I've seen those signs before in eastern Tennessee between Chattanooga and Nashville, and also in Pennsylvania around Bethlehem. I know when the number's above 10, it's pretty friggin steep. I was also driving a moving van through Kentucky one time and couldn't maintain 30 MPH on the interstate on an incline.
Of course, I live in a place where you can park in neutral and not set the parking brake and your car will probably not move an inch.
