What is the main function of traffic cones in a work zone?

The primary function of traffic cones in a work zone is to direct and alert traffic about changes. Traffic cones are designed to be highly visible and can be strategically placed to guide vehicles safely through or around construction areas. Their bright colors and reflective materials serve to draw attention, ensuring that drivers are aware of possible hazards or altered road conditions ahead. This helps to manage traffic flow and minimize the risk of accidents by highlighting restrictive areas and detours.

While marking boundaries and providing information about detours are important, these tasks are secondary to the main role of ensuring safe navigation for vehicular and pedestrian traffic. Decorative elements do not align with the practical purpose of traffic cones, as their design focuses solely on safety and traffic management in work zones.
