Illinois car accident law rests on a few long-standing rules: a two-year filing deadline for most injury claims, fault-based liability, a 50% fault bar, and mandatory minimum insurance. This guide explains how each one works in 2026, with the statutes behind them, so you know where you stand after a crash in Chicago, IL or anywhere else in the state.

How Fault Works in Illinois
Fault Determines Liability
Illinois is a fault-based state, meaning the driver whose negligence caused the crash is generally responsible for the losses. Liability is based on:
- Duty of care owed by all drivers
- Breach of that duty (e.g., speeding, distracted driving)
- Causation between breach and crash
- Resulting damages (medical costs, lost wages, pain, etc.)
Modified Comparative Negligence
Illinois uses modified comparative negligence (735 ILCS 5/2-1116). If you are 50% or less at fault, you can recover damages, but your award is reduced by your percentage of fault. If you are more than 50% responsible, you are barred from recovery.
Illinois Insurance Requirements
Minimum Liability Coverage
Illinois requires every registered vehicle to carry liability insurance of at least $25,000 bodily injury per person, $50,000 bodily injury per accident, and $20,000 property damage (25/50/20). Serious injuries can easily cost more than these limits, so a driver who carries only the minimum may not have enough coverage to pay your full losses.
Uninsured and Underinsured Motorist Coverage
Auto liability policies in Illinois must include uninsured motorist coverage unless you reject it in writing, and underinsured motorist coverage is written the same way. These coverages let you recover from your own insurer when the at-fault driver has no insurance or too little. For how the numbers work, see our guide on how much you can get from an underinsured motorist claim.
Illinois Filing Deadlines
The clock starts on the date of the crash, and the deadline depends on who you are suing and what you are claiming:
- 2 years for most personal injury claims
- 5 years for property damage claims
- 2 years from the date of death for wrongful death claims
- 1 year to file suit against a local government entity
- For injured minors, 2 years after their 18th birthday
Preparing a claim takes time. It involves obtaining medical records, interviewing witnesses, collecting police reports, securing crash scene evidence, and sending demand letters. Missing the deadline can mean permanently losing the right to bring a lawsuit, so start early.
Pedestrians and Cyclists
Drivers must stop and yield to a pedestrian crossing within a crosswalk on the driver’s half of the roadway when no traffic signal controls the crossing (625 ILCS 5/11-1002(a)). A driver who fails to yield can be found negligent for the resulting injuries. Chicago’s dense intersections, buses, and heavy foot traffic make these crashes common, and the same fault rules apply to injured cyclists.
Rideshare Crashes
Crashes involving Uber and Lyft can involve several insurance policies, and which one applies often depends on whether the driver was logged into the app or carrying a passenger. Rideshare volumes are high in Chicago, so it is worth telling your attorney early if a rideshare vehicle was involved.
Electronic Evidence and Crash Data
Digital evidence can help reconstruct how a crash happened and reduce disputes over fault. It includes:
- Vehicle telematics data (brake application, speed, airbags, etc.)
- Smartphone GPS, call, and messaging records
- Dashcam or city surveillance footage
Much of this evidence is overwritten quickly, so ask an attorney to send preservation requests as soon as possible.
What to Do After a Car Accident in Illinois
Here is a practical process to follow if you are involved in a collision:
1. Check for Injuries and Call 911
Your first priority after any crash is safety. Call 911 immediately if anyone is injured, even if injuries appear minor at first. Some conditions, such as concussions or internal injuries, may not show symptoms right away. Prompt medical care protects both your health and your legal claim. Emergency records also create early documentation linking injuries to the accident.
2. Report the Crash if Required
Have the police respond to the scene, especially if anyone is hurt or the vehicles are damaged. A police report gives insurers and courts an official record of what happened. Ask the responding officer how to get a copy of the report for your records.
3. Gather Evidence at the Scene
If it is safe to do so, document the accident scene thoroughly. Take photos of vehicle damage, license plates, road markings, traffic signals, and visible injuries. Note weather conditions and lighting, as these factors often affect fault analysis. This evidence can disappear quickly once vehicles are moved or roads are cleared. Strong visual proof can significantly strengthen your claim.
4. Exchange Information
Illinois law requires drivers involved in a crash to exchange identifying and insurance information. Collect names, phone numbers, driver’s license numbers, insurance carriers, and policy numbers. Avoid discussing fault or making statements about blame at the scene. Keep conversations factual and limited. Accurate information prevents delays when filing insurance claims.
5. Notify Your Insurance Company
Most insurance policies require prompt notice of any accident, regardless of fault. Provide basic facts such as time, location, and vehicles involved. Avoid giving recorded statements or accepting early settlement offers without legal advice. Insurers often look for ways to limit payouts. Timely notice protects your right to coverage.
6. Preserve Digital Evidence
If your phone, vehicle, or dashcam recorded any data during the crash, preserve it immediately. Do not delete photos, videos, messages, or GPS records. Digital evidence can help show speed, braking, and driver behavior. Tell your attorney early so it can be secured before it is overwritten.
