The trailers collided and went up in flames in the eastbound lanes near milepost 11 before exit 11 in Bethlehem Township around 4:30 a.m., according to the Pattenburg Volunteer Fire Department.
The drivers had safely exited the vehicles upon arrival of the Bloomsbury Hose Co., which also assisted with fire suppression, they said.

All fire units cleared the scene by 9:45 a.m. while cleanup remained ongoing and reduced traffic to one lane, the department said.
The Clinton Fire Department also assisted at the scene.
Motorists were experiencing delays of up to 90 minutes near Route 614 and Pattenburg Road as of 9:40 a.m., according to 511NJ.
The cause of the crash was not immediately clear.
