Dash-cam – Amazing video of how dangerous highways become during snowy blizzards. In this incident a trooper is about to get out of his car to help a woman who was stranded on the highway when an out of control 18-wheeler truck is sliding on the snowy and icy highway. The truck jack-knifes and crashes into the patrol car. Inside the patrol car is another motorist who has already been rescued from his car. Fortunately, no one was seriously hurt.
