Certified Smoke Opacity Testing

Maintain Compliance with the CARB PSIP

The power of diesel engines is necessary for the logistics and construction industries. Unfortunately, diesel exhaust contains pollutants that affect air quality. CARB regulations exist to minimize this issue. Smoke opacity testing from Be CARB Compliant will help you meet the CARB inspection requirements for your fleet.

You Can’t Pass the PSIP Requirements Without a Certified Tester

The Periodic Smoke Inspection Program from CARB is meant to minimize pollutants in the California air. On-road fleets with at least two vehicles must undergo annual smoke opacity testing to remain in CARB compliance. Ignoring this regulation can result in hefty fines and registration holds.

Carrying out this test requires more than the purchase of a smoke meter. A professional must receive training through the California Council on Diesel Education and Technology to submit valid results to CARB. Results from testers who are uncertified or have an expired certification are invalid.

Be CARB Compliant has an in-house certified smoke opacity tester to handle your fleet PSIP testing needs. We will make certain your results are properly submitted and keep a digital record on file for your future compliance needs. We keep the compliance process simple!

Questions About Smoke Opacity Testing?

Below Are Some Common Questions about Diesel Emissions Testing

On-road fleets with two or more 6,000-lb diesel vehicles must receive annual smoke opacity testing. You are not required to test trucks with engines less than four years old.

CARB will only accept results from someone who has received official training. Any other results are invalid.

CARB gives you 45 days to make necessary repairs and bring your trucks into compliance. A retest is also required to verify the repair.

Emissions technology has changed over the past few years, and trucks with the latest equipment must meet a stringent 5% opacity limit. However, older trucks have more leeway, and a pre-1991 engine can pass by meeting a 40% opacity limit.

If you have a larger fleet, our tester will come to you. We will bring all the necessary equipment and paperwork for a proper inspection. Then, we will keep digital copies of your results on file for your convenience.
