In its Wednesday report, the California Highway Patrol’s Clear Lake Area office did not release the name and age of the woman who died in the wreck pending notification of her next of kin.
The CHP said the solo-vehicle crash occurred at 8:15 p.m. Tuesday on Highway 20 near Walker Ridge Road, east of Clearlake Oaks.
The woman was driving a 1999 Toyota 4Runner westbound on Highway 20 just east of milepost marker 38.35 at an unknown speed when the wreck occurred, the CHP said.
Riding as the passenger in the vehicle was 20-year-old Isabella Rosario Moon of Chico, according to the CHP report.
For reasons that the CHP said are so far unknown, the driver allowed the Toyota to veer to the right side of the road and onto the dirt shoulder.
The CHP said the driver overcorrected and steered the Toyota back to the left where the vehicle overturned in the middle of the roadway, sliding off the south side of Highway 20 and down a dirt embankment.
As the Toyota was going over the embankment, the driver – who the CHP said was not wearing her seatbelt – was ejected from the vehicle. Radio reports indicated that firefighters and CHP officers who arrived at the scene found her unresponsive. The CHP said she died of her injuries at the scene.
The CHP said that Moon, who was wearing her seatbelt, sustained minor to moderate injuries.
Firefighters transported her to Adventist Health Clear Lake Hospital, where the REACH 6 air ambulance picked her up and transported her to Santa Rosa Memorial Hospital, officials reported.
It is unknown at this time if alcohol or drugs are contributing factors to the collision, the CHP said.
