A CHP dispatcher says the bus and truck were on opposite sides of the freeway when the truck crossed the median and slammed into the bus, causing an explosion and fire.
Investigators say the truck driver might have been trying to avoid a passenger car that was also involved in the crash, which shut down north- and south-bound traffic on the freeway.

No one in the car was injured.
