This change list was developed to acquaint readers of the 2009 Edition of the Manual on Uniform Traffic Control Devices (MUTCD) with the changes that have been incorporated into the 2009 MUTCD with Revision Numbers 1 and 2 by Final Rules dated May 2012. This change list compares the 2009 MUTCD with Revision Numbers 1 and 2 incorporated to the original 2009 Edition of the MUTCD, dated December 2009, which was the version that was printed and sold by AASHTO, ATSSA, IMSA, and ITE.

All references to Parts, Chapters, Sections, figures, tables, paragraphs, items, and pages in this change list refer to the 2009 MUTCD.

Section 1A.09 Engineering Study and Engineering Judgment

In Revision 1, a new Paragraph 3 has been added on Page 4 and the previous Paragraphs 3, 4, and 5 have been relabeled as Paragraphs 4, 5, and 6 respectively. The new Paragraph 3 says, "The decision to use a particular device at a particular location should be made on the basis of either an engineering study or the application of engineering judgment. Thus, while this Manual provides Standards, Guidance, and Options for design and applications of traffic control devices, this Manual should not be considered a substitute for engineering judgment. Engineering judgment should be exercised in the selection and application of traffic control devices, as well as in the location and design of roads and streets that the devices complement."

In Revision 1, the last sentence of Item A in Paragraph 1 on Page 10 has been deleted. The deleted sentence said, "Standard statements shall not be modified or compromised based on engineering judgment or engineering study."
