The bus was transporting students from East Brook Middle School in Paramus, New Jersey, according to a school official.

Jay Faltings, who drove past the scene about five minutes after the crash, told HLN he saw children being rescued from the wreckage.

Faltings said the front of the dump truck appeared to have been sheared off.

The school bus was “ripped off its frame” after hitting a guard rail and flipping over.

“It’s like nothing you’ve ever seen before,” he said.

Faltings said first responders appeared to have removed the children from the scene.

“They were young kids,” he said. “But luckily, first responders, everybody there helped get all the kids out safely from what we could see… The kids were obviously freaked out.”

The National Transportation Safety Board said via Twitter that it was “gathering information” on the crash.

All lanes of Interstate 80 have been shut down.

Mount Olive Township is about 50 miles west of New York City.
