SYSTEM OF
SIGNS is ADOPTED

prepared by the United States Department
of AKriculture.)
The joint board on interstate high
ways meeting at the United States
bureau of public roads In Washington,
D. O., adopted a system Of interstate
roads and a series of standard danger,
caution, direction and international
signs which it will recommend for use
in marking and signing the systems
selected.
The system adopted will now be
mapped and as promptly as possible a
full report will be made to the sec
rotary of agriculture by whom the
board was appointed last February.
The selected routes will be num-
bered in accordance with a system to
be evolved by a subcommittee of the
board.
The standard route marker viii be
a typical United States shield painted
white on which will appear, in black,
the name of the appropriate state, the
initials ~. s." and the route number.
If possible the route numbers will be
limited to two digits for easy reading,
and steps will be taken TO prevent the
use Of the standard marker for any
purpose other than for the marking of
the selected system Of interstate roads.
Other standard signs adopted by the
board were as follows:
A white shield in a smaller size
than the route marker on which Will
be printed the letters R or L as a
precautionary warning on the APP
proach of curves or turns in the
routes. A similar sign with the addi-
ton Of an arrow pointing in the proper
direction will be posted Immediately
at the turn.
A circular sign "a inches In diameter
with a yellow background and bearing
the familiar railroad cross in black
with the letters "R r" also in black
In the upper quadrants has been
adopted for use at railroad grade
crossings In all states in which exist
ing laws permit the use Of such a sign;
and the board recommends that the
use of the sign be authorized by suit
able legislation In all states.
The standard stop sign adopted is a
regular octagon with the word "Stop"
in black letters on a yellow back
ground.
The caution signs r diamond
shaped with a yellow background on
which are superimposed the warning
words and symbols giving notice OF
curves, hills, loose gravel, ETC., ahead.
In addition to these ca%utionary signs
provision has been made for the use OF
"look" or attention" signs to be used
sparingly on approaching schools and
other points at which caution may be
necessary. These signs will be square
with a yellow background and black
letters.
In the selection of colors and shapes
the board has been guided by the prin-
| ciple that all signs indicating the
necessity for any degree of caution
will be yellow. The degree Of caution
required will be indicated by the
shape Of the signs as well. as by the
words and symbols on them. Thus a
round sign will always Indicate a rail-
road crossing; an o%ctagonal sign will
indicate positive danger and will call
for a complete stop a diamond-shaped
sign will be equivalent to a command
to proceed with caution; and a square,
yellow sign will call attention to the
need for a lesser degree Of caution.
In addition to the warning and a u
tionary signs, standards were also
adopted for various forms of informa-
tional and directional signs, all Of
which are to be rectangular In form
and to have a white background with
black letters.
With respect to luminous signs the
action of the board at Its April meet
ing remains unchanged. The colors
approved are red for danger or stop.
yellow for caution, and green to In
dicate 60"
