What is the minimum visibility distance for retroreflective vests?

The minimum visibility distance for retroreflective vests is established to ensure that individuals working in or near traffic can be seen by drivers from a significant distance. A visibility distance of 1000 feet is crucial because it allows enough time for drivers to notice the presence of workers, especially in low-light conditions or in adverse weather situations. This distance is based on safety standards designed to minimize accidents and enhance the safety of both the workers and road users.

The specific requirement for 1000 feet ensures that the retroreflective material in vests effectively reflects light from vehicle headlights, making the workers highly visible to approaching traffic. Adequate visibility is essential for providing both the workers and drivers ample reaction time to avoid dangerous situations.
