What do you have to be aware of in this situation?

Your answer is correct because German traffic rules require drivers to be especially cautious when passing a stopped bus at a bus stop. First, pedestrians—especially children or elderly people—may suddenly cross the road from in front of the bus, so you must be prepared to stop quickly. This aligns with the first point that pedestrians could cross the road.

Second, the law states that if the bus is stopped and using its hazard lights (or if there is a visible reason to expect pedestrians), you must drive past at walking speed (Schrittgeschwindigkeit, about 7 km/h). This reduces risk and reaction time if a pedestrian steps onto the road. While driving directly past a stationary bus is allowed, it must be done carefully and slowly, which is why the second point is also correct.

The third option is incorrect because you are allowed to pass a stopped bus if it is safe to do so, but at the appropriate reduced speed and with increased attention. These rules help prevent accidents involving pedestrians getting off or crossing near buses. Always remember to lower your speed and be alert in such situations to ensure everyone’s safety.
