You’re running a business, and every day a truck sits idle costs you money. CARB compliance isn’t optional anymore—it’s the law. And the penalties for getting it wrong aren’t just annoying. They’re brutal.
We’re talking fines up to $10,000 per vehicle per day. Registration holds that keep your trucks off the road. Roadside enforcement that pulls your drivers over and puts you on CARB’s radar. If your trucks are 2013 or newer with a GVWR over 14,000 pounds, you need semi-annual OBD emissions testing. No exceptions.
Here’s what proper CARB compliance actually gets you: your trucks stay registered, your drivers stay on schedule, and you avoid the kind of penalties that can cripple a fleet operation. You’re not dealing with surprise inspections or scrambling to fix issues after the fact. You’re ahead of it.
Starting in 2027, testing goes from twice a year to four times a year for these vehicles. The requirements aren’t getting easier. You need a testing partner who knows the regulations, has the right equipment, and doesn’t waste your time.
We specialize in one thing: CARB emissions testing for heavy-duty diesel trucks. Not passenger cars. Not light-duty vehicles. Just the big rigs that require OBD testing and CARB credentialed testers who know what they’re doing.
We’re located in Rosemead, CA, right off I-605 and SR-22. That’s not an accident. This area is a major hub for freight, logistics, and commercial trucking throughout Southern California. You’re moving goods through here, and we’re here to make sure your fleet stays compliant while you do it.
Our testers are CARB credentialed. That means they’ve passed the official training and certification required by the state. We use CARB-certified OBD devices. We handle CTC-VIS registration, compliance fee payment, and test submission. You don’t have to figure out the CARB website or navigate confusing user guides. We do it.
First, your truck needs to be registered in the CTC-VIS database. If it’s not already in there, we handle that. You’ll also need to pay the annual compliance fee—$31.18 per vehicle. This isn’t something we charge. It’s a state fee that goes directly to CARB.
Once that’s squared away, we perform the OBD emissions test using CARB-certified diagnostic equipment. We’re plugging into your truck’s onboard diagnostics system and pulling data directly from the emissions control equipment. This isn’t a visual inspection. It’s a technical diagnostic that checks whether your diesel particulate filter, NOx sensors, and other emissions components are functioning correctly.
If your truck passes, we submit the results to CARB electronically. You’re done. Your compliance is recorded, and you’re good until your next test is due. If something comes back flagged, we’ll tell you exactly what needs repair. No runaround. No guessing.
The whole process is designed to minimize your downtime. You’re not sitting around for hours. We get you in, tested, and back on the road. That’s the point.

California’s Clean Truck Check program applies to all diesel trucks over 14,000 lbs GVWR operating in the state. Doesn’t matter if your truck is registered in California or out of state. If it’s on California roads, it needs to comply.
For trucks with 2013 or newer engines, you’re required to get OBD testing every six months starting in 2025. That frequency increases to quarterly testing in October 2027. CARB isn’t easing up on enforcement—they’re tightening it. Roadside monitoring devices and automated license plate readers have been active since January 2023. They’re scanning trucks in real time and flagging non-compliant vehicles.
Here in Rosemead and across Southern California, heavy-duty trucks are everywhere. This region handles massive freight volume, and CARB knows it. That’s why enforcement is heavy in areas like this. You’re not flying under the radar.
Our service is built specifically for the 2013+ diesel trucks that require OBD testing. If your truck is older or under 14,000 lbs, this isn’t the right service. But if you’re running newer heavy-duty equipment, this is exactly what you need to stay legal and avoid the headaches that come with non-compliance.
If your truck fails, you’ll get a detailed report showing exactly what triggered the failure. Usually, it’s a malfunctioning emissions component—diesel particulate filter, NOx sensor, or something similar. You’ll need to get that repaired by a qualified mechanic.
Once the repair is done, you’ll need to come back for a retest. CARB requires proof that the issue was fixed and that your emissions system is working correctly. You can’t just ignore it. A failed test means your truck isn’t compliant, and that opens the door to fines and registration problems.
The key is addressing it quickly. The longer you wait, the more risk you’re taking. Get the repair done, get retested, and get back to compliant status. That’s the only way forward.
Right now, if your truck has a 2013 or newer engine and weighs over 14,000 lbs, you need testing every six months. That’s twice a year. Starting in October 2027, that requirement jumps to four times a year—quarterly testing.
This applies whether your truck is registered in California or not. If you’re operating in the state, you’re subject to California’s rules. CARB tracks compliance through the CTC-VIS system, and they cross-reference that with roadside monitoring data.
Missing a test isn’t just a paperwork issue. It can trigger registration holds, fines, and roadside enforcement actions. You need to stay on schedule. Set reminders, plan ahead, and don’t let it slip. The penalties for falling behind aren’t worth it.
Yes. If your truck operates in California, it needs to comply with CARB regulations—even if it’s registered in another state. This catches a lot of interstate operators off guard, but the law is clear. California roads, California rules.
That means you need to register your truck in the CTC-VIS database, pay the annual compliance fee, and complete the required emissions testing. CARB doesn’t care where your plates are from. They care whether your truck meets California’s emissions standards while it’s operating here.
Roadside enforcement actively targets out-of-state trucks because they know compliance rates are lower. Don’t assume you’re exempt. If you’re hauling freight through California regularly, get compliant. It’s not optional, and the fines for non-compliance are steep.
CTC-VIS stands for Clean Truck Check Vehicle Information System. It’s CARB’s database for tracking heavy-duty vehicle compliance. Every truck subject to the Clean Truck Check program needs to be registered in this system.
Once you’re registered, CTC-VIS tracks your testing history, compliance fee payments, and any enforcement actions. CARB uses this data to monitor whether your fleet is staying compliant. If you’re not in the system or your records aren’t up to date, you’re flagged as non-compliant.
We handle CTC-VIS registration and data submission as part of our service. You don’t need to log in, figure out the interface, or deal with the bureaucracy. We make sure your trucks are in the system and your test results are properly recorded. That’s one less thing you have to manage.
The actual OBD test takes about 15 to 30 minutes. We’re plugging into your truck’s diagnostic system, pulling emissions data, and running it through CARB-certified equipment. It’s not a lengthy process.
That’s a huge difference from traditional manual inspections, which can take one to three hours and cost you $300 to $900 in downtime per vehicle. OBD testing is faster, more accurate, and less disruptive to your operations.
You’re not leaving your truck with us for half a day. You’re getting in and out quickly. For fleet operators managing multiple vehicles, that efficiency adds up. Less downtime means more time on the road, and that’s what keeps your business moving.
CARB can fine you up to $10,000 per vehicle per day for non-compliance. That’s not a typo. Per vehicle, per day. If you’re running a fleet, those fines can escalate fast.
On top of that, CARB can place a registration hold on your truck. That means you can’t renew your registration until you’re compliant. Your truck is effectively grounded. You can’t legally operate it, and you’re losing money every day it sits.
Roadside enforcement is also a real threat. CARB uses emissions monitoring devices and license plate readers to identify non-compliant trucks. If your truck gets flagged, you’ll receive a Notice to Submit to Testing. Ignoring that notice makes things worse. The penalties stack up, and CARB doesn’t back down. Stay compliant. It’s the only way to avoid this mess.
