You are driving within a built-up area during darkness. Oncoming drivers are flashing their headlights as a warning to you. What might this mean in this situation?

Flashing headlights from oncoming drivers typically serves as a warning sign. In this context, it can indicate two key issues:

1. Your vehicle may be dazzling other drivers with excessive or misaligned lights, which can cause temporary blindness and jeopardize safety on the road.
2. You may have forgotten to turn on your dipped headlights, leaving your vehicle inadequately illuminated at night, making it less visible to others.

Both points are critical for ensuring safety in built-up areas during darkness. It's essential to always use dipped headlights in such conditions to avoid dazzling others and to improve your visibility. Understanding these signs helps you respond appropriately and maintain safe driving practices according to German traffic regulations.
