Culver City moves fast. Amazon’s campus is expanding. Sony Pictures and the production companies around it run on tight schedules. Construction crews are working across the Hayden Tract and Ivy Station. Every one of those job sites depends on trucks that are legally cleared to operate and if yours isn’t CARB compliant, it doesn’t matter how good your work is. You’re not getting through the gate.
California’s Clean Truck Check program requires heavy-duty vehicles that are model year 2013 or newer with a GVWR over 14,000 pounds to pass a credentialed OBD emissions test on a semi-annual basis twice a year right now, escalating to four times a year by October 2027. That’s not a distant deadline. It’s a compliance cycle that’s already running, and if your registration is on hold or you’ve received a Notice to Submit to Testing, you have 30 calendar days to produce a passing result from a CARB-credentialed tester.
What changes when your truck is fully compliant? You show up. You work. Your registration clears. Your freight broker, your general contractor, or your studio client gets the certificate they need from you, and the job moves forward. That’s the outcome not a piece of paper, but uninterrupted access to the work that pays you.
All SMOG Motors is a CARB-credentialed Clean Truck Check testing provider serving Los Angeles County, including Culver City and the surrounding Westside corridor. Every tester on our team has completed CARB’s official HD I/M Tester Training Course, passed the state exam, and is listed on CARB’s publicly searchable database of credentialed testers. That’s not a marketing claim it’s a state-issued authorization you can look up before you ever call us.
We work exclusively with model year 2013 or newer heavy-duty vehicles with a GVWR over 14,000 pounds. That’s the exact population the Clean Truck Check program covers, and it’s all we do. No passenger cars, no lighter vehicles, no guesswork about whether your truck qualifies. We use CARB-certified OBD testing equipment on every test, and we submit your results directly and electronically to CARB’s CTC-VIS database the moment the scan is complete.
If you’re running trucks in and around Culver City on the I-405, off the I-10 at Robertson, into a production lot or a construction site we know this territory, and we know what’s at stake for your operation.
It starts with a call or an online booking. You tell us where your truck is a job site in the Hayden Tract, a staging yard near the I-405, a lot off Washington Boulevard and we schedule a time that works for your operation. You don’t need to drive across Los Angeles to find a testing facility. We come to you.
When we arrive, we connect our CARB-certified OBD testing device directly to your vehicle’s onboard diagnostic system. For model year 2013 and newer heavy-duty trucks, this is the testing method CARB requires not a tailpipe probe, not a visual inspection, but a direct electronic read of your truck’s emissions-related systems. The scan itself doesn’t take long. What matters is that it’s done with the right equipment by a tester with the right credential, because those are the two things CARB actually checks before accepting a result.
Once the test is complete, we submit your results directly to CARB’s Clean Truck Check Vehicle Inspection System CTC-VIS electronically and immediately. You don’t log into a portal. You don’t upload anything. Your compliance record updates in real time. If your truck passes, your certificate is on record. If something flags during the scan, we’ll walk you through exactly what it means and what your next step is no vague answers, no runaround.

The CARB Clean Truck Check applies to any heavy-duty vehicle that is model year 2013 or newer with a GVWR over 14,000 pounds and operates on California public roads. That includes trucks registered in other states if your vehicle is running loads in Culver City, making deliveries to a studio lot, or hauling materials to a construction site off Jefferson Boulevard, California’s requirement applies to you regardless of where your plates are from.
The test itself is OBD-based. We plug into your vehicle’s diagnostic port, run the CARB-required scan using certified equipment, and read the emissions-related data your truck’s own systems have been collecting. This is not the same process as a standard passenger car smog check and none of the smog stations on Washington Boulevard near the Culver City DMV are equipped or credentialed to perform it. If you’ve already called one of those shops and been turned away, that’s exactly why this service exists.
The annual CARB compliance fee is $31.18 per vehicle for 2025 that’s a separate charge paid directly to the state, and it’s distinct from the cost of the test itself. Both are required. Testing is currently required twice per year, and that frequency increases to four times per year by October 2027. For fleets operating in Los Angeles County whether you’re running construction equipment through Culver City’s ongoing development boom or managing logistics for one of the tech campuses along the Silicon Beach corridor building a consistent testing schedule now is the move that keeps you ahead of enforcement.
