Driving Downhill
When off-roading takes you downhill, you'll want to
consider a number of things:
e
How steep is the downhill? .Will I be able to maintain
vehicle control?
What's the surface like? Smooth? Rough? Slippery?
Hard-packed dirt? Gravel?
-
Are there hidden surface obstacles? Ruts? Logs?
Boulders?
e
What's at the bottom of the hill? Is there a hidden
creek bank or even a river bottom with large
rocks?
If you decide you can go down a hill safely, then try to
keep your vehicle headed straight down, and use a
low gear. This way, engine drag can help your brakes
and they won't have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
cause your brakes to overheat and fade. This
could cause loss of control and a serious
accident. Apply the brakes lightly when
descending a hill and use a low gear to keep
vehicle speed under control.
