What it does

The purpose of this final rule is to make technical corrections to revise Standard, Guidance, Option provisions, and supporting information, relating to the traffic control devices in all parts of the MUTCD. The changes provide minor technical corrections and address editorial changes that have been identified since the 11th Edition of the MUTCD was published. The changes promote uniformity and ultimately improve and promote the safe and efficient utilization of roads that are open to public travel. The MUTCD, with these changes incorporated, is being designated as Revision 1 of the 11th Edition of the MUTCD.
