or hold short of the intersection, the sign array is not needed
unless the absence of guidance would cause confusion.
5. A runway exit sign identifying the exit taxiway should be
installed along each runway for each normally used runway
exit.
6. Destination signs may be substituted for direction signs at
the intersection between taxiways or for runway exit signs at
uncontrolled airports.
7. Standard highway stop signs should be installed on ground
vehicle roadways at the intersection of each roadway with a
runway or taxiway. For roadway intersections with taxiways,
a standard highway yield sign may be used instead of the
stop sign.
8. Additional signs should be installed on the airfield where
necessary to eliminate confusion or to provide confirmation
relative to location.

Signing Conventions
The FAA recommends the following signing conventions [25]:
1. Signs should be placed on the left side of the taxiway as viewed
by the pilot of an approaching aircraft. If signs are installed on
both sides of the taxiway at the same location, the sign faces
should be identical. Signs may be placed on the right side of
the taxiway when necessary to meet clearance requirements or
where it is impractical to install them on the left side because of
terrain features or conflicts with other objects.
2. Some signs may be installed on the back of other signs even
though this may result in the sign being on the right side of the
taxiway. Signs which may be installed in this manner include
a. Runway safety area, obstacle-free zone area, and runway
approach area boundary signs may be installed on the
back of taxiway-runway intersection and runway approach
area holding position signs.
b. Instrument landing system critical area boundary signs
may be installed on the back of instrument landing system
critical area holding position signs.
c. Taxiway location signs, when installed on the far side of the
intersection, may be installed on the back of direction signs.
d. Taxiway location signs may be installed on the back of
holding position signs.
e. Destination signs may be installed on the back of direction
signs on the far side of intersections when the destination
referred to is straight ahead.
