What negative effects can snow or ice on the roadway have on the driver?
Show the correct answer
Correct answer
B. Reduced tyre grip on the road.
Explanation
In the photo there is a snow-covered road through a forest with snowy shoulders and a warning sign about a bend. Snow or ice on the roadway reduces tyre grip on the road - the answer is B.
The Road Traffic Act requires you to drive at a speed that allows you to keep control of the vehicle, taking into account the condition of the road, visibility and the weather conditions. Snow and ice create a layer between the tyre and the asphalt on which the tyre cannot "grip": the coefficient of grip becomes several times lower, so the braking distance becomes up to several times longer, and every sudden movement of the steering wheel, accelerator or brake ends in a skid. Answer A talks about increased grip, which is the exact opposite of reality; answer C about a shorter braking distance - also the opposite. On such a road you slow down before a bend on the straight, not in the bend, you keep a following distance behind the vehicle in front that is several times longer, you brake gently and early, and in the bend you keep a constant, low speed. Winter tyres help, but they do not cancel physics - speed remains the most important thing.
