`dmv_vehicle_registrations`

Pack: us-dmv · Endpoint: https://gateway.pipeworx.io/us-dmv/mcp

Registered vehicle counts from state DMV/motor-vehicle-agency data: how many vehicles are registered in a county, ZIP code or whole state, broken down by fuel type, make, model year or vehicle class. Covers California (fleet counts by ZIP, make, model year, fuel), New York (record-level fleet: county, ZIP, city, make, body type), Maryland (county fleet totals by month), Pennsylvania (county fleet totals by quarter), Delaware (statewide by fuel), Texas (statewide fiscal-year totals) and Washington (registration transactions per fiscal year or month by county, fuel and vehicle class). Answers questions like “how many vehicles are registered in ZIP 90210”, “which New York county has the most registered vehicles”, or “how many diesel registrations did King County WA process last year”. Every response reports its grain and as-of date, and whether the row list was truncated, because states publish at genuinely different levels of detail. For electric-vehicle counts and share use dmv_ev_adoption; for office addresses use dmv_offices.
