YOLO COUNTY (CBS13) — A big rig driver escaped being hurt after the trailer they were hauling somehow detached and crashed down an embankment off Interstate 5 on Friday morning.

The crash happened a little before 8 a.m. along the northbound side of the freeway, just outside of Woodland.

Exactly what led up to the crash is unclear, but a FedEx truck ended up detached from its trailer. The trailer then fell down the side of the freeway and flipped over.

Authorities say the driver is OK.
