WAYNE, N.J. – A tour bus from Canada carrying about 60 people bound for New York City overturned on a highway exit ramp in northern New Jersey early Saturday, slid down an embankment and landed on its side, injuring 23 people on board, authorities said.

The driver, who suffered a gash in his arm, told state police that he was cut off by another vehicle, though it was not immediately clear whether that caused the crash around 7:30 a.m. on eastbound Interstate 80 in Wayne.

Some windows burst during the crash and their frames pinned three people, but they were quickly freed and taken to hospitals with the other injured. The bus had been chartered by a church group.
