PUTNEY, Vt., Dec. 4 (UPI) -- The driver of a tour bus that rolled over with 44 college students aboard Friday was hospitalized in Vermont, authorities said Saturday.
All 17 college students injured in the crash had been treated and released from hospitals, The Boston Globe reported.
State police Sergeant Michael Sorensen said he saw "clear patterns of dirt," but no indication that the driver applied the brakes as the tour bus crossed the median of Interstate 91 near Brattleboro, Vt., before rolling over in a crash that involved no other vehicles.
One of the University of Massachusetts Amherst students said the driver went limp and slouched forward before the accident, while others said he had suffered a heart attack.
The bus was one of eight carrying students to a ski trip in Quebec, Canada, Friday.
Joseph Schoppy, the owner of Tour World, which operates the buses, said the injuries sustained by the students "seem very minor," CNN said.
Eight students were treated for minor injuries and released from Brattleboro Memorial Hospital, a hospital spokeswoman said. Eight others were treated for minor injuries at Springfield Hospital, a hospital official said.
Other passengers on the bus were picked up by a school bus and eventually were transported to White River Junction, where they had the choice of either continuing on to Quebec or returning to Massachusetts, CNN said. Schoppy said the other seven buses chartered for the trip continued on to Quebec for the ski trip.
