steep grade
Hill road warning
A steep grade is an incline with a sharp rise or fall relative to horizontal distance—a hill that climbs or descends rapidly.
The term appears most often in contexts involving roads, railways, and trails: Trucks should use low gear on steep grades.
Warning signs mark steep grades for drivers, typically when the slope exceeds 6-8 percent.
