8Accessories should be rigidly and securely
mounted. An accessory which can shift posi-
tion or come off while you are riding could
affect your ability to control the ATV.
8Do not mount an accessory where it could
interfere with your ability to control the ATV.
Examples include (but are not limited to) a
heavy or bulky object attached to the handle-
bars which could make steering difficult, an
accessory that limits your ability to move
around on the seat, or one that limits your
view.
8Use extra caution when riding an ATV with
accessories. The ATV may handle differently
than it does without accessories.

CROSSING A SLOPE
Traversing a sloping surface on your ATV
requires you to properly position your weight to
maintain proper balance. Be sure that you have
learned the basic riding skills on flat ground
before attempting to cross a sloping surface.
Avoid slopes with slippery surfaces or rough ter-
rain that may upset your balance.
As you travel across a slope, lean your body in
the uphill direction. It may be necessary to cor-
rect the steering when riding on loose surfaces
by pointing the front wheels slightly uphill. When
riding on slopes be sure not to make sharp turns
either up or down hill.

SLIDING AND SKIDDING
Care should be used when riding on loose or
slippery surfaces since the ATV may slide. If
unexpected and uncorrected, sliding could lead
to an accident. To reduce the tendency for the
front wheels to slide in loose or slippery condi-
tions, positioning your weight over the front
wheels will sometimes help.
If the rear wheels of your ATV start to slide side-
ways, control can usually be regained (if there is
room to do so) by steering in the direction of the
slide. Applying the brakes or accelerating is not
recommended until you have corrected the
slide.
