Approaching a Hill
When you approach a hill, you need to decide if it's one of those hills that's
just too steep to climb, descend, or cross. Steepness can be hard to judge.
On a
very small hill, for example, there may be a smooth, constant incline
with only
a
small change in elevation where you can easily see all the way
to the top. On a large hill, the incline may get steeper as you near the top,
but you may not see this because the crest of the hill is hidden by bushes,
grass, or shrubs.
Here are some other things to consider as you approach a hill.
Is there a constant incline, or does the hill get sharply steeper in places?

Is there good traction on the hillside, or will the surface cause tire

Is there a straight path up or down the hill so you won't have to make
0
Are there obstructions on the hill that can block your path (boulders,
trees, logs or ruts)?
What's beyond the hill? Is there a cliff, an embankment, a drop-off,
a
fence? Get out and walk the hill if you don't know. It's the smart way
to find out.
slipping?
turning maneuvers?
0
Is the hill simply too rough? Steep hills often have ruts, gullies, troughs
and exposed rocks because they are more susceptible to the effects of
erosion.
Driving Uphi//
Once you decide you can safely drive up the hill, you need to take some
special steps.
0
Use a low gear and get a firm grip on the steering wheel.
0
Get a smooth start up the hill and
try
to maintain your speed. Don't use
more power than you need, because you don't want your wheels to start
spinning or sliding.
