How to File a Car Insurance Claim in Illinois: Complete Guide (2026)

Notify your own insurer promptly and ask which policy coverage can handle your injury or vehicle loss. If you are seeking payment from the other driver, also obtain that insurer’s liability claim number and written assessment. Keep those two routes separate: your policy’s coverage and deductible do not follow automatically from the other driver’s fault.

Under 735 ILCS 5/2-1116, a claimant whose contributory fault is more than 50% is barred from recovering damages in the negligence action. At 50% or less, any damages allowed are reduced by that percentage. A 50/50 finding therefore permits half of the proven damages; it does not guarantee an insurance payment.

With approximately 320,000 car accidents per year, Illinois drivers need to understand how the claims process works and what the state's unique rules mean for their recovery.

KEY TAKEAWAYS:

- Illinois is a fault state — the at-fault driver's insurance pays

Fault check: Exactly 50% contributory fault permits proportionately reduced damages; more than 50% bars negligence recovery. Preserve the evidence and ask for the insurer's written assessment.

- Notify police promptly when required; retain the case number

- Minimum insurance: 25/50/20

- Check actual UM/UIM bodily injury limits and claim conditions

- Statute of limitations: 2 years PI, 5 years PD (longest PD deadline among fault states on this site)

- Dram Shop Act allows claims against establishments that served alcohol to a drunk driver

How Illinois's Fault-Based System Works

In Illinois, the person who caused the accident is financially liable for all resulting damages. Illinois requires all drivers to carry minimum liability insurance of 25/50/20 (625 ILCS 5/7-601):

• $25,000 per person for bodily injury
• $50,000 per accident for bodily injury
• $20,000 for property damage

These minimums are moderate compared to other states. The property damage minimum ($20,000) is lower than states like Ohio ($25,000) or Texas ($25,000), which can be a concern when damage is significant.

The modified comparative fault rule (735 ILCS 5/2-1116)

• If you are 50% or less at fault, you can recover damages, reduced by your fault percentage
• If you are more than 50% at fault, you recover nothing

Notify Police and Obtain the Report

If no officer is present, promptly notify the local police, county sheriff, or Illinois State Police by the fastest available means when the crash involves injury, death, or property damage exceeding $1,500; the property threshold is $500 if a vehicle required to have liability insurance is uninsured. Section 11-407 also covers specified school-bus crashes. Ask the responding agency for its report number and how to obtain a copy. Do not wait ten days to give required immediate notice.

Required immediate police notice depends on injury, death, and the applicable property-damage threshold, including the lower threshold for an uninsured vehicle. If no officer responds, contact the appropriate police agency; do not rely on an old ten-day driver filing rule.

Step 2 — Gather Your Documentation

Thorough documentation is your strongest tool in any Illinois claim. Collect:

• Police report — request from the responding law enforcement agency
• Photos and video — all vehicle damage, the accident scene, road conditions, traffic signals, weather conditions, and visible injuries
• Medical records — emergency room, urgent care, primary care, specialists, physical therapy
• Medical bills — itemized bills from every provider
• Proof of lost income — pay stubs, employer letter, W-2s, or tax returns if self-employed
• Witness information — names, phone numbers, written or recorded statements
• Insurance information — policy details for all drivers involved
• Repair estimates — from at least two reputable body shops
• Dashcam footage — if available, from your vehicle or nearby vehicles

Step 3 — Notify Your Insurance Company

Contact your own insurer promptly to report the accident, even if you intend to file a claim against the other driver. Your policy likely requires timely notification. Provide basic factual information without speculating about fault.

Step 4 — Choose Your Claim Path

In Illinois's fault-based system, you have three options:

1. First-party claim (your insurer): File under your own collision coverage. You pay your deductible upfront. Your insurer handles the repairs and may pursue the at-fault driver's insurance through subrogation to recover costs and your deductible.

1. Third-party claim (at-fault driver's insurer): File directly against the at-fault driver's liability policy. No deductible, but the process typically takes longer and involves negotiation with the other company's adjuster.

1. Lawsuit: If insurance claims do not produce a fair result, file a lawsuit. The statute of limitations is 2 years for personal injury and 5 years for property damage in Illinois.

