A DMV registration hold doesn’t just mean paperwork. It means a truck that can’t legally run loads and for small fleet operators on San Fernando Road, that’s lost revenue, not just an inconvenience. Getting your Clean Truck Check done before a hold appears is the difference between a 30-minute mobile visit and a compliance crisis you’re scrambling to fix.
San Fernando sits right at the I-5 and SR-118 interchange one of the busiest commercial freight corridors in Los Angeles County. That kind of daily volume doesn’t go unnoticed by CARB enforcement. If your 2013-or-newer diesel truck is operating on these roads with a GVWR over 14,000 pounds, it falls under the Heavy-Duty Inspection and Maintenance program, and compliance isn’t optional.
Once your test is done and submitted to CARB’s CTC-VIS database, DMV records typically update within 3 to 5 business days. No extra steps, no portal logins, no follow-up calls. The test is the last thing you have to do everything after that is automatic.
We don’t test passenger cars, older diesel trucks, or anything under 14,000 pounds GVWR. Our entire operation is built around one thing: OBD emissions testing for model year 2013 and newer heavy-duty vehicles under California’s Clean Truck Check program. That’s it. When you call, you’re not explaining what your truck is or what test you need you’re talking to someone who already knows.
We hold active CARB credentials, use only CARB-certified OBD equipment with verified Executive Orders, and submit results directly to CTC-VIS after every test. You can verify our credentials on CARB’s public tester list at arb.ca.gov before you book and you should.
San Fernando’s commercial corridor along San Fernando Road and the small fleet operators running construction materials, distribution, and trades work through Sylmar, Pacoima, and Mission Hills is exactly the market we were built to serve. Mobile service, direct submission, zero guesswork.
You call or book online, confirm your truck’s model year and GVWR, and pick a time that works for your yard. We come to your location in San Fernando whether that’s a commercial lot off San Fernando Road, a staging area near the I-5, or wherever your trucks are parked. Your vehicles don’t need to go anywhere.
On-site, a CARB-certified OBD device connects directly to your truck’s ECU and pulls the diagnostic data CARB requires. This isn’t a visual inspection or a smoke test it’s an electronic data download from the truck’s onboard system. The process typically takes around 30 minutes per vehicle, and your trucks can stay loaded, staged, or running on their normal schedule the same day.
Once the test is complete, we submit results electronically to CARB’s CTC-VIS portal right there on-site. There’s nothing for you to upload, log into, or submit afterward. If you’ve received a Notice to Submit to Testing, that 30-day window starts moving fast but with mobile service and same-day submission, you’re not burning days trying to schedule around a fixed location or figure out the portal on your own.

The Clean Truck Check applies to diesel and alternative-fuel heavy-duty vehicles with a GVWR over 14,000 pounds, model year 2013 or newer, operating on California public roads including trucks registered out of state. If your truck runs freight through the San Fernando Valley, crosses the Newhall Pass on the I-5, or makes daily deliveries through Los Angeles County, it’s subject to this program regardless of where it’s registered.
Right now, most OBD-equipped trucks are required to test twice per year. Starting October 1, 2027, that increases to four times per year. For a San Fernando fleet operator running five or six trucks, that’s the difference between ten annual tests and twenty. The annual CARB compliance fee is $31.18 per vehicle but that fee is separate from the emissions test itself. Paying the fee does not satisfy the testing requirement. Both are required.
We handle the OBD data download, use CARB-certified equipment with verified Executive Orders, and submit your results directly to CTC-VIS. There are no named service tiers here every vehicle gets the same credentialed process, the same certified equipment, and the same direct-to-CARB submission. Non-compliance penalties run up to $10,000 per vehicle per day, and CARB enforcement in the San Fernando Valley is active and documented. Getting ahead of your deadlines is always the better move.
If your truck is model year 2013 or newer, has a GVWR over 14,000 pounds, and operates on California public roads including the I-5, SR-118, or surface routes like San Fernando Road then yes, it’s subject to CARB’s Clean Truck Check program. This applies to diesel and alternative-fuel heavy-duty vehicles, and it applies whether your truck is registered in California or out of state. Operating in California is what triggers the requirement, not where the truck is titled.
San Fernando’s position at the I-5 and SR-118 interchange means trucks running through this corridor are operating on some of the most actively monitored commercial freight routes in the state. CARB has documented compliance enforcement activity specifically within the San Fernando Valley geographic zone. If you’re unsure whether your specific vehicle qualifies, the safest move is to confirm your model year and GVWR those two factors determine eligibility, and we can help you verify before you schedule anything.
