US Regulatory Roadmap MUTCD + MASH + APL
Federal compliance is documentation, not approval. State APLs are the gate. Build once, use everywhere.
MUTCD 11th Edition effective Jan 18, 2024. All states required to adopt by Jan 18, 2026. Red/Yellow lens AFAD is explicitly defined in MUTCD Section 6E.
GUARDIAN requires no federal approval — only documented compliance.
Required documentation package (prepare once, use everywhere):
- MUTCD 6E conformance statement (signed by US PE-licensed traffic engineer)
- ITE VTCSH LED test report (NRTL-accredited lab — Intertek ETL or equivalent)
- MASH 2016 Category 4 crashworthiness analysis
- Operational manual (training requirements, site selection criteria per MUTCD)
- WZDx feed URL and FHWA registration confirmation
- AFADs approved in all 50 states
- Red/Yellow lens type explicitly defined
- Gate arm mandatory for R/Y signal types
- 8-foot minimum length (6L.04.04)
- 7-foot mounting height (6L.04.05)
- 4-inch R/W retroreflective sheeting (ASTM D4956 Type VIII)
- Breakaway joint for MASH compliance
WZDx (Work Zone Data Exchange)
Mandatory for federal-aid projects. GUARDIAN must output GeoJSON v4.2+ feeds. Register with FHWA.
BABA (Build America, Buy America)
>55% US component cost + final assembly in USA for federal funding eligibility. Phase 2 trigger.
California AB 759
Mandates positive protection including AFADs on state road projects. GUARDIAN is a direct response.
| Priority | State | Process | Timeline | Reciprocity |
|---|---|---|---|---|
| 1 | Minnesota (MnDOT) | Qualified Products List (QPL) | 60–90 days | IA, WI, ND adopt MnDOT QPL |
| 1 | Utah (UDOT) | Materials Acceptance & Qualification | 45–75 days | ID, NV, CO reciprocity |
| 2 | Virginia (VDOT) | Innovation Initiative fast-track | 90–120 days | National policy spillover |
| 2 | Texas (TxDOT) | Materials & Pavements Section | 90–120 days | Largest single US AFAD market |
| 3 | California (Caltrans) | APL Category 83 (Traffic Control) | 120–180 days | AB 759 mandate = strong demand |
Submit same documentation package to all. Prepare once, use everywhere.
Why first: Leader in WZDx. MnDOT WZDx Import Engine auto-ingests Device Feeds.
Submit: Spec sheet + MUTCD conformance + ITE test report + MASH analysis
Contact: Materials/Traffic Engineering Division
Reciprocity: Iowa, Wisconsin, North Dakota
Why first: Strong "Smart Work Zone" focus. Streamlined approval.
Submit: Same documentation package as MN
Contact: Materials and Pavements
Reciprocity: Idaho, Nevada, Colorado
| AU Foundation | US MVP Swap | Reason |

Module: 8-inch (200mm) ITE-compliant LED module (e.g., GE DR4-VLA)
Intensity:
- Red: ≥165 cd (min)
- Yellow: ≥410 cd (min)
Per ITE VTCSH Table 1.
Aspects: 2-aspect Red/Yellow (MVP) or 3-aspect R/Y/G (Universal)
Testing cost: $15K–$30K USD, 30–60 days
Target: MASH 2016 Category 4 (Portable Device) via computer simulation analysis.
No physical crash test required for Category 4. Computer simulation accepted.
Required features:
- Magnetic breakaway joint
- Shear-bolt joint alternative
- Adjustable stability outriggers
- 80 mph wind rating
Analysis cost: $20K–$40K USD, 60–90 days
| Element | AU (MINIBOOM) | US (GUARDIAN) | Action |
|---|---|---|---|
| Signal head | AS 2144 | ITE VTCSH LED Circular Signal | ITE testing ($15–30K, 30–60 days) |
| Cellular | Quectel EC25-AU | Quectel EC25-AF | Module swap (confirm with Joel) |
| Crashworthiness | IP45/55 | MASH 2016 Cat 4 | Computer sim ($20–40K, 60–90 days) |
| Identity | TZ30 / MINIBOOM | GUARDIAN / Safe System | Brand rebuild — done |
| Data platform | TASTrack AU | TASTrack US + WZDx | Sam builds (60–90 days) |
Everything else (boom arm, LiFePO4, 77GHz radar, IoT processor, die-cast housing, GPS) is identical. Certification and branding exercise, not a redesign.
