What is the right thing to do in this situation?

According to German traffic law, when you approach a bus that is stopped at a bus stop and is displaying its hazard warning lights, you must only pass it at walking speed—even if you are driving in a city. This rule protects passengers who may be crossing the street or getting on and off the bus. The restriction applies in both directions on roads without a central divider, and for vehicles traveling in the same direction as the bus even with a divider.

In this scenario, you correctly chose that you are only allowed to pass the bus at walking speed. Continuing at normal speed or assuming that the other car must stop is incorrect. Always reduce your speed to walking pace and be ready to stop if needed when overtaking a stopped bus with hazard lights. This ensures the safety of bus passengers, especially children. Remembering this rule will help you pass similar questions and act safely in real situations.
