How Long Do You Have to File a Car Accident Lawsuit in Illinois?

Imagine being injured in a car accident in Chicago.

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

Meanwhile, the insurance company tells you that your claim is still under review.

Weeks turn into months.

Perhaps the adjuster requests additional medical records, asks you to provide another statement, or tells you that settlement negotiations are progressing.

You assume that because the insurance company is communicating with you, there is no reason to worry about filing a lawsuit.

But what happens if the legal deadline passes while you are waiting for the insurance company to make an acceptable offer?

You could lose your ability to pursue compensation through the courts—even if you have a legitimate personal injury claim.

In Illinois, strict legal deadlines determine how long injured individuals generally have to file car accident lawsuits.

These deadlines are known as statutes of limitations.

Understanding them is essential because waiting too long can prevent you from recovering compensation for medical expenses, lost wages, pain and suffering, and other damages.

At Pinkston Law Group, P.C., Attorney Danielle A. Pinkston helps individuals injured in motor vehicle accidents understand their legal rights and evaluate their options for pursuing compensation.

Here is what you should know about the deadlines for filing a car accident lawsuit in Illinois.

1. What Is the Statute of Limitations for a Car Accident Lawsuit in Illinois?

In most Illinois car accident cases involving personal injuries, you generally have two years from the date of the accident to file a lawsuit.

The applicable statute is 735 ILCS 5/13-202, which establishes a general two-year limitations period for actions seeking damages for injuries to the person.

For example, suppose you were injured in a car accident on November 15, 2026.

Under the ordinary two-year rule, the filing deadline would generally fall on November 15, 2028, subject to applicable rules and exceptions.

However, not every accident claim follows the same deadline.

The applicable limitations period may depend on factors such as:

• Whether the claim involves personal injury or property damage.
• Whether a governmental entity or employee is involved.
• Whether the injured person is a minor.
• Whether the injured person has a qualifying legal disability.
• Whether the accident caused a death.
• Whether a special statutory deadline applies.
• When the cause of action legally accrued.

The safest approach is to have an attorney evaluate the applicable deadline as soon as possible after the accident.

2. When Does the Two-Year Deadline Begin?

In most car accident personal injury cases, the limitations period begins when the cause of action accrues, ordinarily on the date of the accident.

For example, if you were injured in a rear-end collision on March 10, 2026, the ordinary two-year limitations period would generally expire on March 10, 2028.

You should not assume that the deadline begins when:

• You finish medical treatment.
• Your doctor releases you from care.
• The insurance company denies your claim.
• You receive your final medical bill.
• The insurance adjuster makes a settlement offer.
• You discover that your injuries are more serious than expected.

Illinois recognizes certain accrual and discovery principles in appropriate circumstances, but those rules do not automatically extend the deadline merely because treatment continues or an injury becomes more expensive.

For most ordinary car accident cases, the accident date is the starting point for evaluating the filing deadline.

3. What Happens If You Miss the Statute of Limitations?

Missing the applicable statute of limitations can have serious consequences.

If you file a lawsuit after the deadline, the defendant may assert the statute of limitations as a defense.

If the defense applies and no exception saves the claim, the court may dismiss your lawsuit.

This can happen even when:

• The other driver clearly caused the collision.
• You suffered significant injuries.
• You required surgery or extensive medical treatment.
• Your medical expenses are substantial.
• The insurance company previously discussed settlement.
• You have photographs, witnesses, and other evidence supporting your claim.

A strong liability case does not necessarily overcome an expired filing deadline.

The statute of limitations concerns when a lawsuit must be filed—not whether the defendant was negligent.

4. Does Filing an Insurance Claim Stop the Two-Year Deadline?

Generally, no.

This is one of the most important distinctions for injured motorists to understand.

Filing an insurance claim is not the same as filing a lawsuit in court.

You may report the accident promptly, submit medical records, provide photographs, and negotiate with an insurance adjuster for months.

However, those activities ordinarily do not stop the statute of limitations from running.

Consider this example.

You are injured in a collision and promptly open a claim with the at-fault driver’s insurance company.

For the next eighteen months, the insurer requests medical documentation and discusses possible settlement.

You believe the matter will resolve without litigation.

As the second anniversary approaches, the insurance company still has not made an acceptable offer.

Unless the claim is settled or an applicable legal rule changes the deadline, you may need to file a lawsuit before the limitations period expires to preserve your claim.

Do not rely on an insurance adjuster’s statements as assurance that your legal deadline has been extended.

5. Can You File a Lawsuit While Still Receiving Medical Treatment?

Yes.

You do not necessarily have to finish medical treatment before filing a personal injury lawsuit.

In many cases, an injured person continues treating while the lawsuit is pending.

