Ohio uses this too. Altho it's not usually helicopters, but small two-person planes. It's not used often, but they'll selectively use (on heavy travel days, like thanksgiving). Or they'll target a certian area for a week or so that's been having a lot of accidents or chronic speeders. Obviously, it's really only used on highways. So it kinda makes sense that it's the State Highway Patrol that usually heads to the skies. Some states/areas have thier own aircraft, if not they just contract a pilot and craft.

Funniest story I know about said technique is the guy that got targeted by the plane and the patrolman on the ground flagged him over. The driver began ranting that he was only pulled over because he was a minority and that this was descrimination; as if they could see what he looked like from the plane!

(Hint: When driving down the highway and you start to notice a series of white lines running across the road perpendicular to you, slow down. they have to time you from 2-3 different benchmarks before they can pull you over).
