For reasons still to be determined, the driver of an 18-wheel commercial vehicle that was traveling south on the highway, approaching the intersection of Jack’s Valley Road, failed to stop safely for stopped traffic. There were six other southbound vehicles stopped or almost stopped for the red traffic signal light at that intersection. Those vehicles included a green Honda Civic two-door, a green Ford Explorer SUV, a gold BMW X5 SUV, a black Chevrolet van, a white International dump truck and a silver Buick four-door sedan.
The driver of the 18-wheeler applied the brakes and slammed into the green Honda and the green Explorer. The Explorer was forced into the adjacent white dump truck and also struck the black Chevrolet van, while the Honda struck the back of the BMW. The Chevrolet van then struck the rear of the silver Buick. There were two women and a young man riding in the Explorer. They had to be extricated from their SUV by fire department personnel. The two women were airlifted to Renown Regional Medical Center for injuries believed to be critical, while the young man was transported to a local hospital. The driver of the green Honda was airlifted in a second Care Flight helicopter and also flown to Renown for injuries believed to be serious. The only other reported injury was the female passenger riding in the silver Buick. In total, 11 motorists and seven vehicles were involved.
