They do them all the time in IL.
About 5 years ago, I was pulled over in one. The rookie state trooper (on a city street) gave me a field sobriety test and quickly determined I was not drunk. He then proceeded to measure bumper height, check headlights, turn signals, horn, etc. It wasn't until he decided to check the side windows (they were tinted) that he found something to write me a ticket for.
