Every hour a truck sits idle is money you’re not making. That’s the real cost of non-compliance not just the fine, but the load you couldn’t run, the customer you had to call, the driver sitting in your yard waiting on a registration hold to clear. For fleet operators running routes out of the Cerritos Industrial Park or staging trucks near the SR-91 corridor, that kind of disruption isn’t theoretical. It happens.
CARB has had Roadside Emissions Monitoring Devices and license plate readers active on California roads since January 2023. The 91 and 605 freeways both cutting directly through Cerritos are among the most heavily screened freight routes in the state. If your truck gets flagged, you’ve got 30 days to submit a passing test or face fines that can reach $10,000 per vehicle per day, plus a DMV registration hold that CARB transmits nightly.
The fix isn’t complicated. A CARB-credentialed tester comes to your Cerritos location, runs the OBD data download on your 2013 or newer heavy-duty truck, and submits results directly to CARB’s CTC-VIS database before leaving. Your compliance status updates. Your truck keeps moving. That’s the outcome that actually matters.
We do one thing: Clean Truck Check OBD testing for heavy-duty trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. That’s it. No passenger cars, no light-duty smog checks, no general repair work on the side. Our entire operation every credential, every piece of equipment, every workflow is built around this one test type and this one class of vehicle.
Our CARB credentials are publicly listed at arb.ca.gov. You can look us up before you book. Every test we perform uses OBD devices that carry CARB Executive Orders the only equipment CARB legally accepts for valid compliance testing. Results go directly into CTC-VIS. You don’t touch the portal.
Cerritos sits at the intersection of three major California freeways and is home to one of LA County’s most concentrated industrial parks. Fleet operators working out of this city whether you’re running distribution routes on the 91, managing a logistics operation in the Industrial Park, or keeping commercial vehicles moving through Southeast Los Angeles County deserve a tester who actually understands the regulatory environment you’re operating in. That’s the only kind of service we offer.
You reach out, tell us where your truck is located whether that’s a yard off Alondra Boulevard, a fleet lot near Pioneer Boulevard, a dock in the Cerritos Industrial Park, or anywhere else in our service area and we schedule a time that works around your operation. Your truck doesn’t move. Your driver doesn’t lose a shift. We come to the vehicle.
When we arrive, we connect a CARB-certified OBD device to your truck’s diagnostic port. For model year 2013 and newer heavy-duty vehicles with a GVWR over 14,000 pounds, this is the test CARB requires under the Clean Truck Check program. The device reads your truck’s onboard emissions data, and the whole process typically takes a short amount of time per vehicle. If you have multiple trucks at the same location, we work through them efficiently so you’re not losing half a day waiting.
Once the test is complete, we submit your results directly into CARB’s CTC-VIS portal. You don’t log in. You don’t submit anything. CARB transmits compliant VINs to the DMV nightly, and your registration records update within 3 to 5 business days. If you’re working against a 30-day NST deadline or just want to test up to 90 days ahead of your compliance window we can move quickly. The process is the same either way.

The Clean Truck Check program applies to OBD-equipped heavy-duty vehicles that are model year 2013 or newer and have a GVWR over 14,000 pounds. If your truck doesn’t meet both of those criteria, this test doesn’t apply to you. We only test vehicles that fall within this specific class we don’t adapt a lighter-duty process and apply it here. Our equipment, credentials, and workflow are purpose-built for this test type.
For Cerritos-based operators, the compliance calendar matters more than most people realize. Right now, most OBD-equipped trucks test twice per year. Starting October 1, 2027, that increases to four times per year for OBD vehicles. If you’re running five trucks out of a facility in the Cerritos Industrial Park, that’s 20 tests per year instead of 10. Building a testing relationship now before the frequency doubles makes that transition significantly easier to manage.
The program also applies to out-of-state trucks operating on California roads. If you’re running loads through Cerritos from Nevada, Arizona, or anywhere else, CARB’s requirements follow the truck onto California roads regardless of where the plates were issued. The annual compliance fee is $31.18 per vehicle for 2025, but that fee doesn’t cover the emissions test the test is a separate requirement that catches a lot of operators off guard. We handle both the test and the direct CTC-VIS submission so there’s no gap in your compliance record.