Step 5 — Work with the Insurance Adjuster

Once you file a claim, an adjuster will investigate the accident. They will:

• Review the police report and all submitted documentation
• Inspect vehicle damage (in person or via photos)
• Request a recorded statement from you
• Evaluate fault percentages for all drivers
• Calculate a settlement offer

Tips for working with the adjuster:

• Stick to facts. Do not speculate about what happened or admit fault.
• You are not legally required to give a recorded statement to the other driver's insurer. If you choose to, be concise and accurate.
• Review the offer against the documented losses, any fault reduction, coverage, and the release language. Request a written explanation for missing or reduced items. Get individual advice before releasing a claim involving unresolved injuries or a disputed deadline.
• Do not sign a blanket medical records release. Only authorize release of records related to accident injuries.
• Document every interaction: dates, times, names, and summaries of conversations.

Step 6 — Negotiate Your Settlement

Compare the offer against your documented damages:

• Medical expenses — all treatment to date and estimated future treatment
• Lost wages — income lost during recovery and any future earning capacity reduction
• Property damage — repair costs or fair market value if the vehicle is totaled
• Pain and suffering — no formula in Illinois law; typically calculated based on the severity and duration of your injuries
• Loss of normal life — Illinois recognizes this as a distinct category of damages

Submit a written counteroffer with specific documentation supporting each category if the initial offer is too low. Be prepared for multiple rounds of negotiation.

What to Do If Your Claim Is Denied

Claim denials in Illinois can happen for various reasons: disputed liability, insufficient documentation, policy exclusions, or failure to meet deadlines. If your claim is denied:

1. Request the denial in writing with specific reasons.
2. Review your policy to understand your coverage, limits, and exclusions.
3. Collect additional evidence that addresses the stated reason for denial.
4. File a formal appeal with the insurance company.
5. File a complaint with the Illinois Department of Insurance (DOI). The DOI investigates consumer complaints and can take action against insurers engaging in unfair practices.
6. Consult an Illinois car accident attorney. An attorney can evaluate whether the insurer is acting in bad faith and advise on next steps, including litigation.

The Dram Shop Act (235 ILCS 5/6-21)

Illinois's Dram Shop Act is one of the most important state-specific laws for car accident claims. If a drunk driver caused your accident, you may be able to pursue a claim against the bar, restaurant, or liquor store that served them alcohol. The Dram Shop Act creates a separate cause of action against the establishment, which provides an additional source of recovery beyond the driver's insurance.

This can be particularly valuable when the drunk driver has minimum coverage or is uninsured. Dram Shop claims have their own limits and procedures, so consulting an attorney is recommended.

Required UM/UIM Coverage

Check your policy’s uninsured motorist bodily injury limits. Illinois requires at least $25,000 per person and $50,000 per accident. Additional UM limits generally match bodily injury liability limits unless properly rejected in writing; UIM is required when UM exceeds the minimum. Coverage, exclusions, and claim conditions still matter. For vehicle damage, check collision or separate uninsured motorist property-damage coverage.

5-Year Property Damage Statute of Limitations

Illinois gives you 5 years to file a property damage lawsuit — the longest among all fault states covered on this site. This extended deadline provides more time to resolve property damage disputes. However, the personal injury deadline remains only 2 years, so time is still critical for injury claims.

Higher Reporting Threshold ($1,500)

Illinois no longer requires the old driver crash report under repealed Section 11-406. Required immediate police notice is separate. Contact the investigating agency for the report number, availability, and any factual correction process.

---

Settlement Ranges by Injury Severity

There is no verified settlement range here that can value an individual claim. Compare documented medical costs, lost income, vehicle losses, and any supported lasting effects with the actual coverage and offer. A diagnosis or collision type does not assign a payout.

These are general estimates. Actual settlements depend on fault allocation, insurance limits, medical documentation, and the strength of the evidence.

Can I sue a bar that served a drunk driver who hit me?

Potentially, yes. Under the Illinois Dram Shop Act (235 ILCS 5/6-21), you can file a claim against any establishment that sold or gave alcohol to a person who was intoxicated at the time. This creates a separate recovery source beyond the driver's insurance policy. Note that the Dram Shop Act has a shorter statute of limitations (1 year) than the general personal injury deadline (2 years).

What makes Illinois's property damage deadline unique?

