High-visibility clothing, with its eye-catching colors and reflective strips, has become an important safety gear on the roads, significantly enhancing the visibility of wearers in complex environments.

Specific industries are required to wear high-visibility clothing.
In the construction industry, workers must wear Hi Vis workwear when working in outdoor construction areas, whether they are erecting scaffolding, transporting materials, or conducting foundation excavation, to prevent being accidentally injured by engineering vehicles or passing vehicles; for road maintenance and traffic control personnel, Hi Vis clothing is a standard requirement when working on highways or main urban roads or directing traffic, even during the day, they must wear it to ensure drivers can detect them from a distance; in the logistics and warehousing field, for forklift operators and goods sorters moving within the warehouse or in loading and unloading areas, due to frequent vehicle traffic and dense personnel, Hi Vis clothing can reduce collision accidents.

Wearing high-visibility clothing in low-visibility conditions becomes a necessity.
During night or dawn periods, as long as one is engaged in activities that require interaction with vehicles and machinery, such as night delivery personnel cycling, sanitation workers sweeping streets, or park rangers pruning roadside vegetation, they must wear Hi Vis clothing; in rainy, foggy, or hazy weather, with poor light penetration, even during the day, when working outdoors, cycling, or conducting public activities, Hi Vis clothing can enable others to detect the wearer's location more quickly, reducing the risk of accidents.

Special event participants are recommended to wear high-visibility clothing.
During large-scale events or gatherings, volunteers, security personnel, and medical staff need to serve in crowded areas, Hi Vis clothing can help participants quickly identify the staff and avoid collisions with the crowd; when children and the elderly go out, especially on school days, in parks, for walks, or when crossing the road, wearing Hi Vis jackets can make drivers more likely to notice such relatively slow-moving groups, reducing traffic accidents.

In summary, as long as there is a need for "quick identification of personnel to avoid risks", Hi Vis clothing should be the preferred choice. It is not only a guarantee of one's own safety but also a responsibility towards others.
