How should a bus driver react to a pedestrian at a crosswalk?

Answer: B — Stop and allow the pedestrian to cross

A bus driver should stop and allow the pedestrian to cross at a crosswalk because it is a legal requirement and an important safety measure. Pedestrian safety is paramount, especially in areas where they have the right of way, such as crosswalks. By stopping and allowing pedestrians to proceed, the bus driver helps ensure that those crossing the street can do so safely without the risk of an accident. In this context, honking at a pedestrian does not provide a safe environment and could actually startle them, increasing the risk of an incident. Attempting to speed past a pedestrian or making a wide turn around them could create an unsafe situation, as pedestrians may be unaware of the bus's intention and could inadvertently step into its path. Stopping is the most responsible action a bus driver can take to protect the well-being of pedestrians at designated crossings.
