There, authorities say the driver of a Pontiac minivan was traveling at a high rate of speed eastbound on the highway and passed several vehicles before running into a Chevy truck that was towing a trailer. The collision sent both vehicles to the left over the westbound lane of travel and into the north ditch. Upon entering the ditch, the minivan tripped and rolled onto the passenger side.
