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.
