We have some hills well past 18%, but they are short. I will measure the incline of the road leading to my neighborhood in the morning. You have to start it at low speed of course, turning off the highway, and accelerate up it. I am curious what it is.Colorado steepest road has average grade of 14.2% and steepest parts of 18%.
There is difference between road and driveway.
