Traffic Signs and Signals
1954 MUTCD Revision
Though no new editions of the Manual on Uniform Traffic Control Devices (MUTCD) were
published the 1950s, a revision to the 1948 MUTCD was released in September 1954.
Significant changes:
*	 Stop sign color went from black on yellow to white on red.
*	 Prohibited the use of secondary messages on stop signs (a common practice
before the revision).
*	 The yield sign was first introduced, in the form of a yellow triangle with a black "yield
right of way" legend.3

AASHO Interstate Manual
In the 1950s, Traffic engineers felt that that current
MUTCD standards did not adequately address the
needs of the high-speed, controlled access nature of
the new interstate highways. To fill the gap, AASHO
published the first edition of the Manual for Signing
and Pavement Marking of the National System of
Interstate and Defense Highways in February 1958.3
New features:
*	 White on green guide signs
*	 Lowercase letters
*	 Green on white service signs
*	 Utilized larger sign sizes
