Police say the man stopped his pickup truck behind the car and had gotten out with his passenger when the semitrailer drifted over, hitting the truck, the two men and a passenger from the car. The pickup truck driver was killed instantly, while the other two men hit were taken to hospitals with non-life threatening injuries.
