Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transaxle. These parts can work hard on mountain
roads.

Know how to go down hills. The most important
thing to know is this: let your engine do some
of
the
slowing down. Shift to a lower gear when you go
down a steep or long hill.
Know how to go uphill. Drive in the highest gear
possible.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don't swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could
be something in your lane, like a stalled car or an
accident.
You may see highway signs on mountains that warn
of special problems. Examples are long grades,
passing or no-passing zones, a falling rocks area, or
winding roads. Be alert to these and take appropriate
action.
