California prosecutors have charged Heather Locklear whose TV credits include Dynasty and Melrose Place, with driving while under the influence of prescription drugs.
The California Highway Patrol said the actress showed "obvious impairment" when an officer noticed her car parked and blocking a lane on a highway in September, but that alcohol was ruled out. She was tested for drugs at a police station and released.
Locklear, who divorced Bon Jovi guitarist Richie Sambora last year, sought treatment for anxiety and depression in June.
Locklear is scheduled for arraignment on January 26. Her attorney, Blair Berk, did not immediately return an e-mail on Monday.
