You are driving with main beam lights on in darkness. When do you have to dip your headlights?

Your answer was correct because you identified both situations where dipping your headlights is necessary.

1. Driving on a road with constant, adequate lighting requires you to dip your headlights to avoid blinding other drivers, as the bright light is unnecessary in well-lit areas.

2. When waiting at a rail crossing, it's crucial to dim your lights to prevent dazzling the train operator or other road users.

Not selecting the third option regarding pedestrians is acceptable in this context, but it's important to note that it's good practice to use dipped lights when pedestrians are present, particularly to avoid any potential glare and ensure their safety. Recognizing all appropriate situations ensures compliance with German traffic regulations and enhances safety for everyone on the road.
