The Taft woman killed in a single-vehicle accident north of Taft early Sunday was not wearing a seatbelt and was ejected when the Jeep Cherokee she was driving overturned, the California Highway Patrol said in a news release.
A passenger was also ejected but survived.
Jamie Renee Tweedy, 23, was pronounced dead at the scene of the 12:15 a.m. crash off Elk Hills Road south of the California Aqueduct near Buttownwillow, the CHP and Kern County Coroner said.
Her passenger, Tevis Stephens, 24, who lives in Buttonwillow, the CHP said, was not wearing a seatbelt either and was also thrown from the Jeep.
His injuries were described as moderate by the CHP.
He was flown to Kern Medical Center by air ambulance.
The CHP said the crash happened when Tweedy's jeep drifted off the roadway and she lost control.
She was driving north on Elk Hills road just north of Skyline Road.
Alcohol or drugs is not believed to be a factor in the crash.
The investigation is continuing.
