You are driving at night on an unlit road. There is a motor vehicle travelling a short distance in front of you. Which lights must you have on?

When driving at night on an unlit road, having the appropriate headlights is crucial for safety. Dipped headlights are necessary because they provide adequate illumination without blinding other drivers. In this situation, using only side lights would not be sufficient, as they do not provide enough visibility for nighttime driving on dark roads. Full beam headlights can be used if no other vehicles are present, but they can be hazardous to oncoming traffic. Therefore, the correct approach is to use dipped headlights, as required by German traffic regulations, ensuring safety for both the driver and others on the road.
