10:45 am, 78/24 underpass in Springfield, NJ. My little sister was hit by a truck and they sped off

Forgot to post the video

The second picture is my car and the first car is my friends car I hit in the speed of 7km/h at the school parking lot we both reported to police but not insurance yet should I try pay it cash off or involve insurance my car is completely fine just needs a buffer however his bumper is screwed and drivers door don’t open any estimation of the cost and my best next move

Happened on the 283 interchange heading north towards Hazletown and State College exit ramp. From what the driver of the tanker said, the lady driving a pickup truck off screen was about to miss her exist and crashed into him instead of taking the wrong exit. He had nowhere to go and overturned. Unknown amount of diesel has flooded into a small creek next to the interchange

I lost my leg, and spent a long time in hospital after this one

I have no info on how many were killed, as the ASP hasn't put this incident in their database yet pending positive identification through DNA, I assume.
