Filing a Police Report After an Illinois Hit and Run

A hit and run accident leaves you standing in a parking lot or on the side of the road, staring at damage with no other driver in sight. It's frustrating, stressful, and confusing. But what you do next especially whether you file a police report can make or break your ability to recover costs for vehicle repairs, medical bills, and other losses. In Illinois, filing a police report after a hit and run isn't just a good idea. It's often a legal requirement and a critical step for protecting your insurance claim and your rights.

Is Filing a Police Report Required After a Hit and Run in Illinois?

Yes, under Illinois law, you are required to report any motor vehicle accident that results in injury, death, or property damage exceeding $1,500 to local law enforcement. A hit and run collision almost always meets this threshold. Even if the damage seems minor, filing a report creates an official record that your insurance company will likely need before processing any claim related to the incident.

Under 625 ILCS 5/11-403, drivers involved in accidents must notify police. When the other driver has fled the scene, you become the only person who can initiate that report. Failing to report could hurt your claim later, especially if you're seeking compensation through your uninsured motorist coverage.

When Should You File the Report?

File as soon as possible ideally at the scene or within 24 hours of discovering the damage. Some people find their parked car hit in a lot or on the street, with no note left behind. In those cases, file the report the moment you discover the damage.

The longer you wait, the harder it becomes for police to investigate. Security camera footage gets overwritten. Witnesses forget details. Tire marks fade. A quick report gives law enforcement the best chance of identifying the driver who hit you.

How Do You File a Police Report for a Hit and Run in Illinois?

You have two main options depending on where the accident happened and whether anyone was injured.

Option 1: Call 911 at the Scene

If you're present when the hit and run occurs say, another vehicle strikes yours at an intersection and speeds away call 911 immediately. Give the dispatcher your location, a description of the fleeing vehicle (make, model, color, license plate if you caught it), and the direction it headed. Officers will respond, take your statement, and file a report on the spot.

Option 2: File a Report at the Police Station

If you discover your vehicle was hit while parked, or if the accident wasn't an emergency, you can walk into your local police department and file a report in person. Many Illinois departments also allow you to file certain types of reports online or over the phone, though in-person filing is generally better for hit and run cases because you can provide physical evidence and ask questions.

When you go, bring:

Your driver's license and vehicle registration
Photos of the damage to your vehicle
Any witness names and contact information
The approximate time and location of the accident
A description of the other vehicle, if you have one

Option 3: Illinois State Police Reports

If the hit and run happened on a state highway or expressway, you may need to file with the Illinois State Police rather than a local department. You can contact the district office that covers the area where the crash occurred.

What Information Should You Include in the Report?

Be as specific and factual as possible. Police reports are legal documents, and the details you provide will be used by investigators and insurance adjusters. Include:

Date, time, and exact location of the accident (street names, intersections, parking lot name)
Vehicle damage description which parts of your car were hit, how severe the damage is
Other vehicle details even partial information helps. A color, a partial plate number, or the make of the vehicle can narrow the search
Witness information anyone who saw the accident happen
Surveillance cameras note nearby businesses or traffic cameras that may have recorded the incident
Weather and road conditions at the time

Don't guess or assume details you're unsure about. Stick to what you actually saw or know. If you didn't get a good look at the other vehicle, say so. Accuracy matters more than completeness.

What Happens After You File the Report?

Once the report is filed, police will assign a case number. Keep this number your insurance company will ask for it. Officers may investigate by reviewing camera footage, checking for paint transfers on your vehicle, or canvassing the area for witnesses.

Be realistic about outcomes. Hit and run investigations are difficult, especially when there's limited evidence. According to the National Highway Traffic Safety Administration, roughly 11% of all reported crashes involve a hit and run driver, and many are never identified. But filing the report is still essential it documents the incident and supports your insurance claim regardless of whether the driver is found.

Understanding what happens if the driver is eventually caught without insurance in Illinois can help you understand why that police report matters even more.

Do I Need a Police Report to File an Insurance Claim?

Most insurance companies in Illinois require a police report number before they'll process a hit and run claim. This is especially true if you're filing under your uninsured motorist property damage (UMPD) or collision coverage. Without a report, your insurer may question whether the damage actually resulted from a hit and run or they may deny the claim entirely.

If the other driver is never found, your uninsured motorist coverage options after a hit and run collision become the primary path to recovering your losses. That police report is the foundation those claims are built on.

What If the Accident Happened in a Parking Lot?

Parking lot hit and runs are extremely common in Illinois. Someone dings your door, scrapes your bumper, or backs into your car and drives off without leaving a note. You file the report the same way through local police, either in person, by phone, or online depending on the department.

One important detail: if the accident happened on private property like a shopping center parking lot, some police departments may initially say they can't respond. Push back. Illinois law still requires reporting. You can also ask the property owner or management company for security camera footage, which can be turned over to police as part of the investigation.

What If the Hit and Run Caused Injuries?

If you or a passenger suffered injuries, the report becomes even more critical. Emergency responders will typically create their own incident report, but you should still follow up with a formal police report that documents the accident as a hit and run. This report will be needed for both your insurance claim and any potential legal action.

Medical documentation should be started immediately. Even if injuries seem minor soreness, stiffness, headaches get evaluated by a doctor. Some injuries from vehicle collisions don't show symptoms right away, and gaps in medical treatment can be used against you later.

Common Mistakes People Make With Hit and Run Reports

Waiting too long to file. The sooner you report, the better the chances of catching the driver and preserving evidence.
Chasing the fleeing driver. This is dangerous and can put you at fault for additional accidents. Get the plate number if you safely can, but don't pursue.
Failing to document the scene. Take photos of everything your car, the road, any debris, paint marks on your vehicle. This evidence supports your report.
Not getting the report number. Always ask for and write down your case or report number. You'll need it repeatedly.
Assuming minor damage doesn't need a report. Even small damage can cost thousands to repair, and without a report, you may have no way to recover those costs.

Can You Still Pursue the Other Driver After Filing?

Absolutely. The police report starts the investigation, but it doesn't limit your options. If the driver is identified later, you can pursue them for damages through their insurance or through the courts. Illinois allows you to sue an uninsured driver for a hit and run in small claims court, which can be a practical option when insurance doesn't cover everything.

If you need guidance on the broader steps to take after the incident, reviewing what to do after a hit and run accident with an uninsured driver can help you understand the full process from start to finish.
