain the length of the vehicle registered for that plate. If the registered length differs from the measured length, the plate may be illegally on the target vehicle.
