Signals tell other drivers what you want to do, alerting them to your intention to turn or stop.
Use your turn signals and brake lights to signal before stopping, slowing down, turning, changing lanes, leaving the road or moving out from a parked position. Give the correct signal well before taking the action and make sure other drivers can see it. Check that the way is clear before you act, just signalling is not enough. Follow the rules for turns, whether left or right, on lane changes and on yields to other vehicles and pedestrians.
If your turn signals and brake lights are not working, use hand and arm signals. The pictures on the previous page show how to make hand and arm signals. When watching for signals made by others, remember that cyclists may signal right turns by holding their right arms straight out.
After signalling, move only when it is safe to do so.
