The trailer — which was carrying auto parts — was heading westbound in Allamuchy when it overturned near milepost 19.2 just before 4:40 a.m., NJSP Trooper Brandi Slota told DailyVoice.com.
The driver suffered minor injuries in the crash, Slota said.
All lanes were closed west of Exit 19 to Route 517 following the accident, causing a 10 to 15 minute delay, according to 511NJ.
The lanes have since reopened.
