Police Traffic Stops. Each record records the information about a driver who was stopped, as captured for the Illinois Department of Transportation (IDOT) Traffic Stop program. In addition to the fields captured for IDOT, these records include the incident code recorded in the stop. Data goes back to 2012, when IDOT began using the current reporting layout.
