Left-turn and intersection crashes: right-of-way and fault

When a left-turning car and an oncoming car collide, the turning driver is usually found mostly or fully at fault, because the law makes the turner yield to oncoming traffic that is close enough to be a hazard. That default changes when the oncoming driver ran a red light, was speeding, or entered after the signal was clearly against them, or when the turner had a protected green arrow. In many cases fault ends up split.

What follows is how right-of-way works at signals, stop signs and uncontrolled intersections, where the disputes come from (yellow lights, blocked views, arrows), what evidence settles them, and how your own coverage works while the argument continues.

The basic rule: the turner yields

State vehicle codes differ in wording but nearly all contain the same core duty. In Texas, Transportation Code section 545.152 says a driver turning left at an intersection, or into an alley, private road or driveway, must yield the right-of-way to a vehicle approaching from the opposite direction that is in the intersection or close enough to be an immediate hazard. Michigan's rule, MCL 257.650, is to the same effect, and it makes a violation a civil infraction.

The words that matter are "close enough to be an immediate hazard." They turn the yield rule into a question about distance and speed. If the oncoming car was a block away at a legal speed, the turner could go. If it was fifty yards off at a speed that gave no time to stop, the turner could not. So the first fight is almost always about how far away the oncoming car was and how fast it was going.

The other driver has duties too: obeying the signal, keeping a lawful speed, keeping a lookout, and braking when a collision is foreseeable. A driver with the right-of-way is still expected to avoid a crash if they reasonably can. That is why many left-turn collisions are not 100/0.

Angle crashes, a category that includes many intersection collisions, are not rare. In 2023, the Insurance Information Institute's tabulation of federal data counted 7,044 fatal angle crashes, 18.7% of the 37,654 fatal crashes by first harmful event (III). That figure counts only fatal crashes and does not separate left turns from other angle crashes, so it should not be read as "left turns cause 18.7% of crashes."

Protected and permissive turns

The signal controls who has priority.

Disputes happen when drivers do not know which phase they are in. Intersections with a left arrow that turns off, "protected-permissive" signals that show an arrow then a solid green, and flashing yellow arrows that appear in some places and not others all produce confusion. A turner who thought they had a protected arrow when they had a flashing yellow arrow still bears the yield duty. The signal's actual status at the moment of the crash is a fact that can be checked, and it is usually decisive.

When a green arrow is displayed and an oncoming driver runs a red light into the turning car, the oncoming driver is at fault for the crash. It may seem obvious, but it is exactly the case where each driver says they had the green.

Yellow lights and the "I entered legally" argument

Yellow-light cases are some of the hardest to resolve. In general, state laws let a driver enter an intersection on yellow and require stopping only if it can be done safely, but details differ, and a few places have stricter statutes. Your state's vehicle code is the source.

Typical disputes:

• The oncoming driver says the light was yellow when they entered; the turner says it was red. Both may be right: the light changed while the oncoming car was approaching, and the turner began a turn on the assumption that oncoming traffic would stop.
• The turner started on green and was still in the intersection when it changed. Drivers waiting in an intersection to turn when the light turns red are generally expected to complete the turn once oncoming traffic has stopped, and oncoming drivers must wait for the intersection to clear. If the oncoming car entered late on red, the oncoming driver carries most of the fault.
• The turner rushed through on yellow in front of an oncoming car that had a green. The turner is at fault; the signal change does not restore the right-of-way against a car that has entered lawfully.

Because the timing of yellow and all-red intervals is set by traffic engineers and recorded by the controller, the disputed facts can often be checked rather than argued. The signal controller keeps phase and timing information, but the records may be kept only for a limited time. Some agencies will keep data if you ask early. This is one of the few situations in which a prompt written request to the city or county traffic department matters.

Four-way stops, two-way stops and uncontrolled intersections

Not every intersection has a signal.

All-way stops. The first driver to stop and arrive goes first. If two arrive at the same time, the driver on the right goes first in most states. A driver turning left yields to an oncoming driver going straight when both arrive together. The common mistake is a rolling stop: a driver who does not fully stop cannot claim to have arrived first.

Two-way stops. The driver facing the stop sign yields to cross traffic, whether turning or going straight. If a driver turning left from the through road collides with a stopped driver who pulled out, the stop-sign driver typically carries most of the fault, though the through driver must still avoid a foreseeable crash.

Uncontrolled intersections (no signs or signals). Drivers yield to a vehicle already in the intersection, then to the vehicle on the right. A left turner yields to oncoming traffic.

Driveways, alleys and parking lots. A driver entering a road from a driveway must yield to traffic on the road. A left turn into a driveway is still a left turn; the turner yields. Collisions inside lots follow different patterns, covered in parking lot and private property accidents: fault and reporting.

Obstructed views

A common crash: two left-turn lanes face each other. Cars waiting in them block each other's view of oncoming through traffic. A turner creeps across the gap and is hit by a car in the through lane that could not be seen.

The turner still carries the duty to yield. Courts and insurers do not usually accept "I could not see" as an excuse, since a turner who cannot see should not go. Still, fault may be shared if the oncoming driver was speeding or inattentive, or if a large vehicle shielded both drivers. The oncoming driver also has a duty to watch for turning cars at an intersection and to slow when cars are waiting to turn.

