Officers have launched a multi-agency DUI and underage drinking patrol for the Halloween weekend.
Seven agencies in San Diego received nearly $2 million in grant to combat drunk driving throughout the next year.
The funding begins just in time for the Halloween weekend, which helps get more officers on the streets to reduce alcohol-related problems.
"We are taking a zero-tolerance approach toward driving under the influence," said Lawrence McKinney, San Diego Police Department assistant chief. "One life lost through DUI is too many."
Police will also be enforcing the house party law, which holds hosts responsible for underage drinking on their property. The San Diego State University area accounted for 86 percent of the citations issued during last year’s operation, according to the National Highway Traffic Safety Administration.
Last year, officers arrested nearly 300 people for alcohol-related charges the weekend prior to Halloween.
