Freeway Driving
Mile for mile, freeways — also called thruways,
parkways, expressways, turnpikes, or
superhighways — are the safest of all roads.
But they have their own special rules.The most important advice on freeway driving is:
Keep up with traffic and keep to the right.
Drive at the same speed most of the other drivers
are driving. Too-fast or too-slow driving breaks
a smooth traffic ow. Treat the left lane on
a freeway as a passing lane.
At the entrance, there is usually a ramp that leads
to the freeway. If you have a clear view of the
freeway as you drive along the entrance ramp, you
should begin to check traffic. Try to determine
where you expect to blend with the ow. Try to
merge into the gap at close to the prevailing speed.
Switch on your turn signal, check your mirrors, and
glance over your shoulder as often as necessary.
Try to blend smoothly with the traffic ow.
Once you are on the freeway, adjust your speed
to the posted limit or to the prevailing rate if it
is slower. Stay in the right lane unless you want
to pass.
Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.

Highway Hypnosis
Is there actually such a condition as highway
hypnosis? Or is it just plain falling asleep at the
wheel? Call it highway hypnosis, lack of
awareness, or whatever.
There is something about an easy stretch of road
with the same scenery, along with the hum of the
tires on the road, the drone of the engine, and the
rush of the wind against the vehicle that can make
you sleepy. Do not let it happen to you! If it does,
your vehicle can leave the road in less than a
second, and you could crash and be injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
Make sure your vehicle is well ventilated,
with a comfortably cool interior.
Keep your eyes moving. Scan the road ahead
and to the sides. Check your mirrors and your
instruments frequently.
If you get sleepy, pull off the road into a
rest, service, or parking area and take a nap,
get some exercise, or both. For safety, treat
drowsiness on the highway as an emergency.
Hill and Mountain Roads
Driving on steep hills or mountains is different
from driving in at or rolling terrain.

Before you start, check all trailer hitch parts and
attachments, safety chains, electrical connection,
lamps, tires and mirror adjustment. If the trailer
has electric brakes, start your vehicle and
trailer moving and then apply the trailer brake
controller by hand to be sure the brakes are
working. This lets you check your electrical
connection at the same time.
During your trip, check occasionally to be sure
that the load is secure, and that the lamps and any
trailer brakes are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead
as you would when driving your vehicle without
a trailer. This can help you avoid situations
that require heavy braking and sudden turns.
Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a
good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can
return to your lane.
Backing Up
Hold the bottom of the steering wheel with one
hand. Then, to move the trailer to the left,
just move that hand to the left. To move the trailer
to the right, move your hand to the right. Always
back up slowly and, if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could be
damaged. Avoid making very sharp turns
while trailering.
When you’re turning with a trailer, make wider
turns than normal. Do this so your trailer
won’t strike soft shoulders, curbs, road signs,
trees or other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
