Don't start your left turn until you've reached the center of the intersection. Because of off-tracking, your vehicle's rear wheels follow a shorter path than the front wheels. If you start your left turn before you reach the center of the intersection, the left side of your vehicle may hit another vehicle. Another tip: If there are two left-turn lanes available, use the one on the right. You may not have enough room to turn left from the leftmost turn lane without swinging right. If you swing right, another driver may try to pass you on your left as you are turning.
