Hidden obstacles can make the steepness of the
incline even worse. I f you drive across a rock with
the uphill wheels, or if the downhill wheels drop into
a rut or depression, your vehicle can tilt even more.
For reasons like these, you need to decide carefully
whether to try to drive across an incline. Just because
the trail goes across the incline doesn't mean you
have to drive it. The last vehicle
to
try it might have
rolled over.
Q.'
What if I'm driving across an incline that's not
too steep, but
I
hit some loose gravel and start to
slide downhill. What should
I do?
A:
If you feel your vehicle starting to slide sideways,
turn downhill. This should help straighten out the
vehicle and prevent the side slipping. However, a
much better way to prevent this is to get out and
"walk the course" so you know what the surface is
like before you drive it.

Driving across an incline that's
too
steep will
make your vehicle roll over. You could be
seriously injured or killed. If you have any doubt
about the steepness of the incline, don't drive
across it. Find another route instead.
