Show the correct answer
Correct answer
A. Tiredness, reducing the efficiency of sight.
Explanation
In the photo a blue bus is driving along a city street next to other vehicles. Tiredness that reduces the efficiency of your eyesight has a negative effect on observing the road - answer A.
The Road Traffic Act requires every road user to be careful, and a driver can do this only when rested. Tiredness weakens eyesight: the eyes switch more slowly between near and far, the field of view narrows, and the reaction to what appears at the side is delayed. In addition, a tired driver starts to "stare" at one point and stops checking the mirrors. Passengers sitting in their seats (answer B) do not interfere with observing the road, and the comfort of a passenger seat (answer C) has no effect on it at all. That is why you keep to breaks and rest periods, and when you feel sleepy, you stop in a safe place.