This may be especially important when injuries require:

• Physical therapy.
• Pain management.
• Orthopedic treatment.
• Neurological evaluation.
• Surgery.
• Rehabilitation.
• Ongoing medical monitoring.

Your attorney may need medical records, physician opinions, and other evidence to evaluate future treatment needs and damages.

However, waiting until every medical issue is resolved can create unnecessary risk if the limitations deadline is approaching.

A lawsuit may be filed within the applicable period while the parties continue investigating damages, exchanging evidence, and exploring settlement.

6. What If the Accident Involved a Government Vehicle?

Accidents involving governmental entities or employees require particular attention.

For example, a collision may involve:

• A city-owned vehicle.
• A municipal employee driving during work.
• A county vehicle.
• A public transportation vehicle.
• A state-owned vehicle.
• Another governmental entity.

Different statutes may apply depending on the defendant and the nature of the claim.

Under 745 ILCS 10/8-101, certain civil actions against local public entities and their employees are subject to a one-year limitations period, although statutory exceptions and qualifications apply.

A separate statutory framework may govern claims against the State of Illinois.

For example, certain claims against the State may fall within the jurisdiction of the Illinois Court of Claims and involve special filing or notice requirements.

Do not assume that every accident involving a government vehicle is governed by the ordinary two-year personal injury deadline.

An attorney should identify the correct defendant, determine the appropriate forum, and evaluate the applicable deadline promptly.

7. How Long Do Minors Have to File a Car Accident Lawsuit?

Illinois law provides special protections for certain individuals who are minors when their causes of action accrue.

Under 735 ILCS 5/13-211, the ordinary limitations period may be extended for a person who was under eighteen when the cause of action accrued.

In many ordinary personal injury cases, this can allow a minor to file within two years after turning eighteen.

However, special statutory rules may apply to particular defendants and types of claims.

For example, certain claims against governmental entities may involve different limitations provisions.

Parents should also understand that claims belonging to an injured child may be legally distinct from claims belonging to a parent for expenses or other losses.

Do not assume that every claim arising from an accident involving a child can wait until the child becomes an adult.

Early legal evaluation is important.

8. What If You Did Not Discover Your Injury Immediately?

Some accident-related injuries are not immediately apparent.

For example, an individual may initially experience mild discomfort but later receive a diagnosis involving a spinal injury, traumatic brain injury, or another medical condition.

Illinois recognizes a discovery rule in appropriate cases.

Generally, that rule addresses when a person knew or reasonably should have known of an injury and that it may have been wrongfully caused.

However, the discovery rule does not automatically extend the deadline in every car accident case.

An injury becoming more painful or requiring additional treatment does not necessarily change the date on which the claim accrued.

Because these questions are highly fact-specific, an attorney should evaluate them rather than assuming the deadline begins on the date of diagnosis.

9. What If a Car Accident Causes Someone’s Death?

When a motor vehicle accident causes a person’s death, a wrongful death claim may be available under Illinois law.

The Illinois Wrongful Death Act, 740 ILCS 180/2, establishes deadlines for bringing wrongful death actions.

Many wrongful death claims are subject to a two-year limitations period measured from the date of death.

However, statutory exceptions and special rules may apply, including provisions involving certain intentional conduct and other circumstances.

A related survival claim may also be available to recover damages the deceased person could have pursued during life.

Wrongful death and survival claims are legally distinct, and their timing requirements should be evaluated separately.

Families should seek legal advice promptly to identify the proper representative, available claims, and applicable deadlines.

10. What Is the Deadline for Property Damage After a Car Accident?

Personal injury and property damage claims may have different statutes of limitations.

Under 735 ILCS 5/13-205, many Illinois actions involving damage to personal property are subject to a five-year limitations period.

For example, a claim for vehicle damage may be governed by a different limitations period from a claim for bodily injuries arising from the same collision.

However, special statutes, governmental defendants, and other circumstances may affect the applicable deadline.

Do not assume that having additional time to pursue vehicle damage also gives you additional time to pursue compensation for physical injuries.

11. Does the Statute of Limitations Apply to Hit-and-Run Accidents?

Yes.

A hit-and-run accident does not automatically eliminate the applicable filing deadline.

Even when the at-fault driver is unidentified, legal deadlines may still apply to potential claims.

Depending on the circumstances, an injured individual may have options involving:

• Uninsured motorist coverage.
• An identified at-fault driver.
• Other responsible parties.
• Additional applicable insurance coverage.

However, insurance policies may impose notice requirements, proof-of-claim obligations, arbitration procedures, or contractual deadlines that differ from the deadline for filing a negligence lawsuit.

A person injured in a hit-and-run collision should promptly review the available insurance coverage and applicable requirements.

12. What If the At-Fault Driver Has No Insurance?

When an at-fault driver is uninsured or underinsured, an injured individual may have a claim under their own uninsured motorist or underinsured motorist coverage.

