Why are you required to brake here?

In this situation, you are required to brake because of the presence of a child. German traffic rules emphasize extra caution when children are near the roadway, as they may suddenly run onto the street or act unpredictably. Even if other elements, like cyclists or distant vehicles, are present, the main reason to reduce speed and be especially ready to stop is the increased risk posed by children. Recognizing this risk and reacting early by braking helps ensure safety for everyone. For similar questions, always consider children as an immediate reason to brake or slow down, regardless of other road users.
