To delineate a work area and direct traffic away from hazards

The role of cones in traffic control is primarily to delineate a work area and direct traffic away from hazards. Cones are highly visible, portable devices that are used to create a temporary boundary around areas where work is taking place. This helps in managing the flow of traffic by alerting drivers to potential hazards, such as road construction or maintenance activities, ensuring the safety of both the workers and the traveling public.

By effectively guiding drivers and outlining where vehicles can and cannot go, cones play a critical part in maintaining organization in traffic patterns and preventing accidents. Their bright color and reflective materials make them easily noticeable, which is essential for alerting drivers of changes in roadway conditions. This function is crucial in temporary situations where permanent barriers are not feasible, making cones an essential tool in traffic control management.
