Do I need to report a car accident in Chicago, IL?

Yes. Under Illinois law, motor vehicle accidents must be reported to law enforcement when they involve injury, death, or qualifying property damage. In practice, you should call 911 at the scene if anyone is hurt or vehicles are significantly damaged. An officer will typically prepare an official crash report, which can become important evidence in your personal injury claim. If no officer responds, drivers still have a duty to make sure the crash is properly reported under Illinois requirements. Always collect a copy of the report for your own records and for your attorney to review.
