The big rig was traveling on the 5 Freeway in Sacramento when it slammed into the back of a dark-sedan. That set off a chain reaction involving more than six vehicles as it continued to barrel down the freeway at a forceful speed.
The oversized big rig eventually tipped over and blocked all of the southbound lanes.
One person was killed in the pile-up and two others suffered only minor injuries. Officials don't believe drugs or alcohol were a factor in the crash.
