What If the Insurance Company Denies Your Car Accident Claim in Illinois?

You were injured in a car accident that you believe another driver caused.

Your vehicle is damaged. You are experiencing pain, attending medical appointments, and trying to recover while managing your everyday responsibilities.

You report the accident to the insurance company, submit photographs, provide medical records, and cooperate with the claims investigation.

Weeks later, you receive a letter informing you that your claim has been denied.

The insurance company may argue that its insured was not responsible for the accident, that your injuries were unrelated to the collision, or that the available evidence does not support your claim.

Now you are facing medical expenses, lost wages, and uncertainty about your financial future.

You may wonder:

Can an insurance company simply deny your car accident claim? And what can you do if you disagree with its decision?

The answer depends on the circumstances, but an insurance company’s denial does not necessarily mean you have no right to compensation.

In Illinois, individuals injured by another person’s negligence may have legal options even when an insurance company refuses to pay a claim.

At Pinkston Law Group, P.C., Attorney Danielle A. Pinkston represents individuals pursuing compensation for injuries caused by motor vehicle accidents.

Understanding why insurance companies deny claims—and how to respond—can help protect your legal rights.

1. Can an Insurance Company Deny a Car Accident Claim in Illinois?

Yes. Insurance companies may deny claims when they believe the available evidence, policy language, or applicable law does not support payment.

However, a denial is not automatically correct.

Insurance companies investigate claims to determine whether coverage exists, whether their insured may be legally responsible, and whether the claimed damages are supported.

A denial may involve a legitimate coverage dispute, insufficient documentation, conflicting evidence, or disagreement about liability.

In other circumstances, an insurer’s decision may be based on an incomplete investigation or an unreasonable interpretation of the available evidence.

The important distinction is that an insurance company’s determination is not necessarily the final legal determination of your rights.

Depending on the circumstances, you may be able to challenge the denial, provide additional evidence, pursue a claim against the responsible driver, or seek other available remedies.

2. Why Do Insurance Companies Deny Car Accident Claims?

Insurance companies deny car accident claims for several reasons.

Understanding the stated reason for denial is an important first step toward determining how to respond.

The Insurance Company Disputes Fault

An insurer may argue that its insured did not cause the collision.

For example, after an intersection accident, both drivers may claim they had the right of way.

The insurance company may accept its insured’s version of events and deny your claim.

However, other evidence—including traffic-camera footage, witness statements, vehicle damage, and accident reconstruction—may support a different conclusion.

The Insurance Company Claims You Were Responsible

An insurer may argue that you caused the accident or contributed substantially to it.

Illinois follows a modified comparative negligence system.

Under 735 ILCS 5/2-1116, a plaintiff whose contributory fault does not exceed 50% may generally recover damages in a negligence action governed by that statute, although recovery is reduced by the plaintiff’s percentage of fault.

An insurer’s assertion that you were partially responsible does not automatically eliminate your potential claim.

The Insurance Company Disputes Your Injuries

An insurer may acknowledge that an accident occurred but deny that it caused the injuries you are claiming.

For example, the insurer may argue that your neck, back, or shoulder symptoms resulted from a preexisting condition rather than the collision.

Medical records, diagnostic testing, treating physician opinions, and other evidence may help establish whether the accident caused or aggravated your injuries.

The Insurance Company Claims Your Medical Treatment Was Unnecessary

An insurer may challenge the necessity, reasonableness, or relationship of medical treatment to the accident.

Disputes may involve physical therapy, injections, diagnostic imaging, surgery, or other treatment.

Medical documentation and appropriate expert testimony may help address these disagreements.

The Insurance Company Identifies a Coverage Problem

Some denials involve insurance coverage rather than negligence.

For example, the insurer may claim:

• The policy was not in effect on the accident date.
• The driver was excluded from coverage.
• The vehicle was not covered under the policy.
• The claim falls within a policy exclusion.
• The claimant failed to satisfy a policy requirement.

The validity of a coverage denial depends on the policy language, applicable Illinois law, and the circumstances.

