About 40 students were on the bus at the time, ABC New York station WABC-TV reported.
The number of people injured was not immediately clear.
Morristown Medical Center has received an unknown number of patients from the accident, a medical center spokeswoman said.
New Jersey state troopers used cadaver dogs to search for victims who may have been ejected, WABC reported.
Mount Olive Mayor Rob Greenbaum called the accident "horrific" in an interview with WABC.
The bus was from East Brook Middle School in Paramus, New Jersey, Paramus Police Chief Ken Ehrenberg said.
About 650 fifth- to eighth-grade students attend the school, according to its website.
