You’re driving in heavy traffic on a wet road. Which lights should you use if there’s a lot of surface spray?

You must make sure that other road users can see you, but you don’t want to dazzle them. Use your dipped headlights during the day if visibility is poor. If visibility falls below 100 metres (328 feet), you may use your rear fog lights, but don’t forget to turn them off when the visibility improves.
