What factor may impede proper observation of the road while driving a tram at night?
Show the correct answer
Correct answer
A. Inability to distinguish shapes in the dark.
Explanation
In the photo we see tram tracks at dusk in front of a junction with traffic lights. Correct observation of the road when driving a tram at night may be disturbed by being unable to recognise shapes in the dark - the answer is A.
In the dark the eye is worse at recognising shapes and contrasts, and a pedestrian in dark clothes may only be visible from close up. A driver who sees poorly after dark notices a danger later. Properly chosen glasses for night driving (answer B) and good sharpness of vision (answer C) help with observation - they do not disturb it. If you notice that you see worse at night, you go to an eye doctor.