The Insurance Company Claims There Is Insufficient Evidence

An insurer may conclude that the available evidence does not establish its insured’s liability or the amount of damages claimed.

A lack of witnesses, incomplete medical documentation, or conflicting accounts may contribute to this decision.

However, additional investigation may uncover evidence that changes the analysis.

3. What Should You Do Immediately After Your Car Accident Claim Is Denied?

Do not assume that the denial means your case is over.

Instead, begin by understanding the insurer’s stated reasons and preserving the evidence supporting your claim.

Step 1: Request the Denial in Writing

If you receive a verbal denial, request written confirmation explaining the insurer’s position.

Review the denial carefully.

Determine whether the insurer is disputing:

• Liability for the accident.
• Insurance coverage.
• The relationship between the accident and your injuries.
• The necessity or amount of medical treatment.
• The amount of compensation requested.
• Compliance with policy conditions.

A written explanation can help identify the issues requiring further investigation.

Step 2: Review the Available Evidence

Gather and preserve relevant documentation, including:

• Police reports.
• Photographs of the accident scene.
• Vehicle damage photographs.
• Witness contact information.
• Surveillance or dashcam recordings.
• Medical records and bills.
• Employment records documenting lost income.
• Correspondence with insurance adjusters.
• The denial letter.

Evidence may help challenge an inaccurate liability assessment or demonstrate that the insurer overlooked important information.

Step 3: Identify the Insurance Policy Involved

Determine whether the denial came from:

The at-fault driver’s liability insurer, which generally evaluates whether its insured is legally responsible for your damages; or

Your own insurance company, which may owe contractual benefits under uninsured motorist, underinsured motorist, medical payments, collision, or other applicable coverage.

This distinction matters because your rights and available remedies may differ.

Step 4: Consult a Personal Injury Attorney

An attorney can evaluate the insurer’s stated reasons, investigate the collision, review relevant policies, and explain your potential legal options.

Prompt consultation is particularly important when the statute of limitations is approaching.

4. Can You Challenge an Insurance Company’s Determination of Fault?

Yes.

An insurance company’s assessment of fault is not automatically binding in a civil lawsuit.

For example, suppose an insurance adjuster determines that you were primarily responsible for an intersection collision.

However, a nearby business has surveillance footage showing that the other driver entered the intersection against a red light.

That evidence may support a different liability determination.

Depending on the circumstances, an attorney may investigate:

• Traffic signals and right-of-way rules.
• Vehicle positioning and damage.
• Skid marks and roadway conditions.
• Witness statements.
• Cellphone use or distracted driving.
• Available video recordings.
• Relevant accident reconstruction evidence.

If the case proceeds to trial, the finder of fact may determine negligence and comparative fault under the applicable law.

You do not have to accept an insurance company’s fault assessment simply because an adjuster reached that conclusion.

5. What If the Insurance Company Says You Were Partially at Fault?

Being partially responsible for an accident does not necessarily prevent you from recovering compensation.

Under Illinois’ modified comparative negligence law, an injured plaintiff may generally recover damages if their contributory fault does not exceed 50%, assuming the remaining legal requirements are satisfied.

For example, suppose your total legally established damages are $100,000.

If you are found 25% responsible for the accident, your recovery would generally be reduced by 25%, resulting in $75,000.

If your fault exceeds 50%, recovery is generally barred under the applicable statute.

However, determining fault can be complicated.

Insurance companies may argue that you were speeding, failed to keep a proper lookout, or otherwise contributed to the collision.

The relevant question is whether the evidence supports those allegations and whether the conduct legally contributed to your injuries.

6. What If the Insurance Company Says Your Injuries Were Preexisting?

An insurance company may argue that your injuries existed before the accident.

However, a preexisting condition does not automatically prevent compensation.

Illinois law may permit recovery when another person’s negligence aggravates an existing injury or condition.

For example, suppose you previously experienced occasional lower-back discomfort.

After a rear-end collision, your symptoms become significantly worse, requiring additional treatment and limiting your ability to work.

Medical evidence may help establish whether the collision aggravated your prior condition.

