The Road Traffic Act allows you to use the rear fog lights when visibility is reduced to less than 50 m, and requires you to switch them off immediately when visibility improves, because in normal conditions they dazzle drivers behind you. Their strong red light is visible from far away and warns drivers behind you that your vehicle is ahead of them. In addition, you switch on the dipped headlights or the front fog lights, slow down and increase the following distance.
