What is the purpose of advance warning signs?

• A. To alert motorists of upcoming work areas.
• B. To provide shelter for workers.
• C. To indicate detours only during emergencies.
• D. To speed up traffic through the work zone.

Answer: (A)

Advance warning signs are there to alert drivers that a work area lies ahead, giving them time to slow down, merge if needed, and follow detour guidance. This early notice helps create a safer buffer for workers and equipment and reduces the chance of crashes by promoting a controlled approach to the work zone. They aren’t for sheltering workers, aren’t limited to emergencies, and aren’t meant to speed traffic; instead, they encourage reducing speed and driving with extra caution as you approach the area.
