I've been upside down in a car, and I've been upside down a couple of times in a truck. I've never (fingers crossed) been upside down in a tractor. However, each time I've been upside down in a car or truck, I didn't think I would end up that way. The vehicle "upsets" (as the police reports call them) all came on short trips for me. Twice they were from getting drilled by another vehicle and once was due to over-correcting after getting two tires off of the road and then getting a truck sideways. Now, I really don't think I'll get hit by a vehicle while I'm on my tractor, and I really don't think I'll over-correct and turn the tractor over (but I could). Anyway, I now always wear my seatbelt on my tractor unless I'm just pulling it in or out of the barn. With my luck, I'll over correct backing out into my driveway and then get hit by the UPS guy! /forums/images/graemlins/blush.gif
