The California Highway Patrol has identified the woman killed in a rollover crash on Adelaida Road on Monday as Laura Nolasco de Hernandez, 56, of Paso Robles.
The crash happened at about 2:40 p.m., west of Hidden Mountain Road.
According to the CHP, Nolasco was driving westbound in a 1999 Acura CL when, for unknown reasons, she crossed into the eastbound lane and went off the side of the road. Her car overturned several times down a 65-foot embankment.
Nolasco was wearing her seatbelt but died as a result of the crash. There were no other occupants in the vehicle.
The CHP says alcohol and/or drugs are not suspected to be a factor in this crash.
Adeladia Road was closed for several hours between Hidden Mountain Road and Stag's Leap Way while emergency officials were on scene and crews worked to remove the wrecked vehicle.
