MUTCD Sign Code Index

An unofficial index, made by Roundabout

This Sign Code Index is not an official section of the MUTCD 11th Edition. We (Roundabout) built it as a convenience by harvesting every sign code from the manual and linking each to the section that defines it. A few rows don't have a picture yet.

Every sign and plaque code (R1-1, W11-2, …) is mapped to a picture of the sign, its name, and the section that defines it. Hover a thumbnail to enlarge it, or use your browser's find (Ctrl/Cmd-F) for a code.
