Tinley Park is a somewhat affluent suburb but they get their share of revenue from traffic citations. The main points to watch for Tinley’s finest are 159th, Harlem, 167th, 175th, and 183rd. 159th is littered with strip malls, restaurants, banks, and churches. These guys are liable to sit in any of them and clock you. 167th west of Harlem is also notorious because the speed limit drastically drops from 40 to 25 since it turns residential. 183rd is also nasty as there are a lot of places for them to hide (e.g. the Burger King on 183rd and Harlem). Finally, the cops are on constant rolling patrol on Harlem as well as Oak Park Avenue and Ridgeland.
