`pa_dmv_vehicle_registrations`

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

Count all vehicles registered in Pennsylvania by county for a given quarter, from PennDOT Driver & Vehicle Services. Covers the entire registered fleet of every fuel type, returns a genuine statewide Pennsylvania total plus each county’s share of it, and carries the plug-in count alongside for context. Answers “how many vehicles are registered in Pennsylvania”, “how many cars are registered in Allegheny County”, “which Pennsylvania county has the most registered vehicles”, and quarterly trend questions via the year and quarter arguments (2023 onward). For the electric and hybrid breakdown by drivetrain use pa_dmv_ev_adoption.
