The Chicago Police Department is turning up the heat on impaired driving this weekend in the 15th (Austin) District. From Saturday to the early hours of Sunday, officers will scour the streets in a concentrated effort to curtail DUI incidents – an initiative known as DUI Saturation Patrol. For those planning on a night out in Austin, expect an increase in police presence and traffic enforcement from 6:00 p.m. to 2:00 a.m.
