California's Clean Air Agency
CARB is charged with protecting the public from the harmful effects of air pollution and developing programs and actions to fight climate change. From requirements for clean cars and fuels to adopting innovative solutions to reduce greenhouse gas emissions, California has pioneered a range of effective approaches that have set the standard for effective air and climate programs for the nation, and the world.
CARB’s mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. CARB is the lead agency for climate change programs and oversees all air pollution control efforts in California to attain and maintain health-based air quality standards.
Mobile Smoke Check
California Mobile Smoke Check is comprised of CARB trained compliance testers and inspectors who have met regulatory requirements to be credentialed for the Clean Truck Check program, formerly known as “Heavy-Duty Inspection and Maintenance.”
Our staff are highly proficient in opacity measurements of diesel vehicles greater than 14,000 pounds using SAE’s stabilized J1667-201802 standard for instrumentation and describes the algorithm we use for the measurement and quantification of exhaust smoke produced during the test.
Our opacity test equipment is the same the government uses and conforms to SAE J1667 specifications under declaration of compliance with the CARB mobile source enforcement branch. By using the latest compliant test instruments utilizing the light extinction principle where a beam of light is attenuated by smoke through scattering and absorption, the analyzed data is measured to produce an accurate Clear Truck Check report for you and the state of California.

Truck Preconditioning
Your truck should be warmed-up under load for at least 15 minutes to ensure proper test conditions verified by water and oil temperature gauges.
Truck Safety Check
Your truck will be prepared for testing and includes a safety check. An inspection for exhaust leaks is performed to prevent erroneous test results.
Instrumentation Setup
Ambient air is measured and correction factors are generated. Calibration and correction factors are set per manufacturer's specifications and set-up procedures.
Execution & Validation
Execution of cycle testing is correlated to validation criteria for zero shift deviation values and 3-cycle average opacity and density. If criteria are not met, recheck previous steps and repeat test sequence.

Instrumentation Setup
Our VIC provides galvanic isolation between your truck and our computer and is established with proper protocol and driver. WAN network link is established. Vehicle and tester credentials are captured and entered.
Execution & Validation
CARB compliant Clean Truck Check HD I/M OBD scanner begins emissions data acquisition from truck. Data is formatted to create an encrypted snapshot that is uploaded to CARB for Pass/Fail data analysis.
It’s a pretty picture — green grass, shade trees, and a beautiful sunny blue sky with some wispy clouds. Best of all, the air is sparkling clean and fresh like after a rain shower. Absolutely perfect for a picnic to take in and enjoy California at its best!
California’s Air Resources Board “CARB” oversees all air pollution control efforts in California to attain and maintain health-based air quality standards. To that end, diesel trucks are required to comply with emission standards in order to haul freight. You need to have a Clean Truck Check twice a year to be in compliance.
