What to Do After a Car Accident in Illinois

A Step-by-Step Guide to Handling a Car Accident in Illinois

Being involved in a car accident can be an overwhelming experience. In the moments following a collision, you may have questions about your safety, injuries, vehicle damage, insurance coverage, and the steps required under Illinois law.

Whether an accident occurs on a busy Chicago street, an Illinois highway, or a residential road in Cook County, knowing what to do can help you respond appropriately and protect important information.

After a car accident in Illinois, your first priorities should be checking for injuries, getting to safety, notifying law enforcement when required, and documenting the collision. You should also exchange information with the other driver, contact your insurance company, and preserve records that may become relevant later.

This guide explains the steps to take after a car accident in Illinois, current accident-reporting requirements, how insurance claims work, and when additional legal guidance may be appropriate.

1. Check for Injuries and Ensure Everyone’s Safety

Your immediate priority after a car accident is to determine whether anyone needs emergency medical assistance.

Stop your vehicle, remain calm, and check yourself and your passengers for injuries.

If anyone is seriously injured, unconscious, experiencing difficulty breathing, or otherwise requires emergency assistance, call 911 immediately.

Provide the dispatcher with your location, the number of vehicles involved, and any information you have about injuries or roadway hazards.

Avoid moving someone who may have a serious injury unless remaining in place presents an immediate danger. Follow the directions of emergency responders.

Should You Move Your Car After an Accident?

Whether you should move your vehicle depends on the accident circumstances.

For property-damage-only accidents, Illinois law requires drivers to make reasonable efforts to move damaged vehicles out of traffic when appropriate and safe.

Under 625 ILCS 5/11-402, drivers involved in qualifying property-damage accidents must take reasonable measures to avoid obstructing highway traffic.

However, collisions involving injuries or fatalities may create additional legal responsibilities.

If it is unsafe to move your vehicle, remain in a secure location and follow instructions from law enforcement or emergency personnel.

Do not put yourself in danger to retrieve personal belongings or photograph the scene.

2. Report the Car Accident to Law Enforcement When Required

Understanding Illinois car accident reporting requirements is an important part of responding to a collision.

Not every minor incident follows the same reporting procedure. Illinois law establishes circumstances in which a driver must notify law enforcement.

Under Illinois Vehicle Code Section 11-407, drivers must notify the appropriate law enforcement agency when an accident involves:

  • Injury to or death of any person.
  • Property damage exceeding $1,500 when the vehicles are covered by the required liability insurance.
  • Property damage exceeding $500 when a vehicle required to carry liability insurance is uninsured.
  • Certain accidents involving school buses.

When a crash meets the statutory criteria and no officer is present, Illinois law requires prompt notification through the fastest available means.

For accidents within a municipality, contact the local police department. For accidents outside municipal boundaries, contact the appropriate county sheriff’s office or Illinois State Police.

If an accident involves injuries, serious hazards, or an immediate emergency, call 911.

Is an Illinois Motorist Report Still Required?

One common source of confusion is the difference between notifying law enforcement and completing an Illinois Motorist Report.

The Illinois Department of Transportation (IDOT) eliminated the general requirement for motorists to complete and submit the former SR1B Illinois Motorist Report.

This change was established through Public Act 102-0560.

However, drivers are still responsible for complying with applicable law enforcement crash-reporting requirements.

The elimination of the former SR1B requirement does not mean that all car accidents can go unreported.

For current official information, visit the Illinois Department of Transportation’s Crash Reports page.

What If Police Do Not Respond to the Scene?

If no officer comes to investigate an accident that meets the reporting criteria, contact the appropriate police agency for instructions.

The Illinois State Police crash-reporting resource explains how certain crashes can be reported and identifies procedures for accidents occurring on state highways and Chicagoland freeways.

Illinois State Police advises drivers to report qualifying crashes as soon as possible and describes a 10-day window for certain reporting procedures.

This does not replace the obligation to provide prompt notification when required by Illinois law.

