What should drivers do when encountering a pedestrian at a crosswalk?

Answer: B — Stop and yield the right of way

Drivers must stop and yield the right of way to pedestrians at crosswalks because it ensures the safety of individuals who are crossing the street. Crosswalks are designated areas meant for pedestrians to traverse the road safely, and traffic laws in Illinois emphasize the importance of giving pedestrians priority in these zones. This practice reduces the risk of accidents and ensures a smoother flow of movement for both pedestrians and vehicles. By stopping and remaining alert for pedestrians, drivers contribute to a safer environment for everyone on the road.
