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 designs are provided in the form of a Supplement to the 2004 Edition of Standard Highway Signs.

The contents of the 2012 Supplement will be incorporated into the new edition of Standard Highway Signs and Markings, which is due to be released later this year. The new edition will contain the details for all signs and pavement markings in the 2009 MUTCD, expanded sign design guidelines, and details for symbolic traffic and lane-control signal indications.
