A yellow light does not just simply permit drivers to intentionally drive through a yellow light. Traffic lights control the flow of vehicles and pedestrians to improve safety and access to roads. You should drive at a speed that gives you time to react if the traffic lights change. Many people may not be aware, but if you go through a yellow traffic light, you may receive an infringement notice as it is an offence. Yellow (amber) means stop. You can enter the intersection if you are so close that sudden braking might cause a crash. You may drive through a flashing yellow light or arrow with caution. You need to apply the give way rules to avoid colliding with other vehicles.
