When you turn left in the US, you yield. The left-turning driver gives way to oncoming traffic going straight or turning right, and to pedestrians crossing the street you are turning into. A circular green light lets you turn, but it does not give you priority: only a green arrow makes the turn protected. This guide uses the New York and California handbooks to show how the rule works on the permit test and the road test.
Key facts
- Turning left = you yield to oncoming vehicles going straight or turning right (New York, California and Oregon all teach this).
- Green circle: you may turn, but only after yielding to oncoming traffic and pedestrians.
- Green arrow: a protected turn, because oncoming traffic is held at red (California).
- Flashing yellow arrow: turn only after yielding to oncoming traffic (California).
- Wheels straight while you wait, so a rear-end crash can’t push you into oncoming traffic (California).
- Not sure the gap is big enough? Wait. No handbook penalizes a safe wait; many road tests penalize a forced turn.
Who has the right of way when turning left?
Oncoming traffic does. New York’s intersections chapter puts it this way: a driver turning left yields to an oncoming driver going straight or turning right. Oregon law also requires a left-turning driver to yield to oncoming traffic until the turn is safe. California’s handbook tells you to give the right-of-way to any pedestrian or approaching vehicle close enough to be dangerous.
The rule holds even when you got to the intersection first and even when your light is green. US law names who must yield; it doesn’t hand anyone an absolute right to go. California adds that you should give up your right-of-way when that helps prevent a collision, and never assume other drivers will yield to you.
Left turns at traffic lights: what each signal means
| Signal | Can you turn left? | Who yields |
|---|---|---|
| Circular green | Yes, when there is a safe gap | You yield to oncoming traffic and to pedestrians. California: “Pedestrians have the right-of-way.” |
| Green arrow | Yes, protected | Oncoming traffic is stopped. Still check for red-light runners and pedestrians finishing their crossing. |
| Flashing yellow arrow | Yes, after yielding | You yield to oncoming traffic and pedestrians. It works like a circular green. |
| Steady yellow (circle or arrow) | Only if you can’t stop safely | The signal is about to change. Don’t speed up to beat it. |
| Red (circle or arrow) | No, with one exception | California allows a left on red from a one-way street onto another one-way street, after stopping, if no sign prohibits it, and after yielding to anyone with a green light. |

How to make a left turn, step by step
- Get into position early. Move close to the center line, or into the left-turn lane at its opening. California says not to cross a solid line to get into the lane.
- Signal at least 100 feet before the turn (California) and check your left mirror and blind spot.
- If you must wait, stop at the right spot. At a signal, the New York road test marks you down for not stopping near the center of the intersection when waiting to turn left. Stop behind the line when the intersection ahead is full.
- Keep your wheels pointed straight. California warns that if your wheels point left and someone hits you from behind, you could be pushed into oncoming traffic.
- Judge the gap. Look left, right, then left again. Check the crosswalk you are turning into.
- Turn into the correct lane. From a two-way street onto a two-way street, finish in the lane closest to the middle of the road (California). From a one-way street, start from the far-left lane.
- Accelerate smoothly and let the steering wheel straighten in the new lane.
Five left-turn traps that cause crashes and test fails
1. The oncoming driver with a right signal on
California’s handbook says don’t assume an oncoming vehicle with its right signal on will turn before it reaches you. Wait until it actually starts turning.
2. The car hidden behind the turning car
An oncoming vehicle that turns out of your path can reveal another one behind it, often going faster. Look past the first vehicle before you commit.
3. Your view blocked by an opposing left-turner
When a car facing you is also waiting to turn left, it can hide the lane beside it. If you can’t see that lane, you can’t judge the gap. Wait, or creep forward only as far as you need to see.
4. Motorcycles and bicycles
They are small and their speed is hard to judge. Look twice before turning left. California also notes that cyclists can legally use the left-turn lane for their own left turns. See sharing the road with motorcycles, bicycles and trucks.
5. Pedestrians in the crosswalk you are turning into
Drivers focused on oncoming cars often miss people crossing the side street. You must yield to them, even when you have found a gap in traffic. See pedestrians and crosswalks.
Left turns into and out of driveways and parking lots
- Turning left into a driveway crosses oncoming traffic, so the same rule applies: oncoming traffic and pedestrians on the sidewalk go first. California allows a left turn into a driveway across double yellow lines, and New York’s manual allows crossing double solid lines to turn left to enter or leave the highway. Check your state’s handbook and US pavement markings.
- Turning left out of a driveway, alley or parking lot means yielding to everyone already on the road in both directions, and to pedestrians on the sidewalk first. Details in right of way at uncontrolled intersections, T-junctions and driveways.
- On a road with a center turn lane, California says to enter the two-way left-turn lane within 200 feet of your turn. See center two-way left-turn lanes.
Left turns at stop signs and uncontrolled intersections
- All-way stop: the first to stop goes first. If you and an oncoming car stop together and you are turning left, the oncoming car going straight goes first. See four-way stops explained.
