SAN DIEGO — The San Diego Police Department’s (SDPD) Traffic Division will crack down on holiday drunken driving with a DUI checkpoint tonight, Dec. 17, from 9 p.m. to 4 a.m., according to a police statement. The location of the checkpoint has not yet been released, however. Downtown was the site of a November checkpoint and Pacific Beach was the site of a checkpoint on Friday Dec. 10, said Traffic Division Officer Mark McCullough. The Pacific Beach checkpoint involved 24 officers who arrested 16 suspected drunken drivers. Alcohol-impaired deaths account for the largest category of overall vehicle fatalities, despite traffic deaths having declined by 23 percent between 2007 and 2009 — from 3,995 fatalities to 3,081, according to the statement. Drivers who see a possible drunk driver are urged to call 9-1-1. The DUI checkpoint was funded by a grant from California Office of Traffic Safety. —Debbie Hatch
