Illinois Law and When You Must Report a Bicycle Accident
Illinois does not leave crash reporting to personal preference. Under Illinois law, each driver involved in a traffic crash must file a crash report if the crash caused a death, bodily injury, or more than $1,500 of property damage when all drivers are insured. If any driver does not have insurance, that threshold drops to just $500. These thresholds are lower than most people expect, which means the vast majority of bicycle accidents in Chicago trigger a legal reporting obligation.
The relevant provision is found in the Illinois Vehicle Code under 625 ILCS 5/11-407. That statute requires drivers to report a vehicle crash to the local police department or the Illinois State Police within ten days of the crash if there were significant injuries or property damage exceeding $1,500. If you were hit near Millennium Park, on Milwaukee Avenue, or anywhere else in the city, this law applies to the driver who struck you. It also applies to you as a cyclist involved in the crash.
If a police officer does not appear on the scene, you need to file a report with the Illinois State Police as soon as possible, within 10 days. That said, waiting is rarely a good idea. Calling 911 immediately gets an officer to the scene who can document conditions, gather witness information, and create an official record while the evidence is still fresh. The longer you wait, the harder it becomes to prove what actually happened. Do not assume the other party will file an accurate report on your behalf. Protect your own interests from the start.
Illinois law also places duties on drivers involved in crashes under 625 ILCS 5/11-401. Section 11-401(a) of the Illinois Vehicle Code requires motorists involved in a bike accident to remain at the scene. If the driver who hit you left, that is a separate criminal issue, and it makes calling the police even more urgent. An official report documents the hit-and-run, which is critical for pursuing uninsured motorist coverage later.
Why You Should Always Call the Police, Even for Minor Accidents
Cyclists often talk themselves out of calling the police when they feel okay right after a crash. That instinct can be costly. Adrenaline masks pain, and injuries like concussions, herniated discs, and internal bleeding may not become obvious for hours or even days. By the time symptoms appear, the scene is gone, witnesses have scattered, and the driver may have changed their story entirely.
A police report creates an official, third-party record of the crash. The accident report contains information about where the crash happened, who was involved, who witnessed it, and who was injured. It may also provide information about negligence on the part of the motor vehicle driver, for example, whether the driver received a ticket for speeding or failing to yield the right-of-way. That kind of documented evidence is hard to dispute in court or during insurance negotiations.
Insurance companies pay close attention to police reports. Without a police report, the likelihood that an insurance company will accept your claim decreases significantly. Adjusters look for any reason to minimize or deny a payout, and the absence of a report gives them room to argue that the crash was not serious or that your injuries came from somewhere else. A report filed the same day eliminates that argument.
Think about what happens on a busy street like North Clark Street or Damen Avenue, where traffic is constant and witnesses move on quickly. The officer who responds can canvass the area, speak with bystanders, and record conditions you might miss while you are dealing with shock and pain. That documentation becomes part of the official Illinois Traffic Crash Report, a standardized form that insurance companies and courts rely on when evaluating bicycle accident claims. You cannot recreate that record after the fact, so call 911 while you are still at the scene.
What Happens When the Driver Flees the Scene
Hit-and-run crashes are a serious and growing problem on Chicago streets. According to crash data covering 2022 through 2025, 2,393 cyclists were hit by drivers who did not stop across that four-year period, representing 28.5% of all reported bicycle crashes. In 2025 alone, drivers struck a cyclist and fled 694 times, a 39.6% increase from 2022. Calling the police immediately after a hit-and-run is one of the most important steps you can take.
When you call 911, give the dispatcher as much detail as possible: the vehicle’s color, make, direction of travel, and any partial plate numbers you caught. Even a general description helps investigators. An officer who arrives quickly may be able to locate the driver before they get far. Traffic camera footage from city intersections, business surveillance systems, and dashcam recordings from other vehicles can all be pulled faster when law enforcement is involved early.
A police report also opens the door to uninsured motorist (UM) coverage. Many cyclists do not realize this coverage can apply even when the driver is unknown. If you own a vehicle with UM coverage, or if a household family member does, that policy may cover your medical bills and other losses. Without a police report documenting the hit-and-run, insurers often refuse to process those claims. The report is not just a formality. It is the foundation of your legal options when the driver cannot be identified.
A Chicago bike accident lawyer can help you understand what coverage applies in your specific situation and handle communications with the insurance company so you do not inadvertently say something that undermines your claim.
