California doesn’t mess around with heavy-duty vehicle compliance. If your truck fails CARB emissions testing or you skip it altogether, you’re facing penalties up to $10,000 per vehicle per day. That’s not a scare tactic—that’s what CARB collected $21.5 million enforcing in 2022 alone.
Your DMV registration gets blocked. Your truck can’t legally operate on California roads. And while it sits, you’re losing contracts, disappointing customers, and watching revenue disappear.
CARB compliance isn’t optional anymore. Every semi truck and heavy-duty diesel with a 2013 or newer engine and a GVWR over 14,000 pounds needs testing twice a year. Starting in 2027, that jumps to four times annually. You need a CARB credentialed tester who knows the OBD requirements, reports results into the CTC-VIS system, and gets you a passing TRUCRS certificate so you can get back to work.
All SMOG Motors is a CARB credentialed testing facility serving French Valley and the surrounding Riverside County area. We’re licensed to perform emissions testing on 2013 and newer heavy-duty trucks, and we understand exactly what California requires to keep your fleet compliant.
French Valley has a strong commercial presence—over 17,500 working residents with nearly 8% running their own businesses. That means a lot of trucks moving through this area, and a lot of operators who need reliable CARB diesel compliance testing without the runaround.
We’re not here to upsell you or waste your time. You need a smog test that passes, gets reported correctly, and keeps your registration current. That’s what we do.
First, we verify your truck qualifies—model year 2013 or newer with a GVWR over 14,000 pounds. If it doesn’t meet both criteria, this testing doesn’t apply to you.
Next, we connect to your truck’s OBD system using CARB certified testing equipment. We’re scanning for emissions data, fault codes, and system readiness. This isn’t a visual inspection—it’s a diagnostic scan that measures whether your truck meets California CARB compliant standards.
If your truck passes, we submit the results directly into the CTC-VIS system and provide you with a TRUCRS certificate. That certificate proves compliance and clears any registration holds with the DMV. If something fails, we’ll tell you exactly what needs fixing before you can retest. You’ve got 30 days from notification to submit a passing test, so time matters.
The whole process typically takes under an hour if your truck is ready and your systems are functioning properly. No appointment drama, no surprise fees—just straightforward testing so you can stay legal.

You’re paying for certified CARB compliance testing performed by a credentialed tester, which is the only type of testing California accepts. You’re also paying the state’s annual compliance fee—currently $32.13 per vehicle as of 2026—which we collect and submit on your behalf.
Here’s what matters for French Valley operators: if your truck is registered in California, your testing schedule is tied to your DMV registration expiration. You need a passing smog check twice a year, and those tests need to happen within specific windows. Miss the deadline, and your registration renewal gets blocked.
Out-of-state trucks aren’t off the hook either. If you’re operating in California, you’re subject to the same Clean Truck Check requirements. CARB has been using roadside emissions monitoring since January 2023, and they’re actively screening for high emitters. Get flagged, and you’ve got 30 days to test and pass—or face enforcement violations.
This isn’t about being difficult. California is targeting 7,500 fewer air-quality deaths and $75 billion in health benefits from this program. The regulations aren’t going away. They’re getting stricter. Your best move is staying ahead of the deadlines and keeping your trucks compliant before you get pulled over or flagged by a monitoring device.
No. This specific testing only applies to heavy-duty trucks with 2013 or newer engines and a GVWR over 14,000 pounds.
If your truck is older or lighter, you’re not subject to the Clean Truck Check program. California has other emissions requirements for different vehicle classes, but the OBD-based CARB emissions testing we’re talking about here is limited to that 2013+ threshold.
Don’t let anyone tell you otherwise or try to test a truck that doesn’t qualify. It’s a waste of your time and money, and it won’t satisfy any actual compliance requirement you might have under a different program.
Right now, you need CARB compliance testing twice a year—every six months. That started in 2025 for all applicable heavy-duty vehicles, whether you’re based in California or just operating here.
Starting in October 2027, the frequency increases to four times per year for OBD-equipped trucks. That’s every three months, which means tighter scheduling and more planning if you’re managing a fleet.
Your testing windows are based on your DMV registration expiration date if you’re a California-registered vehicle. For out-of-state operators, you’ll need to track your own compliance deadlines and make sure you’re testing on schedule before entering California. Missing a test means you’re operating illegally, and that opens you up to fines and registration holds.
If your truck fails, you’ll get a detailed report showing exactly what triggered the failure—usually fault codes, emissions readings, or system readiness issues. You can’t get a TRUCRS certificate until those issues are fixed and you pass a retest.
You typically have 30 days from the failure notice to get repairs done and submit a passing test. If you’re already under a compliance deadline or facing a registration renewal, that timeline gets tight fast.
Some failures are simple—a sensor that needs replacing or a software update. Others point to bigger problems with your emissions system, which means more expensive repairs. Either way, you need to address it with a qualified mechanic, then come back for another test. We don’t do the repairs ourselves, but we’ll tell you exactly what needs fixing so you’re not guessing.
It has to be done by a CARB credentialed tester at a licensed facility. California doesn’t accept results from non-credentialed testers, and the test results have to be submitted directly into the state’s CTC-VIS system to count.
That means you can’t just go to any smog shop. You need a facility that’s specifically certified for heavy-duty vehicle compliance and equipped with CARB certified OBD testing devices. Not all smog check stations have that credential or equipment.
All SMOG Motors is a CARB credentialed testing facility in French Valley, which means we’re authorized to perform the test, submit the results, and issue your TRUCRS certificate. If you go somewhere that isn’t credentialed, you’ll waste time and money on a test that doesn’t satisfy California’s requirements.
The state compliance fee is $32.13 per vehicle as of 2026, and that’s non-negotiable—it goes directly to CARB. Testing fees vary by facility, but in-person testing at some CARB facilities can run up to $300 per test.
We keep our pricing straightforward and competitive for French Valley truck operators. You’re paying for the test itself, the compliance fee, and the time it takes to run the diagnostics and submit your results. No hidden charges, no surprise add-ons.
What costs more than the test is failing to get it done. A single day of non-compliance can trigger fines up to $10,000 per vehicle. A blocked registration means your truck sits idle, and every day it’s not working costs you revenue. Spending a couple hundred dollars twice a year to stay compliant is a lot cheaper than dealing with penalties, downtime, and lost contracts.
Yes. If your heavy-duty truck operates in California—even temporarily—you’re subject to the same Clean Truck Check requirements as California-registered vehicles. That means 2013 or newer trucks over 14,000 pounds GVWR need CARB emissions testing twice a year.
CARB has been using roadside emissions monitoring devices since January 2023 to screen trucks for high emissions. If your truck gets flagged, you’ll receive a notice requiring you to submit a passing test within 30 days, regardless of where you’re registered.
Out-of-state operators often don’t realize they’re subject to California’s rules until they get pulled over or flagged. By then, you’re on a tight deadline and scrambling to find a credentialed testing facility. If you’re running routes through California regularly, it’s smarter to get tested on schedule and keep your TRUCRS certificate current so you’re not dealing with enforcement violations on the road.
