Hit and Run Accident in Chicago Suburbs: What to Do Next

Your first priority after a hit and run is safety. Move out of traffic if you can do so without worsening any injuries. Call 911 immediately. Tell the dispatcher that the other driver fled the scene. Give them whatever details you have — the direction the vehicle went, the make, model, color, and any part of the license plate number you remember.

Even if your injuries feel minor, request medical attention. Adrenaline masks pain. Injuries like whiplash, concussions, and internal bleeding may not produce symptoms for hours or days. The 911 call creates a timestamped official record that your accident happened and that you reported it immediately — this matters when you file your insurance claim.

Under Illinois law (625 ILCS 5/11-407), if no police officer is present at the scene, you must notify the nearest police authority by the fastest available means. For suburban Cook County, that means your local police department. If the crash occurred on an expressway like I-290, I-88, or I-355, the Illinois State Police will respond.

Evidence at a hit and run scene disappears fast. Start documenting immediately while you wait for police. Use your phone to photograph damage to your vehicle, skid marks, debris, broken glass, and the surrounding area. Take wide shots that show the intersection or road layout, and close-ups of specific damage. Photograph any paint transfer on your vehicle — this can help identify the fleeing car's make and color.

Look for surveillance cameras. Gas stations, ATMs, banks, apartment buildings, and retail stores near the scene may have cameras that captured the fleeing vehicle. Note every potential camera location — your attorney or the police can request footage before it is overwritten, which typically happens within 7-30 days depending on the business. In the Chicago suburbs, many intersections have traffic cameras that may have recorded the incident.

Talk to witnesses. Other drivers, pedestrians, and nearby business employees may have seen the vehicle or the collision. Get names and phone numbers. Ask if anyone got a photo or video. Witness statements can identify the vehicle, confirm details about the accident, and establish that you were not at fault — all critical to your claim.

A police report is practically essential for hit and run cases. It creates an official record of the accident, documents available evidence, and triggers a police investigation that may identify the other driver. Under 625 ILCS 5/11-406, you must file a written crash report with the Illinois Department of Transportation within 10 days if the crash involves injury, death, or property damage exceeding $1,500.

If officers respond to the scene, they will take your statement and create a report. If police do not respond — which can happen for property-damage-only incidents — file a report as soon as possible with your local suburban police department. Many departments, including Naperville PD (630-420-6157) and Joliet PD (815-726-2491), offer online reporting systems. For crashes on expressways, contact Illinois State Police.

Request a copy of your police report. You will need the report number for your insurance claim. If the police investigation identifies the other driver, your case shifts from a UM claim to a standard liability claim against the at-fault driver — and the hit and run charge strengthens your civil case because leaving the scene is powerful evidence of fault.

When the hit and run driver is never found, your uninsured motorist (UM) coverage steps in. Under 215 ILCS 5/143a, every auto insurance policy issued in Illinois must include UM coverage equal to your bodily injury liability limits, unless you specifically rejected it in writing. If you carry UM coverage, it pays for your medical bills, lost wages, and pain and suffering up to your policy limits.

About 16.3% of Illinois drivers carry no insurance at all (Insurance Research Council, 2022). Even when a hit and run driver is identified, they frequently turn out to be uninsured. UM coverage protects you in both scenarios. File your UM claim promptly. Your insurance company will investigate the accident, review your police report, and evaluate your injuries before making a settlement offer.

Be aware that your own insurance company is not on your side in a UM claim. They owe you coverage under your policy, but their financial interest is to pay as little as possible. Document everything — medical records, bills, lost wages, pain journal — and do not accept the first settlement offer without understanding the full value of your claim. If the hit and run driver is later identified and has insurance, your UM carrier may have a subrogation right to recover from their insurer.

Illinois treats leaving the scene of an accident as a serious criminal offense under 625 ILCS 5/11-401. Every driver involved in an accident must stop immediately, exchange information, render reasonable assistance to injured persons, and report the accident within 30 minutes. Failing to do so triggers criminal penalties that escalate sharply with injury severity.

For property-damage-only accidents, leaving the scene is a Class A misdemeanor under 625 ILCS 5/11-402 (up to 12 months in jail and a $2,500 fine). If the accident causes personal injury, the charge rises to a Class 4 felony (1-3 years in prison, up to 6 years with aggravating factors). If the driver fails to report an injury crash, it becomes a Class 2 felony (3-7 years). If the crash results in death, the charge escalates to a Class 1 felony (4-15 years in prison).

As the victim, a criminal conviction against the hit and run driver strengthens your civil claim. A guilty plea or conviction can prevent the defendant from denying fault in your personal injury lawsuit. While the criminal case does not directly compensate you, it creates a record that is admissible in civil proceedings and shifts the liability question decisively in your favor.

Suburban police departments and the Illinois State Police investigate hit and run cases, and drivers are identified more often than victims expect — through surveillance footage, license plate readers, witness tips, paint transfer analysis, or the driver's own vehicle damage leading to a body shop tip. If the driver is found, your claim changes significantly.

Once the driver is identified, you file a liability claim against their auto insurance (if they have it). The hit and run itself is powerful evidence of negligence and consciousness of guilt. A driver who fled the scene will have difficulty arguing they were not at fault. If the driver is uninsured, you can still pursue a civil lawsuit against them personally, though collecting a judgment from an uninsured driver can be difficult. Your UM coverage remains available as a backstop.

Illinois's modified comparative negligence system (735 ILCS 5/2-1116) still applies. If you are found partially at fault, your damages are reduced by your fault percentage. If you are 50% or more at fault, you recover nothing. In hit and run cases, the fleeing driver almost always bears the overwhelming majority of fault — the act of leaving the scene itself demonstrates irresponsibility and consciousness of guilt.

Illinois's statute of limitations for personal injury claims is 2 years from the date of injury (735 ILCS 5/13-202). This deadline applies whether the hit and run driver is identified or not. For wrongful death claims, the deadline is also 2 years from the date of death. For property damage, the deadline extends to 5 years. These are hard deadlines — miss them and your claim is permanently barred.

If a government vehicle was involved in the hit and run — a municipal vehicle, county truck, or state car — you must file a tort claim notice within 1 year under the Local Governmental and Governmental Employees Tort Immunity Act (745 ILCS 10/). For your insurance claim, check your UM policy for notice and filing deadlines — most policies require prompt notice and cooperation with the investigation.

Do not assume the 2-year statute of limitations gives you time to wait. Evidence disappears, witnesses forget details, and surveillance footage gets overwritten. The strongest hit and run claims are the ones that start building their evidence file on day one.
