DIAMOND BAR >> A person has been hospitalized in unknown condition after being struck by a truck on the 60 Freeway in Diamond Bar early Saturday.
The incident occurred on the westbound lanes of the 60 beneath the 57 Freeway about 2:45 a.m., California Highway Patrol Officer Tony Polizzi said.
The sequence was initiated with a single-vehicle crash with either the center divider or the right shoulder wall of the freeway, causing the vehicle, a gray Cadillac, to catch fire, according to CHP logs.
The Cadillac appeared to have had two occupants, according to Los Angeles County Fire Department officials and a videographer at the scene.
At least one of them exited the car, officials said.
A person, described only as male, was trying to put out the fire when he was struck by a truck, Los Angeles County Fire Department Dispatch Supervisor Al Jackson said.
Another driver stopped and dragged the victim out of the freeway lanes, according to the log.
Paramedics took the injured person to the University of California, Irvine Medical Center for treatment, according to fire and CHP officials. An update on his condition was not available.
The second person inside the Cadillac was not hospitalized, officials said.
Fire officials described the involved truck as a big rig, while CHP officials described it as a delivery truck.
The investigation was being handled by officers from the Baldwin Park office of the CHP, who could not be reached for comment.
