How to File a Car Insurance Claim in Illinois

Illinois is a traditional fault state, meaning the driver who caused the accident is responsible for paying damages. When you are involved in a car accident in Illinois, you pursue compensation through the at-fault driver’s liability insurance or through your own policy. Illinois does not have a no-fault or PIP system, so there is no automatic first-party medical coverage regardless of fault.

What makes Illinois distinctive is its 2023 change to the comparative fault bar. Illinois shifted from a 51% bar to a stricter 50% bar, meaning that if you are found to be exactly 50% at fault, you now recover nothing. The state also has a higher-than-average DMV reporting threshold ($1,500), one of the longest property damage statutes of limitations (5 years), and the Dram Shop Act, which can open additional recovery options when alcohol is involved.

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

– 50% fault bar (changed from 51% in 2023) — at 50%+ fault, you recover nothing

– Report to IDOT within 10 days if $1,500+ damage or injuries

– Minimum insurance: 25/50/20

– UM/UIM coverage is required unless rejected in writing

– 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 50% Comparative Fault Bar (735 ILCS 5/2-1116)

Illinois’s comparative fault rule changed in 2023 under Public Act 102-0489. The state moved from a modified 51% bar to a stricter modified 50% bar. Here is what this means:

If you are 49% or less at fault, you can recover damages, reduced by your fault percentage
If you are 50% or more at fault, you recover nothing

This is a meaningful change from the old rule. Under the previous 51% bar, a plaintiff who was exactly 50% at fault could still recover (they would receive 50% of their damages). Under the current 50% bar, that same plaintiff recovers nothing.

Your Fault %	Damages Claimed	Recovery Under Old 51% Bar	Recovery Under Current 50% Bar
30%	$100,000	$70,000	$70,000
49%	$100,000	$51,000	$51,000
50%	$100,000	$50,000	$0
51%	$100,000	$0	$0

The practical effect: insurance adjusters now have even more incentive to push your fault percentage to exactly 50%, which is enough to eliminate your recovery entirely.

Step-by-Step: Filing Your Illinois Insurance Claim

Step 1 — File a Crash Report with IDOT (10 Days)

If the accident caused $1,500 or more in property damage or any injury or death, you must file a crash report with the Illinois Department of Transportation (IDOT) within 10 days.

Illinois’s $1,500 reporting threshold is higher than most states (Ohio is $1,000, Florida and Georgia are $500). This means some moderate-damage accidents in Illinois do not require a state report. However, you should still always get a police report regardless of the dollar amount, as it is essential evidence for your insurance claim.

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:

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.

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.

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.
Do not accept the first settlement offer. It is almost always below the fair value of your claim.
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:

Request the denial in writing with specific reasons.
Review your policy to understand your coverage, limits, and exclusions.
Collect additional evidence that addresses the stated reason for denial.
File a formal appeal with the insurance company.
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.
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.

Illinois-Specific Features That Affect Your Claim

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

Illinois is one of the states that requires uninsured/underinsured motorist (UM/UIM) coverage matching your liability limits, unless you specifically reject it in writing (625 ILCS 5/7-601). This means most Illinois drivers have UM/UIM coverage, whether or not they realize it.

UM/UIM coverage is critical when the at-fault driver has no insurance or insufficient coverage to pay your damages. Check your policy to confirm your UM/UIM limits and whether you signed a waiver.

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’s $1,500 reporting threshold is higher than most states. While this means fewer minor accidents require a formal IDOT report, it does not change the importance of documenting every accident. A police report is still recommended for any accident, regardless of the dollar amount, because it creates an official record that supports your insurance claim.

Settlement Ranges by Injury Severity

Injury Severity	Typical Settlement Range	Notes
Minor soft tissue (whiplash, strains)	$5,000 – $20,000	Resolves within weeks to months
Moderate (herniated disc, fractures)	$20,000 – $100,000	May require surgery or extended treatment
Severe (TBI, spinal cord, multiple fractures)	$100,000 – $500,000+	Long-term or permanent impact
Catastrophic (paralysis, amputation)	$500,000 – $2,000,000+	Lifetime care costs
Wrongful death	$500,000 – $5,000,000+	Depends on decedent’s age, income, dependents
Dram Shop claims (additional)	$50,000 – $1,000,000+	Separate from driver’s insurance

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

Key Deadlines Table

Deadline	Timeframe	Details
IDOT crash report	10 days	Required if $1,500+ damage or injuries
Notify your insurer	ASAP	Most policies require prompt notice
Personal injury lawsuit	2 years	735 ILCS 5/13-202
Property damage lawsuit	5 years	735 ILCS 5/13-205
Wrongful death lawsuit	2 years	740 ILCS 180/2
Dram Shop claim	1 year	235 ILCS 5/6-21 (shorter than PI SOL)

Frequently Asked Questions

How does the 50% fault bar affect my claim?

Under the current rule (effective January 1, 2023), if you are assigned exactly 50% or more fault for the accident, you recover nothing. Before 2023, Illinois used a 51% bar, which meant a 50/50 fault split still allowed partial recovery. The change makes fault determination even more critical and gives insurance adjusters an additional tool to deny claims.

What is the reporting threshold in Illinois?

The threshold is $1,500 — higher than most states. Accidents causing less than $1,500 in damage (and no injuries) do not legally require an IDOT report. However, you should still file a police report for any accident, as it creates important evidence for your claim.

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).

Is UM/UIM coverage required in Illinois?

Yes. Illinois law requires insurers to offer UM/UIM coverage matching your liability limits. This coverage is included in your policy unless you specifically rejected it in writing. If you were never given the option to reject it, the coverage applies by default. Check your policy declarations page to confirm.

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 50% bar compare to other states?

Illinois’s 50% bar is stricter than Ohio and Pennsylvania (both use a 51% bar, where exactly 50% fault still allows recovery). It matches Georgia’s 50% bar. North Carolina is the strictest of all with pure contributory negligence (even 1% fault bars recovery entirely).

What if the at-fault driver is uninsured?

If the at-fault driver has no insurance, your options include: filing under your own UM coverage (which Illinois requires unless you opted out), suing the driver personally, or using your collision coverage for vehicle repairs (you pay the deductible). UM coverage is typically the most practical route for uninsured driver accidents.

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.

Delaying the Official Crash Report — Illinois law generally requires a crash report to be filed with the Illinois Department of Transportation (IDOT) within 10 days if the accident results in more than ,500 in property damage or any injuries. Failing to meet this deadline can complicate the official record of the incident and may impact subsequent insurance claims.
Admitting Fault at the Scene — Illinois operates under a 50% bar modified comparative fault rule. If a driver is found to be 50% or more 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.

Frequently Asked Questions About the Insurance Claims Process in Illinois

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

Illinois follows a 50% bar modified comparative fault rule. This means that if you are found to be 50% or more responsible for an accident, you are generally barred from recovering any damages from the other driver’s insurance. If you are less than 50% 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 do I need to report a car accident to the Illinois Department of Transportation (IDOT)?

You generally need to report a car accident to the Illinois Department of Transportation (IDOT) within 10 days if the crash results in more than ,500 in property damage or if anyone involved in the accident sustains injuries. This reporting requirement helps ensure an official record of the incident.

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 50% bar modified comparative fault rule (any plaintiff 50% or more 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.
