Driving Downhill
When off-roading takes you downhill, you will want to
consider a number of things:
• How steep is the downhill? Will I be able to
maintain vehicle control?
• What is the surface like? Smooth? Rough?
Slippery? Hard-packed dirt? Gravel?
• Are there hidden surface obstacles? Ruts?
Logs? Boulders?
• What is a tthe 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 the brakes and
they will not have to do all the work. Descend slowly,
keeping your vehicle under control at all times.
{ CAUTION:
Heavy braking when going down a hill can
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.
Q:
Are there some things I should not do when
driving down a hill?
A:
Yes! These are important because, if you ignore
them, you could lose control and have a serious
accident.
• When driving downhill, avoid turns that take you
across the incline of the hill. A hill that is not too
steep to drive down may be too steep to drive
across. You could roll over if you do not drive
straight down.
• Never go downhill with the transmission in
NEUTRAL (N). This is called “free wheeling.”
The brakes will have to do all the work and
could overheat and fade.
