What is the last sign that should be set up in a construction zone?

The last sign that should be set up in a construction zone is the "End Road Work" sign. This sign signals to drivers that they have exited the construction area and can expect to resume normal driving conditions. It is crucial for ensuring that motorists are clearly informed when the active construction zone has concluded, thus enhancing safety and reducing confusion.

The placement of the "End Road Work" sign allows for a smooth transition as vehicles move away from construction activities, helping to eliminate any lingering uncertainty about road conditions. Drivers rely on this clear indication to understand that they have returned to standard road rules and conditions, preventing any potential hazards associated with lingering construction notifications.

Understanding the role of these signs is essential for flaggers, as it ensures that drivers are provided with timely and appropriate information to navigate construction zones safely.
