The sheriff's department in Illinois with the most DUI arrests in 2013 is Lake County, with 348, the Alliance Against Intoxicated Motorists reported Tuesday in its 24th annual survey. The Cook County Sheriff's Department came in second in the state with 306; Winnebago County had 295; Will County had 262 and DuPage County rounds out the top five with 245. Since 1990, AAIM has surveyed Illinois police departments to recognize the most productive departments and police officers in the fight against drunken drivers. For the seventh year, the Rockford Police Department is first in the state in DUI arrests among municipal departments with 556 arrests. (Because of its size, Chicago is in its own category.) Naperville was second with 553 arrests, followed by Decatur, Springfield, Carol Stream, Elmhurst, Normal, Rock Island, Oak Lawn and Aurora rounding out the top 10.
