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.
