The crash was reported to the California Highway Patrol at 4:16 a.m. on the westbound San Bernardino Freeway just east of the Orange (57) Freeway.
A witness told the CHP the big rig hydroplaned after the crash and hit the center divider with wreckage across all westbound lanes.
The CHP issued a SigAlert at 4:23 a.m. shutting down all westbound lanes of the San Bernardino Freeway. The transition to the Orange Freeway remained open.
It was not clear whether anyone was injured, CHP Officer M. Curtiss told City News Service.
