A crossing guard is a person, often a volunteer or city employee, who helps children and pedestrians safely cross the street, especially near schools. They typically wear bright uniforms or vests to be easily seen by drivers. Their main job is to stop traffic when necessary and guide people across the road. Crossing guards usually work during school hours, particularly before and after classes. They play a crucial role in ensuring the safety of students and other pedestrians, helping to prevent accidents. Their presence encourages safe behavior among both drivers and walkers in busy areas.
