While driving a bus, when do you have to turn off the rear anti-fog lights?
Show the correct answer
Correct answer
C. When visibility increases to 60 m.
Explanation
In the photo you can see the rear of a coach on a sunny day - near the lower edge of the bumper two round red lamps are lit, most likely the rear fog lights. You must switch off the rear fog lights when visibility increases to more than 50 m - answer C.
The Road Traffic Act allows rear fog lights to be used only when reduced visibility limits the view to a distance of less than 50 m, and when visibility improves, it requires them to be switched off immediately. At 30 m (answer A) and 40 m (answer B) visibility is still below 50 m, so the lights may still be on. These lights are very bright, and in normal conditions they dazzle the driver behind you, and they can also hide your brake lights. With visibility like in the photo, these lights must be switched off.
