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 flow. 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 flow. 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 flow.
Once
you are on the freeway, adjust your speed to the
posted limit or to the prevailing rate
if it’s 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 isn’t another vehicle in your
“blind” spot.
Once you are moving
on the freeway, make certain you
allow a reasonable following distance. Expect to move
slightly slower
at night.
When
you want to leave the freeway, move to the proper
lane well
in advance. If you miss your exit, do not,
under any circumstances, stop and back up. Drive
on to
the next exit.
The exit ramp can be curved, sometimes quite sharply.

‘--b hway 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. Don’t let it happen
to you!
If it does, your vehicle can leave the road in less
thun CI secmd, 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 flat or rolling terrain.
If you drive regularly in steep country, or if you’re
planning to visit there, here are some tips that can
make your trips safer and more enjoyable. (See
“Off-Road Driving”
in the Index for information about
driving off-road.)

You should always attach chains between your vehicle
and your trailer. Cross
the safety chains under the tongue
of the trailer
so that the tongue will not drop to the road
if
it becomes separated from the hitch. Instructions
about safety chains may be provided by the hitch
manufacturer or by the trailer manufacturer. Follow
the
manufacturer’s recommendation for attaching safety
chains and do
not attach them to the bumper. Always
leave just enough slack
so you can turn with your rig.
And, never allow safety chains to drag on the ground.
If your trarler weighs more than
1,000 lbs. (450 kg)
loaded, then it needs its own brakes
-- and they must be
adequate. Be sure
to read and follow the instructions for
the trailer brakes
so you’ll be able to install, adjust and
maintain them properly.
Your trailer brake system can tap into
the vehicle’s
hydraulic brake system
only if:
The trailer parts can withstand 3,000 psi
(20 650 kPa) of pressure.
0 The trailer’s brake system will use less than
0.02 cubic inch (0.3 cc) of fluid from your vehicle’s
master cylinder. Otherwise, both braking systems
won’t work well. You could even lose your brakes. If
everything checks out this far, make the brake tap
at the port
on the master cylinder that sends the fluid to
the rear brakes. But don’t use copper tubing for this.
If
you do, it will bend and finally break off. Use steel
brake tubing.

Towing a trailer requires a certain amount of experience.
Before setting
out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that
the vehicle you are
driving is now a good deal longer and
not nearly as
responsive
as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
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.
