Why are pavement markings critical in work zones?

Pavement markings play a crucial role in work zones primarily because they guide drivers and delineate lanes. In temporary conditions created by construction or maintenance activities, clear markings are essential for directing traffic safely through the area. They help control vehicle movements, ensuring that drivers understand which lanes to use and where to stop or yield. This guidance is vital since work zones often feature altered road layouts that can be unfamiliar to drivers.

While aesthetic appeal, informing pedestrians, and indicating maintenance schedules are important functions in different contexts, they do not fundamentally address the immediate safety needs of drivers navigating through work zones. Safety is the primary concern in these areas, and the effective use of pavement markings significantly enhances the overall safety and efficiency of traffic flow.
