Are you permitted to use the rear fog lights, if fog restricts visibility to a distance of 100 m?
Show the correct answer
Correct answer
NO
Explanation
In the photo you are driving along a road with barriers in thick fog, which hides the section of the roadway further ahead. When fog limits visibility to 100 m, you are not allowed to use rear fog lights - you may switch them on only when visibility falls below 50 m. The answer is: no.
The Road Traffic Act states that the driver of a vehicle may use rear fog lights if visibility is reduced to less than 50 m, and when visibility improves, the driver must switch these lights off immediately. A rear fog light is very bright - as strong as a brake light - and with visibility of 100 m it dazzles the drivers behind you and blends in with the brake lights, so the driver behind cannot see when you are braking. In fog with visibility of 100 m you switch on dipped headlights or front fog lights, slow down and increase your following distance, and you save the rear fog lights for really thick fog, a snowstorm or a downpour, when you cannot see further than 50 m.
