Left turns: Don't try to turn left from the right lane. Before getting to the intersection, signal and move into the left lane when possible. Position yourself so that it is not possible for a car to pass you on the left when you are trying to turn left. Yield to oncoming vehicles before turning. If traffic is too busy or it's unsafe to turn left, proceed through the intersection from the right, stop and get into the bike lane and proceed when the light changes, or walk across the corsswalk.
