What are the visibility requirements for a flagging station?

• A. Be clearly visible to oncoming traffic and stationed far enough ahead for heavy trucks to stop.
• B. Stand hidden from traffic.
• C. Stand behind a rock.
• D. Wear dark clothing.

Answer: (A)

Visibility is the key. A flagging station must be clearly visible to oncoming traffic so drivers can notice the flagger early and begin braking in time. It also has to be stationed far enough ahead to give heavy trucks the extra stopping distance they need. In practice, that means choosing an unobstructed spot where drivers have a clear line of sight and wearing bright, high-visibility clothing so the flagger stands out in all conditions. Positions where the flagger is hidden, behind a rock, or wearing dark clothing would significantly reduce visibility and increase the risk of a collision.
