When a DMV registration hold hits, everything stops. Your truck can’t run legally, your loads don’t move, and the clock starts ticking the moment CARB flags your VIN. For owner-operators and fleet managers running routes on the I-10 and SR-60 two of the most active freight corridors cutting through Pomona and the surrounding region that kind of interruption isn’t just an inconvenience. It’s lost revenue with a hard deadline attached.
What most Pomona truck owners don’t realize until it’s too late is that paying the annual CARB compliance fee doesn’t complete your compliance. The OBD emissions test is a completely separate requirement. Plenty of operators in Pomona have paid that $31.18 fee, assumed they were good, and then hit a wall at DMV renewal. The test is what clears you and it has to be done by a CARB-credentialed tester using certified equipment.
That’s exactly what we do at All SMOG Motors. We come to your yard, your lot, or wherever your truck is parked in the Pomona area. We run the test, we submit the results directly to CARB’s CTC-VIS database, and your VIN shows compliant usually within 24 hours. No portal headaches, no paperwork to chase, no second trip anywhere.
All SMOG Motors is a CARB-credentialed heavy-duty OBD testing service covering Los Angeles County which means Pomona is squarely in our service area, not a stretch or an exception. We test one specific category of vehicle: model year 2013 or newer trucks with a GVWR over 14,000 pounds. That’s it. No passenger cars, no opacity tests on older trucks, no general smog work on the side. Just the Clean Truck Check program, done correctly, every time.
Our credentials are publicly listed on CARB’s official tester directory at arb.ca.gov you can verify that before you ever call us. We use only OBD testing devices that hold CARB Executive Order approval, which is the only equipment CARB actually accepts. A test run with uncertified equipment doesn’t count, and your truck is still non-compliant even if someone handed you a printout.
Pomona’s freight geography the SR-60 running right through the city, the warehouse yards off Valley Boulevard and Towne Avenue, the constant flow of trucks between the LA basin and the Inland Empire is exactly the kind of operating environment we built this service around. We understand the pressure on Pomona-based operators because we work with them every week.
You call or book online, tell us where your truck is located in the Pomona area, and we schedule a time that works around your operation not the other way around. Whether your truck is parked at a distribution yard near the I-10 corridor, staged at a Fairplex event load-in, or sitting at your own facility, we come to it. You don’t reposition the truck, you don’t lose a driver’s time, and you don’t burn fuel getting to a fixed location.
When we arrive, we connect our CARB-certified OBD testing device directly to your truck’s diagnostic port. The test reads the vehicle’s onboard emissions data this is the same data CARB’s roadside monitors are looking for when they scan trucks on California highways. The process is straightforward and doesn’t require the truck to be running at any special condition or load. For most trucks, the on-site portion takes a short amount of time.
Once the test is complete, we submit your results directly to CARB’s CTC-VIS database electronically. You don’t log into anything. CARB receives the data, your VIN updates to compliant status, and DMV records typically reflect that within three to five business days. If you received a Notice to Submit to Testing with a 30-day deadline, that clock stops the moment your passing test hits the system and we make sure it gets there.

The Clean Truck Check program applies to diesel, hybrid, and alternative-fuel heavy-duty vehicles that are model year 2013 or newer with a GVWR over 14,000 pounds. If your truck doesn’t meet both of those criteria the model year and the weight threshold it falls outside the scope of this program entirely. We only test vehicles that qualify under CARB’s HD I/M requirements, so if you’re not sure whether your truck is covered, just ask before you book.
Right now, most qualifying vehicles in Pomona and throughout Los Angeles County are required to test twice per year. Starting October 1, 2027, that frequency increases to four times per year quarterly for OBD-equipped trucks. For fleet operators running multiple vehicles out of Pomona-area yards, that’s a significant operational shift worth planning for now. Establishing a reliable testing relationship before that deadline makes the transition a lot smoother than scrambling when it hits.
Every test we perform includes direct electronic submission to CTC-VIS. There’s no add-on fee for that, no separate step you have to manage, and no risk of a submission error causing a compliance gap. Pomona falls within the South Coast AQMD jurisdiction one of the most actively enforced air quality districts in the country which means CARB’s enforcement posture in this corridor is serious. Getting tested by a verified, credentialed tester isn’t just good practice here. It’s the only version that actually counts.
It depends on two things: the model year and the weight rating. The Clean Truck Check program covers vehicles that are model year 2013 or newer and have a GVWR over 14,000 pounds. If your truck meets both of those criteria and it operates on California public roads including Pomona’s city-designated truck routes like Towne Avenue and Valley Boulevard, or the state highways running through the city then yes, it’s subject to CARB’s HD I/M testing requirements.
