When can you use high-beam lights while driving a truck from dusk till dawn?

Explanation
Correct answer: On unlit roads, as long as this does not blind other drivers.
In accordance with the regulations of the Road Traffic Act, main beams may be used from dusk to dawn only on unlit roads. However, they must be switched off when there is a risk of dazzling other drivers, which, in the heavy traffic situation shown, prevents them from being switched on.