These claims can involve insurance policy provisions that differ from ordinary lawsuits against negligent drivers.

For example, the policy may require timely notice, cooperation, or the initiation of arbitration within a specified period.

The enforceability of particular contractual deadlines depends on the policy and applicable law.

Do not assume that the ordinary two-year personal injury statute answers every deadline question involving uninsured or underinsured motorist coverage.

13. Can the Insurance Company Keep Negotiating After the Deadline Passes?

An insurance company may continue communicating about a claim even when a limitations issue exists.

However, continued discussions do not necessarily preserve your right to file a lawsuit.

An insurer’s willingness to negotiate should not be treated as a waiver of the statute of limitations.

In limited circumstances, legal doctrines such as equitable estoppel may affect whether a defendant can assert a limitations defense.

Those exceptions are fact-specific and should not be relied upon without legal analysis.

The best practice is to identify the applicable deadline independently and take appropriate action before it expires.

14. Why Should You Contact an Attorney Before the Deadline Approaches?

Waiting until the final weeks before the statute of limitations expires can create avoidable difficulties.

A personal injury attorney may need time to:

Investigate liability. Determine how the accident occurred and identify potentially responsible parties.

Obtain evidence. Request police reports, photographs, surveillance recordings, and witness information.

Review medical records. Evaluate the injuries, treatment history, and potential future care.

Identify insurance coverage. Determine which policies may apply.

Assess damages. Evaluate medical expenses, lost income, pain and suffering, and other recoverable losses.

Identify the correct defendants. Determine which individuals or entities should be named in the lawsuit.

Evaluate special deadlines. Identify any governmental or other statutory requirements.

Prepare and file the complaint. Take the procedural steps necessary to commence litigation.

Evidence may become harder to obtain as time passes.

Witnesses may forget details, surveillance footage may be overwritten, and physical evidence may disappear.

Protecting your legal rights involves more than simply knowing the deadline. It also requires preserving the evidence necessary to prove your claim.

15. What Should You Do Immediately After a Car Accident in Illinois?

If you are injured in a motor vehicle accident, consider taking these steps:

1. Seek medical attention. Obtain appropriate medical care and follow recommended treatment.

2. Report the accident. Contact law enforcement when required and obtain available report information.

3. Photograph the scene. Preserve images of vehicle damage, road conditions, traffic signals, and visible injuries.

4. Identify witnesses. Obtain contact information for individuals who observed the collision.

5. Preserve documents. Save medical bills, treatment records, repair estimates, receipts, and insurance communications.

6. Notify the appropriate insurance company. Comply with applicable policy requirements while avoiding speculation about disputed facts.

7. Keep track of your symptoms and expenses. Document how the injuries affect your work and everyday activities.

8. Consult a personal injury attorney. Obtain guidance concerning liability, insurance coverage, compensation, and filing deadlines.

Taking these steps can help protect both your health and your potential claim.

16. Frequently Asked Questions About Illinois Car Accident Filing Deadlines

Can I sue three years after a car accident in Illinois?

Generally, a personal injury lawsuit filed three years after an ordinary car accident may be barred by Illinois’ two-year statute of limitations. However, exceptions or different accrual rules may apply.

Does the statute of limitations start when I finish physical therapy?

Generally, no. In most ordinary car accident cases, the limitations period begins when the claim accrues, usually on the accident date.

Can I sue if the insurance company is still investigating?

Yes, if the applicable deadline has not expired and the legal requirements for filing suit are satisfied. You do not have to wait for an insurance company to finish its investigation before filing a lawsuit.

Does receiving a settlement offer extend the deadline?

Generally, no. Settlement negotiations and offers ordinarily do not suspend the limitations period.

Do I have more time if I was injured as a minor?

Possibly. Illinois provides special limitations rules for minors, but exceptions and special deadlines may apply.

Is the deadline different if a city vehicle caused the accident?

It may be. Certain claims against local public entities and employees are subject to a one-year limitations period, while other claims may be governed by different rules.

Can I file a lawsuit before I know the full extent of my injuries?

Yes. In appropriate circumstances, a lawsuit may be filed while medical treatment and evaluation continue.

Don’t Let the Statute of Limitations Cost You Your Right to Compensation

You may have a strong personal injury claim, but waiting too long to take legal action can jeopardize your ability to recover compensation.

After a car accident, your attention should be on your health, your recovery, and your family—not worrying about whether an insurance company will resolve your claim before a legal deadline expires.

Unfortunately, insurance negotiations can take time. Medical treatment may continue for months. And the insurance company’s willingness to communicate does not necessarily protect your right to file a lawsuit.

The deadline may be approaching even while your claim appears to be moving forward.
