MONTEREY COUNTY, Calif. - A holiday crackdown on drunken drivers ended with 153 DUI arrests and one possible fatality in Monterey County, CHP officials said Friday.

The number of arrests during the 21-day holiday DUI crackdown, called “Avoid the 18,” was up 82 percent from last year, officials said in a news release.

The beefed-up DUI enforcement included more checkpoints, in-city DUI patrols and an emphasis on DUI enforcement with officers on regular beats.

A fatality that took place Dec. 26 is being investigated as a DUI crash, said Zoltan Treiner, of the CHP King City area command. No persons died in a DUI crash during last year’s campaign.

The holiday campaign was named for the 18 law enforcement agencies in Monterey County that are funded by the California Office of Traffic Safety through the Traffic Safety Administration.
