A no-injury collision involving a school bus and a minivan occurred at the intersection of Ortega Street and 20th Avenue at 8:02 a.m. There were 43 children on board the bus, said California Highway Patrol spokesman Mike Ferguson.

“At this time it looks like it was not the school bus driver’s fault,” Ferguson said, adding it occurred in a parking situation. “It was a very, very minor crash.”

A traffic hazard was reported on westbound Interstate 80 just west of the Seventh Street onramp at 8:35 a.m.
