shing lights, then you hear the siren. It’s an ambulance coming up quickly with lights and siren on.
Remember:
Stay alert while driving. Avoid distractions.
Signal, move to the side of the road, come to a safe stop – this is required in BC. Don’t block or drive on the shoulder of the road. All traffic moving in both directions must stop (except on a divided highway when the emergency vehicle is on the opposite side).
It’s illegal to follow any emergency vehicle responding to a call. Stay at least 150 metres behind.
