The Traffic Safety Act 235 - Traffic lights
Note: Most cases involving red light infractions usually involve both drivers being adamant that they had a green light. It is difficult for the court to decide without independent witness evidence or expert evidence regarding how the damages to the vehicles would have occurred.
Subject to subsection (6), if a traffic light at an intersection displays only a red light: the driver of a vehicle facing the light shall stop at the intersection;
How the rule is applied
When approaching a red light, you must stop and remain stopped until the light changes. When approaching a green light, you may turn left, right or drive straight through the intersection unless a sign prohibits any of these movements. If you want to turn left you can enter the intersection on a green light, but you must yield to oncoming traffic and pedestrians. If traffic is heavy, you may be forced to complete your turn on an amber or red light.
