Robert James Feenan, 50, was arrested Nov. 20 after his vehicle collided with another vehicle on state Highway 12 and Stony Point Road, the Sonoma County District Attorney's Office said.
The California Highway Patrol responded to the crash and Feenan had a blood-alcohol level of 0.44 percent, more than five times the intoxication level, the district attorney's office said.
Feenan pleaded no contest on Dec. 17 to DUI and driving on a license that was suspended for DUI.
On June 12, 2008, when he was arrested for his previous DUI, his blood-alcohol level was 0.22 percent, the district attorney's office said.
He pleaded no contest on June 19, 2008, to that DUI and admitted he had seven previous felony DUI convictions and had recently been to prison, the district attorney's office said.
On Aug. 20, 2008, Feenan was sentenced to probation, a year in the county jail and ordered to under go treatment, the district attorney's office said.
The Sonoma County District Attorney's Office asked the court to sentence Feenan to the maximum term of four years in prison instead.
Feenan completed residential treatment for alcohol addiction on June 2, 2009, about five months before his November, 2009 arrest, the district attorney's office said.
The 2009 arrest also was a violation of his probation, the district attorney's office said.
"We will continue to object to these individuals being given sentences that threaten public safety and applaud the court for giving him the maximum sentence for this egregious conduct," Assistant District Attorney Diana Gomez said.
