When using cones in a work zone, what is their primary purpose?

The primary purpose of cones in a work zone is to guide vehicles through the area safely. Cones serve as visual indicators that delineate the path vehicles should follow, helping to direct traffic away from hazardous areas and around obstacles. Their bright colors and reflective surfaces enhance visibility, especially in low light conditions or during poor weather, making it easier for drivers to navigate through the work zone without confusion.

While cones may improve visibility in the sense that they stand out to motorists, their main function is to serve as a means of guidance. Instead of being decorative or serving as physical barriers, which would require a different type of equipment for effective separation of traffic from work areas, cones are specifically designed to convey direction and alert drivers to changes in the road or traffic conditions.
