New MUTCD!!!
On Tuesday, December 19th, 2023, FHWA published the new 11th edition of the MUTCD. The supersedes and replaces the 2009 edition as the “official” MUTCD at a national level as of January 18th, 2024. Individual states have until January 2026 to adopt the new national MUTCD, a state-specific supplement, or a state-specific MUTCD, subject to review and concurrence from FHWA.
What does this mean for the Manual of Traffic Signs?
Well, a lot of work. First will be an assessment of how many new and revised signs are in the new 11th Edition. Next will be a data revision to assign existing and new signs to the correct sections of the new MUTCD for linking purposes, then the work of creating the new signs based on the revised Standard Highway Signs and Markings document, and then rebuilding the website with all the new material and corrected links.
This will not happen instantly, especially given other obligations and activities. But we do hope to have the MOTS updated and compliant with the new 11th Edition in a timely manner. Until then, we thank you for your patience, enjoy the site, and watch this space for updates.
Happy New MUTCD Day, a merry Christmas and happy holidays to all, and hoping for a good 2024.
Update:
In its update to the FHWA MUTCD website, this piece of information: “Starting with the 11th Edition of the MUTCD, FHWA no longer provides the MUTCD in a companion HTML format.” What this means is that this website can no longer link directly to FHWA HTML webpages with official MUTCD text, and many browsers do not support direct links to locations within PDF files – just the beginning of the PDF. Needless to say, if you want to link to 2B.74 and the PDF opens to 2B.01, that’s not very useful. So another time-consuming task will likely be importing the MUTCD as HTML into trafficsign.us, adding anchors for direct links, and fixing formatting as needed… and then having to keep that information updated as revisions are issued. This could result in more delays, alas. But we’ll get working on it soon.
And more info on the Standard Highway Signs and Markings page: “The new edition of Standard Highway Signs will contain the details for all signs and pavement markings in the 11th Edition of the MUTCD, expanded sign design guidelines, and details for symbolic traffic and lane-control signal indications. It is taking some additional time to prepare the publication, and information is expected to be posted in the coming months.” So this could also delay updates, as until the revised SHSM is published, any sign design we come up with will be based off MUTCD figure graphics, and not on official FHWA data.
New Job, Same Old Website
I (Richard, site creator & owner) have been involved with the National Committee on Uniform Traffic Control Devices (NCUTCD) since 1996, when I was approved to be a charter member of the then-brand-new Bicycle Technical Committee. I’d already been professionally involved with traffic control for several years prior to this, and had launched this Manual of Traffic Signs website earlier in 1996.
Through the years, I served in a number of different positions in NCUTCD. I became a voting member on the NCUTCD Council in 1999 (representing LAB, then AASHTO), and chaired the Bicycle Technical Committee for 15 years from 2002 to 2017, during a time when traffic control for cyclists underwent many notable changes.
And now, I am honored to move on to another position with the National Committee – that of Associate Executive Secretary. My firm, Moeurgineering PLLC, has been retained by NCUTCD to provide executive support services to NCUTCD, including helping to organize and arrange the two general meetings per year, maintain databases and records, and provide operational support to the Chair, Board, technical committees, and membership. I’ll be working alongside Bob Garrett, the current Executive Secretary, for the next several months, and it’s anticipated I will take over as Executive Secretary for the National Committee once Bob retires in the spring of 2020.
One thing I will not be doing: leading the National Committee. That is the role of the Chair, selected by the Council, and currently most ably filled by the legendary Gene Hawkins. Gene leads the committee – I just help him out.
I will continue to operate my engineering firm, and will continue to take on clients and work that won’t create a conflict of interest with my role with NCUTCD (in other words, no more expert witness work for the foreseeable future). The Manual of Traffic Signs will also continue to be an independent activity of mine, just as it was during my ADOT employment.
So don’t expect any major changes to the MOTS due to this new role – the site will chug along as it always have, and won’t be absorbed into NCUTCD. We’re all still waiting for the draft of the new edition of the MUTCD to be released for public comment, and once the Final Rule is issued and the new edition is final, I plan to promptly update this site accordingly. And I’m hoping to get the MUTCD Wiki up and running by year’s end.
Looking forward to this next chapter!
FINISHED!!!
(for now, anyway)
As of 6 PM MST on October 30th, 2019, the Manual of Traffic Signs update and revamp is hereby declared to be complete. Over two years and thousands of hours of work in creating hundreds of all-new sign files and user-editable PDFs is finished. The result has been uploaded and stands ready to satisfy your traffic sign information needs.
I’ve finished the rest of the D series signs and revised the webpages to more clearly denote which signs have PDF files that are user-editable. I also rearranged the main page to group similar items and emphasize content.
