Crossing guards are individuals, often found near schools, who help children and pedestrians safely cross streets. They typically wear bright uniforms or vests to be easily visible to drivers. Their main responsibility is to direct traffic and ensure that it stops when people need to cross. These guards often work during school hours, especially before and after classes, when foot traffic is highest. They may use stop signs or flags to signal vehicles to halt. By providing this service, crossing guards play a crucial role in promoting safety for students and the community, reducing the risk of accidents near busy roads.
