The information is the same data transmitted to the Illinois Department of Transportation (IDOT) with two additions: the "Motivation for Stop", and the offense codes recorded.
IMPORTANT!! (please click "More" to read this...) Adding the Offense Codes means that each line of information represents a single Offense.
For example: a traffic stop for speeding results in an arrest for an outstanding warrant and for possession of narcotics. That would appear on this listing THREE times (speeding, arrest warrant, and narcotics). The Incident Number will be the same (and the driver demographics), but the Crime Codes will be different on each line.
So counting rows of this dataset will return a higher count than the actual stops. This will cause some discrepancies with State data, which only count each stop once.

This chart shows the arrest resolution to crimes classified under Drug Control Acts (taken to jail, given a "notice to appear", released on I-Bond, etc.) One item that impacts the arrest resolution is the possibility of other crimes in the incident. A driver stopped for a DUI who also is cited for possession of drugs might be taken to jail (because of the DUI) whereas possession would normally result in a "Notice to Appear"
