A video cam caught an amazing forty car pile up on an ice covered Interstate near Germantown, Wisconsin. No one was killed and twelve had injuries. For five minutes as you watch this tape, you are waiting for the next car or truck to hit. Just as you think it will let up more crash.
The lesson is don't travel on icy roads unless it is an emergency. Even those who were able to safely bring their cars to a halt got hit because of less safe drivers.
