What should you do if there is a police vehicle behind you with alternating flashing blue and red lights?

If there is a police or customs vehicle behind you with alternating flashing blue and red lights you must pull over to the side of the road and stop. Wait in your car for instructions.

However, if there is a police car or other emergency vehicle approaching you from behind, with their sirens or blue lights on, you must make way, move over to the side and, if necessary, stop so that it can pass as easily as possible.
