Trooper Sean Link suffered a leg injury and was treated and released Tuesday from Capital Health Regional Medical Center in Trenton.
The driver of the car, Michael Fantry, 30, of Staten Island was also treated and released.
Fantry's wife, 27-year-old Jasmine Fantry, also of Staten Island, was a passenger in the car. She was admitted to Robert Wood Johnson Hospital in Hamilton, NJ with non-life-threatening injuries.
The accident happened Tuesday afternoon around 4:00 p.m.
Investigators now say a vehicle lost control on the westbound side of I-195 and veered off the road into the median.
They say Michael Fantry, traveling on the eastbound side, saw what was happening and reacted by abruptly hitting the brakes. The trooper then hit Fantry's car from behind.
Both cars burst into flames.
The view from Chopper 6 HD showed the charred vehicles resting in the median of the highway.
Traffic on eastbound I-195 was backed up for hours as crews worked to clear the scene.
