Florence-Graham sits at the edge of one of the most active freight corridors in the country. The I-110, Alameda Street, and the industrial yards in Vernon push heavy diesel traffic through this community every single day and CARB’s roadside REMD screening devices are active on those same routes. If your truck gets flagged, you have 30 days to submit a passing test before enforcement kicks in. That’s not a lot of runway when you’re running loads.
The real cost of ignoring Clean Truck Check compliance isn’t the $10,000-per-day fine it’s the DMV registration hold that shows up right when you need to renew, or the truck that gets pulled off the road mid-week. For owner-operators in Florence-Graham running tight margins on port drayage or Vernon distribution routes, that kind of disruption hits different than it does for a large fleet with backup vehicles.
What you get on the other side of a passing test is simple: your result goes into CARB’s CTC-VIS database, your compliant VIN transfers to DMV within 3 to 5 business days, and your truck is cleared to operate. No gray area, no guessing. You can verify your own status in the CTC-VIS system before your next registration renewal and know exactly where you stand.
We don’t test passenger cars, light trucks, or older vehicles that require opacity testing. The only trucks on our schedule are model year 2013 or newer, GVWR over 14,000 pounds the exact trucks that Clean Truck Check targets. That focus isn’t a limitation; it means every test is performed by someone who knows this regulation inside and out, not someone fitting you in between oil changes.
We’re CARB-credentialed and listed on CARB’s publicly available tester database at arb.ca.gov. You can look that up right now before booking anything and you should. Only credentialed testers using CARB-certified OBD equipment with an Executive Order number produce results that CARB will actually accept. We check both boxes.
Serving Los Angeles County means the trucks running out of Florence-Graham, the yards off Alameda Street, and the industrial operations neighboring Vernon are all within our service area. Our mobile model exists because that’s what this market needs a tester who comes to the truck, not the other way around.
You schedule the test and give us a location your yard, your dock, a lot near Florence Avenue, wherever the truck is parked. We come to you. There’s no repositioning the vehicle, no lost morning waiting at a testing facility, and no disruption to your dispatch schedule. For trucks running early shifts into Vernon’s industrial zone or heading south toward the port, that matters.
On-site, we perform the OBD test using CARB-certified equipment that carries an Executive Order number the only type of equipment that produces a valid compliance result. The test reads your truck’s onboard diagnostic system and checks for fault codes and emission system readiness. It typically takes less time than most people expect. If the truck passes, results are submitted electronically to CARB’s CTC-VIS system right then. You don’t log into any portal. You don’t fill out any forms. That step is handled entirely on your behalf.
One thing worth knowing: you can test up to 90 days before your compliance deadline. That means you don’t have to wait for a DMV notice or an NST to prompt you. Fleet managers running multiple trucks in the Florence-Graham and Vernon area can get ahead of the schedule entirely before peak delivery season, before a registration crunch, before the quarterly requirement kicks in starting October 2027.

Clean Truck Check applies to diesel and alternative-fuel heavy-duty vehicles that are model year 2013 or newer and carry a GVWR over 14,000 pounds. If your truck is older than 2013 or under that weight threshold, this program doesn’t apply and we won’t test it. That boundary matters because a lot of truck owners in the Florence-Graham area have received conflicting information about what the program covers, especially after the EPA SIP news in early 2026 created some confusion. To be clear: Clean Truck Check is still in full effect, and CARB has confirmed it.
Right now, OBD-equipped trucks are required to test twice per year. Starting October 1, 2027, that increases to four times per year. For owner-operators running one or two trucks out of Florence-Graham where the poverty rate sits around 20% and margins are already tight building a reliable testing relationship before that frequency doubles is a practical move, not just a compliance checkbox.
Florence-Graham is an unincorporated community in Los Angeles County, which means there’s no city government layering additional local ordinances on top of CARB’s state requirements. The compliance framework here is straightforward: meet CARB’s Clean Truck Check requirements, stay current in CTC-VIS, and your DMV record reflects it automatically. We handle the test and the submission. The rest takes care of itself.
