The Illinois State Police may not require an Illinois State Police officer to issue a specific number of citations within a designated period of time. This prohibition shall not affect the conditions of any federal or State grants or funds awarded to the Illinois State Police and used to fund traffic enforcement programs.
The Illinois State Police may not, for purposes of evaluating an Illinois State Police officer's job performance, compare the number of citations issued by the Illinois State Police officer to the number of citations issued by any other Illinois State Police officer who has similar job duties. Nothing in this Section shall prohibit the Illinois State Police from evaluating an Illinois State Police officer based on the Illinois State Police officer's points of contact. For the purposes of this Section, "points of contact" means any quantifiable contact made in the furtherance of the Illinois State Police officer's duties, including, but not limited to, the number of traffic stops completed, arrests, written warnings, and crime prevention measures. Points of contact shall not include either the issuance of citations or the number of citations issued by an Illinois State Police officer.
