Jason Leffler died Wednesday night following a crash in a 410 Sprint Cup car race at Bridgeport Speedway in New Jersey. He was 37 years old.
Leffler passed away shortly after 9 p.m., N.J. State Police said. He had to be extricated from the car after striking a wall half an hour earlier.
Leffler's car hit the wall twice and "then it was flopping all over," a witness said.
He was transported to Crozer-Chester Medical Center, and pronounced dead.
