Identify which approach is being stopped
An authorised traffic officer controls traffic even when the instruction differs from the ordinary sign or light. Reduce speed, look at the officer and establish whether the gesture is directed at your approach. Do not move merely because vehicles on another approach are being waved through.
The manual illustrates a stop signal to traffic approaching the officer from the front, a stop signal to traffic approaching from behind, and a simultaneous stop to traffic from the front and rear. In each case, judge your position relative to the officer, stop clear of the controlled area and wait for your approach to be released.
- Front-stop illustration: drivers approaching the officer’s front must stop.
- Rear-stop illustration: drivers approaching the officer’s back must stop.
- Front-and-rear stop illustration: both those approaches must stop; do not infer permission from facing away from the officer.
A wave applies to the approach being released
The two proceed illustrations on the right show the officer beckoning a stream of traffic to proceed. Establish that the movement is intended for you, check that pedestrians and other traffic are clear, then proceed as directed.
Keep watching for the next instruction while entering the controlled area. If the gesture is unclear, remain stopped in a safe position rather than guessing from the movement of an unrelated stream.
Stop, proceed and warning are distinct
A flag held out horizontally is the stop instruction shown in the manual. Stop before reaching the controller and wait. A flag waved down to signal proceed releases the controlled stream; move only after confirming that the controller is addressing you and the route is clear.
A flag waved up and down is a warning to reduce speed and proceed cautiously. It does not cancel a separate STOP sign, red signal or closed-road barrier. Expect workers, machinery, a queue or another hazard beyond the controller.
- Held horizontally: stop.
- Proceed wave: pass the control when directed and safe.
- Warning wave up and down: slow and stay alert.