- No signs at all: first to arrive goes first, and yield to the right on a tie. Turning left, you still yield to oncoming traffic.
- Roundabouts: there is no left-turn conflict. You go around counterclockwise and yield on entry. See how to drive a roundabout in the US.
What the road test examiner watches on a left turn
- Signaling early and checking mirrors and the blind spot.
- Correct lane position before and after the turn. Turns that are too wide or too short lose points on the New York road test.
- Where you wait, and that your wheels stay straight.
- Yielding to oncoming traffic and pedestrians. Forcing another driver to brake is a serious error in most states. See common reasons people fail the US driving test.
- Not hesitating when the gap is clearly safe. Waiting through obvious gaps can also cost marks.

Practice questions: left turns
These are unofficial practice questions written by Get Driving Test Ready. They test the same knowledge as US permit tests but don’t use official question wording.
1. Your light is a circular green. You want to turn left, and an oncoming car is going straight. What should you do?
- A. Turn first, because your light is green
- B. Sound your horn and turn
- C. Let the oncoming car pass, then turn when there is a safe gap
- D. Turn quickly before the car reaches the intersection, whatever the distance
Answer: C. A circular green allows the turn but doesn’t protect it. Left-turning drivers yield to oncoming traffic (handbook topic: intersections and turns).
2. A flashing yellow left-turn arrow means:
- A. Turn left after yielding to oncoming traffic and pedestrians
- B. Left turns are prohibited
- C. The turn is protected; oncoming traffic has a red light
- D. Stop and wait for a green arrow
Answer: A. The flashing yellow arrow permits the turn after yielding (handbook topic: traffic signals).
3. While you wait to turn left across traffic, your front wheels should be:
- A. Turned left, ready to go
- B. Pointed straight ahead
- C. Turned right, toward the curb
- D. It doesn’t matter
Answer: B. If you are hit from behind with your wheels turned left, you can be pushed into oncoming traffic (handbook topic: turning left).
4. An oncoming car has its right turn signal on. You want to turn left. What is the safest choice?
- A. Turn now, because the car will turn right
- B. Flash your headlights and go
- C. Go if the car is slowing at all
- D. Wait until the car actually starts its turn
Answer: D. A signal shows intent only. The driver may go straight (handbook topic: turning left).
5. You are turning left from a one-way street onto a two-way street. Which lane should you start from?
- A. Any lane, if you signal
- B. The far-left lane
- C. The far-right lane
- D. The center lane
Answer: B. Start left turns from a one-way street from the far-left lane (handbook topic: turning left).
6. You are turning left on a green arrow. A pedestrian is still finishing a crossing in the street you are entering. What should you do?
- A. Continue, because the arrow is protected
- B. Swerve around the pedestrian
- C. Yield and let the pedestrian finish crossing
- D. Sound the horn so they hurry
Answer: C. A protected arrow stops oncoming cars, but you must still yield to pedestrians in the crosswalk (handbook topic: pedestrians and right of way).
7. You are turning left into a driveway across a lane of oncoming traffic. Who goes first?
- A. Oncoming traffic, then pedestrians on the sidewalk, then you
- B. You, because you signaled
- C. You, because driveways have priority
- D. Whoever is faster
Answer: A. A left into a driveway crosses traffic, so you yield to oncoming vehicles and to people on the sidewalk (handbook topic: right of way).
8. When may you turn left on a red light in California?
- A. Never
- B. From any street, after a full stop
- C. From a one-way street onto another one-way street, after stopping, if no sign prohibits it
- D. Only on a red arrow
Answer: C. California allows this one case, after a stop and after yielding to traffic and pedestrians with a green light. Other states have their own rules (handbook topic: traffic signals).
More practice: US permit practice tests, including the New York and California sets.
Common questions
Does turning left on green mean I have the right of way?
No. A circular green lets you turn, but you yield to oncoming traffic going straight or turning right, and to pedestrians. Only a green arrow makes the turn protected.
Who goes first: left turn or right turn, when cars face each other?
The right-turning car. The left-turning driver yields to oncoming traffic going straight or turning right.
Can I wait in the middle of the intersection to turn left?
At a signal, yes, when the space is clear. New York’s road test expects you to wait near the center of the intersection. Don’t enter if the far side is blocked and you would be stuck when the light changes.
What if the light turns red while I am waiting in the intersection?
Finish the turn once oncoming traffic stops, clearing the intersection with care. You entered legally, so complete the turn safely rather than stopping in the middle.
Is a “Pittsburgh left” or any local left-first habit legal?
Not under the yield rule in state handbooks. Don’t turn left in front of oncoming traffic because a local habit says you can, and never do it on a road test.
Is the left-turn rule the same in every state?
The basic yield rule is the same in the handbooks checked here. Details differ, such as left on red, center turn lanes and whether you may cross double yellow lines. Check your own state’s manual through learning to drive in the USA.
