The Silverado became disabled on the road and an eastbound Chevy Silverado hit the Silverado.

The 16-year-old driver and their 17-year-old passenger were airlifted to the hospital. The sheriff’s office said they are in critical condition. Their names have not been released due to their ages.

A passenger in the van was also taken to the hospital with minor injuries.

It’s unknown if alcohol or drugs were a factor in the crash, the sheriff’s office said.
