About 30 drivers in Pennsylvania who zipped by a construction worker while over the speed limit got a rude surprise less than a mile down the road. That construction worker was actually a state trooper in disguise, and he then radioed ahead for the speeders to be pulled over on Wednesday, reports TribLIVE. Troopers teamed up with the state's transportation department on the ruse, in which a trooper dressed up as a construction worker and sat in a PennDOT truck with a radar gun on busy Route 66 in Washington Township. The trick is actually an old one, at least in Pennsylvania, notes WBRE. (More weird crimes stories.)
