A truck, similar to the one depicted in this slide, was involved in a fatality because it was being operated on a steep grade of 26%. The truck was not designed to operate a grade this steep. Company personnel misunderstood the charts in the operator’s manual as to how steep a road should be. Always check with the manufacturer on interpreting those charts and make sure they designed that piece of equipment for the slopes you’re using it on.