Illinois has a 5-year statute of limitations for property damage claims, which is the longest among fault states covered on this site. By comparison, the personal injury deadline is only 2 years. This extended PD deadline gives you more time, but you should still pursue property damage claims as quickly as possible to preserve evidence and get your vehicle repaired.

How does the modified comparative fault rule compare to other states?

For an Illinois negligence claim, exactly 50% contributory fault allows proportionately reduced damages; more than 50% bars recovery. Ask for the evidence supporting a disputed allocation rather than relying on another state’s shorthand rule.

Common Mistakes Illinois Drivers Make After a Car Accident

Navigating the aftermath of a car accident in Illinois involves specific state rules and deadlines. Understanding common missteps can help drivers protect their potential for recovery, especially given Illinois's modified comparative fault system.

• Notify police promptly when required. If no officer is present, use the fastest available means. Obtain the case number and ask how to get the police report; do not wait for a ten-day personal IDOT filing deadline.
• Admitting Fault at the Scene — Illinois operates under a modified comparative fault rule. If a driver is found to be more than 50% at fault for an accident, they are barred from recovering any damages. Admitting fault, even partially, can significantly jeopardize a claim and be used by insurance adjusters to deny or reduce compensation.
• Missing the Personal Injury Statute of Limitations — In Illinois, there is generally a 2-year statute of limitations for filing a personal injury lawsuit. Waiting too long to pursue a claim can mean losing the legal right to seek compensation for injuries sustained in the accident, regardless of fault.
• Failing to Document Injuries Promptly — Even seemingly minor injuries can worsen over time. A delay in seeking medical attention and thoroughly documenting all injuries can make it more challenging to establish a direct link between the accident and the injuries, which is key for any personal injury claim under Illinois's fault system.
• Providing a Recorded Statement Without Preparation — Insurance adjusters may request a recorded statement shortly after an accident. While cooperation is often necessary, providing a statement without understanding its potential implications or reviewing the facts can lead to inconsistencies or statements that are later used to dispute a claim, particularly concerning fault in Illinois.
• Underestimating the Impact of Minimum Liability Coverage — Illinois requires minimum liability coverage of 25/50/20. If damages from an accident exceed these amounts, the at-fault driver's insurance may not fully cover all losses. Drivers who do not have sufficient Uninsured/Underinsured Motorist (UM/UIM) coverage on their own policy may find their recovery limited, highlighting the importance of understanding these thresholds.

What is Illinois's fault rule, and how does it affect my car insurance claim?

Illinois follows a modified comparative fault rule. This means that if you are found to be more than 50% responsible for an accident, you are generally barred from recovering any damages from the other driver's insurance. If you are 50% or less at fault, your recoverable damages will be reduced by your percentage of fault.

How long do I have to file a personal injury claim after a car accident in Illinois?

In Illinois, the statute of limitations for filing a personal injury lawsuit after a car accident is generally two years from the date of the accident. It is often advisable to initiate the claims process well before this deadline to allow sufficient time for investigation and negotiation.

Is Personal Injury Protection (PIP) coverage required in Illinois?

No, Illinois is not a no-fault state, and Personal Injury Protection (PIP) coverage is not required for drivers. As a traditional fault state, the at-fault driver's liability insurance typically covers the damages, including medical expenses, for the injured parties.

When Professional Help Tends to Make Sense

Most minor accidents in Illinois are resolved between the drivers and their insurance companies without ever involving an attorney. Many accident victims, however, consider consulting an attorney when one or more of the following applies to their situation:

• A fatality occurred, or a wrongful-death claim may be involved
• Medical bills are already in the tens of thousands of dollars, or still growing
• There is a permanent injury, visible scar, or any sign of traumatic brain injury (TBI)
• The insurance company's first settlement offer feels far below your actual costs
• The insurance company is arguing that your injuries are pre-existing, or trying to shift primary fault onto you despite the evidence
• Multiple vehicles or multiple parties are involved and liability is unclear
• Fault is disputed — especially relevant given Illinois's modified comparative fault rule (any plaintiff more than 50% at fault recovers nothing)
• The Illinois statute of limitations for personal injury (2 years from the accident) is within six months
• A government vehicle, commercial truck, or rideshare driver is involved
• The other driver was uninsured, underinsured, or fled the scene (hit-and-run)

If none of these apply to your situation, you may be able to settle directly with the insurance company. The other guides on this site walk through that process step by step.
