Highway Hypnosis

Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep the interior
temperature cool.
Keep your eyes moving
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.

Hill and Mountain Roads

Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced and in
good shape.
Check all fluid levels and brakes,
tires, cooling system, and
transmission.
Shift to a lower gear when going
down steep or long hills.
Using the brakes to slow the
scan
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
Warning
Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
Stay in your own lane. Do not
swing wide or cut across the
center of the road. Drive at
speeds that let you stay in your
own lane.
Be alert on top of hills;
something could be in your lane
(stalled car, accident).
Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
