3.5 Traffic Signals
Traffic signals are electronic devices positioned at intersections and pedestrian crossings to manage the flow of traffic safely. It is crucial to understand and obey them.
A. Vehicle Traffic Lights
This is the standard, three-colour traffic light.
- Green: You may proceed, but only if it is safe. You must still yield to pedestrians and emergency vehicles. If turning right, you must also yield to oncoming traffic.
- Amber (Yellow): This means STOP before the stop line. You may only proceed if you are too close to the intersection to stop safely. It is a warning that the light is about to turn red.
- Red: You must stop completely behind the stop line and wait for the light to turn green.
- Green Filter Arrow: If a green arrow is lit (on its own or with a red light), you may proceed cautiously in the direction of the arrow, even if the main light is red. You have the right of way over conflicting traffic.
B. Flashing Lights
- Flashing Red Light: This has the same meaning as a STOP sign. You must stop completely and only proceed when it is safe.
- Flashing Amber (Yellow) Light: This is a warning to proceed with caution. Slow down and be aware of potential hazards.
3.6 Hand Signals
Hand signals are a form of communication on the road used by traffic officers, drivers, and cyclists. You must be able to understand and, when necessary, use them.
A. Signals by a Traffic Officer
Signals given by a uniformed traffic officer overrule all other signs and signals. You must obey them.
- To Stop Traffic from the Front: The officer will face you and raise their hand with the palm facing you.
- To Stop Traffic from the Front and Back: The officer will extend both arms sideways, level with their shoulders, with palms facing forward.
- To Stop Traffic from the Back: The officer will extend their right arm out from their shoulder with the palm facing you.
- To Signal Traffic from the Front or Side to Proceed: The officer will beckon you forward with a swinging motion of their arm.

B. Hand Signals by Drivers and Cyclists
While modern cars have indicators, you are still required to know the hand signals, especially if your indicators fail. They are also essential for understanding the intentions of cyclists.
- To Stop or Reduce Speed Suddenly: Extend your arm out of the window with your forearm pointing downwards and your palm open and facing backward.
- To Turn Right: Extend your arm straight out of the window, horizontally, with your palm facing forward.
- To Turn Left: Extend your right arm out of the window and rotate it from the shoulder in an anti-clockwise direction.
