What must you do in this situation when you are dazzled?

In this situation, when you are dazzled by oncoming headlights, it is essential to take specific actions to ensure your safety and that of others on the road.

1. **Look to the Right-Hand Edge of the Roadway**: This helps you maintain a reference point, allowing you to stay in your lane without being distracted by the blinding lights. You can better gauge the road's position and avoid veering off track.

2. **If Necessary, Reduce Your Speed**: Slowing down is crucial because dazzled vision can impair your ability to react. By reducing your speed, you can give yourself more time to recover from the glare and respond to any potential hazards.

Avoiding the third option of accelerating is important because trying to speed away may increase the risk of losing control or misjudging the distance and position of other vehicles.

Following these steps aligns with German traffic regulations aimed at maintaining safety while driving in challenging visibility conditions.
