When driving in fog, the braking distance:
Show the correct answer
Correct answer
A. may increase due to the wet road.
Explanation
The question is about the effect of driving in fog on the braking distance. It may become longer, because fog makes the roadway wet - answer A.
The Road Traffic Act requires you to exercise particular caution in conditions of reduced visibility caused by fog and to drive at a speed that takes into account the weather conditions and the state of the road. Fog is made of water droplets hanging in the air, which settle on the road surface: the roadway becomes damp and slippery, especially when the water mixes with dust or oil, and at temperatures close to zero it may become covered with frost. The grip of the tyres falls, so the braking distance becomes longer, not shorter (answer B), and it is not true that dampness has no effect on it (answer C). On top of that, in fog you see an obstacle later, so you slow down and increase your following distance.
Legal basis: Art. 30 para. 1 and Art. 19 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
