When I took my driving lessons at Young Drivers of Canada, I learned many great driving tips. One of the most helpful I've used constantly is the S-Approach when making left turns.
With the S-Approach, “S” is definitely for safety. When many drivers make a left hand turn, they simply enter the intersection with their wheels turned to the left. The position of the car makes it difficult to see the traffic past the opposite left hand turners. But more importantly, the wheels of the car are facing left, so if the driver is rear ended, the car will be pushed into oncoming traffic – very unsafe.
With the S-Approach, the driver turning left turns the wheels of the car sharply to the left as they enter the intersection then straightens them as they ready themselves for the turn. This positions the car to the far left of the turning area, making it much easier to see oncoming traffic. Plus, in case of a rear-end collision, the wheels are pointing straight ahead, so the car would be pushed forward into the intersection, rather than into traffic driving in the opposite direction.