If your truck is model year 2013 or newer and has a GVWR over 14,000 pounds, yes it needs to be tested under California’s Clean Truck Check program, regardless of what it’s being used for or where it’s registered. Construction vehicles, dump trucks, flatbeds, concrete mixers, and equipment haulers all fall within the program’s scope if they meet those two criteria and operate on California public roads.
Culver City is in the middle of a significant construction cycle right now Amazon’s campus expansion, Apple’s content production facilities, the ongoing Ivy Station development, and numerous smaller commercial builds are all generating sustained heavy-duty truck traffic in the city. If you’re a contractor or subcontractor with trucks on any of these sites, CARB compliance isn’t optional. A DMV registration hold on any one of those vehicles means it can’t legally operate and that means it’s not on your Culver City job site.
A Notice to Submit to Testing an NST means CARB has flagged your vehicle as a potential high emitter, typically through a roadside emissions monitoring device. The I-405 and I-10, both of which run directly through or along the edge of Culver City, are among the most heavily monitored freight corridors in the state. If your truck was flagged in this area, the NST clock starts from the date on the letter.
You have exactly 30 calendar days from that date to submit a passing emissions compliance test performed by a CARB-credentialed tester. That’s not a grace period it’s an enforcement deadline. If you miss it, you’re looking at DMV registration consequences and potential fines that can reach up to $10,000 per vehicle per day. The moment you receive that letter, schedule your test. Don’t wait to see if it resolves on its own, because it won’t.
No and this is one of the most common points of confusion for truck operators in Culver City. The smog check stations on Washington Boulevard near the Culver City DMV are licensed for passenger vehicle emissions testing. They use tailpipe probes and visual inspection processes designed for cars and light trucks. They are not equipped with CARB-certified OBD testing devices, and their testers do not hold the HD I/M credential required to perform a Clean Truck Check. If you call one of those shops about your heavy-duty commercial vehicle, they won’t be able to help you.
The Clean Truck Check is an entirely separate program, administered by the California Air Resources Board, requiring a different credential, different equipment, and a different submission process. All SMOG Motors holds the CARB-issued HD I/M tester credential specifically for this program covering model year 2013 and newer heavy-duty vehicles with a GVWR over 14,000 pounds. It’s a completely different service from a standard smog check, and the two are not interchangeable.
Yes. California’s Clean Truck Check requirement applies based on where the vehicle operates, not where it’s registered. If your truck is model year 2013 or newer with a GVWR over 14,000 pounds and it drives on California public roads including making deliveries to Culver City’s studio lots, tech campuses, or construction sites it is subject to the Clean Truck Check program.
This catches a lot of out-of-state operators off guard, particularly those running loads into the Los Angeles basin from Nevada, Arizona, or other western states. If you’re delivering equipment to a production company in Culver City, hauling materials to a job site near the I-405, or making regular runs through Los Angeles County, you need to be registered in CARB’s CTC-VIS system and you need to have a current passing test on record. The exemption many people assume exists for out-of-state vehicles simply does not apply here.
As of 2025, the Clean Truck Check program requires semi-annual testing meaning your truck needs to pass a credentialed OBD emissions test twice per year, roughly every six months. That frequency is tied to your vehicle’s DMV registration renewal cycle, so the specific months will vary depending on your registration date.
What’s important to plan for now is the upcoming change: by October 2027, testing frequency increases to quarterly four times per year for most vehicles in the program. If you’re operating a fleet of heavy-duty trucks in Los Angeles County, that’s a significant compliance calendar shift. Building a relationship with a credentialed tester now, before that escalation hits, means you’re not scrambling to find availability four times a year under deadline pressure. For Culver City operators running trucks across the Westside and into the broader LA basin, getting ahead of that schedule is the practical move.
There are two separate costs involved, and understanding the difference matters. The first is the annual CARB compliance fee, which is $31.18 per vehicle for 2025. That fee is paid directly to the California Air Resources Board and is adjusted each year based on the California Consumer Price Index. It covers your vehicle’s enrollment and registration in the CTC-VIS system it does not cover the cost of the actual test.
The second cost is the tester’s service charge, which is what you pay All SMOG Motors to perform the OBD scan, use CARB-certified equipment, and submit your results directly to CARB’s database. These are two distinct transactions. Both are required. For Culver City fleet operators whether you’re managing construction vehicles across multiple job sites or running a small fleet of delivery trucks serving the tech campuses along the Silicon Beach corridor knowing this upfront prevents surprises after the test is done. If you want a clear quote before you schedule, call us and we’ll give you a straight number.
