Video Of Massive Pileup On Snowy Road Serves As Warning For Chicago Drivers

CHICAGO (CBS) -- The Chicago area is expected to get 2 to 4 inches of snow during the morning rush hour on Wednesday.

The video with this story shows a massive pileup on a Wisconsin highway on Sunday--in similar conditions that are expected here tomorrow morning.

So, on Wednesday morning, slow down.

And if you need proof, watch this video.

It gets particularly scary around the 3:20 mark.

Nobody was killed in this accident, but three others died in separate accidents across the area.

The footage shows a massive pileup--police say dozens of cars and trucks were involved--as one vehicle after another slides out of control during the five-minute clip.

Drivers exiting their cars are seen scrambling to avoid being hit by out-of-control automobiles.

The accident happened on Highway 41/45 near Lannon Road in Germantown, Wis.

In a separate pileup accident a few miles down the same highway, police in Menomonee Falls said two people were killed.

The third fatality involved a woman who was killed in a rollover accident on Interstate 43 in Milwaukee County, police said.

Sunday's crashes shut down the highway for about nine hours.
