Illinois Traffic Crash Reports are made by the police when a vehicle is involved in a collision (See an example Illinois Traffic Crash Report here). They are used for vehicle crashes, vehicle collisions with a pedestrian, and vehicle collisions with a bicyclist. If police are called to the scene of a collision, an Illinois Crash Report will be filled out. A more detailed report will be made if there is a death, serious injury, or if a vehicle has to be towed from the scene.
The basic information included in the Crash Report is the street or intersection where the accident occurred, the municipality where the accident occurred, the county where the accident occurred, as well as the date, and the time of the accident. This information can be found in the box at the top of the report.
