What Drives Us
Our Mission
Our goal is simple: make emissions testing and smog checks easier to understand and easier to complete. Every state has different inspection rules, model-year cutoffs, exemptions, and testing locations. Instead of digging through multiple DMV and agency websites, drivers can use one directory to:
- Check whether their vehicle needs an emissions test or smog check
- Understand state and county-level rules
- Find nearby certified testing stations by state and city
We're building a clear, consistent resource that saves time, reduces confusion, and helps drivers stay compliant with current regulations.
Our Services
What We Do
emissions-testing.com combines state rules with local station listings:
State Pages
Each state page summarizes current emissions testing requirements, including who must test, how often, which vehicles are exempt, and where testing is required.
City & Station Listings
Drivers can browse emissions testing and smog check locations by city, with addresses and contact details to confirm hours, pricing, and services.
Guides & Articles
Our guides explain how emissions testing works, how to prepare for a test, what happens if you fail, and how rules differ by vehicle type (gasoline, diesel, hybrid, electric).
This mix of rules + locations + how-to content is designed specifically around the real questions drivers search for every day.
Quality Assurance
How We Collect and Verify Listings
Our directory includes thousands of emissions testing and smog check stations across the United States. Listings are sourced from:
- Public regulatory and transportation data
- Business owners submitting their own stations
- Ongoing manual checks and updates
Before a station is marked as verified, we review basic details such as:
- Business name and address
- Contact information
- Service type (emissions testing, smog check, inspection services, etc.)
We also encourage station owners to keep their profiles up to date so drivers can rely on accurate information when planning a test.

Staying Current
How We Keep Information Updated
Emissions programs change over time as states update their Clean Air Act compliance plans, adjust county coverage, or modify model-year and fuel-type rules. We:
- Review official state and agency updates on a regular basis
- Update state pages when testing requirements, counties, or exemptions change
- Add new testing locations and remove closed stations as we confirm changes
Even with ongoing updates, rules can shift quickly. That's why we always recommend using our pages as a starting point and confirming final details with your local DMV or emissions program if you're unsure.
