Reflective vests are used in a variety of environments, including:

Roadwork and Traffic Management： Workers on roads and highways wear reflective vests to ensure drivers can see them from a distance, even in low-light or night-time conditions.

Construction Sites： On construction sites, reflective vests are a safety requirement to help identify workers and prevent accidents.

Cycling and Running：Cyclists and runners often wear reflective vests to increase their visibility on roads, especially in the early morning or evening when it's dark.

Emergency Services：First responders, such as firefighters, paramedics, and police officers, often wear reflective vests during emergency operations, especially when working in traffic or dark environments.

Warehouse and Logistics：Workers in warehouses, factories, and distribution centers may wear reflective vests to enhance visibility, reducing the risk of accidents with vehicles or machinery.
