What should you do before going down a steep hill? Use lower gears to go downhill When you start to head back downhill, use your engine and transmission to slow the car down instead of the brakes. Shift to a lower gear before you start heading downhill, as this will help slow down the car without you having to ride the brakes, says the National Park Service.
What is considered a steep hill?
Page 1. Steep slopes are legally defined as hillsides having a 15 foot, or greater, vertical rise over 100 feet of horizontal run, or 15% slope (Figure 1). They are often undesirable ar- eas for development due to the difficulty of building on steep grades.
