If a taxicab operator desires to substitute one vehicle in place of another and if such vehicle to be substituted complies with the taxicab operator's license and the taxicab operator brings both the vehicle under the license and the vehicle to be substituted to a place designated by the law enforcement agency, the law enforcement agency may remove the license plate or decal from the licensed vehicle and place it on the vehicle to be substituted. If the law enforcement agency finds that it is impossible or impracticable to bring the licensed vehicle to the place designated, he may permit the licensee to detach the license plate or decal therefrom, by breaking the seal and removing the screws, and may waive the requirement that such vehicle be brought to such designated place. Under no other circumstances may this seal or decal be broken or removed by anyone but the law enforcement agency or other designated agency or officer of the city.
