A heart-stopping collision on a highway could have ended in tragedy if not for some brave witnesses who jumped into action.
The shocking video above shows a jeep drift into the path of a tractor-trailer, instantly erupting into a ball of fire.
Sam Lachance, 18, was in the jeep, returning to college in New Hampshire.
Footage filmed from the vehicle behind shows a dad and his son carrying the badly burned teen from the jeep.
Sam's mother has since praised the heroes who saved her son's life.
