Investigators are trying to determine if a commuter bus ran a red light and broadsided another commuter bus, killing a driver and injuring 19 people.
The crash occurred around 6 a.m. Friday in Newark when a New Jersey Transit bus with only the driver aboard starting its route on the 59 Line slammed into a 13 Line bus.
The driver of the 59 Line bus died. The driver's name has not been released.
NJ Transit spokeswoman Nancy Snyder says there were about 20 people on the 13 Line bus.
Mayor Ras Baraka says seven of the injured were in critical condition.
The mayor says the preliminary investigation is centered on whether the 59 Line bus ran a red light at the intersection of Raymond Boulevard and Broad Street.
