Investigators told CNN the school bus was not traveling on its designated route at the time of the crash.
"We are investigating why it was not on the designated route," National Transportation Safety Board Chairman Christopher A. Hart said in a press conference.
Hart noted that NTSB is looking into whether the driver had taken that route before, and if so, why.

The Tennessee Bureau of Investigation determined Wednesday that bus driver Johnthony Walker was not under the influence of drugs or alcohol on Monday when he crashed his bus, killing five children and injuring six more, reports CBS News.
Walker was arrested after the crash and charged with five counts of vehicular homicide. He was speeding 30 mph over the limit when he lost control of the bus.
Walker is set to appear in court on Nov. 29.
None of the investigators are able yet to verify a chilling rumor about the crash.
The mothers of three children who were on the bus told the police and members of the media that Walker asked the children, "Are y'all ready to die," as they were speeding around a corner.
Walker did not have any prior charges to his name.
