Around 10:45 a.m., the three vehicles involved were heading west on the freeway near the Woodman exit. A white Honda hit the van, which swerved and hit a big rig. The driver of the van lost control and went across all lanes, ending up in the center median and rolling over.
The driver had minor injuries but the four elderly disabled passengers were seriously hurt and taken to UC San Diego Medical Center. The woman driving the Honda and the big rig driver were not injured.
Dozens of emergency workers and at least four ambulances responded to the scene.
