You’re running trucks in California. That means CARB diesel compliance isn’t optional—it’s the cost of doing business here. And starting January 2025, if your heavy-duty vehicles aren’t tested and compliant, the DMV can freeze your registration.
That’s not a warning. That’s how it works now.
Our Clean Truck Check service in Lawndale gets your 2013 or newer trucks over 14,000 pounds GVWR tested by CARB credentialed professionals. You get your results submitted directly to the state. You avoid the fines, the downtime, and the stress of wondering if you’re legal. Testing can be done up to 90 days before your deadline, so you’re not scrambling last minute trying to find a shop that knows what they’re doing.
This isn’t about upselling you services you don’t need. It’s about keeping your operation compliant so you can focus on the actual work.
We serve the Lawndale area with CARB certified emissions testing for heavy-duty vehicles. We’re not new to this. We understand the regulations, the deadlines, and what’s at stake when your trucks need to stay on the road.
Lawndale sits in the heart of LA County’s trucking corridor. You’ve got the 405, the 91, and access to the ports. That means heavy-duty vehicle compliance isn’t just paperwork—it’s survival. We’re here because this community runs on logistics, and we know what happens when one truck gets sidelined.
We don’t oversell. We don’t overcomplicate. You bring in your 2013 or newer truck that weighs over 14,000 pounds, we run the CARB HD I/M testing using the equipment and standards the state requires, and you get results you can trust.
You schedule your Clean Truck Check appointment. Bring your truck in—again, this applies only to model year 2013 or newer with a GVWR over 14,000 pounds. If your truck doesn’t meet both of those criteria, this test doesn’t apply.
We connect to your truck’s onboard diagnostics system using CARB-approved testing equipment. The system reads emissions data, checks for fault codes, and verifies your vehicle meets California’s heavy-duty emissions standards. This isn’t a visual inspection or a tailpipe test—it’s an electronic diagnostic process that follows the CARB HD I/M protocol.
Once the test is complete, results get transmitted directly to the DMV. You’ll know whether you passed, and if there’s an issue, we’ll walk you through what needs to happen next. Most trucks that are properly maintained pass without issue. If yours doesn’t, you’ll need repairs before retesting, but at least you’ll know before the state flags your registration.
You also need to pay your annual compliance fee—$31.18 for 2025—but that’s separate from the testing itself. We can point you in the right direction for that.

This is CARB emissions testing for California CARB compliant heavy-duty trucks. You’re required to test semi-annually starting in 2025—that’s twice a year. By 2027, some OBD-equipped vehicles will need testing four times a year. The rules are getting stricter, not looser.
Here in Lawndale and across LA County, heavy-duty trucks make up a small percentage of vehicles but produce over half the smog pollution. CARB’s cracking down because the air quality impact is massive. That’s why penalties are steep—up to $10,000 per vehicle per day if you’re caught operating without compliance.
Our service applies to trucks used in commerce, including drayage trucks, construction vehicles, delivery fleets, and long-haul semis operating in California. If you’re an owner-operator or manage a fleet, this affects you. Out-of-state trucks operating here? You’re not exempt.
The testing window opens 90 days before your compliance deadline. That gives you time to get it done without the panic. And if you’re managing multiple trucks, spacing out your tests throughout the year makes a lot more sense than trying to squeeze everything in at the last second.
If your truck is model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds, yes. This is a state-mandated program under CARB regulations, and it’s not optional if you’re operating in California.
The program started October 2024, with the first compliance deadlines hitting January 1, 2025. If you don’t get tested and submit passing results, the DMV can place a registration hold on your vehicle. That means you can’t renew your registration, and technically, you can’t legally operate the truck on California roads.
This applies whether you’re based in California or just passing through for work. If the truck operates here and meets those specs, it needs testing. Lighter trucks and older models aren’t part of this program—yet.
Starting in 2025, most heavy-duty trucks need testing twice a year. That’s semi-annual compliance, which is a big shift from the old system.
If your truck is OBD-equipped, the testing frequency increases even more. By 2027, those vehicles will need testing four times a year. CARB’s phasing this in gradually, but the direction is clear: more frequent checks, tighter oversight.
You can submit your test results up to 90 days before your deadline, so plan ahead. Waiting until the week before puts you at risk if something comes back flagged. Get it done early, and you’ve got time to address any issues without losing work days.
If your truck doesn’t pass, you’ll need to get the issues repaired and then come back for a retest. The test results will show what triggered the failure—usually it’s a fault code or emissions reading that’s out of spec.
You can’t just ignore it. A failed test means you’re not compliant, and if your deadline passes without a passing result on file, the DMV will block your registration. That’s not a maybe—it’s automatic once the system flags your vehicle.
The good news is most well-maintained trucks pass without trouble. If yours has been regularly serviced and isn’t throwing check engine lights, you’re probably fine. But if you’ve been putting off repairs or your truck’s been running rough, get that handled before you test. It’ll save you time and money in the long run.
Testing fees vary depending on the shop, but you’re generally looking at somewhere between $60 and $150 per test. That’s separate from the state compliance fee, which is $31.18 for 2025.
Some shops charge more if you’ve got a fleet and need multiple trucks done at once. Others offer mobile testing, which costs extra but saves you the trip. We keep our pricing straightforward—no hidden fees, no surprises when you show up.
What you don’t want to do is skip the test to save money. The penalties for non-compliance start at $10,000 per vehicle per day. One missed deadline costs you way more than a year’s worth of testing ever would. This is one of those expenses that’s a lot cheaper to stay on top of than to ignore.
No. This specific program—the Clean Truck Check under CARB’s HD I/M regulations—only applies to trucks that are model year 2013 or newer and over 14,000 pounds GVWR.
If your truck is older than 2013, it’s not part of this testing requirement. That doesn’t mean it’s exempt from all California emissions rules—there are other programs and standards that might apply—but it’s not subject to the Clean Truck Check.
Same goes for lighter trucks. If your vehicle is under 14,000 pounds, even if it’s a 2013 or newer model, this test doesn’t apply. You might still need a regular smog check depending on the vehicle type, but that’s a different process entirely. Don’t pay for a service your truck doesn’t legally require.
You need a CARB credentialed tester. Not every smog shop is certified to perform Clean Truck Check testing—this requires specific equipment, training, and state approval.
We’re credentialed and equipped to handle heavy-duty emissions testing for 2013 and newer trucks over 14,000 pounds. We’ve got the diagnostic tools, the certification, and the experience with CARB’s requirements.
You can also check CARB’s public registry if you want to verify a shop’s credentials before you go. But if you’re in the Lawndale area and need testing done right, we’re here. Schedule your appointment, bring your truck in, and we’ll get you compliant without the runaround.
