Actress Mischa Barton, who starred on the television drama The OC, was sentenced to three years probation and ordered into an alcohol education program after she pleaded no contest to drunken driving.
As part of the plea deal, which spared the London-born actress any jail time, prosecutors agreed to dismiss a marijuana possession charge and reduced a charge of driving without a license to an infraction, a court official said.
Barton, 22, was not present for the proceedings in a Beverly Hills court. Her lawyer entered her no contest plea, the functional equivalent of pleading guilty in California, on her behalf.
In addition to probation, she was ordered to complete a three-month alcohol education program and was fined about $US2,000 ($A2,154), a Los Angeles County court official said.
The case stems from the December 27 arrest of Barton, best known for her role as Marissa Cooper on Fox network's The OC, who police said was weaving between two lanes of traffic and failing to signal a turn while driving in West Hollywood, a community in the Los Angeles area.
Barton spent about seven hours in jail before being released on $US10,000 ($A10,773) bond.
Appearing the following month on a Los Angeles radio talk show, Barton made a public mea culpa for her behavior, saying she was "100 per cent responsible for my actions in this case," according to People.com.
