MUTCD 11th Edition, Revision 1¶
Last updated June 1, 2026
A searchable, deep-linkable copy of the Manual on Uniform Traffic Control Devices, the U.S. standard for traffic signs, signals, and pavement markings.
We're Roundabout Technologies, and we built this because we kept needing to search the manual, jump to a specific section, and send a teammate a link to the exact paragraph we were looking at, and it was a real pain to do so with the 1000 page pdf. We thought others would find it useful so we made it publicly available, and we hope it's helpful!
What Roundabout does¶
We build AI-powered traffic signals that use cameras to build a real-time, super-detailed 3D map of all cars, bikes, buses and pedestrians. Then they use that map to make optimal signal change decisions at every moment, for single intersections and across road networks. If that sounds interesting, you can subscribe to our newsletter or reach out at roundabout.tech/contact. We'd love to hear from you.

Browse the manual¶
Use the nav or the search box to move around Parts 1 through 9 and the appendices. Every numbered section has its own stable link, so a part page plus #4I.06 drops you right on that section. Clicking the section header copies the link to that section.
Unofficial convenience copy
This isn't the official, controlling document though we will try to keep it as accurate and up to date as possible as new revisions and editions come out. The MUTCD is a public-domain work of the U.S. federal government. For the authoritative text, use the official edition from the Federal Highway Administration.
