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 $0.99 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 — THE FULL 11TH EDITION + REVISION 1
All 9 Parts, 83 Chapters, 837 Sections — the complete December 2025 text:
• Part 1 — General
• Part 2 — Signs
• Part 3 — Markings
• Part 4 — Highway Traffic Signals
• Part 5 — Low-Volume Roads
• Part 6 — Temporary Traffic Control
• Part 7 — Traffic Control for School Areas
• Part 8 — Railroad and Light Rail Transit Grade Crossings
• Part 9 — Bicycle Facilities
Every section preserves its Standard / Guidance / Support / Option structure exactly as published, with paragraph numbers preserved for cross-reference.
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.
REFERENCE TOOLS UNLOCK — $0.99 ONE-TIME
SIGN BROWSER
Grid view of every standard sign, filterable by category, shape, and color. Tap any sign to see its full spec page with the SVG rendering, MUTCD section reference, dimensions, and use cases. 945 signs indexed across all categories: R (Regulatory), W (Warning), D (Guide / Directional), E (Expressway Guide), M (Route Markers), OM (Object Marker), CD (School). Bundled vector SVG renderings for the actively-released 2024 SHS catalog — crisp at any zoom level.
SIGN CODE LOOKUP & MANUAL SEARCH
Type a sign code (R1-1, W11-2, D9-1) and jump straight to that sign — with one tap to the MUTCD section that governs it. Search the full manual text alongside the sign library. The fastest way to settle a "wait, is that a current sign?" debate in the field.
BOOKMARKS
Save any section or sign for one-tap access from anywhere — your own personal quick-reference list.
OFFLINE BY DESIGN
• Fully offline — works on a job site with no signal
• Dark, high-contrast interface for field use in bright sun
• Sign vector renderings stay crisp at any zoom
WHO IT'S FOR
• Traffic engineers and engineering technicians
• Sign installation crews and inspectors
• Work-zone designers and inspectors
• Municipal public works staff
• Civil engineering students preparing for the PE exam
• Anyone who needs to look up a sign code or compliance date on the job
