•
What is beyond the hill? Is there a cliff, an
embankment, a drop-off, a fence? Get out and
walk the hill if you do not know. It is the smart way
to find out.
•
Is the hill simply too rough? Steep hills often have
ruts, gullies, troughs and exposed rocks because
they are more susceptible to the effects of erosion.
Driving Uphill
Once you decide you can safely drive up the hill, you
need to take some special steps.
•
Use a low gear and get a firm grip on the
steering wheel.
•
Get a smooth start up the hill and try to maintain
your speed. Do not use more power than you
need, because you do not want your wheels to start
spinning or sliding.
•
Try to drive straight up the hill if at all possible. If
the path twists and turns, you might want to find
another route.
{
CAUTION:
Turning or driving across steep hills can be
dangerous. You could lose traction, slide
sideways, and possibly roll over. You could be
seriously injured or killed. When driving up
hills, always try to go straight up.
•
Ease up on your speed as you approach the top of
the hill.
•
Attach a flag to the vehicle to make you more
visible to approaching traffic on trails or hills.
•
Sound the horn as you approach the top of the hill
to let opposing traffic know you are there.
•
Use your headlamps even during the day. They
make you more visible to oncoming traffic.
