Left Turn Lane
If a street has a left turn lane, you must use it when you turn left. To turn left from the street, signal and drive completely inside the turn lane. Don't stop halfway into the lane with the back of your vehicle blocking traffic. Turn only when it is safe.
You may drive across a center left turn lane.
Cars C and D have to make the left turns from the center left turn lane. Car C moves to the center left turn lane from the right. It has to watch for oncoming traffic while turning left. Car D moves to the center left turn lane from the corner and has to watch for cross traffic when it comes to that lane. When it completes its left turn it has to watch for oncoming traffic. Car E is making a right turn at a corner with a bike lane. It has to watch for bicycles and pedestrians.