Why You Need an Attorney
An experienced car accident lawyer can:
- Explain how Illinois law applies to your situation
- Make sure you meet the filing deadline that applies to your claim
- Determine whether coverage such as uninsured or underinsured motorist insurance is available to you
- Evaluate insurance policy language to secure the coverage you are entitled to
- Manage negotiations with insurers who often resist paying full claims
Chicago Specific Considerations
Chicago has distinct legal and traffic patterns that affect car crash claims:
- Heavy congestion increases multi-vehicle crash risk
- Frequent pedestrian and cyclist interactions
- Complex intersections and one-way streets
- Public transportation vehicles involved in accident claims
- High medical and repair costs
These factors make having dedicated local counsel, familiar with Chicago courts and judges, particularly beneficial.
Common Types of Compensation in Illinois Car Accident Claims
Victims in Illinois may recover:
Medical Expenses
Medical expenses include all healthcare costs related to injuries caused by the accident. This covers emergency room visits, hospital stays, surgeries, diagnostic tests, medications, and physical therapy. Future medical expenses may also be included if ongoing treatment, rehabilitation, or long-term care is required. Illinois law allows recovery for both billed amounts and reasonably expected future costs. Medical records and expert opinions are often used to calculate these damages accurately.
Lost Wages and Earning Capacity
Lost wages compensate victims for income missed while recovering from accident-related injuries. This includes salary, hourly wages, overtime, bonuses, and used sick or vacation time. Loss of earning capacity applies when injuries reduce a person’s ability to work or force a career change. Even if a victim returns to work, reduced hours or lower pay may qualify. Documentation such as pay stubs, tax records, and employer statements supports these claims.
Property Damage
Property damage compensation covers repair or replacement of vehicles damaged in the crash. This may also include personal property inside the vehicle, such as phones, laptops, or child safety seats. Illinois allows recovery of fair market value if a vehicle is totaled. Towing, storage, and rental car expenses may also be reimbursed. Insurance estimates and repair invoices are commonly used to prove these losses.
Pain and Suffering
Pain and suffering address the physical discomfort and limitations caused by accident injuries. This includes ongoing pain, reduced mobility, and difficulty performing everyday activities. Unlike medical bills, these damages do not have a fixed dollar amount. Courts and insurers consider injury severity, recovery time, and long-term effects. Medical documentation and personal testimony often support these claims.
Mental Anguish
Mental anguish refers to emotional and psychological harm caused by the accident. This may include anxiety, depression, sleep disturbances, fear of driving, or post-traumatic stress symptoms. Illinois law recognizes that emotional injuries can be just as disruptive as physical ones. Mental health treatment records and professional evaluations help establish these damages. The impact on daily life is a key factor in valuation.
Loss of Consortium
Loss of consortium applies when an accident affects a victim’s relationship with their spouse. This includes loss of companionship, affection, emotional support, and marital intimacy. These damages are typically claimed by the uninjured spouse. Illinois courts consider how injuries change household roles and personal relationships. Medical evidence and testimony from both spouses are often used to support this claim.
Out-of-Pocket Costs
Out-of-pocket expenses cover costs paid directly by the victim that are not always included elsewhere. Examples include transportation to medical appointments, home modifications, medical supplies, and childcare during recovery. These expenses may seem minor individually but can add up quickly. Illinois law allows reimbursement when costs are reasonable and accident-related. Receipts and records are important for proving these losses.
Frequently Asked Questions (FAQs)
What is the deadline to file a car accident lawsuit in Illinois?
In most cases, you have two years from the date of the crash to file an injury lawsuit (735 ILCS 5/13-202) and five years for property damage (735 ILCS 5/13-205). Wrongful death claims also have a two-year deadline, counted from the date of death. Claims against a city, county, or other local government must be filed within one year (745 ILCS 10/8-101). Missing the deadline usually means losing the right to sue, so speak with a lawyer early.
What are the minimum insurance requirements in Illinois?
Illinois requires liability coverage of at least $25,000 per person and $50,000 per accident for bodily injury, and $20,000 for property damage (625 ILCS 5/7-203). Auto liability policies must also include uninsured motorist coverage unless you reject it in writing (215 ILCS 5/143a). Many drivers carry only the minimum, which is why your own uninsured and underinsured motorist coverage matters.
Does Illinois have no-fault insurance?
No. Illinois is an at-fault state, so the driver who caused the crash is responsible for the losses, and you generally recover from that driver’s insurance company. You can also turn to your own coverage, such as medical payments or uninsured motorist coverage, if you carry it.
Can I still recover if I was partly at fault?
Yes, as long as you were 50% or less at fault. Your compensation is reduced by your percentage of fault, and if you are found more than 50% at fault you cannot recover (735 ILCS 5/2-1116).
What protections do pedestrians have when a driver hits them?
A driver must stop and yield to a pedestrian crossing within a crosswalk on the driver’s half of the roadway when no traffic signal controls the crossing (625 ILCS 5/11-1002(a)). A driver who fails to yield can be found negligent, and an injured pedestrian can still recover compensation if they were 50% or less at fault.
Should I talk to my insurance company without a lawyer?
It is important to notify your insurer promptly, but you should not provide detailed recorded statements or accept early settlement offers without legal advice. Insurers often seek to minimize payouts, and a lawyer can protect your rights and work to secure fair compensation.
