Your trucks stay on the road. Your DMV registration doesn’t get blocked. You’re not scrambling to explain a $10,000-per-day penalty to your accountant or your boss.
CARB compliance isn’t optional anymore. Starting January 2025, every commercial vehicle over 14,000 pounds operating in California needs semi-annual emissions testing. Miss it, and you’re looking at fines that start at $1,000 and climb fast. Worse, your registration gets flagged, which means your trucks sit idle while you sort it out.
You need testing done right, submitted directly to CARB, and documented properly. That’s what keeps your fleet moving and your business operating without interruption. No surprises. No last-minute panic. Just proof that your trucks meet California’s diesel compliance standards when it matters.
All SMOG Motors has been handling diesel emissions testing in Santa Monica since the regulations were simpler and the stakes were lower. They’re not anymore.
We’re CARB certified testers with direct access to CARB systems for immediate submission and issue resolution. That certification matters because only state-approved testers can generate valid test results that CARB actually accepts. We’ve helped Santa Monica fleet operators, independent owner-operators, and out-of-state truckers navigate these requirements without the confusion or wasted time.
Santa Monica’s proximity to the ports and major freight corridors means heavy-duty vehicle compliance is part of doing business here. We know the local trucking landscape, the common compliance issues, and how to get your trucks tested efficiently so you’re back to work.
First, we verify your truck qualifies. This service is specifically for trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. If your truck meets those criteria, you’re in the right place. Older trucks or lighter vehicles require different testing that we don’t cover.
Next, we run the OBD emissions test using CARB certified testing equipment. For 2013 and newer diesel engines, this means plugging into your truck’s onboard diagnostics system to check emission control systems. It’s faster and more straightforward than the smoke opacity testing required for older trucks. The test itself takes minutes, not hours.
Once testing is complete, we submit results directly to CARB through the CTC-VIS portal. You get your Clean Truck Check certificate, and CARB gets the documentation they need to keep your registration clear. We also help with CTC-VIS registration if you’re not already set up, because that’s required before testing can even happen.
If your truck doesn’t pass, we’ll tell you why and what needs fixing. Then we offer 50% off the retest once repairs are done. The goal is getting you compliant, not dragging out the process.

You get certified OBD testing performed by a CARB credentialed tester. That credential is non-negotiable. Without it, your test results won’t be accepted by CARB, which means you’re still non-compliant even after paying for a test somewhere else.
We handle direct submission to CARB so your results are on file immediately. No waiting. No wondering if it went through. We also provide FREE assistance with CTC-VIS portal registration and setup, which is required before your first test. Most operators find that portal confusing, so we walk you through it.
For Santa Monica fleets, we offer mobile testing services. We come to your yard or facility anywhere in the area, test your trucks on-site, and submit everything while you keep working. That eliminates the 1-3 hours of downtime per truck you’d lose driving to a testing facility and waiting in line.
We also keep records for your fleet and provide updates on upcoming deadlines. Starting in 2027, testing frequency increases to four times per year for OBD-equipped vehicles. That’s a lot of deadlines to track, especially if you’re running multiple trucks. We make sure you know when testing is due so you’re never caught off guard.
Yes. CARB compliance applies to any commercial vehicle over 14,000 pounds operating in California, regardless of where it’s registered.
If your truck crosses into California for work, it needs to meet California’s emissions standards. That means semi-annual testing, a valid Clean Truck Check certificate, and registration in the CTC-VIS system. Out-of-state operators sometimes assume they’re exempt, but CARB uses roadside monitoring devices and automated license plate readers to identify non-compliant vehicles. When they catch you, the penalties apply the same as they would to a California-registered truck.
The testing requirement exists to reduce diesel emissions across all heavy-duty vehicles operating in the state. It doesn’t matter if you’re based in Nevada, Arizona, or anywhere else. If you’re doing business in California, your truck needs to be compliant before it crosses the state line.
You’ll get a detailed report explaining what failed and why. Then you need to make the necessary repairs before retesting.
Common failures include malfunctioning emission control systems, faulty sensors, or issues with the diesel particulate filter. The OBD system will flag specific error codes, so you’re not guessing what’s wrong. Take that report to a qualified diesel mechanic who can address the issues. Once repairs are complete, bring the truck back for a retest.
We offer 50% off retests after repairs, which helps offset the cost of getting your truck compliant. The key is addressing the problem quickly. Every day your truck sits non-compliant is another day it can’t legally operate in California, and another day you’re at risk for penalties if CARB catches you on the road. Get it fixed, get it retested, and get back to work.
Right now, it’s twice a year. Starting October 2027, it increases to four times a year for trucks with OBD systems.
The current requirement is semi-annual testing for all commercial vehicles over 14,000 pounds. That means every six months, you need a passing emissions test submitted to CARB. You also need to pay the annual $30 compliance fee and meet the submission deadlines, or your DMV registration gets flagged.
In 2027, the frequency doubles for OBD-equipped vehicles like your 2013 or newer truck. That’s every three months. It sounds like a lot, but the testing itself is quick when you’re working with a certified tester who can come to you. The bigger issue is tracking deadlines and making sure you don’t miss one, because that’s when penalties kick in. We help fleet operators stay on top of those schedules so nothing slips through.
No. This service is only for trucks that are model year 2013 or newer with a GVWR over 14,000 pounds.
Trucks older than 2013 require smoke opacity testing, which is a different process with different equipment. We specialize in OBD emissions testing for newer heavy-duty trucks because that’s where the regulations are tightest and the testing requirements are most specific. If your truck is older than 2013, you’ll need to find a facility that offers smoke opacity testing.
This isn’t about turning away business. It’s about doing one thing really well and making sure customers get the right service for their specific vehicle. If your truck is 2013 or newer and over 14,000 pounds, we’re the right fit. If it’s not, we’d rather point you in the right direction than waste your time with a service that doesn’t apply to your situation.
CTC-VIS is CARB’s online system for tracking Clean Truck Check compliance. You need to register your vehicles in it before you can get tested.
The portal is where CARB monitors which trucks have been tested, when they’re due for retesting, and whether they’ve paid the annual compliance fee. Without registration, there’s nowhere for your test results to go, which means you can’t get a valid Clean Truck Check certificate. It’s a required first step, and it trips up a lot of operators because the portal isn’t exactly intuitive.
We provide free assistance with CTC-VIS registration and setup. We’ll walk you through creating your account, adding your vehicles, and making sure everything is entered correctly so your first test goes smoothly. Once you’re registered, future tests are straightforward because your vehicle information is already in the system. It’s one of those administrative hurdles that’s easier with someone who’s done it a hundred times.
Testing costs vary, but in-person testing at CARB facilities can run up to $300 per truck. The test itself takes minutes, but the total time depends on whether you’re driving to a facility or using mobile service.
If you drive to a testing location, factor in travel time, wait time, and the time your truck is off the road. That can easily add up to 1-3 hours of downtime per vehicle, which translates to $300-$900 in lost productivity depending on your operation. For a fleet, that downtime multiplies fast.
Mobile testing eliminates most of that. We come to your location in Santa Monica, test your trucks on-site, and submit results while your operation keeps running. The actual OBD test is quick because we’re plugging into your truck’s diagnostic system, not running a full smoke opacity test like older trucks require. You’re looking at minutes per truck, not hours. The bigger time-saver is not having to pull trucks off jobs or routes just to drive them to a testing facility across town.
