What should be the condition of the flagging sign when flaggers are actively managing traffic?

When flaggers are actively managing traffic, the flagging sign should be visible without obstruction. This ensures that drivers approaching the work zone can easily see and understand the signals being provided by the flaggers. Visibility of the flagging sign is crucial for safe and effective traffic control, as it communicates important information to motor vehicle operators, helping them to react appropriately to the conditions of the road and the presence of the work zone.

An unobstructed view of the flagging sign allows for prompt recognition of any changes in traffic pattern, instructions, or warnings that are critical to maintaining safety for both the workers and the drivers. If a flagging sign is obstructed or not clearly visible, it can lead to confusion, increased risk of accidents, and violations of traffic control protocols, emphasizing the importance of keeping these signs in clear sight while flaggers are on duty.
