A 29-year-old Shandon woman was killed early Monday morning in Atascadero after reportedly driving her vehicle off Highway 101 and onto a dirt embankment, striking a freeway exit sign and an oak tree.
The California Highway Patrol says the woman, who has yet to be identified pending notification of family, was pronounced dead at the scene.
At about 4:35 a.m., the woman was driving north on Highway 101 just south of San Diego Way when, for reasons unknown, she traveled off the east side of the road and onto an ascending dirt embankment, according to a CHP news release. She tried to steer the vehicle, a 1991 Toyota Camry, back onto the highway but apparently over-corrected and lost control of the vehicle.
The car then veered off the east side of the road again, where it became airborne and struck a freeway exit sign and an oak tree.
The woman was not wearing a seat belt and was partially ejected from the vehicle.
The investigation remains ongoing, but the CHP says drug or alcohol impairment has not been ruled out in the crash.
