Traffic policemen usually wear reflective clothes. The car light will reflect light when it shines on it, and it has high recognition at night, which is conducive to the safety of traffic police on duty. The clothing has a strong visual impact effect, which can not only protect the personal safety of the police on duty, but also remind drivers to prevent collisions. Reflective clothing is mainly used for police, road law enforcement personnel, traffic police, road maintenance personnel, motorcycle and bicycle drivers, and staff in dim light.
