SAN DIEGO (NEWS 8) - More than three dozen high school students were taken to a hospital for precautionary evaluations Wednesday after a car rear-ended their school bus in the University City area while they were on their way to classes, authorities reported.

An Infiniti sedan struck the school vehicle shortly before 8:30 a.m. on Genesee Avenue, just north of state Route 52, according to the California Highway Patrol.

CHP told News 8 a woman in her 70s was driving the Infiniti sedan that slammed into the back of the school bus. They believe a medical condition may have been the reason for the crash.

No serious injuries were reported, but medics took all 38 University City High School students who had been riding in the bus to a hospital to be checked out.
