I've tried to figure out ways to limit my personal liability but never came up with a good answer.
If the worst happens and your truck comes unglued and tosses parts into the stands, I would imagine everyone will get sued: the promoter/sanctioning body, the track, the truck owner, and the truck operator.
Assuming no one did anything intentionally, a civil suit will be filed.
The promoter has event insurance so he is covered to some extent.
The truck owner and operator would get nailed if they could show that you were negligent in some way. This would be easy for a good lawyer, since most guys I know don't inspect every part before each hook, and wouldn't have the means to do it anyway, or the documentation showing it (and what standards apply?). Think FAA inspection-level stuff.
We all know that we stretch every part in these things to well beyond the original design limits so the plaintiff's lawyer would have a field day.
So I'm not so much worried about the truck, it's what the truck does on the track that worries me, and I'm not sure there's any way to cover that or anyone who will write a policy, aside from Lloyd's of London, for personal liability.
What are the promod drag guys doing? There's a boatload more of them out there, way more than us. Someone must know.
I know the probability is small, but I would sure hate to lose everything I own doing this.
