Traffic collision on 101 this morning involved four vehicles, including two Peterbilts (updated 3pm)

UPDATE 3:00 p.m. — The California Highway Patrol has released more information about the multiple car collision that closed Highway 101 for almost an hour this morning just north of the Willits bypass, and restricted traffic for a number of hours on Monday afternoon.

The collision involved four different drivers, the first of whom initially stopped due to a “traffic hazard” in the road ahead, and the rest proceeded like a series of dominoes.
