Cones are commonly used as traffic control devices in work zones because they effectively guide drivers, delineate safe pathways, and indicate where vehicles should not go. Their bright color and reflective materials improve visibility, ensuring that drivers can see them in various conditions, whether during the day or at night. Cones are lightweight and can easily be moved or adjusted as the work zone evolves, allowing for flexibility in managing traffic flow.

While speed bumps are intended to slow down vehicle speed, they do not serve the primary purpose of guiding traffic through a work zone. Roadblocks completely obstruct roadway access, which may not be appropriate for managing traffic in a work zone where some level of passage is usually required. Traffic lights are typically used at intersections to control the flow of vehicles rather than in a temporary work zone setting. Thus, cones are the most suitable choice for guiding drivers through a work zone effectively.
