Show the correct answer
Correct answer
B. On unlit roads, as long as this does not blind other drivers.
Explanation
In the photo, at dusk, a bus is stuck in a traffic jam on a multi-lane road, with heavy traffic in front and behind. From dusk to dawn you may switch on main beam headlights (high beam) on unlit roads if you do not dazzle others - answer B.
The Road Traffic Act allows you, from dusk to dawn, to use main beam headlights instead of dipped headlights or together with them only on unlit roads and only when you will not dazzle other drivers or pedestrians walking in a column. So the condition "unlit road" is just as important as not dazzling anyone - you must not use them on a lit street, which is why answer A is too broad. In thick fog (answer C) main beam headlights reflect off water droplets and make visibility worse - then you use dipped headlights and fog lights. In a traffic jam, as in the photo, main beam would dazzle the drivers ahead of you.
