Hello, I'm glad to answer your question. Generally speaking, people who wear reflective vests mainly focus on outdoor duty and work. They are mainly: traffic patrol, police, special police, sanitation, outdoor exploration workers and so on. In fact, in foreign countries, not only these people need to wear reflective vests, but also some fun run and night travelers can wear reflective vests, because the night light is weak and people's sight is blocked. If travelers can wear clothes with reflective stripes (reflective vests, reflective clothing, etc. ), they can give others a warning to ensure their own safety. Because there are certain restrictions on reflective vests in China, the requirements of reflective vests we see are relatively high only among special people, especially for police reflective vests. Domestic manufacturers and sales companies have relatively high requirements, and they must have at least provincial qualifications to produce or sell them. Gotai police equipment specializes in producing and selling reflective vests, which have passed the inspection by the Quality Inspection Center of the Ministry of Public Security. The police equipment procurement center of the Ministry of Public Security has designated enterprises, which are suitable for unit procurement. It is the most official way to buy reflective vests at present. It is precisely because of the special status of traffic patrol officers, special police officers and other personnel that they must use reflective vests when on duty and at work.
