What is the main role of the Stop/Slow paddle?

• A. To indicate speed limit changes.
• B. To direct pedestrians only.
• C. To communicate with road users and control their movements in the work zone.
• D. To measure traffic flow.

Answer: (C)

The Stop/Slow paddle is a flagger tool used to communicate with road users and control their movements in the work zone. It provides a clear, universally understood signal to drivers and pedestrians: when the paddle shows Stop, vehicles must halt; when it shows Slow, they should reduce speed to allow safe passage around workers or obstructions. This direct, in-person signaling is essential for coordinating movement through the work area and keeping workers safe. It isn’t about changing posted speed limits or measuring traffic flow, and it’s not limited to pedestrians—the paddle directs all approaching road users through the work zone.
