Single-Flagger Operations
A single flagger can be used when:
Sight distance is adequate
Traffic volume is low (less than 2,000 vpd)
Work zone length 100 feet (30 m) or less.
Releasing Traffic
- Return to the shoulder of the road with the STOP side toward stopped vehicles.
- Turn the paddle so neither STOP nor SLOW can be read by drivers approaching from either direction. Take care not to confuse continuous traffic traveling in the other lane in the opposite direction.
- Motion for traffic to proceed.
A second flagger shall be added when these conditions change or when traffic conflicts and delays become excessive.
