Flagging in Emergencies

Flagger sign side of the road

In emergencies, the following equipment and procedures may be used on a short-term temporary basis. However, provide standard traffic control as soon as possible.

If the STOP/SLOW paddle is not available, use a good-quality red flag to regulate traffic in emergency situations.

The flag shall have the minimum:

  • dimensions of 24 inches by 24 inches (600 mm by 600 mm),
  • minimum 3-foot (0.9 m) handle,
  • free edge of the flag should be weighted so the flag will hang vertically even in windy conditions.

A flashlight with a red glow cone may be used in addition to the red flag. Retroreflectorized clothing shall be worn.

Follow the procedures for stopping and releasing traffic under Two-Flagger Operations.
