Show the correct answer
Correct answer
C. When the roadway or track is covered in snow.
Explanation
In the photo we are driving a tram on tracks in the roadway, with parked cars standing next to them. It is most difficult to judge the distance from a parked vehicle you are going around when the roadway and the track are covered with snow - the answer is C.
Under the snow you cannot see the rails, the edges of the roadway or the lines, which usually help you judge whether a parked car is sticking out into the clearance gauge of the tram (skrajnia). The tram driver has no reference points, and the snow also changes the way obstacles look. Rain (answer A) and fog (answer B) make visibility worse, but the rails and the edges stay visible. When the track is covered with snow, you drive past parked cars very slowly, and if in doubt, you stop the tram.
