The California Highway Patrol announced today that the state recorded a decline in deaths due to drunken driving this past year for the fourth year in a row.

The CHP said the announcement follow's this past month's end of its yearlong DUI enforcement campaign.

"DUI has always been a huge safety concern for the law enforcement community and the motoring public," CHP Commissioner Joe Farrow said. "Impaired driving is a dangerous and irresponsible behavior that results in hundreds of victims killed and thousands of others injured every year in California."

The CHP said in October 2009, through the federally-funded Border-to-Border DUI enforcement campaign, officers assisted in reducing the number of alcohol-related fatal and injury crashes through the state.

They said the CHP conducted nearly 240 sobriety and driver's license checkpoint, 100 DUI task force operations and more than 50,000 hours of enforcement patrol. The campaign resulted in more than 1,900 arrests made, the CHP said.
