A P.E.I. woman who was aboard a Maritime Bus that tipped over near Summerside Sunday says she's grateful to the nurse who kept passengers calm in the dark until ambulances arrived.

'She was great. She was really calm and she did all the checks.' — Passenger Natalie MacDonald

None of the 33 passengers were seriously injured. Some passengers were taken to the hospital with minor injuries.

Twenty-year-old Natalie MacDonald of Charlottetown was on her way to Halifax when the bus slid off the road, and flipped on its side. She was sitting next to the window.

"Really scary. I hit my head on one of the televisions that were screwed on to the ceiling of the bus and I blacked out for a minute," said MacDonald.

"There was actually a nurse on the bus. She was great. She was really calm and she did all the checks. She checked our pupils and our heads while we were waiting for the paramedics."

The Halifax-bound bus was actually returning to Charlottetown when the accident happened, having been turned back at Confederation Bridge because of high winds. Police said a gust of wind blew it off the slippery highway.

The passengers sheltered in a nearby residence until a smaller bus from Maritime Bus arrived to take them to their destinations.
