REVERSIBLE tANE ON MULTtlANE ROADWAY
Many city roads and expressways, and
even bridges, use reversible-lane traffic
control during rush hours. A red X light
above a lane means no driving in that
lane at that time. A green arrow means
you may drive in that lane. Look for the
signs posted to warn drivers what hours
and days these systems are in effect.
NO PASSING ZONE
Pavement Markings
Pavement markings add to traffic signs
and signals. They give information to
drivers without taking attention from the
roadway. A solid yellow line on your
side of the road or lane means Don't
Cross.
bur Own Signals
Drivers signal to others, too. It's not
only more polite, it's safer to let other
drivers know what you are doing. And
in some places the law requires driver
signals.
Turn and Lane Change Signals:
Always signal when you plan to turn or
change lanes.
If necessary, you can use hand signals
out the window:
Left
arm straight out
for a left turn, down for slow or about-
to-stop, and up for a right turn.
Slowing Down: If time allows, tap the
brake pedal once or twice in advance of
slowing or stopping. This warns the
driver behind you.
Disabled: Your four-way flashers signal
that your vehicle is disabled or is a
hazard. See the Index under Hazard
Warning Flashers.

The traffic police officer is also a source
of important information. The officer's
signals govern, no matter what the
traffic lights or other signs
say.
The next section discusses some of the
road conditions you may encounter.
