1. ⚡ OBD Periodic Testing (2013 Model Year & Newer)
This test is for heavy-duty diesel trucks, buses, and RVs equipped with a 2013 model year or newer engine.
What We Do: We connect a CARB-certified device to your vehicle's On-Board Diagnostics (OBD) port to check the emissions system status.
Key Benefit: Instant Results & Same-Day Compliance. Test results are uploaded to the CARB database immediately, allowing us to clear your DMV registration hold the same business day.
2. 💨 OVI Periodic Testing (2012 Model Year & Older)
This test is for heavy-duty trucks, buses, and RVs equipped with a 2012 model year or older engine.
What We Do: We perform the traditional Opacity (Smoke) test and a thorough Visual Inspection (OVI) of your engine's emissions control components.
Key Benefit: On-Site Convenience. We perform the required manual testing at your location, saving you travel time. (Note: CARB processing time for OVI results still takes several days.)