There are still two items of unfinished business:
I haven’t yet created the page(s) for E series freeway and expressway guide signs, as many of those signs don’t have standard MUTCD codes – I’m still working out how I’ll organize and group that section.
I also haven’t revised the section on recreational and cultural interest signs, for two reasons: one, FHWA has not yet released the official layouts for these signs (yes, I know Caltrans has developed some layouts, but they’re not “FHWA-official”). Also, there is a possibility this section may be dropped from the next edition of the MUTCD – we’ll see when the draft MUTCD is released (any time soon…) 🙂
Anyway, I’m happy with how it’s turned out so far. As always, feedback (preferably positive) is always welcome.
Enjoy!
Wheely Useful
Another Manual of Traffic Signs update to announce: as of late last night, the Bicycle Facility Signs section of the website is updated.
Roll on over to:
http://www.trafficsign.us/bikesign.html
And don’t forget, many of the PDF versions of the signs on the website are user-editable, in case you need a bicycle guide sign with your particular wording on it.
Also, the D series section of guide signs is getting close to halfway finished, with D1-D4 and D10-11 series complete. Progress rumbles along…
PNGie-Wingie
Since the Manual of Traffic Signs site was inaugurated as the first major website devoted to US road and highway signing back in 1996, I’ve used .gif format files for many of the sign images, as that format renders simple color images very well and offers high compression with zero loss.
However, as time has wandered onward, the .gif file format has become somewhat of a niche item, now used mostly for self-playing animations. All browsers still support rendering of .gifs, but some websites (I’m looking at you, Facebook) assume that all .gif files are movie files and can’t handle simple viewing and uploading without screwups.
But what finally moved me to belated action is my current work on D series guide signs (note: don’t bother looking – nothing new is posted yet for Ds – coming soon in due time). When I’ve been creating the large bitmap graphics for the D1s, I just can’t get smaller white on green text to look right in a 256-color palette, but it looks fine when exported as a 32-bit .png file.
But my OCD won’t allow me to have just the D series sign bitmaps in .png format and all the rest in .gif. Nope, just won’t do.
So, thanks to the twin miracles of batch conversion in Graphic Converter and fast find/replace in the HTML files, I’ve updated all the recently-revised sign pages to now use .png files for the big bitmaps. This shouldn’t affect the viewing experience, except that some browsers may render the 32-bit files with less jaggieness (yay).
But… I’m still keeping all the small sign thumbnail images (50 x 50, 100 x 100) in .gif format. Because quite a few of those are indeed animated, and I don’t want to ruin the fun.
Hoping for no bugs, and enjoy the new graphics.
Full of Sheet(ing)
The Manual of Traffic Signs webpage on retroreflective sign sheeting is now updated. You can reflect on it at:
http://www.trafficsign.us/signsheet.html
Special thanks to Seth Chalmers, Gene Hawkins, and Paul Carlson for their help in revising this page.
Back To School
It’s almost time (at least here in sunny Arizona) for the kids to be herded back into the classrooms and begin another year of brilliant scholarship (or something like that). And just in time, the School Signs section of the website has been updated. Take a look at all the fluorescent-yellow-green goodness:

Warning Signs Are Complete! And TTC Too!!
Another major achievement to announce.
The entire section on warning signs is finally complete and revamped, from the W1-1 to the W25-2. Several months of work have resulted in greatly-improved webpages, fully updated to 2009 MUTCD compliance and including user-editable PDFs for signs with user-adjustable legends. And don’t forget the “Create Your Own Warning Sign” section, too – now with four different background colors to choose from!
And since the warning sign section is now complete, I realized that if I quickly knocked out the G20 series and a few E5 signs that I could also complete the Temporary Traffic Control Signs section as well. So I did!
Much is going on around here, including a little bit of paying work, so I may be taking a break from the Manual for a bit. Once I get back to it, I’ll probably start in on school signs and emergency/incident signs, plus update some of the other information pages. Then comes the big unfinished sections on guide signs – first the Ds, then the Es, then the recreational/cultural signs.
Lots of work still left to do. We’ll see how much of it gets done before the draft of the next MUTCD comes out!
Orange you glad that the W20s & W21s are done?
I’ve been busy the last few days…
Earlier this evening, I uploaded the revised W20 & W21 series signs for work zones. And like other sections of the Manual, the PDF files incorporating distances or other varying legend are set to be user-editable (In Acrobat or Acrobat Reader).
This means I’m nearly finished with the entire section on warning signs – in fact, I think I can see the (rotating, flashing, oscillating or strobe) light at the end of the section. 🙂
