What should you do when you see a pedestrian in a crosswalk?

Answer: A — Yield the right of way to the pedestrian.

When you see a pedestrian in a crosswalk, it is crucial to yield the right of way to them. This action demonstrates respect for pedestrian safety and obeys traffic laws designed to protect those on foot. Crosswalks are designated areas where pedestrians are allowed to cross the street, and yielding ensures they can safely complete their crossing without the risk of being struck by a vehicle. In terms of traffic laws, failure to yield to pedestrians in crosswalks can result in penalties, including fines and points on your driving record. Moreover, it promotes pedestrian rights and encourages a safer environment for everyone, contributing to lower accident rates and fostering mutual respect between drivers and those who walk. The other choices highlight behaviors that contradict safe driving practices. Speeding up can endanger the pedestrian and potentially lead to accidents; using your horn could startle pedestrians and is generally discouraged unless in a situation where you need to alert someone to an immediate danger; and continuing to drive without yielding is not only unsafe but also illegal in contexts where pedestrians have the right of way.
