Illinois State Police District 15 is already one of the most aggressive districts in terms of enforcement. But on this stretch of 294, this is one of the busiest in terms of enforcement. When it gets close to a holiday, it is not uncommon to see at least 10 or more stopped cars in that stretch.

In terms of the unmarked cars, besides the usual Crown Vics and Impala, I have seen vehicles such as Grand Prix GTPs, Mustang GTs, Z28s, 1 WS-6, the infamous Caravan, a Suburban, and even a LeSabre. All of the forementioned vehicles do not have any type of distinguising markings, thus making them harder to spot in traffic. But some of these cars have dual firing radar.

As far as locations are concerned, watch any of the on/off ramps leading to the O’Hare, Hinsdale, and Lincoln Oases. Also, be especially careful between the Hinsdale Oasis and the 82nd Street Toll. I have seen them hide in the following locations:

a) Shoulder near Hinsdale Oasis:
I have seen a Blue LS-1 powered Z28 around there from time to time. I have also seen the GTPs on rolling patrol between I-55 and the Hinsdale Oasis. They will use the curves and bridge abutments to their advantage

On Ramp from LaGrange Road to S/B 294:
I have seen marked State Police and County Sheriff units radaring folks from that point.

75th Street On Ramp/Off Ramp:
Troopers will sit there and radar traffic

82nd Street and 22nd Street Toll Plazas:
They will sit at the end of the I-Pass lanes or on the side.
Their main goals in those areas are to nab speeders and folks who do not have an I-Pass blowing through the I-Pass lanes. I have also seen marked and unmarked cars in the toll employee parking lots waiting to nab motorists.

95th to 127th:
Watch the ramps at both locations. In addition, the road in that area is quite curvy and the cops use that to their advantage. There are a couple of turnaround lanes in that stretch.

135th to I-80:
Ramps, turnaround lanes, and the 163rd St. Toll Plaza. They will also use bridge abutments to hide.
