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
slipping?
turning maneuvers?
0
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)?
0
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.
0
1s 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 Uphill
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.
0
Try to drive straight up the hill if at all possible.
Tf
the path twists and
turns, you might want to find another route.
0
Ease up on your speed as you approach the top of the hill.
0
Attach a flag to the vehicle to make you more visible to approaching
traffic on trails or hills.
