The driver of the truck had no idea he was taking a family of four along for a ride.

Michigan family Matthew and Pamela Menz and their two adult children were driving down Interstate-75 during a white out when Matthew hit the rear and of a semi-truck, trapping them underneath.

As Pamela tells the 911 operator, they had lost any ability to honk their horn, so the driver of the truck continued along, completely unaware he was dragging the family with him. Having lost power and heat, Matthew told 911, "Our windshield is completely shattered. I can't see nothing. I don't have any control of the thing."
