Troopers say the crash involved a Colorado Department of Transportation (CDOT) snowplow, two passenger vehicles, and a sprinter van carrying a hockey team from California. According to the CSP crash investigation, the CDOT plow truck was traveling westbound on I-70 when the driver lost control, traveling through the median and breaking the cable rail into the eastbound lanes. The plow then collided with a Toyota Tacoma that was traveling eastbound. CDOT says the plow continued eastbound and struck the sprinter van that was traveling eastbound, which caused the van to go down an embankment and the plow to come to rest on the shoulder. The remaining occupants of the sprinter van included one adult male passenger who refused medical transportation, as well as the driver who was declared dead at the scene.
