Texas MUTCD (TMUTCD)

Last updated July 27, 2026

A searchable, deep-linkable copy of Texas MUTCD (TMUTCD), the Texas standard for traffic signs, signals, and pavement markings.

Texas MUTCD (TMUTCD) is Texas's own complete adoption of the Federal Highway Administration's MUTCD 11th Edition (the National MUTCD 2023), published as a full state manual. This edition mirrors that manual in full. Looking for the federal manual instead? See the National MUTCD 11th Edition.

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 source PDFs. 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 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.

How to use this edition

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 #4C.03 drops you right on that section. Clicking the section header copies the link to that section. The Sign Code Index maps every sign code (R1-1, W1-1, EM2-1, …) to a picture of the sign and the section that defines it.

Other editions

The MUTCD's federal base is adopted, sometimes as a full state manual and sometimes with state-specific amendments. We mirror these the same way, each at its own permanent link.

For the current list of every edition we publish, see State editions on the National MUTCD home page.

Unofficial convenience copy

This is not the official, controlling document. The authoritative texts are the Texas source (https://www.txdot.gov/business/resources/traffic-design-standards/tmutcd.html) and the National MUTCD from the Federal Highway Administration. We will keep this as accurate and current as we can.
