Smoke Opacity Test Oakland: J1667 Certified Testing
Looking for a smoke opacity test in Oakland? NorCal CARB Mobile provides SAE J1667 certified smoke opacity testing throughout Oakland and the East Bay. Our J1667 smoke opacity tests meet all California CARB Clean Truck Check requirements for diesel trucks manufactured in 2012 and older.
What Is the J1667 Smoke Opacity Test?
The SAE J1667 smoke opacity test is the CARB-required emissions test for older diesel trucks. It measures the opacity (darkness) of diesel exhaust smoke using a calibrated opacity meter. NorCal CARB Mobile uses a factory-calibrated Wager 6500+ opacity meter — the same professional-grade equipment required by the California Air Resources Board. We perform the full 3-sequence J1667 test protocol and issue your compliance certificate on the spot if you pass.
J1667 Smoke Opacity Test Price in Oakland
J1667 smoke opacity testing in Oakland is $250 per vehicle. This includes the full test, calibrated equipment, and same-day CARB compliance certificate. No hidden fees. Fleet discounts available for 2 or more vehicles.
Who Needs Smoke Opacity Testing?
Any diesel truck manufactured in model year 2012 or earlier operating in California requires a J1667 smoke opacity test for CARB Clean Truck Check compliance. This includes Oakland port drayage trucks, construction and contractor vehicles, delivery fleets with older equipment, and interstate carriers with pre-2013 vehicles.
Oakland Smoke Opacity Testing Service Area
We provide mobile J1667 smoke opacity testing at your Oakland location — your warehouse, yard, truck stop, or job site. Service available throughout Oakland, Berkeley, Emeryville, San Leandro, Alameda, and all Alameda County communities. Schedule your Oakland smoke opacity test today: call 916-890-4427 or text (415) 900-8563.
