V^hen you dnvE over obstaclea or iough lenain, keep a
firnn grip on the steering wheel. Ruts, troughs or
other surface fealures can jerk the wheel out et your
hands If you're rtol prepared.
Whert you dfiive over bumps, rocks, or other ebstaciBs.
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.
Because you will be on an unpaved surface, It's
especially Important to avoid sudden acceleration,
sudden turns or sudden braJ
In a way, off-road driving requires a different kind ol
alertness frann driving on paved roads and highways.
There are no road srgns^ posted speed limits or
signal lights. Vnu have to use yOur own good judgment
about what is safe and what isn't.
Drinking and driving can be very dangerous on any
road. And ihis is certainly true for off-rcad driving, At the
very time you need special alertness and driving
skills, your reflexes, perceptions and judgment can be
affected by oven a small amourtt of alcohol. You
could have a senous — or even falat — accident If you
drink and drive or ride with
a driver who has been
drinking. See Dfunhen Drving on page 4-2,
Driving on Off-Road Hills
Off-road driving often takes you up, down or across a
hill. Driving safely or; hills requires good judgment
and an understanding of what your vehicle can and can'l
do. There are some hills that simply can't be driven,
no matter how well built Ihe vehicle.
Many hills are simply loo steep for any vehicle,
if you drive up them, you will stall. If you drive
down them, you can't control your speed. If you
drive across them, you will roll over. You could
be seriously injured or kilted, if you have any
doubt about the steepness, don't drive tbe hill.
