Colorado State Patrol is investigating a two-vehicle head-on crash that happened 11 miles west of Pueblo on Highway 50. Troopers say one person was seriously injured.

A Chevy Malibu driven by a 16-year-old male driver was traveling westbound on Highway 50 when a 1997 Chevy Blazer driven by 34-year-old Bryson Wiler of Pueblo was traveling eastbound. At Swallows Road the Malibu crossed the center-line and struck the Blazer head-on.

The Malibu rolled several times and three passengers inside were taken to the hospital with injuries.

Alcohol is not believed to be a contributing factor in the crash.
