A Lompoc woman died in a single-vehicle collision sometime Wednesday night or Thursday morning when she overturned on Santa Rosa Road.
Alcohol is considered a factor in the crash, according to the California Highway Patrol.
The Santa Barbara County Coroner’s Office is conducting a routine toxicology report to confirm the level of impairment.
The woman, who has not been identified by authorities, was driving on Santa Rosa Road near Highway 1 when she apparently drifted off the side of the roadway and over-corrected, then hitting an embankment, CHP said.
The 24-year-old woman was found dead and partially ejected from her vehicle, a 2003 Volkswagen Beetle.
CHP Sgt. Donald Clotworthy said she was not wearing a seat belt, and there were no passengers in the car.
The collision happened between 11 p.m. Wednesday and 6 a.m. Thursday. Anyone with information about the collision is asked to call the Buellton CHP at 805.688.5551.
