Rule Traffic controller signals take priority over traffic lights and road signs. Explanation If a traffic controller is present at an intersection, follow only their gestures. "Stop" means you stay put, even if the light is green. If permitted — proceed in the indicated direction. For example: if the controller faces you with their chest or back, movement is prohibited. In this case, the motor car driver is prohibited from driving in the arrow direction. Tip Slow down in advance, watch the controller's body and hands, and listen for the whistle. If the signal is unclear, stop at the stop line and wait for a clear command.
