What is the correct course of action in this situation?

In this scenario, the proper course of action is to stop and allow the pedestrian, who appears to be preparing to cross the street, to do so safely. According to German traffic regulations, drivers must yield to pedestrians at crosswalks and areas where pedestrians are likely to cross, even if there is no designated crossing.

By stopping, you ensure the safety of the pedestrian, which is paramount in German traffic laws. This action demonstrates a responsible and cautious approach to driving, reflecting the importance placed on pedestrian rights and safety within the traffic system.

Additionally, it's worth noting that driving past the pedestrian without stopping could endanger them, and flashing headlights to signal is not an acceptable or safe alternative in this circumstance. It's essential to prioritize stopping to allow pedestrians to cross whenever they are present.
