Controlling your vehicle is the key to successful
off
-
road driving. One of the best ways to control your
vehicle is to control your speed. Here are some things to
keep in mind. At higher speeds:
D you approach things faster and you have less time to
scan the terrain for obstacles.
D you have less time to react.
D you have more vehicle bounce when you drive
over obstacles.
D you’ll need more distance for braking, especially
since you’re on an unpaved surface.
CAUTION:
When you’re driving off
-
road, bouncing and
quick changes in direction can easily throw you
out of position. This could cause you to lose
control and crash. So, whether you’re driving on
or off the road, you and your passengers should
wear safety belts.
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 are some things
to consider.
Surface 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, wheel spinning,
delayed acceleration, poor traction and longer
braking distances.
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 these obstacles are
hidden by grass, bushes, snow or even the rise and fall of
the terrain itself. Here are some things to consider:
D Is the path ahead clear?
D Will the surface texture change abruptly up ahead?
D Does the travel take you uphill or downhill?
(There’s more discussion of these subjects later.)
D Will you have to stop suddenly or change
direction quickly?
