What is a "high-visibility safety vest"?

A high-visibility safety vest, also known as a reflective vest, is a type of protective clothing that is designed to increase the visibility of the wearer in low light or poor visibility conditions. These vests are usually made of fluorescent yellow or orange material and feature reflective strips or panels that reflect light from headlights or other sources. They are commonly worn by construction workers, road crews, emergency responders, and other workers who work in high-risk or low-visibility environments. The bright colors and reflective material help to make these workers more visible to motorists and other workers, reducing the risk of accidents and injuries.
