If your truck operates in California and has a GVWR over 14,000 pounds, you need proof of CARB compliance. That’s not a suggestion anymore. As of January 1, 2024, it’s mandatory.
Non-compliance means fines up to $10,000 per vehicle, per day. It means DMV registration holds. It means your trucks could be banned from operating in California if emissions issues aren’t fixed within 30 days. You’re not just risking a citation – you’re risking your ability to generate revenue.
The testing requirement applies specifically to diesel, hybrid, and alternative-fuel trucks that are model year 2013 or newer. If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this regulation doesn’t apply to you. But if it does apply, you need to submit a passing clean truck check within 90 days of your compliance deadline.
We handle CARB certified smog check testing for heavy-duty vehicles in La Puente. You get OBD emissions testing performed by CARB credentialed testers, and we transmit your results directly to CARB’s system. You walk away with documentation that keeps your trucks on the road and your business moving.
We operate in La Puente, right in the middle of one of California’s busiest commercial transportation corridors. We’re not a general smog shop trying to figure out heavy-duty compliance on the fly.
We focus exclusively on CARB emissions testing for trucks that fall under the 2013-and-newer, 14,000+ GVWR requirement. That means we know the testing protocols, the submission windows, and what CARB actually looks for when they review your results.
Our testers are CARB credentialed, which means they’ve completed the required training and passed CARB’s certification exam. We use CARB-validated OBD testing equipment, and your test results go directly into CARB’s CTC-VIS database. You’re not dealing with paperwork delays or wondering if your submission went through. It’s handled.
You schedule your clean truck check within 90 days before your compliance deadline. That’s the submission window CARB allows, so timing matters.
When you arrive, we connect to your truck’s onboard diagnostics system and run the OBD emissions test. This isn’t a visual inspection or a tailpipe test. CARB requires OBD testing for 2013 and newer trucks, which pulls data directly from your vehicle’s emissions control systems.
If your truck passes, we transmit the results to CARB’s CTC-VIS database immediately. You get documentation showing your test was completed and submitted. That documentation is what protects you from fines, registration holds, and enforcement action.
If your truck doesn’t pass, you’ll know exactly what the issue is. You’ll have 30 days to get the emissions problem fixed before CARB takes enforcement action. We can’t fix the truck, but we can tell you what needs attention so you’re not guessing.
The whole process takes about 30 minutes if your truck passes. You’re in, you’re tested, you’re documented, and you’re back on the road.

CARB compliance isn’t just about passing one test. You need to be registered in CARB’s TRUCRS database, you need periodic emissions testing based on your compliance deadline, and you need proof that everything was submitted correctly.
La Puente sits in Los Angeles County, which has some of the strictest air quality enforcement in California. CARB pursued over 8,000 enforcement cases in 2022 and collected more than $21.5 million in citations. They’re not issuing warnings – they’re issuing fines. And those fines compound daily.
Your compliance deadline is based on your truck’s registration renewal date. If your registration renews in January or July, your testing window is already open. You can submit a passing test up to 90 days before your deadline, but not earlier.
The test itself checks your truck’s emissions control systems through the OBD port. CARB wants to see that your diesel particulate filter, NOx sensors, and other emissions equipment are functioning correctly. If any of those systems throw a code or fail to respond, your truck won’t pass.
Once you pass, your TRUCRS certificate gets updated automatically. That’s the documentation DMV checks when you try to renew your registration. Without it, you’re blocked. With it, you’re clear.
This service only applies to semi trucks and heavy-duty vehicles with a GVWR over 14,000 pounds that are model year 2013 or newer. If your truck doesn’t meet both of those criteria, you don’t need this test.
You have 30 days to fix the emissions issue and get retested. CARB doesn’t give you a pass for trying – they give you a limited window to make it right.
The OBD test will show exactly which emissions system failed. It might be a faulty NOx sensor, a clogged diesel particulate filter, or a software issue. You’ll need to take your truck to a repair shop that can address the specific problem.
Once the repair is done, you come back for another clean truck check. If it passes the second time, we submit those results to CARB and you’re compliant. If you don’t fix it within 30 days, CARB can ban your truck from operating in California and hit you with daily fines until it’s resolved.
Yes, if your truck operates in California. CARB compliance applies to all heavy-duty trucks operating in the state, regardless of where they’re registered.
That means if you’re an out-of-state fleet running routes through California, your 2013-and-newer trucks with a GVWR over 14,000 pounds need to be tested and registered in CARB’s TRUCRS database. The regulation doesn’t make exceptions for interstate carriers.
You’ll need to register your truck in the TRUCRS system, pay the required fees, and submit passing emissions tests based on your compliance schedule. If you don’t, you’re subject to the same fines and enforcement action as California-registered trucks. CARB has pursued major out-of-state carriers for non-compliance, including Amazon Logistics, which paid $3.2 million in settlements.
You can submit a passing test up to 90 days before your compliance deadline. Any earlier than that, and CARB won’t accept it.
Your compliance deadline is tied to your truck’s DMV registration renewal date. If your registration renews in January, your testing window opens in October. If it renews in July, your window opens in April.
The 90-day window gives you time to schedule the test, address any issues if your truck doesn’t pass, and get everything submitted before the deadline. But you can’t test too early and bank the results for later. CARB’s system won’t accept tests submitted outside that window, which means you’d have to pay for another test closer to your deadline.
No. The CARB emissions testing requirement only applies to trucks that are model year 2013 or newer.
If your truck was manufactured in 2012 or earlier, it’s not subject to the periodic emissions testing mandate, even if it has a GVWR over 14,000 pounds. CARB chose 2013 as the cutoff because that’s when federal emissions standards required onboard diagnostics systems on heavy-duty trucks.
However, your 2012 truck still needs to comply with other CARB regulations, including the Truck and Bus Rule, which requires certain engine upgrades or replacements based on the truck’s age and weight class. Those are separate requirements with different deadlines and enforcement mechanisms. But you don’t need the clean truck check emissions test we’re talking about here.
Regular smog checks are for passenger vehicles and light-duty trucks under 14,000 pounds. CARB compliance testing is specifically for heavy-duty trucks over 14,000 pounds GVWR that are model year 2013 or newer.
The testing process is completely different. A standard smog test might include a tailpipe emissions check and a visual inspection. CARB compliance testing for heavy-duty vehicles uses OBD diagnostics to check your truck’s emissions control systems directly.
The results also go to different places. Regular smog check results go to the Bureau of Automotive Repair. CARB compliance test results go to CARB’s CTC-VIS database, which is part of the TRUCRS system. DMV checks that database when you try to renew your heavy-duty truck’s registration. If you don’t have a passing test on file, your registration gets blocked and you can’t legally operate the truck in California.
CARB can fine you up to $10,000 per vehicle, per day for non-compliance. Those fines compound daily, which means a week of non-compliance could cost you $70,000 for a single truck.
On top of that, DMV will place a hold on your registration, which means you can’t renew it until you’re compliant. You’ll also face additional fines of $1,000 or more per day, per vehicle from DMV for operating without valid registration.
If you don’t fix emissions issues within 30 days of a failed test, CARB can ban your truck from operating in California entirely. That’s not a temporary suspension – it’s a full operational ban until you prove the truck is fixed and compliant. For fleets running California routes, that means lost revenue, missed deliveries, and potential contract violations. CARB collected over $21.5 million in enforcement penalties in 2022, and they’re not slowing down.
