The crash occurred on the southbound side near milepost 70.7 in Cranbury around 7 a.m., State Police said. The State Troopers Fraternal Association of NJ later tweeted that the officer "is currently alert and conscious."
The state trooper was taken to an area hospital with non-life-threatening injuries, they said.
“How that trooper lived, is unbelievable,” State Police Superintendent Patrick Callahan said during a daily briefing with Gov. Phil Murphy.
Callahan said that being thrown from the vehicle is likely what saved the trooper’s life.
Video from abc7ny.com shows the trooper’s car with serious damage along the side of the turnpike and the dump truck rolled over.
Southbound traffic backed up for several miles during rush-hour.
"Our Trooper involved in this morning’s terrible Turnpike crash is currently alert and conscious. He is at a local hospital and having tests done now. Please keep him in your thoughts and prayers!!" the STFA wrote on Twitter.
