Final answer:
When an ambulance with a flashing blue beacon is behind you, safely signal and pull over to allow it to pass. Do not stop abruptly or block its path. After it has passed, resume your journey, following traffic laws.
Step-by-step explanation:
When you're being followed by an ambulance showing a flashing blue beacon, you should take prompt and safe action to facilitate its passage. It is important to stay calm and not panic.
The correct procedure is to signal your intention, pull over to the side of the road, and stop if necessary, to allow the ambulance to pass. Under no circumstances should you stop abruptly or obstruct the ambulance's path, as this could create additional hazards. Once the ambulance has passed, you can continue on your way, ensuring that you follow all traffic laws. It is also advised to be aware of any additional emergency vehicles that may be following the first ambulance.
