The Allamuchy Fire Dept. responded to the accident in the westbound lanes near milepost 19 in Allamuchy around 12 p.m. on Sunday, August 15, the squad said.
Upon arrival, crews found the trailer on its side with a ruptured fuel tank leaking diesel fuel onto the highway.
The HazMat team and Hope Fire Department was called to the scene due to the size of the spill, AFD said.

The remaining fuel was siphoned into containers to stop the leak as the HazMat team arrived.
The scene was cleared around 2:15 p.m.