Some single-vehicle, property-damage-only accidents may qualify for online reporting through the Illinois State Police system.

However, the online system does not accept two-vehicle crashes, and additional eligibility restrictions apply.

If you are uncertain about the appropriate procedure, contact the agency responsible for the accident location.

3. Exchange Contact and Insurance Information

Once emergency concerns have been addressed, exchange the necessary information with the other drivers.

Illinois law requires drivers involved in applicable accidents to provide identifying information and comply with other duties established under the Vehicle Code.

In practice, you should record:

  • The other driver’s full name and contact information.
  • Driver’s license details.
  • Vehicle registration and license plate information.
  • Vehicle make, model, and color.
  • Insurance company and policy information.
  • The vehicle owner’s information, if different from the driver.

Remain calm and communicate respectfully.

Avoid arguments about who caused the collision. Responsibility for an accident may depend on evidence, witness statements, insurance investigations, and applicable law.

If another driver becomes aggressive or refuses to cooperate, contact law enforcement rather than escalating the situation.

Use an Accident Information Checklist

It can be difficult to remember every important detail after a stressful collision.

A structured accident checklist can help you record information consistently.

The Law Offices of Timothy Henderson provides a Car Accident Information Form that identifies useful details such as vehicle information, witnesses, road conditions, police involvement, and visible damage.

You can use the form’s categories as a reference when organizing your accident notes.

Because online forms may collect personal information, review the relevant privacy information before submitting sensitive details.

4. Take Photos and Document the Accident Scene

Accident documentation can provide useful context when you later speak with your insurance company, request repairs, or review what happened.

If it is safe to do so, photograph the accident scene from several angles.

Capture visible damage to each vehicle, vehicle positions, lane markings, traffic signs, signals, debris, and relevant roadway conditions.

Photographs taken immediately after a collision may preserve details that change once vehicles are moved or the roadway is cleared.

Record Witness Information

If someone witnessed the accident, ask whether they are willing to provide contact information.

An independent witness may have observed details that the drivers did not see.

Record the witness’s name and a reliable contact method if they agree.

Do not pressure witnesses to make statements or suggest what they should say.

Write Down What Happened

As soon as practical, write down your recollection of the collision.

Include the location, approximate time, direction of travel, weather conditions, and sequence of events.

If you noticed road construction, poor visibility, unusual traffic conditions, or another relevant factor, make a note of it.

Save your original photographs, notes, and digital files in a secure location.

For a practical overview of scene documentation, review Tim Henderson’s Steps to Follow After an Accident Has Occurred guide.

5. Seek Appropriate Medical Attention

Medical care is an important consideration after a motor vehicle collision.

Although some injuries are immediately apparent, other symptoms may not become noticeable until later.

For example, a person involved in a collision might experience headaches, stiffness, dizziness, back pain, or changes in mobility.

The appropriate response depends on the symptoms and the circumstances of the accident.

Seek emergency assistance for severe symptoms or potentially serious injuries. For other medical concerns, consult a qualified healthcare professional for an evaluation.

Do not assume an injury is insignificant solely because the vehicle sustained limited visible damage.

Keep Your Medical Records Organized

If you receive medical treatment following an accident, maintain copies of relevant records.

These may include physician reports, discharge instructions, medical bills, prescriptions, appointment information, and treatment recommendations.

Keeping accurate documentation can help you manage your medical care and respond to legitimate insurance questions.

If your symptoms worsen or you develop new concerns, contact your healthcare provider.

Medical decisions should be based on your health needs rather than on the possibility of making an insurance claim.

6. Obtain the Police Crash Report

A police crash report can be an important document after an Illinois car accident.

Depending on the circumstances, it may identify the vehicles involved, accident location, participating drivers, and observations made during the investigation.

If an officer responds, ask for the officer’s name, agency, and crash report number when available.

The process for obtaining the report depends on which department investigated the collision.

How Do You Get a Crash Report in Illinois?

For an accident investigated by Illinois State Police, use its official Crash Report Request page.

