A couple of things. First of all, these troopers in District 15 (Tollway) are rather aggressive in speed enforcement. They tend to use the same motto as Malcom X – By ANY means necessary.

First of all, you have troopers in unmarked cars. Quite literally, I have seen Camaro Z28s, Mustang GTs, Grand Prix GTPs, a Suburban, and the regular cadre of unmarked Crown Vics and Impalas nailing people. However, the ones in the unmarked cars are the ones you have to watch out for. These contain a trooper who is known to have high "activity." Translation: A very aggressive ticket writing trooper. Some of these cars have front and rear firing radar (Primarily the Mustangs and Camaros).

Sometimes, these guys will sit on ramps or near bridge abutments to nail speeders. I have also seen them sit at the end of I-Pass lanes to nail motorists who don’t observe the 30 mph limit or do not have an I-Pass. The areas to really watch out for are between the 22nd Street cashbox and 127th St. A lot of that road is very curvy and they use that to their advantage. Also, they will be sitting near the Hinsdale Oasis (Be especially careful if you see a Navy Blue Z28 around there as it is one of the LS-1 powered versions). After I-55, they will sit near abutments, and on the ramp from LaGrange. Then if the troopers aren’t enough to worry about, then you have the Cook County Sheriff’s Police. They will use many of the same tricks as the troopers and are just as aggressive.
