Unless signs or pavement markings tell you not to, always begin and end a left turn in the far left lane in your direction.
To make a left turn, signal well before the turn and move into the far left lane when the way is clear. Look ahead, behind, left, right and left again and check your blind spots. Make your turn when the way is clear.
When you are stopped at an intersection waiting for approaching traffic to clear, don't turn your steering wheel to the left until you can complete the turn. With your wheels turned to the left, your vehicle could be pushed into the path of oncoming traffic.
When two vehicles coming from opposite directions meet in an intersection waiting to turn left, each should turn to the left of the other after yielding the right-of-way to pedestrians and oncoming traffic.
Motorcycles, bicycles, limited-speed motorcycles and mopeds turn left at intersections in the same way as larger vehicles. If you are making a left turn behind one of these vehicles, do not pull up beside it to make your turn at the same time. Stay behind and turn when the way is clear. Wait for the smaller vehicle to move right before you pass.
The following diagrams show you the correct way to turn left on different types of roads:
Diagram 2-25: Two-way road to a two-way road.
Turn from the lane closest to the centre line to the lane right of the centre line, following a smooth arc. Then, when you can, move into the right curb lane.
Diagram 2-26: Two-way road to a one-way road.
Turn from the lane closest to the centre line to the left curb lane.
Diagram 2-27: One-way road to a two-way road.
Turn from the left curb lane to the lane just right of the centre line. Then, when you can, move into the right curb lane.
Diagram 2-28: One-way road to a one-way road.
Turn from the left curb lane to the left curb lane.
