A crosswalk is a designated area on the road where pedestrians can safely cross. It is usually marked with white stripes and may have signs to alert drivers. Crosswalks are often found at intersections or near schools, helping to ensure that people can walk from one side of the street to the other without danger. In many cities, traffic lights and signals are used in conjunction with crosswalks to manage the flow of both vehicles and pedestrians. When the light turns green for pedestrians, it indicates that it is safe to cross. This system helps protect walkers, especially children and the elderly, from accidents.
