Watch out for CPD traffic units sitting at either of the above. The way to distinguish them is by looking at the light bar (Federal Signal Vision versus Whelen Edge or Federal Jet Strobe) and the beat card placed on the light bar (Usually begins with a 32 (Chicago only has 25 districts)). The key points on Lake Shore Drive are near Sheridan Road, Near Fullerton, near Soldier Field/Museum Campus, near McCormick Place, and Near the Field Museum of Science and Industry. The speed limit on Lake Shore Drive is 45 mph (some spots 40, and 35 around Soldier Field). These cops will sit around 63rd, 53rd, 47th, in the median between 47th and 23rd, on the side around Soldier Field, around Lake Point Tower and the Gold Coast, and in different locations between Fullerton and Sheridan.
