A traffic cone, typically made of bright orange PVC, is a conical marker used to indicate temporary hazards or redirect traffic. These cones are usually hollow and lightweight, making them easily portable. They often have reflective sleeves or strips to enhance visibility, especially in low-light conditions or at night. Traffic cones come in various sizes, with larger ones commonly used on highways and smaller ones for localized areas like construction sites or road repairs. Their vibrant color and recognizable shape make them a ubiquitous symbol of caution and safety on roads worldwide.