Illinois State Police provides procedures for requesting certain reports online or by mail.

If a municipal police department or county sheriff investigated the collision, contact that agency for records-request instructions.

For example, a collision handled by the Chicago Police Department would ordinarily require contacting the relevant Chicago reporting authority rather than assuming the Illinois State Police maintains the report.

Keep your report number and related correspondence for future reference.

Remember that a police report does not necessarily determine the final legal responsibility of every person involved.

7. Notify Your Insurance Company and Understand the Claims Process

After attending to safety and medical needs, contact your automobile insurance company according to your policy requirements.

Be prepared to provide the accident date, location, vehicle information, and available documentation.

Maintain a record of communications with your insurer.

Keep claim numbers, emails, repair estimates, and written explanations of coverage decisions together.

First-Party and Third-Party Insurance Claims

A first-party claim is generally made under your own insurance policy.

A third-party claim is made against another driver’s insurance company.

The two types of claims involve different rights and responsibilities.

Depending on your coverage and the circumstances, you may be able to pursue repairs or other covered losses through your insurer or another driver’s liability insurer.

The Illinois Department of Insurance guide to filing a claim with another driver’s insurance company explains the differences between these claims.

Can You Choose Your Own Repair Shop?

Illinois Department of Insurance guidance explains that consumers are generally not required to use a repair facility selected by the insurance company.

However, differences between repair estimates and the insurer’s approved amount may affect out-of-pocket costs.

Before authorizing repairs, review your policy, applicable deductibles, estimates, and communications from the claims representative.

Be Careful Before Signing a Settlement Release

An insurance company may offer a settlement after reviewing the accident and claimed damages.

Before accepting an offer, read any proposed release carefully.

A release may limit your ability to seek additional payment for the matters it covers.

If medical treatment is ongoing, there may be uncertainty about future expenses or the full impact of an injury.

Consider seeking appropriate advice before entering into a final agreement that you do not fully understand.

No particular settlement result can be guaranteed.

8. Keep Records of Accident-Related Expenses

A car accident can lead to several types of expenses.

Depending on the circumstances, these may include vehicle towing, repairs, transportation, medical treatment, and replacement of damaged property.

Maintain receipts, invoices, repair estimates, and other relevant records.

If an injury affects your ability to work, keep appropriate records of missed work and related employment information.

It may also help to create a chronological file that includes the accident date, medical appointments, insurance communications, and significant developments.

Why Is Accurate Documentation Important?

Organized records can help you understand the financial effects of an accident and provide supporting information during insurance discussions.

However, an expense is not automatically recoverable simply because it occurred after a collision.

Whether an insurer must pay a particular expense or whether an amount may be legally recoverable depends on the applicable coverage, liability, evidence, and circumstances.

For broader information about legal issues arising from injuries, see the Law Offices of Timothy Henderson’s Personal Injury overview.

9. Understand Special Accident Situations in Illinois

Some collisions involve additional safety concerns or reporting questions.

The following situations deserve particular attention.

Hit-and-Run Accidents

If another driver leaves the scene without providing the required information, notify law enforcement promptly.

Record any details you can safely remember, including the vehicle’s appearance, license plate, and direction of travel.

Do not attempt to chase the vehicle.

If there are witnesses or nearby cameras, note their locations.

Also notify your insurance company and ask whether relevant coverage may apply.

Accidents Involving Uninsured Drivers

If another driver does not have the required liability insurance, additional reporting considerations may apply.

Illinois uses a lower property-damage reporting threshold when a vehicle required to be insured is uninsured.

Contact the appropriate law enforcement agency if the statutory reporting criteria are met.

You should also review your insurance policy to determine whether uninsured motorist or other relevant coverage applies to your circumstances.

Illinois generally requires minimum automobile liability coverage of $25,000 per person and $50,000 per accident for bodily injury, plus $20,000 for property damage.

These limits are commonly expressed as 25/50/20.

For current coverage requirements and insurance guidance, consult the Illinois Department of Insurance.

