Authorities also are examining what caused the accident on the exit ramp from eastbound Interstate 80 to east bound Route 46 on Saturday.

The driver, 51-year-old Neville Larmond of Toronto, told authorities that another driver cut him off. The bus slid down an embankment before coming to rest on its side.

There were 57 passengers aboard the bus, which had left from Toronto and was bound for New York City. Many of the passengers were members of a Seventh-day Adventist church in Toronto.

Three people remain hospitalized in fair condition.