Where a lot of Pomona operators get tripped up is assuming the rule only applies to trucks registered in California. It doesn’t. If your truck is registered in another state but runs California routes regularly say, hauling freight in and out of the Pomona area on the I-10 or SR-60 CARB’s requirements still apply to you. Residency and registration state don’t create an exemption. The compliance obligation follows the vehicle’s operation, not its home state.
A Notice to Submit to Testing means CARB has flagged your vehicle as overdue for a Clean Truck Check, and you have exactly 30 calendar days from the date on that notice to submit a passing test. There’s no extension, no grace period, and no workaround. If you miss that window, CARB can transmit a non-compliant flag to DMV, which triggers a registration hold and at that point, your truck can’t legally operate until the hold is cleared.
The fastest way to resolve an NST is to get a mobile test scheduled immediately. We can come to wherever your truck is parked in the Pomona area, run the OBD test on-site, and submit the results to CTC-VIS the same day. Once your VIN shows compliant in CARB’s system, DMV records typically update within three to five business days. If you’re sitting on an NST right now, don’t wait the 30-day clock doesn’t pause while you’re figuring out next steps.
No and this is one of the most common and costly misunderstandings among truck owners in California. The annual compliance fee, currently $31.18 per vehicle, is a separate registration requirement. It does not substitute for the OBD emissions test, and paying it does not mark your truck as compliant in CARB’s system. You can pay the fee on time every year and still have a non-compliant VIN if the actual test hasn’t been submitted.
This catches a lot of Pomona operators off guard, especially owner-operators who manage their own compliance without a dedicated fleet administrator. If you’re unsure whether your truck has a passing test on file, you can check your vehicle’s status directly through the CTC-VIS portal using your VIN. If there’s no test on record or if the last test is past its valid window you need to schedule a new one before your next DMV registration renewal or before CARB issues a Notice to Submit to Testing.
The OBD test reads the emissions-related data that your truck’s onboard diagnostic system has already been collecting. A CARB-certified testing device connects to your truck’s diagnostic port, pulls that data, and evaluates it against CARB’s emissions thresholds. The truck doesn’t need to be driven, put on a dynamometer, or run under any special load conditions. It just needs to be accessible at your location.
For most qualifying trucks 2013 or newer, GVWR over 14,000 pounds the on-site portion of the test is relatively quick once we’re connected. The bigger time factor is usually just coordinating access to the vehicle. Because we’re a mobile service, we come to your yard, lot, or staging area anywhere in the Pomona area, which means you’re not burning driver time or fuel to get the truck somewhere. For fleet operators running multiple trucks out of a single Pomona facility, we can test several vehicles in a single visit, which keeps the operational disruption minimal.
A failed OBD test means your truck’s diagnostic system flagged one or more active emissions-related fault codes that exceeded CARB’s thresholds. The test result gets submitted to CTC-VIS regardless of pass or fail CARB receives the data either way. From there, you’ll need to have the underlying issue diagnosed and repaired by a qualified heavy-duty mechanic, and then retest once the repairs are complete.
The important thing to understand is that a failing result doesn’t extend your compliance deadline. If you’re working against a Notice to Submit to Testing deadline or an upcoming DMV registration renewal, the clock keeps running while repairs are in progress. Getting the truck looked at quickly and scheduling a retest as soon as it’s ready is the only way to stay ahead of it. We handle the testing side we don’t perform repairs but we can retest your truck in the Pomona area once your mechanic clears it, and we’ll resubmit the results to CTC-VIS the same day.
As of 2025, most OBD-equipped heavy-duty vehicles subject to CARB’s HD I/M program are required to test twice per year semi-annually. That applies to qualifying trucks operating in Pomona and throughout the rest of California. The testing schedule is tied to the vehicle’s registration cycle, so the specific months your truck is due will depend on when it was first enrolled in the program.
What’s worth knowing now is that the frequency is going up. Starting October 1, 2027, OBD-equipped vehicles will be required to test four times per year quarterly. For a single-truck owner-operator in Pomona, that’s a manageable shift. For a fleet manager running ten or fifteen trucks out of a warehouse yard near the SR-60 corridor, that’s a significant increase in testing volume that affects scheduling, budgeting, and operational planning. Pomona falls within the South Coast AQMD’s jurisdiction, where CARB enforcement is among the most active in the state, so staying ahead of that 2027 change rather than reacting to it is the smarter move for any operator running trucks in this area.
