What factors may affect a proper observation of the road while driving a bus at night?
Show the correct answer
Correct answer
A. Inability to distinguish shapes in the dark and sensitivity to being blinded.
Explanation
In the photo you can see an unlit road at night, on which a vehicle with bright headlights is approaching from the opposite direction. Proper observation of the road at night may be disturbed by an inability to distinguish shapes in the dark and sensitivity to glare - answer A.
The Road Traffic Act requires you to drive at a speed that ensures control over the vehicle, taking into account the visibility of the road. At night the eye distinguishes shapes and colours less well, and after being dazzled by oncoming headlights it needs a few seconds to see in the dark again - during this time the bus travels several dozen metres almost blind. In some drivers these problems are particularly strong and require an eye test. Properly chosen glasses for night driving (answer B) and good visual acuity (answer C) help you observe the road rather than disturb it. When passing a vehicle that dazzles you, you look at the right edge of the roadway and slow down.
