Smog Check Requirements for 2000 & Newer Vehicles
Most vehicles model year 2000 and newer are tested using California’s OBD-II emissions system.
- On-board diagnostics (OBD-II) scan
- Emissions readiness monitor check
- Visual inspection of emissions components
- Functional testing where required
- Electronic submission to the DMV
OBD-II testing allows inspectors to identify emissions issues directly from your vehicle’s computer, often speeding up the inspection process.
Smog Check Requirements for 1996–1999 Vehicles
These vehicles fall into a transition period and may require both diagnostic and tailpipe testing.
- OBD-II diagnostics (where supported)
- Tailpipe emissions (sniffer) test
- Visual emissions system inspection
- Functional emissions checks
- DMV electronic reporting
Testing requirements depend on vehicle configuration and emissions equipment installed by the manufacturer.
Smog Check Requirements for 1995 & Older Vehicles
Older vehicles do not use onboard diagnostics and rely on tailpipe emissions testing.
- Tailpipe emissions (sniffer) test
- Visual inspection of emissions components
- Functional testing of emissions systems
- Verification of required equipment
- Electronic DMV submission
Because these vehicles lack computer diagnostics, proper maintenance is critical for passing emissions testing.
Heavy-Duty & Diesel Vehicle Smog Testing
Heavy-duty and diesel vehicles may follow different inspection standards under California emissions regulations.
- Smoke opacity testing (where required)
- Visual inspection of emissions controls
- Functional system checks
- Compliance verification
Requirements vary based on weight rating, fuel type, and model year. Contact us if you’re unsure which test applies.
