What factor may impede proper observation of the road while driving a tram at night?

Explanation
Correct answer: Inability to distinguish shapes in the dark.
Driving a vehicle in night-time conditions, as shown in the picture, involves limited visibility. In darkness, the human eye's ability to perceive details, contours, and judge distances is significantly impaired, which hinders proper observation of the road. This situation can lead to a delayed reaction to unlit obstacles or pedestrians, posing a direct threat to safety.
