The Port of Long Beach is roughly 10 miles from Artesia. For owner-operators and small fleet managers running loads out of Southeast LA County, that’s a short drive until your Clean Truck Check certificate lapses and you’re turned away at the gate. One missed compliance window can mean a full day of lost revenue, a freight broker who won’t rebook you, and a DMV registration hold that doesn’t clear itself.
That’s the real cost of putting this off. CARB’s Clean Truck Check program now requires covered trucks to test twice a year, with quarterly testing coming for most vehicles by October 2027. The trucks operating on the SR-91 and I-605 near Artesia are in one of the most actively monitored freight corridors in the state CARB uses roadside remote emissions monitoring devices along exactly these kinds of high-volume interchange routes. Getting flagged isn’t a hypothetical here. It’s a statistical reality for trucks running this corridor regularly.
When you’re compliant, you’re moving. No holds, no gate rejections, no scrambling to find a credentialed tester on a deadline. We handle the test and submit your results directly to CARB’s system so your certificate is on record not sitting in a portal waiting for you to figure out the upload.
We’re not a general smog shop that added a new service line. All SMOG Motors is a CARB-credentialed operation built specifically around heavy-duty diesel and alternative-fuel trucks model year 2013 and newer, GVWR over 14,000 pounds. That’s the only vehicle population we serve, which means every tester, every piece of equipment, and every process is dialed in for exactly the trucks CARB’s Clean Truck Check program covers.
Our testers have completed CARB’s official HD I/M Tester Training Course, passed the required exam, and appear on CARB’s publicly searchable database of credentialed testers. That’s not a marketing claim you can verify it yourself at the CARB website before you ever pick up the phone. The credential requires renewal every two years, which means it stays current or it doesn’t exist.
Serving the Gateway Cities corridor including Artesia and the surrounding Southeast LA County communities along the SR-91 and I-605 we understand the freight environment these trucks operate in and what it takes to keep them moving and compliant.
It starts with a call or booking. You give us the details on your truck year, make, GVWR and confirm it falls within the covered vehicle population: 2013 or newer, over 14,000 lbs. If it does, you’re in the right place. If it doesn’t, you’ll know immediately instead of wasting a trip.
On test day, a CARB-credentialed tester arrives with CARB-certified OBD testing equipment not a generic scanner, but the specific device class approved by CARB for HD I/M testing. The OBD scan reads your truck’s onboard diagnostic system and checks for active fault codes and readiness monitors that indicate how the emissions control systems are functioning. The test itself is straightforward and doesn’t require your truck to be taken apart or put on a lift. For Artesia-area operators staging near the SR-91/I-605 interchange or running loads toward Long Beach, the mobile format means you’re not pulling your truck off a route for a shop visit.
Once the test is complete, results are submitted electronically to CARB’s Clean Truck Check Vehicle Inspection System CTC-VIS immediately. You don’t log into a portal. You don’t upload anything. We handle the submission directly, and your compliance record is updated in CARB’s system the same day. If your truck passes, you’re done. If something flags during the scan, you’ll know exactly what it is and what needs to happen next before your 30-day window closes.

Every test we perform uses CARB-certified OBD testing equipment the specific device class required for results to be accepted in the CTC-VIS system. This matters because a test performed with non-approved equipment, even by a technically capable mechanic, will be rejected by CARB. That’s a situation Artesia-area operators have run into with general repair shops that aren’t set up for this specific program. When you book with us, the equipment is right, the credential is current, and the result counts.
We cover heavy-duty diesel and alternative-fuel trucks that are model year 2013 or newer with a GVWR over 14,000 pounds the exact vehicles California’s Clean Truck Check program targets. Lighter vehicles, older trucks, and passenger cars are outside the scope of this service. That focus is intentional. We don’t try to be everything to everyone, which means the testers working on your truck know this vehicle class and this program inside and out.
Direct submission to CARB’s CTC-VIS database is included with every test. For owner-operators running freight out of the Artesia and Southeast LA County area many of whom are managing their businesses without dedicated compliance staff that’s not a small thing. The annual CARB compliance fee of $31.18 is paid separately through your CTC-VIS account and is not part of the testing fee. If you’re unsure whether you’ve paid it or how to check, that’s a question worth asking when you call.
