A Greyhound Bus crashed off Interstate-81 North in Binghamton.
The driver lost control while taking Exit 4.
The bus slid 50 feet off the ramp and slammed into a tree.
7 people were hurt and brought to the hospital for minor injuries.
There appeared to be a few dozen people who were on board.
"It happened so quickly, so a lot of people hit their head on the chairs in front of them," says Debra Gleaser of New York City.
"Before I could even try to cover my face or anything, it was over," says Kenneth Carl Martin of Endicott.
Binghamton Fire Fighters who responded say a student driver was at the wheel.
He was being observed by a senior driver for Greyhound.
Another bus was brought in to pick up the passengers who were headed for Syracuse.
The cause of the crash is still under investigation.
