What is the correct course of action in this situation?

In situations where a sudden danger appears on the road—such as an unexpected obstacle, pedestrian, or a sudden stop of traffic—you must perform an emergency braking manoeuvre. German traffic regulations require drivers to react promptly and decisively to prevent an accident in such cases. This means, if an immediate hazard is present and normal braking would not be sufficient to stop in time, you must brake as hard as possible to minimize the risk of collision. Continuing to drive or merely being ready to brake is not sufficient when immediate danger appears; quick and forceful action is necessary to protect everyone on the road. This rule ensures that you are always prepared to respond to emergencies and help prevent accidents.
