Black Ice Blamed On Dozens Of Crashes In Chicago Metro Area

Freezing drizzle made for dangerous driving conditions, causing more than 50 crashes in numerous Chicago suburbs Wednesday morning. The entire metro area was put under a Winter Weather Advisory until 9 a.m., warning of a glaze of ice on roadways, parking lots and sidewalks during the morning rush hour. Dozens of crashes, jack-knifed semis and spin-outs were reported as many hit the roads early Wednesday morning. "Drive at slower speeds and be prepared for vehicles losing control around or ahead of you. Please do not go out on the roadways unless absolutely necessary," Illinois State Police said in a warning to drivers.