Important documentation may include:

• Medical records before the accident.
• Emergency department records.
• Diagnostic imaging.
• Physical therapy records.
• Treating physician evaluations.
• Medical opinions addressing causation.
• Evidence of changes in your physical functioning.

An injured person generally must prove that the defendant’s negligence caused or aggravated the claimed injuries.

7. What If the At-Fault Driver’s Insurance Company Refuses to Pay?

When another driver’s liability insurer denies your claim, you may still have a negligence claim against the responsible driver.

This is an important distinction.

In an ordinary third-party car accident claim, the lawsuit is generally brought against the allegedly negligent driver—not directly against that driver’s liability insurance company.

The insurer may provide a defense and pay a covered judgment or settlement according to the policy and applicable law.

However, its denial of your claim does not necessarily eliminate the driver’s potential legal liability.

If settlement negotiations fail, filing a lawsuit against the appropriate defendant may be necessary to pursue compensation.

8. Can You Sue Your Own Insurance Company for Denying a Claim?

Potentially, depending on the circumstances.

Claims involving your own insurer are different from claims involving another driver’s liability insurer.

For example, you may have purchased uninsured motorist or underinsured motorist coverage.

If your insurer denies benefits you believe are owed, the dispute may involve policy interpretation, contractual obligations, arbitration, or other legal remedies.

Illinois law also provides potential remedies for certain unreasonable and vexatious insurance claim handling under 215 ILCS 5/155.

However, Section 155 does not automatically apply whenever an insurance company denies a claim.

Whether a remedy is available depends on the nature of the insurance relationship, the policy, the insurer’s conduct, and the governing law.

A legitimate dispute over coverage or the amount owed does not necessarily establish unreasonable or vexatious conduct.

9. What If the Insurance Company Offers Less Than Your Claim Is Worth?

Sometimes an insurance company does not deny a claim entirely.

Instead, it offers an amount that the injured person believes is insufficient.

For example, an insurer may offer enough to cover a portion of medical expenses but little compensation for lost wages, physical pain, or limitations on daily activities.

A settlement evaluation may consider:

Medical expenses: Reasonable treatment expenses attributable to the accident.

Lost wages: Income lost because of accident-related injuries.

Future medical treatment: Reasonably established future care needs.

Pain and suffering: Physical pain caused by the injuries.

Loss of normal life: Proven limitations on ordinary activities.

Other damages: Additional legally recoverable losses supported by the evidence.

An attorney can evaluate the available evidence and help determine whether an offer reasonably reflects the claim’s potential value.

10. Does an Insurance Claim Denial Mean You Must Go to Trial?

No.

A denied claim does not automatically require a trial.

Depending on the circumstances, the dispute may be resolved through additional investigation, negotiations, applicable insurance dispute procedures, mediation, or litigation.

Even when a lawsuit is filed, the parties may continue discussing settlement.

However, some cases require judicial resolution when the parties cannot agree about liability, damages, or other disputed issues.

A trial may ultimately be necessary if the case cannot otherwise be resolved.

11. What Evidence Can Help Overturn an Insurance Claim Denial?

The most useful evidence depends on the insurer’s stated reason for denying the claim.

If the insurer disputes fault, relevant evidence may include:

• Traffic-camera recordings.
• Witness statements.
• Vehicle damage photographs.
• Accident reconstruction.
• Police reports.
• Roadway measurements.

If the insurer disputes injuries, relevant evidence may include:

• Medical records.
• Diagnostic testing.
• Treating physician opinions.
• Medical billing records.
• Physical therapy documentation.
• Evidence of changes in physical functioning.

If the insurer disputes insurance coverage, relevant documents may include:

• The complete insurance policy.
• Policy declarations.
• Relevant endorsements.
• Premium payment records.
• Claim correspondence.
• Applicable insurance notices.

A successful challenge requires addressing the actual basis for the denial rather than simply disagreeing with the insurer’s conclusion.

12. How Long Do You Have to Sue After an Insurance Company Denies Your Claim?

This is one of the most important questions injured individuals should ask.

