Driving on the Freeway
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. If
you are on a two-lane freeway, treat the
right lane as the slow lane and the left
lane as the passing lane.
If you are on a three-lane freeway, treat
the right lane as the slower-speed
through lane, the middle lane as the
higher-speed through lane, and the left
lane as the passing lane.
Before changing lanes, check your
rearview 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.
If you are moving from an outside to a
center lane on a freeway having more
than two lanes, make sure another
vehicle isn't about to move into the same
spot. Look at the vehicles two lanes
over and watch for telltale signs: turn
signals flashing, an increase in speed, or
moving toward the edge of the lane. Be
prepared to delay your move.
Once you are moving on the freeway,
make certain you allow a reasonable
following distance. Expect to move
slightly slower at night.
leaving the Freeway
When you want to leave the freeway,
move to the proper lane well in advance.
Dashing across lanes at the last minute
is dangerous. If you miss your exit do
not, under any circumstances, stop and
back up. Drive on to the next exit.
At each exit point is a deceleration lane.
Ideally it should be long enough for you
to enter it at freeway speed (after
signaling, of course) and then do your
braking before moving onto the exit
ramp. Unfortunately, not all deceleration
lanes are long enough-some are too
short for all the braking. Decide when
to start braking. If you must brake
on
the through lane, and if there is traffic
close behind you, you can allow a little
