What should you do when you’re being followed by an ambulance showing a flashing blue beacon?

Explanation: When an emergency vehicle is behind with its blue lights flashing, you must remain calm and look ahead for a safe place to move over to let it pass. If you're waiting at red traffic lights, don't attempt to clear the way by driving past the red light; this is both dangerous and a traffic offence.