The fix many traffic agencies use is offsetting the turn lanes or changing to a protected phase. For you, the useful point is practical: if your view is blocked, wait for a clear gap, or edge forward only enough to see.

How comparative fault splits the result

How fault is divided depends on the state's negligence rule. The guide to comparative and contributory negligence lays out the systems, and modified comparative negligence: how the 50 and 51 percent bars work explains the bars. In brief:

• Pure comparative: your recovery is reduced by your share of fault, with no cutoff.
• Modified comparative: you recover nothing if your share reaches 50% or 51%, depending on the state.
• Contributory: in a handful of jurisdictions, including Alabama, Maryland, North Carolina, Virginia and the District of Columbia, fault of any amount by you can bar a claim against the other driver.

A worked example, with invented numbers. Say you turn left on a flashing yellow arrow and an oncoming SUV, traveling about 15 miles per hour over the limit, hits the right side of your car. Your repair estimate is $9,200, the SUV's is $6,400, and your medical bills are $4,000.

A reconstruction concludes the SUV driver was speeding and could have braked earlier, but you did not leave a safe gap. The insurers agree on 75% to you and 25% to the SUV driver.

• Your claim against the SUV's driver: 25% of your $9,200 car damage is $2,300, and 25% of your $4,000 medical bills is $1,000.
• The SUV driver's claim against you: 75% of $6,400 is $4,800, plus any injuries.

In a state with a 50% or 51% bar, your 75% share would bar your claim against the SUV driver altogether, while their claim against you would go forward, reduced by their own 25%. In a contributory state, any share on your part would bar your claim. In a pure comparative state, the percentages apply as shown. If you have collision coverage, your own insurer repairs your car regardless, less your deductible, and may then recover from the other insurer in proportion to its share of fault. Your payment is the same under each state's rule, but the other insurer's contribution is not.

What physical evidence is used

Left-turn collisions leave good evidence, which is why careful reconstructions can settle disputes.

• Impact points. A turning car is typically struck on its side or front corner by the oncoming car's front. If the oncoming car's front hits the turner's rear quarter, the turner had mostly cleared the lane, which suggests the oncoming driver arrived late or did not slow.
• Crush depth and rest positions. Deep damage and long travel after impact imply higher speed.
• Skid and yaw marks. They show whether the oncoming driver braked before impact and how hard.
• Vehicle data. Speed and braking before impact are stored in many cars. See event data recorders: what your car records and who can access it.
• Signal timing records. Phase sequences and timing from the controller, if kept, show which signal each approach had.
• Cameras. Red light cameras, traffic cameras, businesses and dashcams. Footage is often overwritten in days. dashcam footage and scene evidence: what to capture and keep covers asking for and preserving it.
• Witnesses. Drivers waiting at the light behind each car are valuable.
• 911 and dispatch records. Timing of calls can match the video.
• Police report. The report notes citations, which are treated as evidence of fault by many insurers, though a ticket is not proof of liability, and paying one may be treated differently from contesting it. See do you need a police report after a car accident?.

Steps after an intersection crash

1. Check for injuries and call 911.
2. Photograph the signal heads, signs and approach lanes for each direction, showing what each driver saw.
3. Photograph vehicle positions, damage and skid marks before cars move.
4. Note the signal phase you saw, in writing, as soon as you can.
5. Look for cameras facing the intersection (traffic, stores, buses) and write down which businesses have them.
6. Get witnesses' names and phone numbers.
7. Use the after-accident checklist and information form to record driver, plate and insurer details.
8. Ask police whether a citation was issued, and ask for the report number.
9. Report to your insurer quickly and ask in writing for the claim number and adjuster.
10. If fault is disputed, send the adjuster your photos and any footage. how to contest your insurer's decision that you were at fault covers a challenge to a fault ruling.

Common questions

If I was turning left and got hit, is it always my fault?

No, but you start from a weaker position. You can reduce your share with evidence that the other driver ran a light, was speeding, or entered the intersection after it was clearly unsafe, or that you had a protected arrow.

What if the other driver says their light was green and so does mine?

Both lights cannot be green in the same phase unless the signal malfunctioned or one driver is mistaken. Cameras, signal timing records, witnesses and the crash damage can settle it. If no evidence exists, insurers often split fault.

Does a ticket decide fault?

Not by itself. Insurers consider a citation, but they run their own investigation, and fault is decided under the state's rules. Whether a ticket or a guilty plea can be used in a later civil case varies by state.

Do motorcyclists get the same treatment?

The yield rule is the same, but the injuries are more severe, and a classic claim is that the turner "did not see" the motorcycle. That is not a defense. See car-motorcycle collisions: fault, injuries and claims.

Will a left-turn claim raise my rates?

If you are found at fault, an at-fault accident can add a surcharge, depending on your insurer and state. See how much one at-fault accident raises your rate in different states for how much.

Key takeaways

• A left-turning driver must yield to oncoming traffic that is in the intersection or close enough to be an immediate hazard, so the turner usually carries most of the blame.
• Exceptions include a red-light-running or speeding oncoming driver, a protected green arrow, and late entries after the signal changed. Fault is often split.
• Flashing yellow arrows, yellow-light timing and blocked views are the most common sources of disputes.
• Signal timing records, camera footage and vehicle data can settle the facts, but they are overwritten quickly. Ask for them early.
• Your state's negligence rule decides what a split means for payment. Your own collision coverage can pay without waiting for fault.
