Those who think that Stone Park is one of the worst for traffic citations have definitely not been in Blue Island, IL. Blue Island, Calumet Park, and Alsip share the same dubious distinction where they are extremely aggressive in traffic enforcement. Like Calumet Park, they also have instant-on radar and will not hesitate to nail you with it. As far as vehicles are concerned, they have the normal cadre of Crown Vics but have an Explorer, an Expedition 4WD, and 2 Intrepids.

However, one of the coolest things about Blue Island is that they will nail trains on Western, 127th, and 139th if they are tying up traffic. The reason for this is that those areas are in close proximity to a hospital (St. Francis) and these trains have a history of blocking the streets for hours on end.

But that aggressive enforcement is not solely for trains. Automotive drivers really have to be wary because these guys have been known to make Stone Park and Elburn look like choir boys.

Areas you need to be careful in:

Western Avenue: There are a lot of lots that the cops can use to hide. There are also plenty of side streets that they can park lights out and nail motorists. In addition, they are known to do rolling patrols on Western quite often.
Pay attention between 119th and 127th which is where they are going to be heaviest. Also, I recall them pulling a "wolf pack" years ago on Western where they had at least 6 cop cars parked lights out in a 1 block radius (2 in McDonald’s, 2 in Bank lot, 2 right by the main bank entrance). At 127th, they will park in the Walgreens lot after hours.
South of 127th, watch out around the side streets, loading docks, junkyards, and even the trailer parks in the area. They have been known to hide in those areas.

119th and Vermont Streets: These two are lumped together because they have one common thing that the cops use to nail motorists. The cops like to hide in the Metra station lots on both streets. On Vermont, there are three lots that they will hide in. The worst is the one by the Metra Electric because they cannot be seen until it’s too late. Also, both have side streets where they will hide with alarming frequency.

127th: Watch out around the bridge between Winchester and Gregory/Vincennes. If BIPD isn’t bad enough, Cal Park will join them on occasion and make life even more miserable. From time to time, there will be cops radaring from the bottom of that bridge to nail speeding motorists. Also, watch in the Jewel and Walgreens lots around Western. After that, watch the two side streets around the railroad tracks. Cops are seen radaring over in those areas quite frequently. Also watch out around the Bowling Alley, Eisenhower High School, the Pace Kiss and Ride Lot, and the Nombach Roofing lot.

Wireton Road: After the road curves, there are several places where they can park and hide. One of the worst is shortly after the road curves. They try to get motorists who don’t slow down for the reduced 30 mph limit coming south on Wireton. But going north, there are several loading docks and lots that they use to stealthily radar motorists.