What to Do While Waiting for Police to Arrive
The minutes between calling 911 and the officer’s arrival are valuable. Use them wisely. First, move yourself out of traffic if you can do so safely. If you are near a busy corridor like Halsted Street or North Avenue, staying in the roadway puts you at further risk. Get to a sidewalk or protected area, but do not leave the scene.
Take photos of everything. Photograph the vehicle that hit you, the road surface, any skid marks, traffic signals, bike lane markings, your bicycle, your clothing, and any visible injuries. These images capture conditions that will change or disappear quickly. If there are witnesses, ask for their names and phone numbers before they walk away. Do not assume the police will get witness information for you. In a case where the question of fault depends on your word against the driver’s, an independent witness makes all the difference.
When the officer arrives, provide a clear and factual account of what happened. Even if you only have a scratch, make sure it is noted in the accident report. Ask the responding officer for their name, badge number, and report number. Do not admit fault or apologize, even if you feel partly responsible. Fault is a legal determination that takes into account Illinois comparative fault rules, driver behavior, road conditions, and other factors. Let the investigation run its course before drawing any conclusions.
After the officer leaves, seek medical attention right away. Even if you feel fine, get evaluated. Some injuries, including traumatic brain injuries and spinal cord damage, may not produce obvious symptoms immediately. A same-day medical record connects your injuries to the crash, which is critical for any personal injury claim you later pursue.
How a Police Report Supports Your Personal Injury Claim
The Illinois Traffic Crash Report generated after a bicycle accident is one of the most powerful documents in a personal injury case. It captures details that are nearly impossible to reconstruct later, including the officer’s assessment of contributing factors, any citations issued to the driver, witness contact information, and a diagram of the crash scene. Insurance companies read these reports carefully when determining the value of your claim. That is why it is important to make sure the information in it is accurate.
Driver negligence is the legal foundation of a bicycle accident personal injury claim in Illinois. Behaviors like failing to yield the right-of-way, running red lights, improper passing, and distracted driving are all documented in the crash report when an officer investigates properly. According to crash data from 2022 through 2025, failing to yield right-of-way was the single most identifiable cause of Chicago bicycle crashes, accounting for 2,165 incidents and linked to 1,777 injuries. When an officer records that a driver ran a stop sign or failed to yield, that becomes evidence of negligence that supports your claim for medical expenses, lost wages, and pain and suffering.
Illinois operates under a modified comparative fault system, meaning your compensation is reduced by your percentage of fault. If you are found more than 50% responsible, you cannot recover anything. A thorough police report that accurately reflects driver misconduct protects you from inflated fault assignments by insurance adjusters. It also gives your attorney a solid starting point for building your case.

FAQs About When to Call the Police After a Bicycle Accident in Chicago
Do I have to call the police after a bicycle accident in Chicago if I feel fine?
You should call the police regardless of how you feel. Illinois law requires crash reporting when there is bodily injury or property damage over $1,500, and many injuries do not become apparent until hours after the crash. A police report also protects your right to file an insurance claim or personal injury lawsuit later. Skipping the report can seriously damage your case.
What if the driver who hit me drove away before police arrived?
Call 911 immediately and report the hit-and-run. Give the dispatcher as much detail as possible about the vehicle. A police report documenting the hit-and-run is essential for accessing uninsured motorist coverage under your own auto insurance policy or a household family member’s policy. Without that report, insurers often deny hit-and-run claims outright.
How long do I have to file a police report after a bicycle accident in Illinois?
Under 625 ILCS 5/11-407, drivers involved in a crash with injuries or significant property damage must report the crash to the local police department or the Illinois State Police within 10 days. However, calling 911 immediately is always better. Evidence disappears quickly, and an on-scene investigation produces a far more complete and useful report than one filed days later.
Can I get a copy of the police report after my bicycle accident?
Yes. You can request a copy of your Illinois Traffic Crash Report through the Chicago Police Department’s online portal for a $6 fee. You will need the report number, the date of the crash, or the names of the people involved. Reports filed before 2016 must be requested in person at the Chicago Police Department Records Customer Service Section at 3510 South Michigan Avenue, Chicago, IL 60653.
What should I do if the police report contains errors about my bicycle accident?
Review your report carefully as soon as you receive it. Check the location, time, fault determination, and witness information. Errors in a police report can be used against you by insurance companies to reduce your compensation. If you find mistakes, an attorney can help you challenge inaccurate entries and submit a supplemental statement to correct the record before your claim moves forward.
