You are driving at the speed limit on a main road when you see blue flashing lights from an emergency vehicle approaching behind you in heavy rain. What should you do?

Explanation

The Highway Code Rule 125 states that the speed limit is the absolute maximum, not a target speed, and it may not be safe to drive at that speed in all conditions. In heavy rain, you should reduce your speed to match the road and traffic conditions. When an emergency vehicle with flashing lights approaches, you must also allow it to pass safely. Slowing down and creating a safe opportunity for it to overtake, without braking harshly or stopping abruptly, follows both Rule 125 and the guidance on emergency vehicles.
