MUTCD 11th Edition + Signs

MUTCD 11th Edition — Current Standard + Searchable Sign Library

Built for traffic engineers, sign installers, work-zone designers, civil engineering students, and anyone responsible for traffic control. The current FHWA Manual on Uniform Traffic Control Devices (11th Edition, December 2023, with Revision 1 — December 2025) plus a searchable browser of 945 standard highway signs — not the 2009 edition still floating around other apps.

The full manual is free to read. A one-time $4.99 unlock adds the Sign Browser, full-manual search, and bookmarks.

No ads. No subscriptions. No data sharing. No account required. One optional one-time purchase.

FREE — COLOR & SHAPE REFERENCE
The conventions every traffic engineer should know cold: red = prohibition / stop, yellow = warning, orange = work zone, green = guide, blue = motorist services, brown = recreational, white = regulatory, fluorescent yellow-green = pedestrian/bike/school. Same for shapes: octagon = stop only, diamond = warning, pentagon = school, and the rest. Always at your thumb.

FREE — COMPLIANCE DATES
Curated list of MUTCD compliance dates from the FHWA Final Rule. Know exactly when each provision must be in place — useful for jurisdictions tracking transition obligations.
