A Ukiah woman was arrested on suspicion of driving under the influence early Thursday after she crashed her car into a tree on Highway 20 west of Witter Springs Road.

Leona Maria Delapena, 29, was driving her 2008 Honda Accord east on Highway 20 with two passengers at about 1:40 a.m. when the car veered off the road's south shoulder and slammed into a tree, CHP officials said.

Delapena, who was arrested, received moderate injuries and was transported to Sutter Lakeside Hospital. Jason Steele, 21, of Ukiah, a passenger, also suffered moderate injuries and was transported to Ukiah Valley Medical Center.

Another passenger, a 17-year-old Ukiah resident whose name was not released because she is a minor, was transported to Santa Rosa Memorial Hospital.

All three were wearing seat belts at the time of the crash.
