[12][13] Illinois State Police currently use various methods for speed limit enforcement on Illinois highways, including hand-held and moving radar, LIDAR, pacing, air speed utilizing the ISP fleet of aircraft, and VASCAR.

Routine calls for service include, but are not limited to, missing persons searches, criminal manhunts, surveillance, pursuits, photo/video needs, civil unrest, patrol support, and transportation.

The board consists of five civilian members appointed by the governor with the advice and consent of the State Senate.

Instead of a chocolate brown uniform worn by the Iowa State Patrol, or a light blue on dark blue uniform worn by the Missouri State Highway Patrol, ISP officers wear light tan/khaki shirts, and dark green pants with black trim.

Leather duty gear consists of black high gloss clarino holsters, belts, and accessories.

ISP officers wear a dark brown campaign hat called a Montana Peak.
