La Puente sits right on the edge of one of the busiest freight corridors in the country. If you’re hauling out of the City of Industry, running loads down the SR-60, or making port runs to Los Angeles or Long Beach, your compliance certificate isn’t just paperwork it’s what gets you through the gate and keeps the work coming. Let it lapse, and freight brokers and port facilities will turn you away before you even unload.
The SR-60 and I-10 corridors that La Puente operators use every day are exactly where CARB deploys roadside monitoring equipment. That means your truck can be flagged as a potential high emitter without ever being pulled over. If that happens, you’ve got 30 days to submit a passing test from a credentialed tester or face fines that can reach $10,000 per vehicle per day.
When you test with us, your results go directly into CARB’s CTC-VIS database at the time of testing. No portal. No manual upload. No wondering if it went through. Your truck is compliant, documented, and ready to work same day.
We are a CARB-credentialed Clean Truck Check testing provider serving Los Angeles County including La Puente and the surrounding San Gabriel Valley communities of Valinda, West Puente Valley, and South San Jose Hills. Every tester on our team holds a current state-issued HD I/M credential that appears on CARB’s public database. You don’t have to take our word for it. You can look it up yourself before you ever book.
We test exclusively on model year 2013 or newer heavy-duty diesel vehicles with a GVWR over 14,000 pounds the exact trucks subject to California’s Clean Truck Check program. This isn’t a side service we added to fill gaps. It’s the only thing we do, and we do it with CARB-certified OBD equipment designed specifically for this program. Results from non-approved devices get rejected. Ours don’t.
For owner-operators running trucks out of La Puente and into the City of Industry every day, that distinction matters more than most people realize until it’s too late.
You schedule your test, we show up with CARB-certified OBD equipment, and we connect directly to your truck’s onboard diagnostic system. The scan reads your emissions data in real time. If your truck passes, we submit the results electronically to CARB’s CTC-VIS database on the spot your compliance record is updated immediately, no portal login required on your end.
If your truck doesn’t pass, you’ll know exactly what’s flagged and why. A failed test isn’t an automatic fine it’s a signal to get the issue repaired before your deadline hits. We’ll walk you through what CARB needs to see on a retest so you’re not guessing. For La Puente operators who received a Notice to Submit to Testing after being flagged on the SR-60 or I-10, that 30-day clock moves fast. Knowing where you stand on day one gives you the maximum time to handle any repairs without the pressure of a missed deadline hanging over you.
The whole process is straightforward. No unnecessary steps, no paperwork you have to chase down, and no confusion about whether your test actually counted with CARB.

We perform CARB Clean Truck Check OBD testing on model year 2013 or newer diesel trucks with a GVWR over 14,000 pounds. If your truck is older than 2013 or under that weight threshold, this program does not apply to your vehicle and we won’t waste your time telling you otherwise.
For trucks that do qualify, here’s what the service covers: a full OBD emissions scan using CARB-certified testing equipment, real-time data review, and direct electronic submission of your results to the CTC-VIS database. You walk away with a current compliance record on file with CARB no follow-up required on your end.
California currently requires semi-annual testing, meaning your truck needs to be tested twice per year. By October 2027, that requirement escalates to quarterly four times per year. For La Puente owner-operators running one or two trucks out of this area and into the City of Industry or down to the ports, that cadence is only going to increase. The $31.18 annual CARB compliance fee is paid separately through the CTC-VIS system that’s a state fee, not our testing fee. Both together are a fraction of what a single day of non-compliance can cost you.
If your truck is a model year 2013 or newer heavy-duty diesel vehicle with a GVWR over 14,000 pounds and it operates in California, yes it is subject to CARB’s Clean Truck Check program regardless of where you’re based. La Puente is in Los Angeles County, which falls squarely within CARB’s enforcement territory. The SR-60 and I-10 corridors that most La Puente-area operators use daily are among the most actively monitored freight routes in the state.
Being based in La Puente doesn’t exempt you from the requirement. The program applies to the vehicle and where it operates, not the type of city you live in. If your truck runs loads out of the City of Industry, makes port runs to Los Angeles or Long Beach, or travels any California highway, you need a current compliance certificate on file with CARB.
CARB uses Remote Emissions Monitoring Devices roadside equipment that can scan passing trucks for high emissions without a traffic stop. The SR-60 and I-10 through the La Puente and City of Industry corridor are exactly the type of high-volume freight routes where this equipment is deployed. If your truck gets flagged, CARB will mail you a Notice to Submit to Testing, and from the date you receive it, you have 30 calendar days to submit a passing emissions compliance test performed by a credentialed tester.
That 30-day window sounds like enough time, but it moves fast especially if your truck needs repairs before it can pass. The smartest move is to get tested as early in that window as possible. If there’s a problem, you want to know on day three, not day twenty-eight. We perform the OBD scan with CARB-certified equipment and submit your results directly to CTC-VIS, so your response to the NST is documented immediately.
These are two separate charges, and they’re commonly confused. The $31.18 annual CARB compliance fee is paid directly to the state through the CTC-VIS portal it’s a per-vehicle registration fee that keeps your truck enrolled in the Clean Truck Check program. You pay that to CARB, not to us.
The testing fee is what you pay us to perform the actual OBD emissions scan using CARB-certified equipment and submit your results to CARB’s database. That’s the service we provide. Both fees are required for full compliance, but they’re handled separately. A lot of La Puente owner-operators come in thinking they’ve already paid for the test because they paid the annual fee that’s not the case. The annual fee keeps your account active. The test is what generates the compliance record CARB actually needs to see.
As of 2025, California’s Clean Truck Check program requires semi-annual testing meaning your qualifying truck needs to pass a CARB emissions compliance test twice per year. That schedule is already in effect, and it’s not optional.
What a lot of operators in the La Puente area don’t realize yet is that the testing frequency is increasing. By October 2027, the requirement escalates to quarterly testing four times per year. For someone running one or two trucks out of La Puente into the City of Industry or down to the ports, that means compliance testing becomes a regular, recurring part of your operating schedule, not a once-a-year task you can set and forget. Building a relationship with a credentialed tester now rather than scrambling to find one every time a deadline hits is the practical move.
A failed test is not an immediate fine. It’s information. When your truck fails, CARB’s system records the result, and you now know there’s an emissions issue that needs to be addressed before you can get a passing compliance certificate. The key is what you do next and how quickly you do it.
If you’re testing in response to a Notice to Submit to Testing which is common for La Puente operators whose trucks travel the SR-60 and I-10 regularly your 30-day deadline is still running. A failed test doesn’t reset the clock. You’ll need to make the necessary repairs and come back for a retest before that window closes. We’ll tell you exactly what the OBD scan flagged so you can take that information directly to a diesel mechanic. We’re not a repair shop, but we can tell you clearly what CARB’s system identified so you’re not walking into a shop without a starting point.
Yes. Whether you’re running one truck or managing several vehicles registered to La Puente-area addresses, the process is the same and our direct-submission model actually makes fleet compliance significantly easier to manage. Every truck we test gets its results submitted directly to CTC-VIS at the time of testing. That means each vehicle’s compliance record is updated individually and immediately, without you or anyone on your team having to log into a portal and manage submissions manually.
For small fleet operators in La Puente who are running trucks in and out of the City of Industry, keeping track of multiple compliance deadlines across multiple vehicles is a real administrative burden. When your tester handles the submission side entirely, that burden goes away. You know the test happened, you know the result was submitted, and you can confirm the record in CTC-VIS yourself if you want to verify it. No chasing paperwork, no uncertainty about whether a submission went through.
