The grade of a road is its slope given as a percent. for example, a road with a 6% grade has a slope 6/100. it rises 6 feet for every 100 feet of horizontal run. describe a 100% grade. Do you think you could drive up it?could you walk up it? Is it possible for a grade to be GREATER THAN 100%?...

According to the rule, a 100% grade rises 100 feet for every 100 feet of horizontal run. This makes a 45° angle with the horizontal.
Cars cannot drive up that slope, nor trucks. For someone to walk on it, it requires the friction. I managed to walk on a shingled roof of 40° on running shoes (so they don't slip) but it was not easy.
Yes, it is possible to have a grade of more than 100%, but probably not for a useful road.