If your truck is model year 2013 or newer and has a GVWR over 14,000 pounds, yes the Clean Truck Check program applies regardless of where in California you’re based or operating. The Cerritos Industrial Park is home to a significant concentration of logistics, distribution, and light manufacturing businesses, many of which operate exactly this class of vehicle. The program doesn’t make exceptions based on your industry or location within the state.
What matters for compliance is the vehicle itself: the model year, the GVWR, and whether it’s equipped with an OBD system. If your truck checks all three boxes, it needs to be tested semi-annually right now, with quarterly testing required starting October 1, 2027. We can come directly to your facility in the Industrial Park no repositioning, no trip to a testing station, no interruption to your operation.
CARB has deployed Roadside Emissions Monitoring Devices and Automated License Plate Readers on California roads since January 2023. These systems screen for high-emitting vehicles in real time, and the SR-91 and I-605 corridors both running directly through Cerritos are among the most actively monitored freight routes in Southern California. If your truck is flagged, CARB will issue a Notice to Submit to Testing.
Once you receive that notice, you have exactly 30 calendar days to submit a passing Clean Truck Check test. Missing that deadline doesn’t just mean a fine it means a DMV registration hold that CARB transmits nightly, which can prevent your truck from being legally operated until compliance is confirmed. We work with operators facing NST deadlines and can move quickly to get your test completed and submitted directly to CTC-VIS so your compliance record updates without delay.
This is one of the most common points of confusion in the entire program. The annual compliance fee $31.18 per vehicle in 2025 is a separate requirement from the emissions test. Paying the fee does not mean your truck has passed a Clean Truck Check. The OBD emissions test is a distinct step that has to be completed by a CARB-credentialed tester using certified equipment, and the results have to be submitted directly into CARB’s CTC-VIS portal.
Many truck owners in California including operators in Southeast Los Angeles County have paid the fee on time and assumed they were done, only to find a DMV registration hold waiting for them at renewal because the emissions test was never submitted. If you’re not sure whether your truck has a valid test on file, you can check your compliance status through CARB’s CTC-VIS system. If there’s a gap, we can get you tested and submitted before it becomes a bigger problem.
You don’t bring your truck anywhere. We’re fully mobile we come to your location in Cerritos or anywhere else in the Los Angeles County service area. Whether your trucks are parked at a yard, staged at a dock, or sitting in a lot off Studebaker Road or Norwalk Boulevard, we work around where they already are. There’s no fuel cost, no repositioning time, and no driver pulled off a route just to sit in a testing line.
The test itself involves connecting a CARB-certified OBD device to the truck’s diagnostic port and downloading the onboard emissions data. For a single vehicle, the process is typically quick. If you have multiple trucks at the same location, we work through them in sequence so you’re not losing a significant portion of your day. After testing, we submit results directly to CTC-VIS before we leave your location.
Yes. CARB’s Clean Truck Check requirements apply to any qualifying heavy-duty vehicle operating on California public roads the registration state doesn’t matter. If your truck is model year 2013 or newer, has a GVWR over 14,000 pounds, and is running loads through California, it’s subject to the same testing requirements as a California-registered truck.
Cerritos sits at the junction of SR-91, I-605, and I-5, making it a natural pass-through and staging point for trucks coming in from Nevada, Arizona, and other western states via the Inland Empire corridor. Out-of-state operators who aren’t aware of this requirement are among the most common recipients of CARB enforcement notices because the roadside monitoring systems on these corridors don’t distinguish between California plates and out-of-state plates. We test both California-registered and out-of-state vehicles. Compliance requirements are the same either way.
A standard smog shop that handles passenger cars and light-duty vehicles is licensed for a different type of testing than what Clean Truck Check requires. The HD I/M program which is what Clean Truck Check is requires a tester to hold specific CARB credentials for heavy-duty OBD inspection, and to use OBD devices that carry CARB Executive Orders. A shop that uses uncertified equipment, even professional-grade diagnostic tools, produces a test result that CARB will not accept. Your truck would still be flagged as non-compliant despite having gone through a test.
CARB publishes a public list of credentialed testers at arb.ca.gov. Before you book anyone for a Clean Truck Check in Cerritos or anywhere in Los Angeles County, it takes about two minutes to verify their credentials on that list. We’re on it. Beyond credentials, the difference with a specialist is operational: every process, every piece of equipment, and every submission workflow here is built specifically for 2013 and newer heavy-duty OBD trucks not borrowed from a lighter-duty operation and applied to a different vehicle class.