If your truck is model year 2013 or newer and has a GVWR over 14,000 pounds, yes Clean Truck Check applies regardless of where in California you’re based, including Florence-Graham. The program covers nearly all heavy-duty diesel and alternative-fuel vehicles operating on California public roads, and that includes trucks registered in other states if they operate here regularly. Florence-Graham is unincorporated Los Angeles County territory, so there’s no separate city-level compliance requirement on top of CARB’s the state program is what governs.
If you’re unsure whether your specific truck qualifies, the GVWR is listed on the door placard or in your registration documents. Trucks under 14,001 pounds or older than 2013 are outside the scope of Clean Truck Check entirely, and we won’t test those vehicles. The program is specific, and so is our service.
CARB operates Remote Emissions Monitoring Devices REMDs along active freight corridors including the I-110 and surrounding routes that Florence-Graham truck operators use daily. If your truck is flagged as a potential high emitter, CARB will issue a Notice to Submit to Testing. From the date of that notice, you have 30 calendar days to submit a passing Clean Truck Check OBD result to CTC-VIS.
Thirty days sounds like enough time, but if you’re running a full schedule and haven’t lined up a credentialed tester yet, it goes fast. The important thing is not to confuse paying the annual CARB compliance fee which is $31.18 for 2025 with completing the actual emissions test. Those are two separate requirements. The fee doesn’t satisfy the test obligation. If you’ve received an NST, contact us as soon as possible so the test can be scheduled and submitted before the deadline.
This is one of the most common points of confusion among truck owners in the LA area. The $31.18 annual compliance fee indexed to California’s CPI is paid to CARB and registers your vehicle in the Clean Truck Check program. It does not replace the emissions test. These are two completely separate requirements, and paying the fee while skipping the test still leaves your truck non-compliant.
A lot of Florence-Graham truck owners have discovered this the hard way when DMV blocked their registration renewal. CARB transmits a list of compliant VINs to DMV nightly, so if your test isn’t on file, your registration status reflects that. The fix is straightforward schedule a test, pass it, and the CTC-VIS submission updates your record but it’s much easier to handle proactively than after a registration hold has already been placed.
Yes. Our entire model is built around coming to the truck not the other way around. If your truck is parked at a yard near Vernon, staged at a dock off Alameda Street, or sitting at a lot anywhere in the Florence-Graham area, that’s where the test happens. You don’t reposition the vehicle, you don’t lose time driving to a facility, and you don’t disrupt your morning dispatch.
For trucks running the Alameda corridor or servicing Vernon’s industrial operations, early-morning scheduling works well the test can be completed before the first load rolls out. We cover Los Angeles County, so the entire Florence-Graham and surrounding area is within our service zone. Just provide the location when you book and we come to you.
After a passing test result is submitted to CARB’s CTC-VIS database, CARB transmits your compliant VIN to DMV as part of its nightly data transfer. In most cases, your DMV record reflects the update within 3 to 5 business days. You can also log into your own CTC-VIS account to verify your compliance status directly you don’t have to wait for DMV to confirm it.
If you’re approaching a registration renewal deadline and need to confirm your status before the window closes, checking CTC-VIS directly is the fastest way to do it. We submit test results electronically at the time of testing, so there’s no delay on our end. Once the test is done and the result is in the system, the process moves on its own timeline without any additional steps required from you.
Currently, OBD-equipped heavy-duty trucks are required to test twice per year semi-annually. Beginning October 1, 2027, that increases to four times per year, or quarterly. For owner-operators in Florence-Graham running one or two trucks on tight margins, that’s a meaningful shift in the compliance calendar and the associated cost of testing.
The practical move is to establish a reliable testing relationship now, while the frequency is still twice a year, so the 2027 transition doesn’t catch you scrambling. Knowing your tester, knowing the process, and having your trucks’ compliance history in CTC-VIS already in order makes the move to quarterly testing a scheduling adjustment rather than a crisis. Our mobile model is built for exactly this kind of recurring compliance need we come to your location, the submission is handled, and you move on with your day.
