"The Chicago Police Department will conduct a DUI Strike Force Patrol along Lake Shore Drive this upcoming weekend. The DUI Strike Force Patrol will commence at 8:00 p.m. on Saturday, March 1, 2014 and end at 4:00 a.m. on Sunday, March 2, 2014.
The purpose of this program is to saturate a pre-designated area with roving police officers that continually monitor vehicular traffic for signs of impaired driving. Patrols also place emphasis on speed, alcohol-related and safety belt violations. Police vehicles equipped for speed detection are deployed to apprehend speeding violators.
In addition, the Breath Alcohol Testing (BAT) Mobile Unit may also be deployed to allow officers to expedite the process of charging a person with Driving under the Influence (DUI) prior to transporting an alleged into the nearest lockup for bonding. The mobile unit also allows for Individual Recognizance Bonds (I-Bonds) to be issued at the site of the DUI Strike Force Patrol."
When one of these things happens, they find all sorts of violations: unsafe cars, weapons in vehicles, lack of insurance, open containers, expired licenses and license plates. Don't give them a reason to pull you over and you won't have to deal with the unpleasantness.
