Explanation:
Why must you drive slowly now, and be ready to brake when a pedestrian suddenly crosses the road from behind a stopped bus?
Pedestrians might be crossing the road unexpectedly, particularly when a bus is present. They may step out from behind the bus without warning, making it important for drivers to reduce speed and be prepared to brake to avoid accidents.
