About

Open Data Policing aggregates, visualizes, and publishes public records related to all known traffic stops to have occurred in Illinois since 2005. Data is available for most Illinois departments.

Illinois law requires agencies to report their data on a monthly basis to the IL state government; however, some datasets are incomplete or remain unreported. Where data sets are incomplete or missing from the website, it is because they have not been reported to the state. Open Data Policing does not have access to, nor does it publish, the names of officers, drivers, or passengers involved in traffic stops.
