CARB Testing & Clean Truck Check

Certified Clean Truck Check OBD testing done in-house, with the repairs handled in the same shop if you fail.

What to expect

Clean Truck Check is CARB's compliance program for diesel vehicles over 14,000 lbs GVWR operating on California public roads. It requires periodic emissions testing and annual reporting, and if you fall out of compliance the DMV will not renew your registration. For a working fleet that is not a paperwork problem, it is a parked truck.

We are a certified Clean Truck Check testing facility, so the test happens here — at the same shop that fixes whatever the test finds. That is the part most owners care about: if you fail somewhere else, you are towing the truck to a second shop.

Which test your truck needs depends on its engine year, and getting that wrong wastes you a trip. Call us with the VIN and we will tell you which one you need before you drive over.

  • ✓Engine year 2014 and NEWER — OBD test through the diagnostic port. This is the one we perform.
  • ✓Engine year 2013 and OLDER — the non-OBD (PSIP / smoke opacity) test. Call us before you drive over.
  • ✓Motorhomes — ONE test per year
  • ✓Not sure what is in your truck? Call with the VIN and we will tell you which test it needs

Straight Answers

CARB Testing & Clean Truck Check — common questions

How do I know which test my truck needs?

It goes by engine year. Engine year 2014 and newer takes the OBD test through the diagnostic port — that is the test we perform here. Engine year 2013 and older takes the non-OBD test instead. Either way, call with the VIN before you make the trip and we will tell you exactly where your vehicle stands.

How often does my motorhome need testing?

Motorhomes require one test per year. Trucks in the program are on a more frequent schedule — call us and we will tell you the schedule for your specific vehicle rather than a general rule.

Is CARB testing the same as Clean Truck Check?

For practical purposes, yes — people use both names for the same thing, which is why this is one page. Clean Truck Check is CARB's name for the program; the CARB test is what you come in for.

Do you handle the paperwork with the state?

Yes. We submit results to the state for you. The compliance fee itself is set by CARB and paid to the state, not to us.

What happens if I skip it?

Non-compliance puts a hold on your DMV registration. That is the expensive part — it is not a fine you can absorb and keep running. The truck stops being registerable until it is cleared.

Is this the same as my BIT inspection?

No, and running one does not satisfy the other. This is CARB emissions compliance. The 90-day BIT inspection is a CHP safety inspection and the annual DOT inspection is a federal safety requirement. Most commercial vehicles in California need all three on their own schedules.

Where We Work

CARB Testing & Clean Truck Check across East County and San Diego County

The shop is on Riverside Drive in Lakeside, so the tow is short from most of East County — and a short tow is real money on a truck that will not roll. We take work from across San Diego County.
