Show the correct answer
Correct answer
A. Tiredness, which strains vision.
Explanation
In the photo, the road enters the town of Majdan Nowy - a green board with its name stands at the right edge. The way a tractor driver observes the road may be affected by tiredness, which reduces the efficiency of vision - answer A.
A tired driver moves their eyes less often, stares "at one point", judges distances worse and notices hazards later, and the eyes get tired faster, especially after many hours of work in the field. On top of that there is microsleep - a few seconds during which the tractor is moving without control. The type of road surface (answer B) affects grip and braking, and the width of the lane (answer C) affects how much space you have, but neither of these features changes how your eyes take in the picture of the road. Only a person who is physically and mentally fit may drive a vehicle. During harvest or sowing take breaks, drink water and do not set off when your eyes are closing by themselves.
