A priority vehicle travelling in emergency service will be given way...

Correct answer

by taking the measures appropriate to the circumstances at the time.

When you encounter a priority vehicle in emergency service, such as an ambulance, a fire engine or a police vehicle, you must give way by taking the measures appropriate to the circumstances of the moment and the place. This involves: Recognising the Emergency Signals: Watch out for special signals, such as flashing blue lights and sirens, which indicate that a vehicle is in emergency service. Pulling Over to the Right: The most common action is to pull over to the right of the road, whenever it is safe to do so, to allow the emergency vehicle to pass. Stopping if Necessary: In some situations, it may be necessary to bring your vehicle to a complete stop to give the priority vehicle enough space.
