BDifficulty 2/5

What effect does the tunnel effect caused by speed have on the driver?

Correct answer

Reduces perception of lateral hazards as the useful visual field concentrates centrally.

It narrows the useful visual field and makes lateral hazards harder to perceive as attention concentrates centrally. This is a risk of excessive speed and reduces anticipation. It does not mean staring centrally guarantees perfect central vision or physically distorts objects at the sides. Reduce speed and actively observe the surroundings.
