RR-013 — Headlight Visibility Rule

Question

Apart from between sunset and sunrise, when else must your headlights be switched on?

A. When persons or vehicles are not clearly visible at 150 metres B. Only when another vehicle flashes you C. Only inside tunnels

Correct answer: A

Explanation

Headlights must also be on whenever visibility drops so that persons or vehicles are not clearly visible at 150 metres — for example in fog or heavy rain. Waiting to be flashed or limiting it to tunnels is incorrect.