If your truck is a 2013 or newer diesel or alternative-fuel heavy-duty vehicle with a GVWR over 14,000 pounds and it operates on California roads, yes it’s subject to CARB’s Clean Truck Check requirements regardless of where it’s registered or based. Operating in Artesia, along the SR-91, or on the I-605 puts your truck in one of the most actively monitored freight corridors in the state. CARB deploys roadside remote emissions monitoring devices along high-volume routes like these, which means trucks in this area can be flagged as potential high emitters without being pulled over.
If you receive a Notice to Submit to Testing, you have 30 calendar days to submit a passing test result from a CARB-credentialed tester. Don’t wait until you get that letter. If your truck fits the criteria 2013 or newer, over 14,000 lbs and you’re not current on testing, the time to schedule is now.
As of 2025, covered trucks are required to pass two Clean Truck Check tests per year under California’s semi-annual testing schedule. That cadence is set to increase by October 2027, most vehicles will move to quarterly testing, meaning four tests per year. This isn’t a one-time compliance event. It’s an ongoing operational requirement, and the frequency is only going up.
For owner-operators and small fleet managers in the Artesia area, building this into your regular schedule now is a lot easier than scrambling when a DMV registration hold shows up or a freight broker flags your compliance status. Knowing your next test window and having a credentialed tester you can call makes the difference between a truck that keeps moving and one that doesn’t.
A failed test doesn’t automatically mean your truck is out of service, but it does mean you’re working against a clock. CARB gives you a window to make the necessary repairs and retest before enforcement consequences kick in. The most important thing you can do after a failed result is understand exactly what flagged which fault codes were active, which readiness monitors weren’t set so you can get the right repair done rather than guessing.
We submit your test results directly to CARB’s CTC-VIS system, so the record is accurate and current regardless of the outcome. If your truck doesn’t pass, you’ll know the specific reason immediately, which gives you the clearest possible starting point for getting it fixed. For Artesia-area operators with port access on the line or a DMV renewal coming up, that clarity matters more than a vague “it didn’t pass” conversation.
These are two separate charges, and confusing them is one of the most common reasons truck owners think they’re compliant when they’re not. The annual CARB compliance fee $31.18 per vehicle in 2025 is paid directly through your CTC-VIS account and goes to CARB. Paying that fee does not mean your truck has been tested. It’s more like a registration cost for being in the program.
The testing fee is what you pay a CARB-credentialed tester like us to perform the actual OBD scan and submit your results to CARB’s database. Both are required. A truck that has paid the annual fee but hasn’t submitted a passing test result from a credentialed tester is still non-compliant and still subject to DMV registration holds and penalties. If you’re not sure whether your CTC-VIS account is current on both, it’s worth checking before your next test window opens.
Yes. We serve Los Angeles County, which includes Artesia and the surrounding Southeast LA County communities Cerritos, Norwalk, Bellflower, and the broader Gateway Cities corridor. The mobile testing format means your truck doesn’t need to leave your yard, your staging area, or wherever it’s parked. For operators running freight between the Port of Long Beach and the Inland Empire via the SR-91 and I-605, that’s a practical advantage. Pulling a truck off a route for a shop visit has a real cost. On-site testing avoids that entirely.
When you call to schedule, confirm your truck’s location, year, and GVWR so the tester arrives with the right setup. CARB-certified OBD testing equipment is brought on-site, the scan is performed there, and results are submitted to CTC-VIS the same day. There’s no drop-off, no waiting room, and no follow-up submission on your end.
A Notice to Submit to Testing means CARB has flagged your vehicle most likely through roadside remote emissions monitoring as a potential high emitter. From the date on that notice, you have 30 calendar days to submit a passing test result from a CARB-credentialed tester. Missing that deadline means automatic DMV registration consequences and potential fines that can reach up to $10,000 per vehicle per day.
The 30-day window sounds reasonable until you factor in scheduling, any repairs that might be needed if the truck doesn’t pass on the first test, and retest time. Artesia’s position near the SR-91/I-605 interchange one of the most heavily monitored freight corridors in Southern California means trucks operating in this area are more likely to be captured by CARB’s roadside monitoring than trucks in less freight-intensive parts of the state. If you got a notice, call us, confirm your truck qualifies under the 2013-or-newer, over-14,000-lb criteria, and get on the schedule as soon as possible. The sooner the test is done and submitted, the more time you have to address anything that comes up.
