Two big rigs were involved in the initial crash at about 3:30 a.m. A driver suffered minor injuries.
"One driver possibly fell asleep and ran into the other big rig," said California Highway Patrol Sgt. Robert Rosenfelt.
A second crash occurred when a vehicle stopped for the first crash was struck by another driver. No injuries were reported in the second crash.