A DMV registration hold tied to the Clean Truck Check program means CARB has flagged your vehicle as non-compliant either because a test hasn’t been submitted, or the vehicle isn’t registered in CTC-VIS. To clear it, you need a passing OBD test submitted to CARB’s CTC-VIS database by a credentialed tester. Once that submission goes through, CARB transmits compliant vehicle data to DMV nightly, and your registration records typically update within 3 to 5 business days.
For San Fernando fleet operators who discover a hold at renewal time, the urgency is real especially if that truck is running daily loads through the Valley or up the I-5 toward Santa Clarita and beyond. The hold doesn’t resolve itself with a fee payment or a phone call to DMV. The only path forward is a valid, submitted compliance test. We can come to your location in San Fernando, perform the OBD test, and submit results the same day so that clock starts immediately.
These are two completely separate requirements, and confusing them is one of the most common compliance mistakes San Fernando truck owners make. The annual CARB compliance fee currently $31.18 per vehicle in 2025 is a registration fee paid through CTC-VIS. It keeps your vehicle enrolled in the program. But it does not satisfy the emissions testing requirement. You still need a credentialed tester to perform the OBD data download and submit your results to CARB separately.
Think of it this way: the fee gets your vehicle into the system, and the test proves it’s actually running clean. Both are required. If you’ve paid the fee but never had a tester come out and perform the OBD test, your vehicle is still non-compliant in CARB’s records and that’s what triggers DMV holds and enforcement notices. If you’re unsure whether your test has been submitted, you can log into your CTC-VIS account and check your vehicle’s compliance status directly. We can also walk you through what you’re seeing if the portal isn’t making sense.
When CARB issues a Notice to Submit to Testing, you have exactly 30 calendar days to submit a passing test. That window moves fast especially if you’re running a small fleet out of San Fernando and can’t afford to have a truck sidelined or flagged during that period. The notice is not a warning to schedule something eventually. It’s a hard deadline with real consequences: non-compliance penalties can reach up to $10,000 per vehicle per day, and CARB has the authority to pursue DMV registration holds and off-road orders for vehicles that remain non-compliant.
The good news is that you don’t need to drive your truck anywhere. We come to your location in San Fernando, perform the OBD test on-site, and submit results to CTC-VIS the same day. If you’ve just received an NST and you’re working against that 30-day clock, calling sooner rather than later gives you the most flexibility on scheduling and gets your compliance status updated in CARB’s system before the deadline closes in.
Yes, and for fleet operators in San Fernando running multiple trucks, that’s exactly how most customers prefer to handle it. We come to your location and can test multiple vehicles during a single visit whether your trucks are staged at a yard off San Fernando Road, parked near the I-5 corridor, or spread across a commercial lot anywhere in Los Angeles County. Each OBD test takes roughly 30 minutes per vehicle, and your trucks stay exactly where they are throughout the process.
This also makes it easier to stay ahead of staggered compliance deadlines. CARB allows OBD tests to be submitted up to 90 days before a compliance deadline, so you don’t have to wait for a DMV renewal notice to start scheduling. Testing your full fleet in one visit before any holds appear is a much cleaner approach than handling each truck individually as deadlines arrive. And with the shift to quarterly testing coming in October 2027, establishing a reliable process now makes that transition significantly easier to manage.
It does. CARB’s Clean Truck Check program applies to any qualifying heavy-duty vehicle operating on California public roads the registration state doesn’t change the requirement. If your truck is model year 2013 or newer, has a GVWR over 14,000 pounds, and is running routes through San Fernando, Los Angeles County, or anywhere else in California, it falls under the program. Out-of-state operators are required to register in CTC-VIS, pay the annual compliance fee, and submit OBD test results just like California-registered vehicles.
This catches a lot of out-of-state fleet operators off guard, particularly those running freight through the I-5 corridor from Northern California or the Central Valley into the Los Angeles Basin. San Fernando sits right at the entry point of that southern run the Newhall Pass feeds directly into the city’s freeway interchange which means trucks coming through on a regular basis are operating in California frequently enough to trigger compliance requirements. If you’re not sure whether your operation qualifies, the determining factors are simple: model year, GVWR, and whether the truck runs on California roads. We can help you confirm before you schedule.
