The girl, a San Bruno resident, struck the van at an unknown speed, likely while riding home from Parkside Intermediate School, where she is a student, San Bruno Police Department Cmdr. Matt Campi said.
She suffered “severe injuries” and was taken to S.F. General Hospital.
The accident occurred at Niles and Oak avenues at 2:59 p.m., Campi said. The female driver of the van stopped and police said they do not believe she will be charged.
The girl suffered head trauma, fire Chief Dennis Haag said. She was taken immediately to the hospital, where her mother later arrived, he said. The girl has not been identified because she is a minor.
Parkside is located at 1801 Niles Ave., about one-fifth of a mile from where the accident occurred.
