Fault in an Illinois Motorcycle Accident After a Left Turn

Published: October 13, 2026

Fault in an Illinois motorcycle accident starts with the left-turn rule in 625 ILCS 5/11-902: the turning driver must yield to oncoming traffic close enough to be an immediate hazard. A jury weighs any violation with the other evidence and assigns each side a share of fault. Illinois courts keep an adult rider’s missing helmet out of the case.

A car turned left across your lane and you went down. The driver’s adjuster says you were going too fast and wore no helmet. This is the kind of case we take. You want to know whether this is on you. Start with the rule: a driver turning left must yield to an oncoming rider who is close enough to be an immediate hazard. The rest turns on the seconds before the turn, and the helmet stays out of it.

Who has to yield when a car turns left in front of a motorcycle in Illinois?

The driver turning left has to yield. Under 625 ILCS 5/11-902, a driver turning left at an intersection or into a driveway must yield to any oncoming vehicle close enough to be an immediate hazard. A motorcycle is a vehicle under that rule.

Turning across the path of a motorcycle that is close enough to be an immediate hazard breaks that rule. Whether the motorcycle was that close when the turn began is a question the evidence answers. In an Illinois injury case, a broken traffic rule is evidence of carelessness. A jury weighs it with everything else about the crash and decides each driver’s share of fault.

Our post on left-turn motorcycle crashes in Illinois covers what happens when the driver says “I did not see the motorcycle.”

The driver’s insurer says I was going too fast. Does speed decide fault in an Illinois motorcycle accident?

Speed is an argument about your share of fault, and the evidence decides it. The turning driver’s duty to yield sits alongside your own duty to ride with ordinary care. If the evidence shows your speed or lane position contributed to the crash, a jury may assign you a share of the fault. Fault is decided on what happened, and being on a motorcycle is no part of it.

Illinois uses a more-than-50-percent rule under 735 ILCS 5/2-1116. If a jury finds you more than 50 percent at fault, you recover nothing. If it finds you 50 percent or less at fault, you recover, and the award is reduced by your percentage.

The evidence that places you and the car when the turn began:

Where the car was hit, and where both vehicles came to rest.
Marks and debris on the road.
Camera footage, including a helmet camera if you ran one.
Witnesses who saw the car start its turn.

Together these help show where you were and how fast you were going when the car began its turn. Save scene photographs and witness names now.

Does it matter that I was not wearing a helmet?

Illinois courts have held that a missing helmet cannot be used against an adult rider in an injury case, either on fault or on damages. Illinois law requires no helmet for a rider or passenger of any age, so riding without one breaks no rule the law imposes. The rule rests on a 1985 Illinois Supreme Court decision and on appellate decisions from 1985 and 1991. As of 2026, no later Illinois decision has narrowed it.

The gear the law does require is eye protection under 625 ILCS 5/11-1404: glasses, goggles or a transparent shield. Contact lenses do not count. Our post on Illinois motorcycle helmet law and injury claims covers the court decisions and head injury proof.

The CDC’s motorcycle safety page, updated in January 2026, says helmets reduce the risk of head injury. In your claim, Illinois courts keep the helmet question out of the case.

What if I was riding between lanes when the car turned?

Expect it to be raised as part of your share of fault. Illinois does not allow a motorcycle to thread between two vehicles going the same direction unless an open lane makes the pass safe. Under 625 ILCS 5/11-703, a two-wheeled vehicle passing one vehicle on the left may not at the same time pass another on the right. The statute’s one exception is an unobstructed lane that lets the rider pass safely.

As of 2026, the Illinois Vehicle Code has no rule permitting lane splitting. A violation is evidence of carelessness the jury weighs, the same as the turning driver’s. Whether you were passing anything at all is decided on the evidence.

The driver got no ticket for turning in front of me. Does that decide it?

A ticket does not decide your case, and neither does the officer’s opinion on the crash report. The civil case is decided on evidence of what happened. If no ticket was written, your claim is unaffected; the jury still hears the evidence.

If the turning driver pleaded guilty to failing to yield, that plea can be used as an admission, a statement held against the person who made it. A conviction after the driver fought the ticket in court cannot be used as proof of what happened.

The written crash report is generally kept out of an Illinois injury trial, because it holds the officer’s conclusions and secondhand accounts. As a rule, the officer’s opinion of who was at fault is not evidence in the civil case. What the officer saw, measured and photographed at the scene can be, through the officer’s own testimony. The report still matters as a record of who was there, what they said and where things were. Call us before the report is back.

I felt fine at the scene and now my head hurts. What should I do?

