Lindsay Lohan was treated in hospital after rear-ending a truck in her Porsche, trashing the car but only causing minor injuries to the perennially troubled actress, police said. The 25-year-old spent two hours undergoing tests after the accident in which the car she was reportedly driving smashed into an 18-wheel big rig. There was no indication that Lohan was under the influence of alcohol or drugs. The truck driver was unhurt and not “impaired”-under the influence of alcohol or drugs. Pictures of the car showed its front end totally crushed, and the TMZ celebrity website said Lohan suffered bruises and bleeding in the crash. A publicist for Lohan said the actress was on her way to a movie set when the crash occurred, and she was taken to a hospital “as a precaution,” but was released in less than two hours and was “fine.” After leaving hospital she headed straight to the set of her latest film, a television movie about Hollywood legend Elizabeth Taylor and her stormy romance with actor Richard Burton.
