Kimberlee Annette Westbay, 52, died in the crash, according to Capt. James Bauman of the Lake County Sheriff's Office.
The collision occurred just after 10:30 a.m. Friday on Highway 20 at Scotts Valley Road near Blue Lakes, officials reported.
Anton Timothy Kloiber, 34, of Piercy was driving a black 2008 Chevy Tahoe westbound on Highway 20 when he is alleged to have allowed his vehicle to travel into the oncoming lane in front of Westbay's black 1990 Nissan pickup, according to the CHP report.
The two vehicles collided, with Westbay's Nissan spinning off the roadway, the CHP said.
The CHP said Kloiber's Tahoe continued westbound, hitting the left rear of a red Ford F-150 pickup driven by 48-year-old Dale Box of Upper Lake.
Westbay was pronounced dead at the scene, the CHP said, with Kloiber complaining of minor pain and Box sustaining no injuries, the CHP said.
The CHP arrested Kloiber shortly after 11:30 a.m. on suspicion of driving under the influence of alcohol or drugs, according to the report.
He was booked into the Lake County Jail just after 7:30 p.m. Friday on felony charges of gross vehicular manslaughter while intoxicated and driving under the influence of alcohol or drugs causing bodily injury. Bail was set at $150,000.
Kloiber later posted bail and was released. He had been scheduled to be in court on Monday.
Bauman said an autopsy was performed Monday morning on Westbay, with the cause of the crash pending further investigation by the CHP. Officer Greg Buchholz is the case's investigative officer.
