You are driving on a single-track road and see a vehicle coming towards you, while your engine temperature warning light comes on. What should you do to deal with both the road situation and your vehicle safely?

Explanation

On single-track roads, Rule 155 of the Highway Code says you should use passing places, pulling into one on your left to let oncoming vehicles pass. You must not stop in the middle of the road, as this creates a hazard. If a warning light comes on, you should deal with it as soon as it is safe. The safest option is to use the passing place correctly for the oncoming vehicle, then stop in a safe position off the running lane to investigate the vehicle fault, following basic vehicle maintenance and safety practice.
