Hilton was stopped Feb. 12 after a witness reported seeing a black Mercedes-Benz weaving on Pacific Coast Highway, the Los Angeles County Sheriff's Department said. He was allegedly carrying a fake driver's license.
Hilton was booked at the Malibu station and registered a blood-alcohol level of 0.14 percent - .08 is the rate at which a driver is legally intoxicated in California.
Hilton was freed on $20,000 bond and is scheduled to be arraigned April 14.
Last year Paris Hilton, the 26-year-old reality TV star and hotel heiress, pleaded no contest to alcohol-related reckless driving and was sentenced to 45 days in jail. She served a little more than two weeks.
