BDifficulty 2/5

When excessive speed narrows the useful visual field through tunnel vision, which hazard may be more easily overlooked?

Correct answer

A hazard appearing from the side, such as at a junction.

A hazard appearing from the side, such as a vehicle or pedestrian at a junction. Tunnel vision reduces the ability to pick up peripheral information and the time available to process it; it does not mean all side vision always disappears. It can also increase risk during overtaking, lane changes and motorway driving, rather than only at junctions. Moderate speed and scan the surroundings.
