Law enforcement agencies in San Luis Obispo County will have increased patrols on the roads over the St. Patrick’s Day weekend to catch drunk drivers.

The county’s DUI Task Force will be deploying roving patrols in several communities throughout the county looking for impaired drivers over the weekend. The patrols will be looking for tell-tale signs of drivers that are impaired, said San Luis Obispo Police Chief Stephen Gesell.

“Today, we are giving fair warning to everyone traveling through San Luis Obispo County that our law enforcement officers will be out on patrol and if you are caught driving drunk, you will be arrested,” he said.

Federal traffic safety officials report that more than 700 people were killed nationwide by drunk drivers during St. Patrick’s Day holidays from 2006 to 2010. Most drunk-driving fatalities involve drivers that have blood alcohol levels more than twice the legal limit.
