Show the correct answer
Correct answer
C. When visibility increases to 60 m.
Explanation
The symbol in the photo is the warning light for the rear fog lights. These lights are very bright and are used only so that the driver behind you can see you in thick fog. You may use them when visibility is reduced to less than 50 m. When visibility improves to more than 50 m, you must switch them off immediately - the correct answer is C.
The Road Traffic Act says that a driver may use rear fog lights if visibility is reduced to a distance of less than 50 m, and when visibility improves, the driver must switch them off immediately. Switched on when they are not needed, they dazzle the drivers behind you and hide the brake lights.
