 The driver of a 99 GMC pickup truck was traveling the same direction behind the semi. As the driver of the semi initiated a right turn onto 475th Avenue, the driver of the pickup swerved to the left and struck the semi trailer. The driver of the semi was not injured. The driver of the pickup had minor injuries and the passengers sustained fatal injuries from the collision. Alcohol does not appear to be a factor in the crash. Seatbelts were not worn by either the driver or the passenger.
