Trucks operating in and out of the Cerritos Industrial Park, running loads toward the Port of Long Beach, or staging near the UPS hub on Moore Street don’t have room for a compliance gap. A lapsed Clean Truck Check certificate doesn’t just mean a fine it means a DMV registration hold, potential port access denial, and freight brokers who won’t dispatch you until your status clears. That’s lost revenue, not just a paperwork headache.
Western Cerritos sits in a state-designated high-risk air quality zone, and southeast Los Angeles County is one of the most actively monitored freight corridors in California. CARB isn’t softening enforcement here it’s intensifying it. The SR-91 and I-605 are exactly the kinds of high-volume diesel corridors where roadside emissions monitoring devices are deployed. If your truck gets flagged, you have 30 days to produce a passing test from a credentialed tester. We make sure you’re not scrambling when that notice arrives.
Getting compliant means your truck keeps moving, your port access stays open, and your registration clears without drama. For operators running multiple vehicles out of the Cerritos area, it also means building a reliable testing schedule into your calendar now because the requirement is semi-annual in 2025 and escalates to quarterly by October 2027.
We are a CARB-credentialed Clean Truck Check testing provider serving Los Angeles County including Cerritos and the surrounding Gateway Cities of southeast LA. Every tester on our team has completed CARB’s official HD I/M Tester Training Course, passed the required exam, and is listed on CARB’s publicly searchable database of credentialed testers. You can verify that before you ever call us.
This isn’t a general smog shop that added a new line to its menu. We were built specifically around the Clean Truck Check program the OBD-based compliance testing that applies to model year 2013 and newer diesel trucks with a GVWR over 14,000 pounds. That’s the only vehicle population we work with, which means every piece of equipment we use, every process we follow, and every test we run is purpose-built for exactly what CARB requires.
Operators in the Cerritos Industrial Park, drayage carriers running the I-605 south toward the Port of Long Beach, and contract carriers servicing the UPS regional hub this is the work we do, and we do it right the first time.
The Clean Truck Check process starts with confirming your truck qualifies model year 2013 or newer, diesel-powered, GVWR over 14,000 pounds. If that’s your vehicle, you’re in the right place. We schedule your test around your operation, not the other way around. For fleet operators in the Cerritos Industrial Park or carriers staging near the SR-91 and I-605 interchange, that means we work with your dispatch schedule, not against it.
On test day, we connect CARB-certified OBD testing equipment directly to your truck’s diagnostic port. This is not a generic scan tool it’s equipment that meets CARB’s specific technical requirements for the HD I/M program. The scan reads your truck’s onboard emissions data, checks for active fault codes, and verifies readiness monitors. The whole process is straightforward and doesn’t require you to take the truck off-route for long.
Once your truck passes, we submit the results directly to CARB’s CTC-VIS database electronically. You don’t touch the portal. You don’t upload anything. Your compliance certificate is generated immediately, your record is updated in CARB’s system, and your truck is cleared to operate. For fleet managers running five or ten vehicles out of the Cerritos area, that direct submission process isn’t a convenience it’s the difference between a manageable compliance calendar and a logistical nightmare.

The CARB Clean Truck Check applies specifically to diesel trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. If your truck is older than 2013 or lighter than that threshold, this program does not apply to you and we’ll tell you that upfront rather than waste your time. For the trucks that do qualify, the test uses OBD data to evaluate real-world emissions performance, not just a visual inspection or a tailpipe reading.
For Cerritos-area operators, the compliance stakes are particularly concrete. The Port of Long Beach roughly 8 to 10 miles southwest via I-605 and the I-405/710 interchange requires a valid Clean Truck Check compliance certificate for terminal entry. Freight brokers awarding loads to drayage carriers verify compliance status before dispatch. A truck without a current certificate gets turned away at the gate or passed over for the load. We handle the test, the submission, and the certificate generation so that gap never opens.
The annual CARB compliance fee is $31.18 per vehicle in 2025. Testing is currently required twice per year and escalates to four times per year by October 2027. If you’re managing a fleet of trucks operating in Los Angeles County whether they’re running the SR-91 through Cerritos, staging near the Auto Square corridor on Studebaker Road, or delivering into the Industrial Park off Bloomfield Avenue building a recurring testing relationship with a credentialed provider now is the move that keeps your operation running without interruption.
