Sgt. Jay Trisler says 23-year-old Brawley Nolte was driving north on Pacific Coast Highway Tuesday afternoon when he made a lane change and struck a vehicle in front of him.
Officers called to the scene believed Nolte had been driving while impaired. Trisler says Nolte was arrested following a series of sobriety tests. He was freed after posting $5,000 bail.
Trisler didn't know if Brawley Nolte had an attorney.
Brawley Nolte portrayed Mel Gibson's kidnapped son in the 1996 film "Ransom."
Nick Nolte pleaded no contest in 2002 to a misdemeanor charge of driving under the influence of drugs.
