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 is slower. Stay in the right lane unless you
want to pass.
