The 18 days of heightened drunken-driving enforcement by county police departments, the Sonoma County Sheriff’s Dept. and the California Highway Patrol resulted in 169 DUI arrests throughout the county.

 The extended enforcement period began Aug. 17 and ended at midnight on Monday, Sept. 3. Fortunately, there were no fatalities because of drunken drivers, but there were eight crashes because of drunken drivers. Ten people were injured in those crashes, according to Petaluma Sgt. Ken Savano, who spearheaded the campaign.

Savano said 45 of the 169 arrests came during the three-day holiday weekend. Law enforcement officials also arrested 35 people wanted for drunken-driving warrants and five were busted for violations stemming from DUI convictions.

There were three DUI checkpoints set up in Santa Rosa and Cotati, and four of the drunken drivers were caught in those operations. Last year, there were 175 arrested for DUI.
