A spokeswoman at St. Joseph's Regional Medical Center says the three were in fair condition Sunday, but declined to provide further details on them or their injuries.

Authorities were still trying to determine what caused the crash, which occurred around 7:30 a.m. Saturday. The driver, who suffered a gashed arm told state police another driver cut him off.

The Record reports the operator of the bus, AVM Max 2000 of Toronto, has been cited numerous time for violating federal “fatigued driving” regulations including one occasion where a driver drove more than 11 hours.

State police say 23 people — including the driver and two young children — were hurt in the accident. There were 57 passengers aboard the bus, which left from Toronto and was bound for New York City.
