Miles Danforth, 20, sustained major injuries that were not life-threatening as a result of the crash, said California Highway Patrol Officer Adam Garcia.
The crash occurred at about 7:30 a.m. Garcia said the location was on Highway 20 east of Rosemont Drive, just west of Lucerne.
Garcia said that Danforth, who was traveling eastbound in a 1994 Chrysler, swerved directly into the path of a Mitsubishi moving van driven by 56-year-old Boris Kuznetsov of Citrus Heights.
Danforth was flown to Santa Rosa Memorial Hospital, said Garcia. Kuznetsov escaped serious injury.
The air ambulance landed on the road shortly before 8 a.m., blocking the highway, according to CHP repots. Traffic was completely reopened at about 9:15 a.m.
Garcia said Danforth claimed fatigue as the reason he swerved into the opposite lane. Alcohol is not believed to be a factor.
CHP Officer Carl Thompson is leading the investigation, Garcia said.
