How does a downhill grade affect stopping?
Correct answer: Gravity adds speed and can lengthen the stop
Why
Gravity tends to increase a vehicle’s speed downhill. Control speed before it builds and leave additional stopping room; the same approach speed does not guarantee the same stopping distance as on level ground.
