Exactly what led up to the crash is unclear, but a pickup truck and a big rig were involved. The big rig flipped onto its side after the crash and the driver suffered minor injuries, California Highway Patrol says; the other driver wasn’t injured.

One lane of westbound I-80 is closed due to the incident. The lane is expected to be back open in a couple of hours.
