    CARB-verified OBD test

    Visual inspection

Most covered trucks (over 14,000 lb GVWR, including out-of-state trucks driving in California) currently test twice a year. Under the original rule, OBD-equipped vehicles move to four tests per year from October 1, 2027. A bill has proposed cutting testing to once a year, so requirements may change. Always check your own deadlines in CARB’s CTC-VIS system. Open CTC-VIS Source: California Air Resources Board.

San Bernardino Clean Truck Check FAQ

Clean Truck Check in San Bernardino

You can get Clean Truck Check in San Bernardino without leaving your yard. We are a mobile tester: we drive to your terminal, distribution center, jobsite or home and run the test on site.

We test across the city, including the 92408 area near San Bernardino International Airport, the west side in 92410 and the northwest in 92411, plus yards along the I-215, the I-10 and the rail corridor. Whether you call it truck emissions testing or a truck smog check in San Bernardino, the test is set by the engine:

  • 2013 and newer diesel and 2018 and newer alternative-fuel: a CARB OBD test.
  • 2012 and older diesel without OBD: a diesel smoke test and visual inspection.
  • 2017 and older alternative-fuel without OBD: a visual inspection.

We explain the result plainly and give you the next due date. Call or text (858) 342-8328 or book online.

Cajon Pass trucks and the rest of San Bernardino County

Clean Truck Check in San Bernardino County means a lot of ground, from the valley floor to the High Desert. We cover it with on-site visits, and the quote reflects the location.

Many carriers here run the I-15 through the Cajon Pass every day. We can meet those trucks at the yard early, before they head up the hill, at locations in Devore, north San Bernardino or Muscoy. On the other side of the pass we test in Victorville, Hesperia and Apple Valley.

Closer in, we cover Grand Terrace, Colton, Highland, Loma Linda, Redlands, Mentone and Yucaipa, and west to Rialto and Fontana.

Trucks registered out of state that operate in California need testing too. Our guide on out-of-state trucks explains how that works. If a vehicle is an edge case, check CARB's rules for your vehicle or ask us.

Fleet emissions testing in San Bernardino

San Bernardino fleets can test every truck in one planned visit and then stay on a recurring schedule. A semi truck smog check for a whole yard is easier when the tester comes to you.

For fleet emissions testing in San Bernardino we provide:

  • Per-truck pricing for fleets.
  • Early-morning visits before dispatch.
  • Records per truck and VIN.
  • Reminders before each truck is due again.
  • Help with CTC-VIS questions and reporting.

If a truck fails, it needs repair and then a retest. Common causes are a check engine light, readiness monitors that are not set, DPF or emissions faults, and tampered or deleted equipment. We do not do repairs, but we explain exactly what the result means so your shop knows where to look. Read what to do after a failed test for the next steps.
