Authorities have put out some details about the multi-vehicle pileup that caused chaos on Highway 99.
It appears a semi-trunk collided with the back end of an Astro van just before 9 a.m. on Tuesday, north of the tunnel.
It led to a chain reaction of several vehicles being rear-ended.
The last vehicle to be hit, a Toyota Highlander, flipped onto its side from the impact.
Police say they’re amazed no one was seriously hurt or killed.
