What should be done to the "FLAGGER AHEAD" sign when no flagging is taking place?

The appropriate action with the "FLAGGER AHEAD" sign when no flagging is taking place is to cover or remove it. This is crucial because the purpose of the sign is to inform drivers about active flagging operations ahead, which helps in managing traffic safely in work zones. When flagging is not occurring, leaving this sign in place could mislead drivers into expecting flaggers to be present, which could lead to confusion or unsafe driving behavior.

Covering or removing the sign helps to ensure that the information provided to drivers is accurate and current. This practice maintains the integrity of the traffic management system and enhances safety for both road users and workers. By doing so, it prevents potential accidents caused by drivers reacting to non-existent flagging, thus promoting a clear and effective communication strategy regarding road conditions.

Using a detour sign or leaving the sign as is would not effectively address the necessity for accurate informational signage, leading to possible complications for drivers navigating the work zone.