It depends on two things: the model year and the weight of your truck. The Clean Truck Check program applies to diesel-powered vehicles that are model year 2013 or newer and have a gross vehicle weight rating (GVWR) over 14,000 pounds. If your truck meets both of those criteria and operates on California public roads including routes through Cerritos on the SR-91, I-605, or I-5 then yes, it is subject to the program regardless of where the truck is registered.
This is a point that trips up a lot of out-of-state operators who run loads through the Cerritos corridor into the Port of Long Beach. California’s Clean Truck Check mandate applies to any qualifying truck operating on California roads, not just trucks registered here. If you’ve received a Notice to Submit to Testing or your truck was flagged by a roadside monitoring device on one of the freeways serving Cerritos, the 30-day deadline applies to you. We can get your truck tested and submitted to CARB’s system quickly so you’re not losing time or access.
As of 2025, the Clean Truck Check program requires semi-annual testing meaning your qualifying truck needs to pass two compliance tests per year, roughly every six months. That schedule is already more frequent than many operators expected when the program launched, and it’s not staying there. By October 2027, the requirement escalates to quarterly testing for most subject vehicles four passing tests per year.
For fleet operators running trucks out of the Cerritos Industrial Park or managing vehicles that regularly travel the SR-91 and I-605 corridors, that escalating schedule makes it worth establishing a consistent testing relationship now rather than scrambling to find a credentialed tester every time a deadline hits. We serve Los Angeles County and can work with your operational calendar to keep your fleet’s compliance current without disrupting your routes or dispatch schedule.
A failed test means your truck has active fault codes or unresolved emissions issues that prevented it from passing the OBD scan. The test itself doesn’t fix those issues that’s a separate repair process. What the test does is identify exactly what’s triggering the failure, which gives your mechanic a clear starting point rather than a guessing game.
Once the underlying issue is repaired, your truck needs to be retested. That’s where having a credentialed tester who can turn around a retest efficiently matters especially for operators in the Cerritos area who are running loads toward the Port of Long Beach and can’t afford extended downtime. In the meantime, a failed test does not generate a passing compliance certificate, and your truck remains out of compliance until it passes. If you’re operating under a Notice to Submit to Testing with a 30-day deadline, the clock doesn’t pause while repairs are underway. Getting the truck diagnosed and repaired quickly is critical.
We are a mobile-capable testing provider serving Los Angeles County, which includes Cerritos and the surrounding Gateway Cities. The OBD-based Clean Truck Check test doesn’t require a fixed shop location our CARB-certified testing equipment connects directly to your truck’s diagnostic port, which means the test can be performed at your yard, your fleet parking area, or wherever your trucks are staged.
For operators in the Cerritos Industrial Park, carriers staging near the SR-91 and I-605 interchange, or fleets parked near the UPS hub on Moore Street, on-location testing eliminates the need to route trucks to a shop and back which is a real operational cost when you’re managing multiple vehicles on active dispatch schedules. Contact us directly to confirm scheduling availability and service logistics for your specific location in the Cerritos area.
This is one of the most important questions you can ask and the fact that you’re asking it puts you ahead of a lot of operators who’ve paid for a test only to have the results rejected by CARB. California’s Clean Truck Check program requires that testing be performed by testers who have completed CARB’s official HD I/M Tester Training Course, passed the required exam with a minimum score of 80%, and are listed on CARB’s publicly searchable database of credentialed HD I/M testers.
That database is publicly available on CARB’s website, and you can search it before you book anyone. Our testers are on that list. If a provider you’re considering is not listed, their test results will not be accepted by CARB meaning you’ve spent money on a test that doesn’t count and still have an open compliance deadline. In a market like southeast Los Angeles County, where enforcement is active and the consequences of non-compliance are real, verifying the credential before you book is a five-minute step that can save you significant time and money.
Testing fees in the Southern California market generally range from around $95 to $150 per vehicle, depending on the provider and whether the service is mobile or shop-based. On top of that, CARB charges an annual compliance fee of $31.18 per vehicle in 2025 that’s paid directly to the state and is separate from the testing fee.
The more useful way to think about the cost is in context. Fines for CARB non-compliance can reach $10,000 per vehicle per day. A truck denied entry to the Port of Long Beach due to a lapsed compliance certificate loses a full load’s worth of revenue potentially several hundred to several thousand dollars depending on the haul. For fleet operators in the Cerritos area running multiple trucks toward the port on the I-605 corridor, the math on compliance versus non-compliance is not close. The testing fee is a small, predictable cost. The cost of letting it lapse is neither small nor predictable. We keep pricing transparent no surprise fees, no add-ons after the fact.
