Advance warning signs are vital in work zones because they prepare drivers for upcoming changes in traffic patterns. These signs provide crucial information about the nature of the work zone, such as lane closures, detours, or speed reductions, allowing drivers to adjust their speed and driving behavior before they encounter the altered roadway conditions. This proactive communication is essential for maintaining safety for both drivers and construction workers.

Additionally, advance warning signs help reduce the likelihood of sudden stops or evasive maneuvers, which can lead to accidents. By giving drivers adequate notice of the changes, these signs contribute to smoother traffic flow and minimize the risks associated with transitioning into a work zone.
