SAN JOSE -- An 82-year-old man suffered major injuries when he was struck by a school bus as he rode a bicycle through a major intersection bordering Cupertino and Saratoga Friday afternoon.

According to the California Highway Patrol, the man was hit at the intersection of Prospect Road and South De Anza Boulevard around 2:10 p.m.

Officer Chris Falkowski said the driver of the bus and students were not injured. He did not know how many students were on the bus -- which was a compact shorter model -- or what school it was affiliated with.

The man was transported to a hospital, but his condition was not known Friday evening.

What led to the crash is under investigation.

"Due to the complication of the large intersection where it happened, we are unsure what direction the bus or the bike were going," Falkowski said. "We are still conducting interviews."

While the intersection is technically in San Jose, it is on the border of both Cupertino and Saratoga. The CHP is handling the investigation because state legislation mandates the organization take over incidents involving the crash of a school bus with at least one student on board, Falkowski said.
