CAUTION:
Coasting downhill in NEUTRAL (N) or with the
ignition off is dangerous. Your brakes will have to
do all the work of slowing down. They could get
so hot that they wouldn’t work well. You would
then have poor braking or even none going down
a hill. You could crash. Always have your engine
running and your vehicle in gear when you go
downhill.
D Know how to go uphill. Use lower gears. They help
cool your engine and transmission, and you can
climb the hill better.
D 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.
D 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.
D 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,
winding roads and special truck lanes. Be alert to
these and take appropriate action.
