The California Highway Patrol said Sunday that Pamela Bach was pulled over Saturday night just south of U.S. 101 on Laurel Canyon Boulevard. She was booked at the LAPD's Van Nuys jail and released.
The patrol says Bach showed blood alcohol levels of .14 and .13 on a breathalyzer test. California's legal limit is .08.
Bach was charged with misdemeanor hit-and-run in 2007, but the charges were dropped when she agreed to pay minor damages to the woman whose car she hit. She pleaded no contest to a drunken driving charge in August and was placed on three years of informal probation, court records show.
She was also ordered to go to a treatment program and not drive with any measurable amount of alcohol in her blood.
A phone message left for Bach's attorney, Ronald D. Hedding, was not immediately returned Monday. She is scheduled to appear in court on Dec. 24.
Bach was married to Hasselhoff for 16 years until he filed for divorce in 2006. She appeared as a cafe owner in several episodes of Hasselhoff's series, "Baywatch."
