State Standards & Libraries¶
TrafficCAD ships complete state manuals as first-class libraries — not overlays or patch lists. Pick the standard your agency reviews against and the catalog, templates, mounting rules, and citations all follow.

The Standard selector at the top of the symbol library switches the whole catalog between the national MUTCD and a state supplement.
The adopted standards¶
| Standard | Edition |
|---|---|
| National MUTCD (11th Edition) | MUTCD 11th Edition incl. Revision 1 (FHWA) |
| Texas MUTCD (2025) | Texas MUTCD, 2025 Edition (TxDOT) |
| California MUTCD (2026) | California MUTCD, 2026 Edition (Caltrans) |
Switch in the Symbol library's Standard dropdown (the hint below it confirms: "Signs shown are from the Texas MUTCD, 2025 Edition (TxDOT)."), or in the Sign Designer's top bar. The selection persists with the project.
What changes when you switch¶
- The sign catalog — browsing and search show only signs the selected manual publishes or adopts: the national set minus state-excluded signs, plus the state's own signs (TxDOT's CW-series work-zone codes, Caltrans' state signs). If a search has no state match, the panel offers the national library.
- Mounting rules and citations — height minimums, default post types, and the citation prefixes on every finding switch to the state manual: Texas' 7-ft-everywhere rule, California's sidewalk nuance. See Sign Mounting.
- The Sign Designer — panel styles, borders, and compliance checks cite the selected standard; a separate state layering select (National / California / Texas / Florida) drives materials and spec conventions on the fabrication sheet.
- Devices are universal — channelizing devices and plan symbols are common to all standards and never filter.
Working across jurisdictions¶
The standard is a per-project setting: a firm working Dallas on Monday and Sacramento on Tuesday keeps two projects, each showing its own catalog and citing its own manual. Signs already placed keep their artwork when the standard changes — the standard governs what the library offers and what the rules cite, not what's on your map.
More states
The national library covers every state that adopts the MUTCD without a full state manual. Texas and California ship today because they publish complete state editions; additional state libraries follow the same pattern.
