Any construction zone
Schaumburg is using new tricks to catch any speeders in their town in construction zones. One police officer, dressed as a construction worker, will be standing in the construction zone. He is armed with a radar gun. He then radios any information about speeding vehicles to an officer waiting down the road. You will, most likely, never see the officer with the radar as he is dressed in blue jeans and the usual orange construction vest. Very tricky. An article about this was even published in the Daily Herald newspaper just a couple of weeks ago.
