If you’re running a 2013 or newer diesel truck over 14,000 pounds in Santa Fe Springs, you already know the DMV isn’t playing around with Clean Truck Check requirements anymore. Registration holds started going out in August 2024, and if you haven’t passed your CARB emissions testing, you’re stuck.
This isn’t a regular smog check. It’s a heavy-duty vehicle compliance requirement that scans your truck’s OBD system and reports directly to CARB. Miss it, and you’re looking at registration holds, penalties up to $10,000 per vehicle per day, and worst of all—downtime you can’t afford.
You need testing done by someone who’s actually CARB credentialed, using certified equipment, and who knows how to get your results submitted to the CTC-VIS system so your DMV hold gets lifted in 1-3 business days. That’s what keeps your trucks moving and your business running in one of the busiest trucking corridors in California.
We serve the Santa Fe Springs trucking community with CARB credentialed testers who understand heavy-duty vehicle compliance. We’re not a general smog shop trying to figure out diesel trucks on the fly—we focus specifically on the Clean Truck Check program for 2013 and newer trucks over 14,000 lbs GVWR.
Santa Fe Springs has over 845 carriers shipping through the area. That’s a lot of trucks that need twice-yearly testing starting in 2025, ramping up to four times per year by 2027. You need someone local who gets the urgency, knows the regulations, and won’t waste your time with incorrect tests or delayed reporting.
We use CARB certified OBD testing devices and submit results instantly through the CTC-VIS system. That means your vehicle record updates with CARB and the DMV without you having to chase down paperwork or wonder if it went through.
You schedule your Clean Truck Check appointment, and we come to you—or you come to us in Santa Fe Springs. Either way, the test itself takes less than 20 minutes for trucks that pass.
We connect our CARB certified OBD scanner to your truck’s diagnostic port and pull the emissions data directly from your engine’s computer system. This isn’t a tailpipe test. It’s a scan of your emission control systems to make sure everything’s functioning the way CARB requires for 2013 and newer diesel engines or 2018 and newer alternative fuel engines over 14,000 pounds.
Once the scan is complete and your truck passes, we submit the results immediately to the CTC-VIS database. CARB and the DMV get notified, and if you had a registration hold, it typically clears within 1-3 business days. If your truck doesn’t pass, we’ll tell you exactly what flagged and what needs attention before you can retest.
You walk away knowing your CARB diesel compliance is handled, your registration is clear, and you’re legal to operate on California roads and access ports or freight terminals that require proof of compliance.

As of January 1, 2025, all California-registered trucks over 14,000 lbs GVWR with 2013 or newer diesel engines need to pass a Clean Truck Check twice per year. That frequency increases to four times per year by 2027. If your truck gets flagged as a high emitter during roadside screening—which CARB started doing in January 2023—you have 30 calendar days to submit a passing test or face enforcement action.
This applies to semi trucks, commercial fleets, construction vehicles, waste haulers, and even motorhomes registered in California that meet the weight and model year requirements. Santa Fe Springs sits in the heart of LA County’s logistics network, so enforcement is active and visible here.
The DMV won’t renew your registration if you’re out of compliance. CARB can issue penalties. And if you’re trying to enter a port, terminal, or job site that checks compliance status, you’re getting turned away. The cost of non-compliance isn’t just a fine—it’s lost work, missed loads, and trucks sitting idle when they should be earning.
We handle the full CARB emissions testing process for trucks that qualify under the Clean Truck Check program. We’re credentialed, we’re local to Santa Fe Springs, and we know how tight your schedule is. You’re not getting the runaround or delayed results. You’re getting tested, reported, and cleared so you can move on.
No. The Clean Truck Check program only applies to trucks with 2013 or newer diesel engines, or 2018 or newer alternative fuel engines, that weigh over 14,000 lbs GVWR. If your truck is a 2012 or older diesel, it’s not subject to this specific CARB HD I/M testing requirement.
That said, older trucks may still have other California smog check or CARB compliance obligations depending on how they’re registered and used. But the twice-per-year OBD scan through the CTC-VIS system? That’s only for the newer, OBD-equipped heavy-duty vehicles that fall into the 2013+ diesel or 2018+ alternative fuel categories.
If you’re not sure whether your truck qualifies, bring us your VIN and registration. We’ll tell you exactly what applies and what doesn’t, so you’re not paying for testing you don’t actually need.
