Each driver involved in an Illinois 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, the threshold is $500. 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.
Individuals can complete their own crash report online when the crash meets specific criteria. The crash must be a single vehicle, property-damage-only crash where there were no injuries to anyone involved, and it occurred on either an Interstate or a U.S. or Illinois Route.

If you were involved in a traffic crash occurring on a freeway in the Chicago metro area (Cook County), you can file a Desk Report in person. Motorists should exchange information and be prepared to provide driver's license information, vehicle registration, proof of liability insurance, and call back phone numbers for any driver not present for a follow up investigation by Trooper. Hit and run crashes can also be taken as a Desk Report. If you are involved in a hit and run crash, do not try to follow the offending vehicle. Instead, please obtain as much detailed information as possible, and report the incident as soon as possible.
