In State v. Bishop, Del. Super., Gebelein, J. (May 4, 1990) (Mem.Op.), the police officer observed a car parked on the street and he noted that there was no license tag on the vehicle's bumper. He erroneously believed that the defendant's vehicle was not subject to being stopped for a motor vehicle violation because the vehicle was not in motion. Once the vehicle was in motion, the officer stopped the car. After he stopped the vehicle, he observed a registration tag taped to the rear window. Since the police officer observed no license plate displayed on the vehicle as required by Delaware law, the Delaware Superior Court held that there was a valid reason for the stop.
