Actress Lindsay Lohan was hospitalized briefly after a car crash at about 11:45 a.m. Friday near the California Incline on Pacific Coast Highway in Santa Monica.
Lohan was in a black Porsche that slammed into an 18-wheel dump truck while en route to the set of her latest film, Liz & Dick, in which she is portraying screen legend Elizabeth Taylor.
Neither Lohan or a second occupant in the Porsche were under the influence, said Santa Monica Police Sgt. Richard Lewis. He said investigators have not determined if she was the driver.
A spokesman for Lohan released a statement saying she was "fine" and hospitalized for about two hours as a precaution. After being released, Lohan headed directly to the set of the new Lifetime movie, the spokesman said.
"A preliminary investigation revealed that both vehicles were driving northbound on Pacific Coast Highway when the Porsche struck the rear end of the dump truck," Lewis said. "[The] cause of the accident is under investigation."
TMZ reported the Porsche was totaled, with the passenger window shattered and the bumper fully off the car.
Several entertainment websites reported Lohan's assistant was in the Porsche with the actress at the time.
The 25-year-old actress was convicted of drunken driving in a 2007 crash in Beverly Hills. Her probation ended March 29, with Los Angeles Superior Court Judge Stephanie Sautner praising her completion of the terms of her probation.
She will, however, remain on probation through May 2014 on a case stemming from the theft of a necklace from a Venice jewelry store, but a judge has reduced that to unsupervised, summary probation.
