Preferred sources
- Official state DMV or transportation agency pages.
- Official emissions or inspection program pages.
- Official county tax office or registration office pages when they define the rule.
Where PlateHarbor gets its data
PlateHarbor prefers primary state DMV, inspection program, and county office sources over third-party summaries.
How PlateHarbor presents them
- Public pages should link directly to the underlying official source.
- Structured records should preserve freshness metadata when available.
- When a source is ambiguous or incomplete, PlateHarbor should show that limitation instead of hiding it.
