Change List for the 2003 Edition of the MUTCD
This change list
was developed to acquaint readers of the 2003 Edition of the Manual
on Uniform Traffic Control Devices (MUTCD) with the significant
changes that have been incorporated into the MUTCD since the Errata
Version of the 2000 MUTCD was placed on FHWA's MUTCD website on
June 14, 2001. This change list compares the 2003 MUTCD to the Errata
Version of the 2000 MUTCD, which was the version that was printed
and sold by AASHTO, ATSSA, and ITE.
The changes regarding the application of accessible pedestrian signals
that were incorporated into the 2000 MUTCD in July 2002 as Revision
1 are included in this change list and are clearly marked as "Revision
1 changes".
All references to Parts, Chapters, Sections, figures, tables, paragraphs,
items, and pages in this change list refer to the 2003 MUTCD, unless
specifically stated otherwise for a particular reference.
General Items
A new cover design was developed for the 2003 Edition of the MUTCD
in order to make it easily distinguishable from the 2000 Edition.
An individual cover design (with a similar theme as the overall
cover) was developed for each of the ten Parts.
The format of the pages was changed in order to significantly reduce
the overall number of pages in the MUTCD. Margins were decreased
and the amount of space between lines and paragraphs was decreased.
All text is now in 11-point font size, including Standards and Guidance,
which were in 12-point font size in the 2000 MUTCD. As a result
of these various format changes, there is a lot less "white
space" on most of the pages.
In order to maintain accuracy, appropriate changes were made to
the various Tables of Contents, footers, and cross-references throughout
the MUTCD.
The date in the header at the top of each page was changed from
"December 2000" to "2003 Edition". The date
of "June 2001" was deleted from the footer at the bottom
of each page.
The issue dates of the Chapters that were shown in the Tables of
Contents of the 2000 MUTCD were deleted.
In figures that contain only a set of sign images, the relative
sizes of the signs are shown appropriately.
The legends on the word message sign images have been converted
to "highway gothic" font to more accurately represent
the actual appearance of the sign legends. Symbols on sign images
have also been made more pattern accurate.
Where metric units for sign legends in both the text and on the
sign images were shown in upper-case letters (such as "KM"
or "M"), they have been changed to lower-case letters
(such as "km" or "m").
Introductory Pages (Pages i and ii)
Internet addresses were added for all of the organizations in the
list.
Acronyms were added for each organization for which an acronym was
appropriate.
The following five organizations were added to the list:
· Federal Highway Administration Report Center
· International Organization for Standards
· ISEA - The Safety Equipment Association
· Occupational Safety and Health Administration
· U.S. Architectural and Transportation Barriers Compliance
Board
The suite number in the AASHTO address was changed from "225"
to "249".
Introduction (Pages

In the first sentence of Paragraph 2 ["The Manual on …"],
the phrase "traffic control devices on all public roads"
was changed to "all traffic control devices installed on any
street, highway, or bicycle trail".
In the second sentence of Paragraph 3 ["Any traffic control
…"], the phrase ", trademark," was added after
the word "patent", and the phrase "and any other
items owned by FHWA" was added at the end of the sentence.

which stated that "Section 15-104 of the UVC adopts the MUTCD
as the standard for conformance", was deleted.

in …"], the word "large" was deleted after "bold".

it is not bold", was deleted.

in …"], the word "small" was changed to "unbold".
In the second sentence of Item 4 of Paragraph 9 ["When used

that numerals that appear on sign images shown in the MUTCD are
intended to only be examples of the sign legends that could be used.
Paragraphs 13 ["Starting with the …"], 14, and 15
were added to clarify the proper manner of referring to a specific
portion of the text.
Paragraph 16 ["In accordance with …"] and the several
pages of compliance dates that follow were added so that readers
will have a convenient place to determine if a particular aspect
of the MUTCD has been given a special compliance date. Special compliance
dates associated with the 2000 MUTCD and with earlier Final Rules
are also included in this list.
Paragraphs 17 ["In order for …"] and 18 were added
to clarify what maintenance personnel should do when replacing a
damaged non-compliant traffic control device.
Table of Contents (Pages
TC-1 to TC-2)
The Table of Contents at the beginning of the MUTCD was changed
to list only the names of the Parts and Chapters, but not the Sections,
Figures, or Tables. Also, since each Chapter is individually numbered
starting with Page 1, page numbers were eliminated in the Table
of Contents at the beginning of the MUTCD. The more detailed Tables
of Contents at the beginning of each Part that show page numbers
for Sections, Figures, and Tables were retained (with appropriate
changes) in the 2003 MUTCD.
