The California Highway Patrol closed Highway 41 from Harlan Avenue to Laguna Avenue for several hours after a flatbed semitruck slammed into a motorcycle, killing the rider.
Investigators said the motorcycle was stopped at the traffic light when the truck struck it from behind, dragging the motorcycle and driver into a field.
The driver of the semitruck who ran away from the scene on foot is now in custody, authorities said. He has a French passport.
The Lowes flatbed truck he was driving was stolen out of Los Angeles.
