I knew a guy that was training a gal how to drive one of our snow plows, they were big IHC's with lousy crash box trannys, dump beds and sanders installed, oversized blades...too wide for city operation. They were a real challenge for those of us with some driving experience and we all told the guy he had no business trying to teach her. She came down a good sized hill in town and as he told the story he told her to slow down for an upcoming curve, she didn't slow down enough and over corrected for the sharp curve, instead of going wide on the corner. He said the truck went over on its side in a roll so slow that at one point he actually thought about opening his door and climbing out to jump off before it hit the center island and flipped over. It was a hell of a wreck, totalled everything on the truck, both of them suffered the effects for years, she never drove anything larger than a floor scrubber after that.
