You are approaching a bus stop marked like this. What do you do if you see children there?

Your answer is correct. When approaching a bus stop, especially if children are present, you must always reduce your speed and be ready to brake. This is required by German traffic law because children can behave unpredictably and may suddenly cross the street. The rule applies not just for school buses or during specific hours, but any time children are at or near the stop. Always approach with caution and prepare to stop if needed.
