40-vehicle pileup caught on camera during Wisconsin snowstorm

There's really no better way to demonstrate why you should slow down during a snowstorm than this.

A traffic camera from the Wisconsin Department of Transportation captured the scene on Sunday, Dec. 8, 2013, as car after car driving too fast for conditions slid and crashed during a snowstorm on Highway 41-45 near Lannon Road in Washington County. About 40 vehicles wound up being involved in the crash, though thankfully no one was seriously injured.
