A semi-truck driver has died after suffering a medical condition along U.S. 36 on Monday, according to the Colorado State Patrol.

CSP says the driver pulled off the highway near McCaslin Blvd in Superior. That's when that driver suffered some sort of medical episode, causing the truck to jackknife.

The driver has died, CSP says likely due to that medical condition.

There was also another crash just after where the semi-truck jackknifed. CSP says no one was injured in that accident.
