Rodney King has been sentenced to 20 days of house arrest and fined $500 for misdemeanor reckless driving in Southern California.
King is the black motorist whose beating by white Los Angeles police officers was videotaped in 1991. Four officers were acquitted of charges in state court a year later, leading to rioting in Los Angeles.
The 46-year-old King was arrested in Moreno Valley seven months ago for investigation of drunken driving.
But Riverside County prosecutors say his blood-alcohol reading was 0.06 percent, which is below the 0.08 legal threshold. He also had a trace of marijuana in his system.
The Riverside Press-Enterprise says King, through his attorney, pleaded to a lesser so-called "wet reckless" driving charge on Monday.
King also was placed on three years' probation.
