Whenever a driver is facing a green signal they are free to enter an intersection. Drivers wanting to make a left turn must yield to all oncoming traffic. A driver facing a green signal and wanting to make a left turn may wait within the intersection to do so and then proceed when it is safe.

GREEN ARROW—A green arrow means GO, but first you must yield to any vehicle, bicycle, or pedestrian still in the intersection. The green arrow pointing right or left allows you to make a protected turn; oncoming vehicles, bicycles, and pedestrians are stopped by a red light as long as the green arrow is lit.

An unprotected left turn (no green arrow, but solid green light) must yield to oncoming traffic. Proceed to the middle of the intersection on the green light and wait with your tires straight (in case of a rear end collision you will not be pushed into oncoming traffic) until the way is clear for you to turn.

Vehicles turning left must always yield to oncoming traffic unless they have a turn signal. Similarly, vehicles turning left from a driveway, adjoining street, or parking lot must yield to vehicles turning left from the flow of traffic.

In the U.S., 38 states allow left turns on red only if both the origin and destination streets are one way as of December, 2018. Five states, namely Alaska, Idaho, Michigan, Oregon and Washington, allow left turns on red into a one-way street, even from a two-way.

You must STOP and wait until the light turns green. If there is not a “Green Arrow” traffic signal and there is a LEFT TURN YIELD ON GREEN sign, you need to move forward safely to the middle of the intersection and wait until oncoming traffic is fully clear, and it is safe for you to turn left before making the turn.

30×36 / Diamond Grade – $ 118.00. A Left Turn Yield on Green sign informs drivers that even though the light is green, they must yield to oncoming traffic before turning. So vehicles coming in the opposite direction at the light will have the right away.

You must wait for approaching traffic to go through before you turn. You can enter the intersection, however, to prepare for your left turn if the light is green and no other vehicle ahead of you is preparing for a left turn. When you enter the intersection, stay to the right of the center line.

Sometimes there will be dangers on both sides of the road at the same time. For example, there will be parked cars on the right and oncoming cars to the left. In this case, the best thing to do is “split the difference.” Steer a middle course between the oncoming cars and parked cars.

If you are turning left from a two-way street onto a one-way street, you should complete the turn into the lane closest to the lane you have just left.

And of course, only once the intersection is clear and you’ve come to a complete stop. As when turning right on a red light, drivers making a left on red must yield right-of-way to traffic in the intersection or approaching it. You cannot turn left on red from a one-way street onto a two-way street. You.

Turn into the lane that will interfere the least with traffic. If you are turning onto a one-way street, enter into the lane that interferes the least with other traffic. Do not make a dangerous turn into traffic.

Drivers also can make a left turn onto a one-way street, unless a posted sign prohibits the movement. The same rules apply: First, come to a complete stop at the red light, and give the right of way to other vehicles in or approaching the intersection. For many drivers, this maneuver seems odd.

You may turn left onto a one-way street that moves to the left if there is no sign prohibiting the turn.

The highway code states that if you find yourself going the wrong way down a wrong way street, you must not turn around but instead carefully proceed to the end.

15 mph

You may turn left into a left-moving, one-way street if there is no sign to prohibit the turn. Yield to pedestrians, bicyclists, or other vehicles moving on their green light.
