Pedestrian signals are traffic control devices that help people safely cross streets. They typically consist of lights that indicate when it is safe to walk or when to wait. A green figure usually means "walk," while a red hand signals "don't walk." These signals are often found at intersections and are designed to improve safety for pedestrians. They work in conjunction with traffic lights for vehicles, ensuring that both drivers and walkers can navigate the roadways safely. Proper use of pedestrian signals helps reduce accidents and promotes orderly traffic flow.
