San Diego's regionwide seasonal crackdown on tipsy, drunken and drugged driving begins tonight! San Diego County Sheriff's Department will have a special priority in its anti-Drunk Driving strategies: impaired driving among young folks.

From Friday through Jan. 3, law enforcement agencies across the San Diego area and throughout California plan to run frequent sobriety checkpoints to keep the streets as safe as possible amid end-of-year festivities, according to the state Office of Traffic Safety.

"DUI checkpoints are time-tested and proven as the most effective DUI countermeasure, and I'm gratified that we're seeing the life-saving results," said OTS Director Christopher Murphy.

The stepped-up San Diego DUI enforcement, which will include extra patrols to nab inebriated motorists, is funded by state grants to individual law enforcement agencies.
