'Grade' is a the element of vertical alignment on a road, typically the topmost layer. A smooth road will have almost no grade which means a flat surface with no incline or decline in the road. A higher grade can indicate a rougher transition in road surface or an incline/decline such as a hill or dip. Higher grades have more impact on larger, heavier vehicles as more fuel is expended during increased torque on the engine and during breaking though smaller vehicles are still affected, just to a lesser degree.

The Rate of Change of Grade on Roadways Calculator allows you to calculate the rate of change of grade.
