The crossing guard aids in the safety of pedestrians of all ages. They are tasked for assisting youngsters in crossing streets safely and stopping traffic when necessary near schools. Crossing guards use signs, flags, and hand signals to steer vehicle traffic and pedestrians past barriers and employees on construction sites and other hazardous situations. They activate warning signal lights at railroad crossings, lower crossing gates until trains pass, and raise gates when crossings are clear. 

This is a position that necessitates a functional knowledge of traffic safety rules and procedures. As a result, many crossing guards are frequently overseen by the local police department. Although a high school graduation is recommended, it is not required. The majority of security guards are trained on the job. The labour is done outside, day and night, in good and poor weather. In fact, when the weather is bad, the work becomes even more crucial because it is more difficult for drivers and pedestrians to see clearly. 

Crossing guards must be able to respond swiftly in addition to having good vision. They must also have the stamina to stand for an extended period of time. It may appear that crossing guards have a simple job, yet their lives depend on them.
