Interim Approval 17 for the Optional Use of Three-Section Flashing Yellow Arrow Signal Faces
The FHWA has issued Interim Approval 17 that permits the optional use for a protected/permissive turn phase of a three-section flashing yellow arrow (FYA) signal face that uses the middle section to show both the FYA and the steady yellow arrow. Agencies may also continue to use the four-section FYA signal face for protected/permissive turn phases that is described in Sections 4D.20 and 4D.24. This interim approval has no impact on the use of a three-section FYA signal face for a permissive only turn phase as described in Sections 4D.18 and 4D.22.
Standard Highway Signs and Markings
The 2009 MUTCD sign layouts are available. The Federal Highway Administration has developed the design details of the new signs added in the 2009 Edition of the MUTCD and signs whose designs have been modified in the 2009 MUTCD. The new and modified designs are provided in the form of a 2012 Supplement to the 2004 Edition of Standard Highway Signs.
The Manual on Uniform Traffic Control Devices, or MUTCD defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways, and private roads open to public traffic. The MUTCD is published by the Federal Highway Administration (FHWA) under 23 Code of Federal Regulations (CFR), Part 655, Subpart F.
The MUTCD, which has been administered by the FHWA since 1971, is a compilation of national standards for all traffic control devices, including road markings, highway signs, and traffic signals. It is updated periodically to accommodate the nation's changing transportation needs and address new safety technologies, traffic control tools and traffic management techniques.
On December 16, 2009 a final rule adopting the 2009 Edition of the MUTCD was published in the Federal Register with an effective date of January 15, 2010. States must adopt the 2009 National MUTCD as their legal State standard for traffic control devices within two years from the effective date. The Federal Register notice, which provides detailed discussion of the FHWA's decisions on major changes from the 2003 edition, can be viewed at http://edocket.access.gpo.gov/2009/pdf/E9-28322.pdf (PDF, 716KB).

On May 14, 2012 final rules adopting Revisions 1 and 2 of the 2009, MUTCD were published in the Federal Register with an effective date of June 13, 2012. The Federal Register notices, which provide detailed discussions of the FHWA's decisions can be viewed at:
