A Notice to Submit to Testing from CARB gives you 30 days. That window closes fast when you’re running freight between the Inland Empire and the Ports of Los Angeles and Long Beach and it closes even faster when you can’t find a credentialed tester who actually serves La Verne and the eastern San Gabriel Valley. Getting ahead of the deadline means your truck stays on the road, your registration stays clean, and your freight contracts stay intact.
La Verne sits at the junction of SR-210, I-10, and SR-57 three of the most actively monitored freight corridors in Southern California. CARB deploys remote emissions monitoring devices along these routes, and a non-compliant truck doesn’t have to be pulled over to get flagged. It can happen on a routine run. For operators staging out of the business parks near Brackett Field or making regular runs to Ontario International Airport less than 20 minutes away that’s a real exposure every time the truck moves.
The Pomona Valley’s basin geography traps diesel particulate matter in a way that flat corridors don’t. That’s part of why the South Coast AQMD one of the most active air quality enforcement districts in the country covers this region. Staying CARB compliant in La Verne isn’t just about avoiding fines. It’s about operating in an area where the regulatory environment is serious, consistent, and not going away.
We are a CARB-credentialed Clean Truck Check testing provider serving Los Angeles County and Riverside County which means the SR-210 corridor, the Pomona Valley, and the freight network surrounding Ontario International Airport are all within our service area. This isn’t a general smog shop that added a new service line. Every test we perform is specifically for the vehicle population CARB’s program targets: model year 2013 or newer diesel and alternative-fuel trucks with a GVWR over 14,000 pounds.
Our testers have completed CARB’s official HD I/M Tester Training and appear on CARB’s publicly searchable database of credentialed testers. You can verify that before you call and we encourage you to. We use CARB-certified OBD testing equipment, not generic diagnostic tools, and we submit results directly to California’s CTC-VIS system the moment the test is complete. No portal navigation on your end. No paperwork delays. The compliance record exists the second we finish the scan.
It starts with a quick call or booking to confirm your truck qualifies model year 2013 or newer, GVWR over 14,000 pounds. If you’re not sure whether your truck falls under California’s Clean Truck Check requirements, we can help you figure that out before you schedule anything. A lot of operators running routes through La Verne on SR-210 or staging freight near Brackett Field don’t realize the requirement applies to out-of-state registered trucks too if it’s operating on California roads, it needs to be compliant.
Once you’re scheduled, we connect your truck’s OBD port to our CARB-certified testing device. This is not a visual inspection or a tailpipe test it’s a direct read of your truck’s onboard diagnostic system, which is what CARB requires for 2013 and newer vehicles. The scan itself is straightforward and doesn’t take long. What matters is that the equipment is approved and the tester is credentialed, because results from non-approved equipment are rejected by CARB outright.
After the test, we submit your results electronically to CARB’s CTC-VIS database directly, in real time. You don’t log into a portal, you don’t upload anything, and you don’t have to wonder if the submission went through. If your truck passes, your compliance record is updated immediately. If there’s an issue, we’ll walk you through what it means and what comes next. Semi-annual testing is already in effect for 2025, and quarterly testing kicks in for most trucks by October 2027 so this process is one you’ll want to have dialed in with someone you trust.
Ready to get started?
California’s Clean Truck Check formally the Heavy-Duty Vehicle Inspection and Maintenance program applies to diesel and alternative-fuel trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. If your truck doesn’t meet both of those criteria, this program doesn’t apply to you. That’s worth stating clearly, because there’s a lot of confusion in the market about what’s actually required and for whom.
For trucks that do qualify, compliance involves two things: an annual registration fee paid through CARB’s CTC-VIS system ($31.18 per vehicle in 2025, adjusted each year), and OBD-based emissions testing performed by a CARB-credentialed tester using approved equipment. The testing frequency is now semi-annual twice per year and will increase to quarterly for most trucks by October 2027. For operators running freight through the I-10 and SR-210 corridors that run through and around La Verne, that cadence is already a recurring operational reality.
What you get from us is the test itself, performed with CARB-certified OBD equipment, plus direct electronic submission of your results to CTC-VIS. There’s no additional step on your end after the test is done. For fleet operators managing multiple trucks out of locations like San Polo Business Park or the La Verne Business Park near Brackett Field, we can work through vehicles on a schedule so compliance doesn’t become a scramble every six months. The goal is straightforward: keep your trucks legal, your registration clear, and your freight access uninterrupted.
Yes California’s Clean Truck Check requirement applies based on where the truck operates, not where it’s registered. If your truck is model year 2013 or newer, has a GVWR over 14,000 pounds, and it’s operating on California public roads, it falls under this program regardless of whether it’s registered in Arizona, Nevada, or any other state. This catches a lot of operators off guard, especially those running regular loads into the Inland Empire or through the Pomona Valley on I-10 or SR-210.