Accidents Involving Parked Vehicles

If you strike an unattended vehicle, Illinois law imposes specific duties.

These generally include stopping, attempting to locate or notify the owner, providing the required identifying information, and notifying the appropriate police authority.

Review 625 ILCS 5/11-404 for the statutory requirements.

Do not assume that leaving without taking further action is acceptable simply because the other vehicle was unattended.

Accidents on Chicago Expressways

Crashes on interstates and expressways may be handled differently from collisions on municipal streets.

Illinois State Police provides guidance for certain crashes on Chicagoland freeways, including desk-report procedures.

The appropriate response depends on the location, severity, and whether an officer investigated the accident.

Check the latest Illinois State Police guidance rather than assuming that every crash can be reported online.

10. Understand Illinois Accident-Related Legal Deadlines

The time available to pursue an accident-related legal claim varies depending on the nature of the case.

Under 735 ILCS 5/13-202, many Illinois personal injury lawsuits are subject to a two-year statute of limitations.

The Illinois Department of Insurance also explains that many property-damage lawsuits are subject to a five-year limitations period.

However, different deadlines or exceptions may apply to claims involving minors, public entities, or other circumstances.

Insurance policy deadlines and requirements may also differ from the deadlines for filing a lawsuit.

Do not assume that every claim arising from a car accident is governed by the same deadline.

If a potential legal claim is involved, an Illinois attorney can help evaluate the specific time limits that may apply.

11. Common Mistakes to Avoid After an Illinois Car Accident

The hours and days following a collision can involve numerous decisions.

Being aware of common mistakes may help drivers avoid unnecessary problems.

Failing to Report an Accident When Required

Do not assume an accident is exempt from reporting simply because the vehicles remain drivable.

Property damage may exceed the applicable reporting threshold even when it appears minor.

Contact the appropriate law enforcement agency if you are uncertain.

Losing Important Documentation

Accident photographs, insurance information, medical records, repair estimates, and witness details may become difficult to locate later.

Keep copies in a secure location and organize them as soon as practical.

Ignoring Medical Symptoms

Do not overlook symptoms that may require medical attention.

Follow the advice of qualified healthcare professionals, particularly if you experience persistent or worsening symptoms.

Signing Documents Without Understanding Them

Insurance documents, releases, and other forms can have important consequences.

Read documents carefully and ask questions before signing.

Making Unsupported Statements About Responsibility

When discussing the collision, focus on facts you personally know.

Avoid speculation about another person’s actions or legal fault.

Provide accurate information to law enforcement and insurers.

Sharing Too Much Information Online

Consider the privacy implications of publishing accident photographs, medical details, or extensive descriptions of the collision on social media.

Information shared publicly can be difficult to remove later.

12. Illinois Car Accident Checklist: The First 48 Hours

The first two days after a crash can be stressful.

Using a structured checklist may help you prioritize important tasks.

Immediately After the Accident

Stop your vehicle, assess injuries, and request emergency assistance if needed.

Move to safety when appropriate and lawful.

Notify law enforcement when required and exchange identifying information with other drivers.

Document the scene if it is safe to do so.

Within the First Several Hours

Seek appropriate medical care.

Make arrangements for an undriveable vehicle, including towing or storage if necessary.

Preserve photographs, contact information, and any documents provided by the responding officer.

Notify your insurance company according to your policy.

Within the First Day

Write down your recollection of the accident while the details remain fresh.

Organize accident photographs, police information, medical records, and insurance communications.

Determine how to request the crash report.

Check whether additional reporting steps are necessary.

During the Following Days

Continue any recommended medical follow-up.

Keep records of accident-related expenses and insurance communications.

Review repair estimates and proposed settlement documents carefully.

If significant injuries, disputed fault, or complicated legal questions arise, consider whether professional advice would be helpful.

Remember that some accident-reporting obligations require prompt action. A 48-hour checklist is an organizational tool, not a substitute for statutory deadlines.
