he snow was falling hard, the visibility was poor and the road was undoubtedly slick as the trucks came barrelling down Interstate 80, one after another. Each of them tried to stop, but it was too late. A few of the drivers were able to slow down or veer onto the roadside, but most of the rigs slammed directly into the pile of already-wrecked semis blocking the highway.
This crash happened on the morning of April 16, 2015, about 15 miles west of Cheyenne, Wyoming. More than 45 vehicles were involved, and 27 people were injured, six of them seriously or critically, according to the Wyoming Department of Transportation. Nobody died.
Bystander videos posted online capture parts of the wreck as itunfolds.
As each truck crashes, the explosive sound of the impact mixes eerily with bursts of wind. There’s other footage that documents the aftermath: semi van trailers crumpled and sheared in half, truck cabs ripped from their chassis. A Toyota Prius partly crushed.
