Road studs, also known as cat's eyes or reflective road markers, are small devices embedded in road surfaces to provide guidance and improve visibility for drivers, especially during low-light conditions or adverse weather. They serve as a safety measure by reflecting vehicle headlights and helping drivers maintain proper lane discipline and orientation on the road. Road studs are typically made of materials that can reflect light, such as glass or plastic, and they come in various shapes and colors. These markers are installed in a pattern along the centerline and edges of roads, highways, and other transportation routes to enhance nighttime visibility and prevent accidents. read more at: https://easternhighway.com/what-are-cateyes-and-how-are-they-important/
