Hear from Our Customers
You’re not dealing with registration holds. You’re not scrambling to fix a truck that’s been flagged by CARB. You’re not explaining to a customer why their delivery is late because your semi is sitting in a shop somewhere.
When your Clean Truck Check is done right, your trucks stay registered. Your business keeps running. You’ve got documentation proving compliance if you ever get pulled over or audited.
And you’re not guessing about whether you’re meeting California’s heavy-duty vehicle compliance requirements. You know. Because the test was done by a CARB credentialed tester using certified equipment, and it’s on file with the state. That’s what compliance actually looks like—no drama, no downtime, no expensive surprises.
If you’re running 2013 or newer trucks over 14,000 pounds GVWR in California, this isn’t optional anymore. It’s required. And getting it done in Indio means you’re not driving hours out of your way to find someone who can actually perform the test.
All SMOG Motors is a CARB certified testing facility in Indio, serving the Coachella Valley’s commercial trucking community. We’re credentialed to perform Clean Truck Check testing on heavy-duty diesel vehicles—the kind of testing that became mandatory in California as of October 2024.
We’re not new to emissions regulations. We’ve been helping truck owners and fleet operators navigate California’s compliance requirements for years, and we’ve seen what happens when testing isn’t done right. Retests cost time and money. Registration holds shut down operations.
Indio sits at the center of a region that depends on trucking—agriculture, logistics, construction. If your trucks aren’t compliant, your business stops. We’re here because this area needs local access to certified CARB emissions testing, and because we understand what’s at stake when a truck can’t pass.
First, we confirm your truck qualifies. This service is only for trucks that are model year 2013 or newer and have a gross vehicle weight rating over 14,000 pounds. If your truck is older or lighter, it’s not subject to Clean Truck Check requirements—and we’ll tell you that upfront.
Once we’ve confirmed eligibility, we connect to your truck’s onboard diagnostics system using CARB certified OBD testing equipment. We’re checking emissions data that your truck’s computer has been collecting. The test looks at how your diesel engine is performing and whether it’s meeting California’s emissions standards for heavy-duty vehicles.
If your truck passes, we submit the results directly to CARB. You’ll get documentation showing compliance, and your vehicle stays in good standing with the DMV. If something comes back flagged, we’ll walk you through what needs attention and what your options are for getting it fixed.
The whole process is straightforward. You’re not waiting days. And because you can submit a passing test up to 90 days before your compliance deadline, you’ve got time to address any issues without your registration getting held up.
Ready to get started?
You’re getting a CARB certified emissions test performed by a credentialed tester using equipment that meets California Air Resources Board standards. That’s not marketing language—it’s a legal requirement. If the test isn’t done by someone with the right credentials and the right tools, it doesn’t count.
You’re also getting compliance documentation that goes straight to the state. When your test is complete and passing, that information is submitted to CARB’s database. Your truck stays registered. Your business keeps moving.
Here in Indio and throughout the Coachella Valley, a lot of trucks are running agriculture routes, hauling equipment for construction, or moving goods through logistics networks. Those operations don’t stop for compliance issues—or at least, they shouldn’t have to. Having local access to certified Clean Truck Check testing means you’re not losing half a day driving to another county just to get a test done.
And if you’re an owner-operator or running a small fleet, you need to know costs upfront and timelines that actually work. We’re not here to upsell you on services your truck doesn’t need. If your vehicle qualifies and passes, you’re done. If it doesn’t pass, we’ll explain what’s wrong in plain terms so you can make a decision about next steps.
Your truck needs a Clean Truck Check if it’s model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds. That’s the threshold California set when the regulation went into effect in October 2024.
If your truck is older than 2013, it’s not subject to this requirement. If it’s under 14,000 pounds GVWR, same thing—it doesn’t apply. This is specifically for newer heavy-duty diesel trucks that are equipped with onboard diagnostics systems.
A lot of people assume all commercial vehicles need this test, but that’s not accurate. The rule targets a specific category of trucks based on weight and model year. If you’re not sure whether your vehicle qualifies, bring us your registration or VIN and we’ll tell you right away whether you’re subject to the requirement or not.
Starting in 2025, most trucks subject to this regulation will need testing twice a year—that’s the semi-annual requirement. But 2024 was a transition year, and if you already completed a one-time test during that period, your next test is based on your compliance deadline going forward.
CARB assigns compliance deadlines based on your vehicle’s last three VIN digits. You’ll receive a Notice to Submit to Testing from the state, and you’ve got 30 days from that notice to submit a passing test. Miss that window and your registration can be held up.
The good news is you can submit a passing test up to 90 days before your deadline. That gives you a buffer if your truck doesn’t pass on the first try and needs repairs. It also means you can plan ahead instead of scrambling at the last minute when a notice shows up.
If your truck doesn’t pass, you’ll need to get the issue fixed and then retest. The test results will show what triggered the failure—usually it’s an emissions system problem or a fault code that indicates something isn’t working the way it should.
You’ve still got time to address it, especially if you tested early. Remember, you can submit a passing test up to 90 days before your deadline, so if you catch a problem early, you’re not under the gun to get it repaired immediately.
Once repairs are made, you come back for a retest. If it passes the second time, we submit those results to CARB and you’re compliant. If you ignore the failure and don’t retest, that’s when you run into bigger problems—registration holds, removal from CARB’s compliance database, and potential fines if you’re caught operating a non-compliant vehicle.
It has to be done by a CARB credentialed tester using CARB certified equipment. You can’t just take your truck to any shop and expect the test to count. The state is very specific about who’s allowed to perform these tests and what tools they have to use.
That’s why finding a certified facility matters. If the test isn’t done right, it doesn’t get submitted to CARB’s system, and you’re still out of compliance even though you paid for a test. You’d have to do it again somewhere else—and you’ve just wasted time and money.
All SMOG Motors is a CARB certified testing facility in Indio. We’ve got the credentials and the equipment to perform Clean Truck Check testing that actually counts. And because we’re local, you’re not driving all over Riverside County trying to find someone who can do the test correctly.
The cost depends on the specifics of your truck and the testing required, but we’ll give you a clear price before we start. There’s no point in surprising you with fees after the fact—you need to know what you’re paying upfront so you can plan accordingly.
As for time, the actual test doesn’t take long. We’re connecting to your truck’s OBD system and pulling emissions data that’s already stored in the computer. You’re not sitting around for hours. Most tests are completed the same day, and if everything checks out, the results get submitted to CARB right away.
Where things take longer is if your truck doesn’t pass and needs repairs. That’s out of our hands—it depends on what’s wrong and how quickly you can get it fixed. But the test itself? It’s straightforward, and we’re not going to waste your time dragging it out.
If you miss your compliance deadline, the DMV can place a hold on your vehicle registration. That means you can’t renew your registration until you submit a passing test. Your truck also gets removed from CARB’s compliance database, which creates problems if you’re ever stopped or inspected.
And if you keep operating a non-compliant truck, you’re risking enforcement action. CARB can issue penalties that run thousands of dollars per vehicle per day. That’s not a scare tactic—it’s what the regulation allows them to do when trucks aren’t meeting emissions requirements.
The easiest way to avoid all of that is to test early. You’ve got a 90-day window before your deadline to submit a passing result. Use it. If your truck passes, you’re done. If it doesn’t, you’ve still got time to fix the problem and retest without your registration getting flagged. Waiting until the last minute is how people end up with trucks that can’t legally operate.