Once you pass your Clean Truck Check and we submit the results to CARB’s CTC-VIS system, the DMV typically lifts the registration hold within 1-3 business days. The system updates automatically, so you’re not stuck waiting on manual processing or mailed paperwork.
That’s assuming you pass the test and there are no other holds or issues on your registration. If your truck fails, you’ll need to address whatever emission control issue flagged, get it fixed, and then retest before the hold can be removed.
The key is getting tested by a CARB credentialed tester who submits results correctly the first time. Incorrect submissions or testing done by non-credentialed providers won’t update your record, which means your hold stays in place and you’re still out of compliance. We handle the reporting directly, so there’s no gap between your passing test and your DMV record getting cleared.
If your truck fails, the test results will show which emission control system or component triggered the failure. Common issues include malfunctioning diesel particulate filters, faulty NOx sensors, or problems with the selective catalytic reduction system. The OBD scan pulls diagnostic trouble codes directly from your engine’s computer, so the failure isn’t a guess—it’s specific.
You’ll need to get the flagged issue repaired by a qualified diesel mechanic, then bring your truck back for a retest. CARB requires the problem to be fixed and the system to show compliant readings before you can pass. There’s no workaround or grace period if you’re flagged as a high emitter or if you’re trying to clear a registration hold.
If your truck fails and you’re under a 30-day deadline because you were flagged during roadside screening, that clock doesn’t stop. You need to move fast to get repairs done and get retested before CARB escalates to penalties or enforcement action. We’ll walk you through what failed and what your next steps are, but the repair work itself has to happen before we can pass you.
No. Clean Truck Check testing has to be performed by a CARB credentialed tester using CARB certified OBD testing equipment that connects to the CTC-VIS system. Not every smog shop has that credential, that equipment, or access to the reporting database. If you go somewhere that isn’t set up for heavy-duty vehicle compliance testing, they can’t legally perform your Clean Truck Check—and even if they try, the results won’t get submitted to CARB or the DMV.
This isn’t the same as a regular passenger vehicle smog test. The equipment is different, the reporting system is different, and the training requirements are different. CARB credentialed testers have to renew their certification every two years and stay current on the program’s requirements.
We’re credentialed and equipped specifically for this program. We’re local to Santa Fe Springs, we test trucks over 14,000 lbs that are 2013 or newer, and we submit results directly to CTC-VIS so your compliance record updates correctly. Don’t assume every shop can do this—most can’t.
Starting January 1, 2025, you’re required to test twice per year if your truck is 2013 or newer, weighs over 14,000 lbs GVWR, and operates on California public roads. That frequency increases to four times per year starting in 2027. These aren’t optional—they’re mandatory compliance deadlines tied to your registration and your legal ability to operate.
If your truck gets flagged as a high emitter during CARB’s roadside emissions monitoring, you’ll also receive a Notice to Submit to Testing. That gives you 30 calendar days to complete a passing Clean Truck Check, regardless of when your last test was. Miss that deadline, and you’re facing penalties and potential registration holds.
The testing schedule is aggressive, especially for fleets running multiple trucks in Santa Fe Springs. You’re looking at coordinating tests for every qualifying vehicle twice a year minimum, and that’s on top of all your other maintenance and compliance obligations. The earlier you build this into your schedule, the less scrambling you’ll do when deadlines hit.
CARB can issue penalties up to $10,000 per vehicle per day for non-compliance. The DMV will place a registration hold on your truck, which means you can’t renew your registration until you pass a Clean Truck Check and submit proof to CARB. And if you’re caught operating a non-compliant truck on California roads, you’re subject to additional enforcement action.
Beyond the fines, the real cost is operational. If your registration is on hold, your truck is grounded. If you show up to a port, freight terminal, or job site that checks CARB compliance, you’re getting turned away. That’s lost revenue, missed contracts, and a reputation hit you don’t need in a competitive market like Santa Fe Springs.
The program went into full enforcement mode in 2024, and CARB isn’t issuing warnings anymore—they’re issuing holds and penalties. The cost of staying compliant is a 20-minute test twice a year. The cost of ignoring it is exponentially higher, and it’s not a risk worth taking when your livelihood depends on keeping your trucks on the road.