CARB deploys remote emissions monitoring devices along major freight corridors in Southern California including the routes that run directly through and around La Verne. A non-compliant truck can be flagged by one of these devices during a normal run without ever being pulled over. Once flagged, you’ll receive a Notice to Submit to Testing with a 30-day window to get a passing test from a credentialed tester. Getting compliant before that happens is a much easier situation to be in.
A failed test doesn’t immediately result in fines, but it does start a clock. CARB will typically issue a Notice to Submit to Testing or place a hold on your DMV registration, depending on the circumstances. From that point, you have a defined window to address the underlying emissions issue and submit a passing test result. The key is not letting that window expire because once it does, the penalties escalate quickly. Non-compliance fines can reach up to $10,000 per vehicle per day, and that’s not a theoretical ceiling.
For operators in the La Verne area running freight through the SR-210 and I-10 corridors, a registration hold or compliance flag doesn’t just affect one truck it can affect your ability to access port facilities in Los Angeles and Long Beach, and freight brokers routinely verify compliance status before awarding loads. If your truck fails, the first step is understanding what triggered the failure. We’ll tell you exactly what the test result showed and what it means for your next steps, so you’re not left guessing.
As of 2025, qualifying trucks model year 2013 or newer with a GVWR over 14,000 pounds are required to test twice per year under California’s Clean Truck Check program. That’s the current semi-annual requirement, and it’s already in full effect. By October 2027, most trucks in this program will be required to test quarterly, meaning four times per year. If you’re operating in Los Angeles County, which La Verne falls under, the South Coast AQMD’s enforcement environment means these deadlines are taken seriously.
The practical implication for fleet operators or owner-operators running trucks out of the Pomona Valley is that compliance testing is no longer an annual checkbox it’s a recurring operational task. Building a relationship with a credentialed tester now, before the quarterly requirement kicks in, is the smarter play. It means you’re not scrambling to find someone every few months, and your compliance record stays current without gaps that could trigger a DMV hold or freight access issue.
They’re completely different programs targeting completely different vehicles. A standard smog check the kind you get at a licensed smog station for a passenger car or light truck is a visual and tailpipe-based inspection program administered through the Bureau of Automotive Repair. California’s Clean Truck Check is a separate CARB program specifically for heavy-duty diesel and alternative-fuel vehicles that are model year 2013 or newer with a GVWR over 14,000 pounds. It uses OBD scanning technology a direct read of the truck’s onboard diagnostic system not a tailpipe test.
The equipment required is different, the credentials required are different, and the results go to a completely separate state database called CTC-VIS. A standard smog station cannot perform a Clean Truck Check unless they have CARB-credentialed testers and CARB-certified OBD equipment specifically approved for the HD I/M program. This distinction matters because there are general smog shops in the La Verne and Pomona Valley area that may not have this specific credential and a test performed with non-approved equipment produces a result CARB will not accept.
We serve Los Angeles County, which includes La Verne and the surrounding Pomona Valley area. The Clean Truck Check OBD test requires a CARB-credentialed tester with CARB-certified equipment but it doesn’t require a fixed testing bay the way some other inspections do. The test connects directly to your truck’s OBD port, which means it can be performed wherever your truck is located, as long as the tester and equipment are approved by CARB.
For operators staging trucks at locations like San Polo Business Park, the La Verne Business Park near Brackett Field, or a yard in the area, this is a practical consideration. Driving a loaded semi across the Pomona Valley to a testing facility and losing hours of revenue in the process isn’t always realistic. Contact us directly to discuss scheduling and location options for your specific situation. The goal is to get your truck tested and your results submitted to CTC-VIS with as little disruption to your operation as possible.
Yes, they’re two separate charges. California’s Clean Truck Check program requires qualifying truck owners to pay an annual compliance fee through CARB’s CTC-VIS system in 2025, that fee is $31.18 per vehicle, and it’s adjusted annually based on the Consumer Price Index. This fee is paid directly to CARB through the CTC-VIS portal and is separate from whatever a credentialed tester charges to perform the actual OBD emissions test.
The testing fee what you pay us to perform the Clean Truck Check covers the OBD scan using CARB-certified equipment and the direct electronic submission of your results to CTC-VIS. These are two distinct costs, and understanding that upfront avoids confusion when you’re budgeting for compliance. For operators managing multiple trucks out of the La Verne area, both costs scale per vehicle so knowing the full picture per unit helps you plan the compliance schedule accurately, especially as testing frequency increases to quarterly by October 2027.
