California doesn’t mess around with heavy-duty vehicle compliance. If your 2013 or newer truck with a GVWR over 14,000 pounds isn’t tested and reported through the CTC-VIS system, you’re looking at registration holds, fines up to $10,000 per vehicle per day, and trucks sitting idle instead of earning.
Clean Truck Check testing isn’t optional anymore. Deadlines started January 1, 2025, and CARB is actively screening high-emitter vehicles on the road. Miss your testing window and you’ll deal with notices, penalties, and the kind of downtime that costs $300 to $900 per vehicle—every single day.
We handle the OBD scan, submit your results to CARB, and get you the compliance certificate you need. The test takes less than five minutes. You get back to work without the stress of navigating CARB’s regulations on your own or wondering if you did it right.
All SMOG Motors has been handling emissions testing in Rancho Palos Verdes for years. We’re CARB credentialed testers, which means we’ve passed the state exam and use certified OBD testing equipment that meets California Air Resources Board standards.
Rancho Palos Verdes sits right in the heart of South Bay’s commercial corridor. Trucks moving through the Port of Los Angeles, servicing businesses across the Peninsula, or operating throughout LA County all need to meet the same strict CARB diesel compliance requirements. We’re here because this community has working trucks that can’t afford to sit.
You’re not getting a generic smog shop trying to figure out heavy-duty regulations. You’re getting a team that knows exactly what CARB requires for 2013 and newer trucks, how the CTC-VIS system works, and how to keep your fleet compliant without the runaround.
You bring your 2013 or newer heavy-duty truck to our Rancho Palos Verdes location. We plug into your truck’s OBD system using CARB-certified testing equipment and run the diagnostic scan. The whole process takes under five minutes.
Once the scan is complete, we submit your test results directly to CARB through the CTC-VIS system. If your truck passes, you receive a certificate of compliance on the spot. That certificate proves your vehicle meets California CARB compliant standards and is legal to operate on state roads.
You’ve got a 90-day window to submit test results before your applicable deadline. We make sure everything is filed correctly so there’s no confusion with the DMV, no registration holds, and no surprise penalties. Your truck stays on the road, and you stay focused on your business instead of paperwork.

This isn’t a standard smog test. Clean Truck Check applies specifically to trucks with 2013 and newer diesel engines and a GVWR over 14,000 pounds. If your truck is older or lighter, this service doesn’t apply to you—and we won’t pretend it does.
You’re getting a CARB HD I/M test performed by a credentialed tester using state-approved equipment. We scan your engine’s OBD data, check for emissions system faults, and verify your truck meets California’s heavy-duty inspection and maintenance standards. Then we handle the CTC-VIS reporting so CARB and the DMV have your compliance on file.
Rancho Palos Verdes is a hub for commercial operations serving the greater Los Angeles area. Trucks running through here are under constant scrutiny from CARB’s roadside monitoring. One high-emitter flag and you’ve got 30 days to submit to testing or face enforcement. We’re set up to handle that urgency without making you wait weeks for an appointment.
Right now, testing is required every six months. Starting in October 2027, OBD-equipped vehicles will need testing four times per year. The requirements are only getting stricter, and the penalties for non-compliance aren’t going away. Getting this done right, on time, and with a credentialed tester is the only way to avoid the headaches.
If your truck has a 2013 or newer diesel engine and a gross vehicle weight rating over 14,000 pounds, yes—you need this test. It doesn’t matter if you own the truck, lease it, or operate it under a fleet. It doesn’t matter if it’s registered in California or out of state. If it operates on California roads, CARB requires compliance.
This includes semi trucks, heavy-duty buses, commercial vehicles, and any diesel-powered truck that meets the weight and year requirements. Lighter trucks, older models, and gasoline-powered vehicles are not subject to Clean Truck Check regulations.
CARB is actively screening vehicles on the road using emissions monitoring equipment. If your truck gets flagged as a high emitter, you’ll receive a Notice to Submit to Testing and have 30 days to comply. Don’t wait for that notice—get tested during your compliance window and avoid the enforcement process entirely.
Right now, you need to test every six months. CARB sets specific deadlines based on your vehicle, and you’ve got a 90-day window before each deadline to submit your test results through the CTC-VIS system.
Starting in October 2027, the frequency increases to four times per year for OBD-equipped vehicles. That’s a significant jump, and it means staying on top of your compliance schedule becomes even more critical.
Missing a deadline doesn’t just mean a slap on the wrist. The DMV checks compliance status when your truck is due for registration. If you’re not current, they’ll place a registration hold. Your truck can’t legally operate until you get tested, submit results, and clear the hold. That’s lost revenue, frustrated customers, and penalties piling up while your truck sits.
If your truck fails, it means the OBD scan detected emissions system faults or issues that put you out of compliance with CARB regulations. You’ll need to get those issues repaired before you can pass and receive your compliance certificate.
We’ll tell you exactly what the scan found so you know what needs fixing. Once repairs are done, you come back for a retest. The goal is to get you compliant as quickly as possible so your truck can get back on the road legally.
Failing isn’t the end of the world, but ignoring it is. Operating a non-compliant truck in California exposes you to fines up to $10,000 per vehicle per day, registration holds, and potential enforcement action from CARB. Get it fixed, get retested, and get your certificate. That’s the only path forward.
Pricing varies depending on whether you’re bringing in a single truck or managing a fleet. Testing itself is quick—under five minutes—but you’re also paying for CARB-certified equipment, a credentialed tester, and proper CTC-VIS reporting.
On top of the test, CARB charges an annual compliance fee of $31.18 per vehicle. That’s separate from what you pay for the actual testing service, and it’s non-negotiable. It’s part of the state’s program to fund enforcement and monitoring.
What you’re really paying for is avoiding penalties. Fines start at $1,000 per day and can climb to $75,000 depending on the violation. Downtime costs you $300 to $900 per vehicle per day. Compare that to the cost of a quick test and compliance certificate, and the math is pretty straightforward.
You can’t just go anywhere. CARB requires that Clean Truck Check testing be performed by a credentialed tester who has passed the state exam and uses certified OBD testing equipment. Not every smog shop is set up for this—most handle light-duty passenger vehicles, not heavy-duty trucks.
We’re CARB credentialed specifically for this testing. We’ve got the equipment, the certification, and the experience with California’s heavy-duty emissions regulations. You’re not walking into a place that’s guessing or learning on the fly.
Rancho Palos Verdes and the surrounding South Bay area have plenty of trucks that need this service, but not a lot of locations equipped to handle it correctly. Going to a credentialed tester means your results get submitted properly, your compliance is on record, and you don’t have to worry about errors that could cost you down the line.
Bring your truck, your vehicle registration, and any documentation related to your CTC-VIS account if you’ve already registered with CARB. If this is your first time getting tested, we can help you understand what CARB needs on file.
The truck needs to be operational and ready for the OBD scan. If your check engine light is on or you’re already aware of emissions system issues, get those addressed before coming in. A truck with active faults won’t pass, and you’ll just end up needing a retest after repairs.
Make sure your truck is actually subject to Clean Truck Check requirements—2013 or newer diesel engine, GVWR over 14,000 pounds. If you’re not sure, call ahead. We’d rather confirm eligibility before you make the trip than waste your time with a service that doesn’t apply to your vehicle.
