Which of the following activities may improve safety while driving a bus in fog?
Show the correct answer
Correct answer
B. Keeping a larger distance from the preceding vehicle.
Explanation
In the photo you can see a road in thick fog, in which trees and street lamps disappear after a few dozen metres. When driving a bus in fog, you will improve safety by keeping a greater following distance from the vehicle in front - answer B.
The Road Traffic Act requires you to exercise particular caution in conditions of reduced visibility and to keep the distance needed to avoid a collision. In fog you see an obstacle later, and a damp roadway makes the braking distance longer, so a greater following distance gives you time to react. Main beam headlights (answer A) reflect off the fog droplets and create a bright wall in front of you, so you see even less - in fog you switch on dipped headlights or front fog lights. Rear fog lights (answer C) may be switched on only when visibility is less than 50 m, and when visibility is better you must switch them off, because they dazzle the drivers behind you.
