Understanding Left Turns with a Green Light: 1 Minute to Improve Your Driving Safety

Turning left at an intersection with a green light seems straightforward, but it involves important rules and safety considerations that every driver should understand. When you approach an intersection with a green light and want to make a left turn, you do not automatically have the right-of-way. Instead, you must yield to oncoming traffic, as well as pedestrians crossing in the crosswalk. A steady green light allows you to proceed, but only when it is safe to do so. You should move into the intersection and, when there is a clear gap in oncoming traffic and no pedestrians in the crosswalk, complete your left turn. If the light turns yellow or even red while you're in the intersection, you should finish your turn promptly and safely. Remember, a green arrow is different—it gives you the right-of-way to turn left without yielding to oncoming traffic or pedestrians (except those lawfully in the intersection).

Tips 1:

As a designer and visual planner, I recommend thinking of intersections much like key junctions in a home layout—flow, visibility, and right-of-way must be clear to avoid accidents and confusion. In complex spaces or high-traffic areas, tools like a floor planner can help visualize and optimize traffic patterns, a mindset that also applies to city streets and intersections for optimal safety and clarity.

FAQ

Q: Who has the right-of-way when turning left with a green light?

A: Oncoming traffic and pedestrians have the right-of-way. The turning vehicle must yield.

Q: What should I do if the light turns yellow while I'm waiting to turn left?

A: If you are already in the intersection, complete your turn safely when traffic allows.

Q: Is it legal to enter the intersection while waiting for a gap when turning left?

A: Yes, it is legal (and recommended) to enter the intersection when you intend to turn left and are waiting for a safe gap.

Q: What is the difference between a green arrow and a green light for left turns?

A: A green arrow gives you the right-of-way to turn left without yielding to oncoming traffic; a green light means you must yield first.

Q: Are pedestrians allowed to cross during your left turn at a green light?

A: Yes, if they have a “walk” signal or green light, pedestrians can cross, and drivers must yield to them.
