What is the primary function of cones in a work zone?

The primary function of cones in a work zone is to mark the edge of the work area and provide visual guidance. They are essential for directing traffic safely around construction or maintenance activities. Cones serve to alert drivers to changes in the roadway, helping them understand where they need to navigate to avoid potential hazards. Their bright colors and reflective materials enhance visibility, especially in low-light conditions, and they help to create a clear boundary around the work area. This delineation reduces confusion and helps maintain safety for both workers and drivers by directing traffic flow effectively and preventing vehicles from entering hazardous areas.
