What must a driver do when seeing a pedestrian in a marked crosswalk?

When a driver sees a pedestrian in a marked crosswalk, yielding the right of way is essential for ensuring the safety of pedestrians. Marked crosswalks are specifically designed to indicate areas where pedestrians are encouraged to cross the road safely. By yielding, drivers demonstrate a commitment to following traffic laws, as well as prioritizing the safety of those on foot.

The legal expectation is that drivers must allow pedestrians to safely complete their crossing without undue interference. This practice helps prevent accidents and fosters a more pedestrian-friendly environment. Traffic regulations typically mandate that drivers give way when pedestrians are present in these designated areas, highlighting the importance of awareness and cautious driving behavior in urban settings.

The other options present actions that do not align with safe driving practices and legal requirements regarding pedestrian crossings. For instance, accelerating to pass a pedestrian, signaling with headlights, or continuing to drive without stopping disregards pedestrian rights and could lead to dangerous consequences. Therefore, yielding the right of way is the correct and responsible action for drivers when encountering pedestrians in marked crosswalks.
