None of the 20 students riding on a school bus were injured when it and a Ford van collided at Hastings Street and Central Avenue in South Williamsport about 8:20 a.m. Wednesday, borough police said. The female bus driver also was not hurt, police said.

However, the male driver of the van was taken by ambulance to UPMC Williamsport for treatment of non life-threatening upper body injuries, police said.

A witness told police the van reportedly went through a red light.

All the students were medically cleared on the bus, which could be driven from the scene, police said. It was a Susquehanna Trailways bus leased to the South Williamsport School District, police said.

The van sustained heavy front-end damage and had to be towed, police added.
