Worst non-fatal crash.

What do you think was the worst non-fatal crash in motorsport?

1988 Cup at Talladega - Bobby Allison's huge crash a the front straight that damaged the catchfence and had to replace it around 2 hours. That's when restrictor plates were brought into the sport.

I might put more up later.

2010 Bathurst 1000 - Fabian Coulthard barrel rolls several times in the gravel at the Chase.

2009 Hungarian GP Qualifying - Felipe Massa is knocked out by a spring that hits him in the helmet, then crashes into a barrier.

2008 Samsung 500 Qualifying - Michael McDowell walks away after hitting the Turn 1 wall and then rolling several times.

2013 Drive4Copd 300 - Kyle Larson gets into the Catchfence at the finish. He was okay, but the crash left 30 spectators injured as a result.

Geoffrey Bodine.
Truck.
Daytona.

2009 Aaron's 499: Obviously.

The worst one I've seen is either Kenny Brack's at Texas or Bodine's at Daytona.

The Allison one BTW was 1987, '88 is the 1st year they started restricting the engine's more.

Zanardi's crash.

Well, there's Danny Ongais at Indy in 1981 (?).

And then, there's this.

These two happened in my homeland's Formula Truck, somehow it didn't ended in tragedy:

Kenny Brack's wreck at Texas in 2003, without a doubt
