On July 18, 2003 a new Senate Bill was signed into law. This law established a four year statewide study of traffic stops to collect data to identify racial bias. The study began on January 1, 2004 and was originally scheduled to end December 31, 2007. However, Public Act 98-0686 has extended the Illinois Traffic Stop Study. All Illinois law enforcement agencies must continue to collect and submit traffic stop data until July 1, 2019.
IDOT is responsible for collecting and compiling the data. IDOT has developed an Internet self-reporting application for submission of the data. Agencies have two options for entering data into the IDOT data collection system.
Agencies using their own applications are encouraged to upload their data to IDOT at least once a month.
All agencies will need to be registered in order to enter or upload data using this website. They will also need to be registered in order to download the standalone applications. In order to register, please call Suzanne Hulett at (217) 785-2364.

Disclaimer: Each reporting law enforcement agency was responsible for the accuracy of their own data that was submitted to the IDOT.
To obtain a copy of the data, email IDOT at DOT.ITSS@illinois.gov, and your request will be forwarded to the department’s FOIA Officer.
