Flagger Problems
Flagging is done from an unsafe position, with unclear signals, without advance warning, or without coordination between flaggers.
Last reviewed: June 24, 2026
What It Looks Like
- A flagger positioned where drivers cannot see them in time, giving unclear signals, or with no flagger-ahead advance warning.
Why It Happens
- Flagging is used to compensate for an incomplete setup, or the flagger station and warning were not planned.
Why It Matters
- Flaggers stand next to live traffic; poor position, signaling, or warning endangers them and road users.
How It Is Identified
- An inspection checks flagger position, visibility, signaling, advance warning, and coordination.
How It Is Corrected
- Reposition the flagger for visibility and an escape path, add advance warning, and coordinate multiple flaggers.
How It Can Be Prevented Upstream
- Plan flagger stations and advance warning, and never use flagging to substitute for proper setup.
