Flaggers are the first line of defense in keeping vehicles out of the work zone. But if flagging is done improperly, it can confuse drivers and endanger everyone on site.
Why It Matters:
Improper flagging increases the risk of driver error, work zone intrusions, and worker injuries. Flaggers must be trained, visible, and positioned for maximum effectiveness.
Key Points:
- Only trained and authorized workers should serve as flaggers.
- Wear ANSI Class 2 or 3 high-visibility apparel, including reflective vest and hard hat.
- Use the proper paddle (STOP/SLOW) — not hand gestures or improvised tools.
- Stand where you’re clearly visible, never in the path of moving vehicles.
- Maintain eye contact with drivers and use firm, clear hand signals.
- Coordinate with other flaggers using radios or pre-agreed hand signals.
✅ A confident, visible flagger keeps traffic flowing and workers protected.
Ask the Crew:
- Who is designated to flag traffic today?
- Are we all clear on signals and radio channels?
