A woman was arrested on suspicion of drunken driving outside Gualala early Saturday morning after she rolled her car on a rural road.

The accident caused her passenger, a 29-year-old woman from Point Arena, to be flown to Santa Rosa Memorial Hospital with major injuries.

Nicole Garcia, 33, of Gualala was driving her 2004 Mazda south on Old Stage Road north of Gualala around 5:40 a.m. when she drifted off the road, lost control and the car rolled over, according to the California Highway Patrol.

Garcia was treated at Ukiah Valley Hospital for minor injuries and was arrested on suspicion of felony DUI.

CHP officials declined to release the name of the passenger.
