Police said Lohan was driving her black Porsche with an unidentified male passenger on the Pacific Coast Highway in Santa Monica on her way to the set of her latest movie project, and collided with a dump truck.
The actress and her passenger were taken to the hospital as a precaution, and released shortly after. Neither Lohan or the driver of the truck were under the influence of drugs or alcohol, police said.
"Lindsay was involved in an automobile accident today on her way to the set....She is fine and was released less than two hours later and is already headed back to the set to resume work. Fortunately, no one was seriously injured in the accident," Lohan's publicist, Steve Honig, said in a statement.
Celebrity news website TMZ posted pictures of Lohan's Porsche following the incident, showing a crushed front and smashed windows.
Lohan, 26, is forging ahead with a comeback after a string of legal and personal troubles since 2007, including stints in jail, rehab and court. She was released in March from almost five years of formal probation stemming from a 2007 drunken driving and cocaine possession arrest.
The actress is currently playing late screen legend Elizabeth Taylor for a Lifetime TV movie "Liz & Dick," based on Taylor's love affair with actor Richard Burton.
