There were 2 crashes.
If you are talking about first one with a car going into the barriers, he was fine and the car’s front completely disintegrated.
If you’re talking about second crash and safety car, 2 LMP2 cars tangled, one of them got away but other one spun and stayed there on track. Soon enough, that stationary car received a massive hit from another LMP2 car. All drivers involved were declared fit.
