Work zones change the road without warning: lanes close, workers step out, traffic stops. Orange means construction, and in a work zone the flagger's directions outrank every sign and signal.

Know the rule

Orange flags and signs indicate a "high hazard area" (maintenance and construction).

Handbook p. 31 ↗

Know the rule

Construction and maintenance signs are black on orange. They mark work in the road and temporary conditions; adjust your speed and prepare for special conditions.

Devices that guide you through work zones:

  • Barricades, vertical panels, cones, tubes and drums; at night they often have flashing or steady lights
  • Large flashing or sequencing arrow panels, used day and night

Work-zone signs also tell you to:

  • Prepare to stop for a flagger ahead
  • Be alert for a crew working on or next to the roadway
  • Follow the detour to the right in front of the sign
Handbook p. 46 ↗

Put it into practice

A flagger holds up a STOP paddle, but the traffic light beyond the work zone is green. Stop. A flag person's directions take priority over the signal.
