Scanning the Terrain
Off-road driving can take you over
many different kinds of terrain. You
need
to be familiar with the terrain and
its many different features. Here

some things to consider.

Conditions.
Off-roading can
take you over hard-packed dirt; gravel,
rocks, grass, sand, mud, snow or ice.
Each
of
these surfaces affects the
steering, acceleration, and braking of
your vehicle in different ways.
Depending upon the kind of surface you
are
on,
you may experience slipping,
sliding,

acceleration, poor traction. and longer

Surface Obstacles.
Unseen or hidden
obstacles can be hazardous.
A
rock, log,
hole, rut, or bump can startle
you
if
you’re not prepared for them. Often

When you drive over obstacles or rough
terrain, keep
a
firm
grip
on
the steering
wheel. Ruts, troughs, or other surface
features can jerk the wheel out of your
hands if you’re not prepared.
When you drive over bumps, rocks, or
other obstacles,
your
wheels can leave
the ground.
If
this
happens, even with
one or two wheels, you can’t control the
vehicle as well or at
all.
