INTERSECTIONS
Nearly one third of all collisions happen at intersections. In order to make certain that no one is running the red, you should scan left, centre and right before proceeding on a fresh green or when approaching every intersection. Red lights and stop signs only stop drivers who see them. Be sure it is safe before entering an intersection.
LEFT TURNS AT TRAFFIC LIGHTS
Turning left in front of oncoming vehicles on a green light is one of the most dangerous maneuvers you will ever perform. The view of oncoming cars may be blocked by approaching left turning vehicles, blinding rain or snow and still drivers turn. When the light turns amber many drivers gamble and complete the turn hoping they won't be hit. Avoid the danger. Instead of turning left in bad weather, go through the intersection and make 3 right turns to get around the block and onto the intended street in complete safety.
WHEELS STRAIGHT FOR LEFT TURN
When waiting to make a left turn at an intersection you should come to a stopped position with your wheels pointing straight ahead. If you notice that a vehicle is coming up too fast from behind then you have the opportunity to drive straight through the intersection and avoid being hit from behind.
