New York emissions fail rates by county and town

Statewide, 4.6% of 8,634,588 initial emissions tests failed from Sep 2025 to Aug 2026. By county, the rate ran from 6.3% in Cattaraugus County down to 3.0% in Hamilton County. Counties are ranked by where the test happened (the station's county), not where the car is registered, and a high rate says as much about the age and condition of local vehicles as about the stations.
