I caught this article the other day in my local paper.
State agency checks truck emissions on North Shore - SILive.com
There was a picture of them doing a smoke test, and they were driving a very unofficial looking Crown-Vic. The day before this story was printed, I actually saw them driving around and was thinking about what they were looking for. As it turns out, they're looking for soot buildup anywhere near the exhaust.
