The NSRA inspection is optional, if the owner chooses to.
What I meant was that they don't have the right to tell me that my vehicle needs something that isn't specified by the Transportation Safety Act. Sure, they can say I can't go in the show, and I wouldn't. My truck has all the safety equipment required by the Transportation Safety Act, and even some extras, but it's not the place of a show organizer to tell me what I need and don't need. That's just a personal thing, I guess. I'm not screwing a fire extinguisher to my kick panel just to make some guy with a clipboard happy.
