From a public map listing (category “Car inspectors”) found through DuckDuckGo for “emissions testing”, seen Oct 7, 2026.

These are businesses whose public map listing (Apple Maps or Yelp data, found through DuckDuckGo) names inspections, emissions testing or smog checks. A listing is not proof that the business is certified by the Texas Department of Public Safety, and the list is not complete: confirm with the station or the DPS inspection station locator before you go.
