Opacity Testing
I offer professional opacity testing for diesel trucks and motorhomes requiring compliance under California’s Clean Truck Check program. This test measures visible exhaust smoke levels to ensure your vehicle meets state emissions standards. Opacity test results are submitted directly to C.A.R.B. through my tester account and typically post within minutes.
Because opacity tests require additional paperwork and a more detailed process, the service is priced at $140.00. My mobile setup makes the process convenient and efficient, whether you're testing a single vehicle or an entire fleet.
