Los Angeles fire spokesman Erik Scott says five people were hospitalized early Saturday, but none of the injuries are considered life-threatening.
Police Sgt. O.C. Smith says the town car driver thought he had shifted into reverse when he accelerated. Smith says the limo slammed into the car, knocking it off the elevated parking lot in the Hollywood Hills.
Both vehicles fell onto the courtyard of an adjacent apartment building. The building was not damaged.
The wreck remains under investigation.
