# Transportation (non-FAA) Federal Register Final Rules (~2k NHTSA + FMCSA + FRA + PHMSA + STB + MARAD + FTA)

Every Department of Transportation Final Rule 1994-2026 excluding FAA (which has its own dedicated dataset of 22.9k Airworthiness Directives). NHTSA detailed Federal Motor Vehicle Safety Standards (FMVSS — seatbelts, airbags, child restraints, tire specs, school buses). FMCSA commercial motor carrier rules (hours of service, CDL standards, brake performance). FRA railroad safety (track standards, positive train control). PHMSA pipeline safety + hazardous materials shipping. MARAD merchant marine licensing. FTA mass transit. STB rail rates + mergers. Source: federalregister.gov/api/v1/documents.json (2 paginated multi-slug fetches per year — top 4 by volume in pass A, remaining 3 in pass B).
