Road Signs
The road signs you see everywhere are
coded by color, shape and symbols. It's
a good idea to know these codes so that
you can quickly grasp the basic meaning
or intent of the sign even before you
have a chance to read it.
STOP DO NOT WRONG
ENTER W A Y
Color of
Road Signs
Red means Stop. It may also indicate
that some movement is not allowed.
Examples are Do Not Enter and Wrong
Way.
Green is used to guide the driver. Green
signs may indicate upcoming freeway
exits or show the direction you should
turn to reach a particular place.
RR ADVANCE
NARROW NO PASSING
CROSSING BRIDGE ZONE
Yellow indicates a general warning.
Slow down and be careful when you see
a yellow sign. It may signal a railroad
crossing ahead, a no passing zone, or
some other potentially dangerous
situation. Likewise, a yellow solid line
painted on the road means Don't Cross.
Blue signs with white letters show
motorists' services.
