Jessica Smith, a former cast member of MTV's "Laguna Beach: The Real Orange County," was arrested for investigation of felony driving under the influence of alcohol after a freeway crash, the California Highway Patrol said.
Smith, 19, crashed a 1999 Volkswagen Beetle into another car late Monday night on northbound Interstate 5 near Oso Parkway, a CHP report said.
The driver of the other car had minor injuries as did a passenger in the car driven by Smith, the report said.
She remained in custody in lieu of $100,000 bail. Her arraignment was scheduled Wednesday at the Harbor Justice Center.
The CHP doesn't release blood alcohol levels, according to spokesman Chris Goodwin.
