What can you expect during sudden braking in these road conditions?
Show the correct answer
Correct answer
C. Decreased traction of the wheels to the road.
Explanation
In the photo you are driving along a city street in winter: the roadway is wet, with remains of snow and slush along the edges. During sudden braking in these conditions, you can expect decreased traction of the wheels to the road - answer C.
The Road Traffic Act requires you to drive at a speed that ensures control over the vehicle, taking into account the condition of the road and the weather conditions, and to brake in a way that does not cause danger. Water, melting snow and slush form a layer between the tyre and the surface that reduces friction - the tyre loses grip, the wheels lock more easily, and the braking distance can be as much as twice as long as on dry asphalt. Answers A and B are the opposite of the truth: neither traction nor friction increases on a wet and snowy roadway. In a lorry there is also the mass and the long braking distance, and when a combination with a semi-trailer brakes suddenly, the semi-trailer may swing out to the side. That is why in winter you increase your following distance, brake earlier and gently, and choose your speed for the worst part of the road.