In Illinois, most ordinary personal injury lawsuits are subject to a general two-year statute of limitations under 735 ILCS 5/13-202.

For most car accident injury claims, that period generally begins when the cause of action accrues, ordinarily on the accident date.

Receiving an insurance denial does not ordinarily restart the two-year deadline.

For example, suppose you were injured in a collision on January 15, 2026.

Under the ordinary rule, the deadline for filing a personal injury lawsuit would generally fall on January 15, 2028.

If the insurance company denies your claim in December 2027, you should not assume that you have another two years to file suit.

Special deadlines may apply to certain governmental defendants.

Claims under your own insurance policy may also involve contractual notice requirements, arbitration provisions, or other applicable deadlines.

Prompt legal advice is essential.

13. What If the Insurance Company Delays Your Claim Instead of Denying It?

An insurance company may continue requesting documents, reviewing medical records, or investigating liability without issuing a final decision.

Some investigations take time for legitimate reasons.

However, prolonged claims handling can create serious problems when the lawsuit deadline is approaching.

An ongoing insurance investigation generally does not suspend the statute of limitations for a negligence lawsuit.

If you are approaching the applicable filing deadline, you should consult an attorney rather than assume that continued negotiations will protect your claim.

14. Can You File a Complaint Against an Insurance Company in Illinois?

Depending on the circumstances, consumers may submit complaints about insurance practices to the Illinois Department of Insurance.

The Department may review complaints involving matters within its regulatory authority.

However, a regulatory complaint is not a substitute for filing a lawsuit or pursuing contractual remedies.

The Department generally does not serve as your personal injury attorney or determine every disputed question of negligence and damages.

Filing an insurance complaint does not ordinarily stop the statute of limitations from running.

If you believe your claim was improperly denied, legal advice can help you identify the appropriate next steps.

15. What Mistakes Should You Avoid After an Insurance Claim Denial?

Certain decisions may make an already difficult situation more complicated.

Mistake 1: Assuming the Denial Is Final

An insurance company’s decision may be challenged through appropriate legal or contractual procedures.

Mistake 2: Missing the Filing Deadline

Waiting too long may jeopardize your ability to pursue compensation.

Mistake 3: Failing to Preserve Evidence

Photographs, surveillance recordings, and witness information may become unavailable over time.

Mistake 4: Stopping Necessary Medical Treatment Solely Because the Claim Was Denied

Continue making medical decisions with your healthcare providers. Discuss financial concerns and available payment options with the appropriate professionals.

Mistake 5: Accepting an Inadequate Settlement Without Understanding the Release

A signed settlement agreement may release legal claims, including claims you later wish to pursue.

Mistake 6: Giving Inaccurate or Speculative Statements

Provide truthful information and avoid guessing about disputed facts.

Mistake 7: Failing to Identify All Available Insurance Coverage

Depending on the circumstances, additional policies or coverages may be relevant.

16. Frequently Asked Questions About Denied Car Accident Claims in Illinois

Can an insurance company deny my claim even if the other driver received a traffic ticket?

Yes. A traffic citation may be relevant evidence, but it does not automatically establish civil liability.

Can I sue if the at-fault driver’s insurance company denies my claim?

Potentially. You may have a negligence claim against the allegedly responsible driver, subject to the applicable legal requirements and deadlines.

Can I recover compensation if the insurer says I was partially responsible?

Possibly. Illinois’ modified comparative negligence law generally allows recovery when the plaintiff’s contributory fault does not exceed 50%, subject to the other requirements for recovery.

Can an insurance company deny my claim because I had a preexisting injury?

An insurer may dispute causation, but a preexisting condition does not automatically prevent recovery for an injury or aggravation caused by the accident.

Should I accept a settlement after my claim is denied?

Before accepting a settlement, evaluate the evidence, the terms of the proposed release, and whether the amount reasonably accounts for your legally recoverable damages.

Does filing an appeal with the insurance company extend my lawsuit deadline?

Generally, an internal review or reconsideration request does not automatically extend the deadline for filing a negligence lawsuit.
