The crash was first logged shortly before 4:35 p.m. and initially blocked one to two lanes, with traffic diverted onto the shoulder, the CHP said. Units on scene worked to clear the roadway and reported all lanes reopened by about 5 p.m. The agency said three people were transported from the scene.

Two tow trucks were requested to remove vehicles from the roadway.
The investigation remains open. We hope everyone who was hurt makes a speedy recovery.

Frequently Asked Questions
What typically causes a crash involving three or more vehicles?
Multi-vehicle crashes usually happen when one vehicle slows or stops suddenly and following drivers cannot react in time, triggering a chain reaction. Traffic congestion, reduced visibility and tailgating are common contributing factors.
Why do these chain-reaction crashes happen so quickly?
Once the first impact occurs, following vehicles usually have only seconds to brake or swerve, especially at highway speeds, which makes a secondary or third collision hard to avoid.
How can drivers stay safer in heavy traffic to avoid getting caught up in one?
Leaving extra following distance, staying alert to brake lights well ahead, and slowing early when traffic is congested can help give drivers more time to react.
What should I do if I come upon a crash scene on the highway?
Slow down well before reaching the scene, follow any directions from officers or flaggers, and if directed to a shoulder or alternate lane, merge early and carefully.
