Jessica Smith, 19, a cast member of "Laguna Beach: The Real Orange County," crashed a 1999 Volkswagen Beetle into another car late Monday night on northbound Interstate 5 near Oso Parkway, a CHP report said.
Contributing to the accident was speeding and a wet roadway, the CHP said.
The driver of the other car sustained minor injuries as did a passenger in the car driven by Smith, the report said.
The CHP does not release blood alcohol levels, according to spokesman Chris Goodwin.
Smith remained in custody in lieu of $100,000 (EUR74,923) bail. She was scheduled for an arraignment on Wednesday.
