What Should You Do After a Car Accident in Illinois?
Learn what to do after a car accident in Illinois, how to document your injuries, deal with insurance companies, and understand your legal options.

A car accident can happen in seconds, but its consequences may last for months or even years. From medical bills and vehicle damage to missed work and insurance disputes, an unexpected collision can create significant challenges for drivers and their families.
If you were involved in a car accident in Chicago, La Grange Park, Oak Brook, Deerfield, or elsewhere in Illinois, knowing what steps to take can help you protect your health, document important evidence, and understand your legal options.
Although every accident is different, taking appropriate steps after a crash may help you navigate the process and evaluate whether you have a personal injury claim.
What Should You Do Immediately After a Car Accident?
Your safety and the safety of others should be your first priority after a collision.
If you are involved in a car accident in Illinois, consider taking the following steps when it is safe to do so:
- Move to a safe location, if possible, without leaving the scene.
- Call 911 if anyone is injured or there is an emergency.
- Seek medical attention for any injuries, even if they do not initially seem serious.
- Exchange contact, driver’s license, vehicle, and insurance information with the other driver.
- Obtain the names and contact information of witnesses.
- Take photographs of the vehicles, damage, roadway, traffic signs, and visible injuries.
- Avoid making assumptions or definitive statements about who caused the accident.
Illinois law requires certain crashes involving injuries, deaths, or qualifying property damage to be reported to law enforcement. If an officer does not respond, reporting requirements may still apply. The appropriate reporting process depends on the circumstances of the crash.
Why Is Medical Attention Important After a Car Accident?
Some injuries may not be immediately noticeable after a collision. Symptoms involving the neck, back, head, or other parts of the body may appear or worsen over time.
Seeking medical attention can help identify injuries and ensure that you receive appropriate care.
Medical records may also help document:
- The nature and severity of your injuries
- When symptoms began
- The treatment you received
- Recommendations for additional care
- The effect of your injuries on daily activities
Follow your healthcare provider’s recommendations and keep copies of medical records, bills, prescriptions, and other treatment-related documents.
How Do You Document a Car Accident in Illinois?
Evidence can play an important role in determining how an accident occurred and evaluating a potential injury claim.
When possible, preserve information such as:
- Photographs and videos of the accident scene
- Vehicle damage
- Road and weather conditions
- Traffic signals and signs
- Police reports
- Witness contact information
- Medical records and expenses
- Receipts for accident-related costs
- Records of missed work or reduced income
You may also want to keep a record of how your injuries affect your daily activities and recovery.
If nearby businesses or vehicles may have captured the collision on camera, identifying that footage promptly may be helpful because some recordings are not retained indefinitely.
Who May Be Responsible for a Car Accident?
Determining responsibility for a car accident requires examining the circumstances of the collision and the conduct of those involved. Depending on the facts, potentially responsible parties may include:
The Other Driver
A driver may be responsible if their negligence contributed to the crash. Examples may include distracted driving, speeding, failing to yield, or disregarding traffic signals.
An Employer or Vehicle Owner
In some cases, an employer or vehicle owner may also have legal responsibility, depending on the driver's relationship to them and the circumstances of the accident.
Other Potentially Responsible Parties
Certain crashes may involve additional factors, such as a vehicle defect or a dangerous roadway condition. Whether another party may be liable depends on the evidence and applicable law. An investigation can help identify the parties whose conduct may have contributed to the collision.
What If the Insurance Company Contacts You After the Accident?
After a car accident, you may receive calls or requests for information from an insurance company.
Insurance companies may investigate the crash, review medical documentation, assess property damage, and evaluate claims. However, the amount an insurer offers may not necessarily reflect the full extent of an injured person's losses.
Before accepting a settlement, it is important to understand what it covers and whether it resolves future claims related to the accident.
Keep copies of correspondence, claim documents, and settlement offers. If you are unsure about a request or offer, consider seeking legal guidance before making a decision.
Can You Recover Compensation If You Were Partly at Fault?
Illinois follows a modified comparative-fault rule in negligence-based personal injury cases.
Under Illinois law, an injured person generally cannot recover damages if their contributory fault is more than 50% of the proximate cause of the injury. If their fault is 50% or less, they may recover damages, but the amount is reduced according to their percentage of fault.
For example, if a person is found 20% responsible for a crash, their recoverable damages may be reduced by 20%.
Fault is determined based on the facts and applicable law. An insurance company's assessment is not necessarily the final determination of legal responsibility.
What Compensation May Be Available After a Car Accident?
Depending on the circumstances and evidence, an injured person may seek compensation for losses related to the accident.
Potential damages may include:
- Medical expenses
- Future medical care
- Lost wages
- Reduced earning capacity
- Rehabilitation expenses
- Pain and suffering
- Disability or disfigurement
- Other economic and non-economic losses
The types and amount of compensation available depend on factors such as the injuries, their impact, the evidence, and the legal circumstances of the claim.
How Long Do You Have to File a Car Accident Lawsuit in Illinois?
Illinois generally imposes a two-year statute of limitations for personal injury lawsuits. However, exceptions may apply, and different deadlines may govern claims involving government entities, minors, or other specific circumstances.
Property damage claims may be subject to a different deadline.
Because missing an applicable deadline can affect your ability to pursue a claim, it is important to understand which time limit applies to your situation.
When Should You Contact a Car Accident Lawyer in Illinois?
You may want to seek legal guidance if you suffered injuries, face significant medical expenses, have questions about fault, or are dealing with an insurance dispute.
A car accident attorney can review the circumstances of the collision, explain applicable legal deadlines, help identify potentially responsible parties, and evaluate the evidence related to your claim.