Get seen. The CDC says some concussion symptoms appear right away and others may not appear for hours or days after the injury. Call 911 or go to an emergency department for any of the CDC’s danger signs in adults:

A headache that gets worse and does not go away.
Weakness, numbness, decreased coordination, convulsions or seizures.
Repeated vomiting.
Slurred speech or unusual behavior.
One pupil larger than the other.
Confusion, not recognizing people or places, restlessness or agitation.
Loss of consciousness, extreme drowsiness, or not being able to wake up.

Tell the provider you were on a motorcycle, how you landed, and every symptom, including the small ones. Our posts on motorcycle road rash and common motorcycle crash injuries cover the injuries riders see most.

What if the driver who hit me has no insurance, or not enough?

Your own motorcycle policy may pay. An Illinois motorcycle policy carries uninsured motorist coverage, called UM, by law under 215 ILCS 5/143a, at your bodily injury limits unless you rejected the higher amount in writing. When your UM limit is above the state minimum, the policy also carries underinsured motorist coverage, called UIM, at the same amount under 215 ILCS 5/143a-2.

UIM applies when the other driver’s liability limit is lower than your own UIM limit. The most your insurer pays is your UIM limit minus what you actually collected from the other driver’s insurer. The total from both sources can never exceed your actual damages (the losses the crash caused you). Check your declarations page (the summary page that lists your coverages) for the UM and UIM lines.

Tell your lawyer before accepting any settlement from the other driver’s insurer; your own policy has notice rules. If you were the passenger, the rider’s motorcycle policy may cover you under its UM and UIM lines, and your own auto policy may also apply. Whether you count as an insured depends on each policy’s words, so bring both policies to the consultation.

Is it too late? How long do I have?

You generally have two years to file. The clock depends on your age at the crash and on who you are suing:

Two years from the crash for an adult, under 735 ILCS 5/13-202.
Two years after turning 18 for a rider or passenger who was under 18, under 735 ILCS 5/13-211.
One year for claims against a city, county or other local public body under 745 ILCS 10/8-101, so ask early.

What is the next step?

Call. The consultation is free. The fee is a flat one-third contingency fee on personal injury cases, whether the case resolves before suit, after suit is filed, or at trial. No fee unless we win. Robert Parker personally handles every case the firm accepts, and we take motorcycle cases across Peoria, Tazewell, McLean, Knox and Woodford counties.

Get advice before you give a recorded statement to the adjuster handling the other driver’s claim, and before you answer that adjuster’s questions about what you were wearing. A recorded statement is the adjuster’s recorded interview with you about the crash and your injuries. You owe that adjuster no recorded statement. Requests from your own insurer are different: your policy has cooperation duties, so ask before you refuse and before you answer.

If a driver turned across your path, our Peoria motorcycle accident practice gathers the scene evidence, reads every policy that may apply, and handles the adjusters.

Call 309-673-0069 or use the contact page. If you are calling for a family member, you can make the first call. Bring what you have; partial information is welcome.

Frequently Asked Questions

Is the driver who turned left in front of a motorcycle automatically at fault in Illinois?

No. A jury decides each side’s share of fault in an Illinois motorcycle accident under 735 ILCS 5/2-1116. The turning driver must yield to an oncoming rider close enough to be an immediate hazard under 625 ILCS 5/11-902. The jury treats a violation as evidence of carelessness weighed with the rest of the crash evidence.

Can the insurance company use my missing helmet against me in Illinois?

Illinois has no helmet requirement. Illinois courts have therefore held that an adult rider’s missing helmet cannot be used to assign fault or to reduce damages in an injury case. The only gear the law requires is eye protection under 625 ILCS 5/11-1404.

Is lane splitting legal in Illinois?

As of 2026, no Illinois statute permits lane splitting. Under 625 ILCS 5/11-703, a two-wheeled vehicle passing one vehicle on the left may not at the same time pass another on the right, unless an open lane makes it safe. A violation is evidence of carelessness weighed as part of the rider’s share of fault.

Do I have to give the other driver’s insurance company a recorded statement after an Illinois motorcycle crash?

No. You owe the adjuster handling the other driver’s claim no recorded statement, and you should get advice before giving one. Requests from your own insurer, including on a UM or UIM claim, come with cooperation duties under your policy, so ask before you refuse or answer.

Who pays my medical bills while an Illinois motorcycle claim is open?

It depends on your health plan and your policies. Medical payments coverage on a vehicle policy (coverage under your own policy that pays medical bills) is optional, and whether that insurer can be repaid from the recovery depends on the policy language. Your health plan may have repayment rights of its own that need to be checked.

Motorcycle accident injuries are often severe. Our our Peoria personal injury practice understand the unique challenges riders face when pursuing a claim.
