What is the correct course of action in this situation?

You answered correctly. When you see a bus at a bus stop, especially when people are boarding or leaving the bus, you must drive with increased alertness and be prepared to react quickly to any passengers crossing the road unexpectedly. However, you do **not** always have to slow down to walking speed unless passengers are crossing or the bus signals that it will pull away. In this scene, maintaining your speed and being especially alert are the right actions, because the bus is at the stop and there is no immediate sign that people are crossing the road in front of you. Always be ready to slow down further if the situation changes.
