You’re running a business, not studying California regulations full-time. But CARB doesn’t care if you missed the memo—they’ll hit you with fines up to $10,000 per vehicle per day, freeze your DMV registration, and shut down your operation until you’re compliant.
That’s where we come in. We handle clean truck check testing for heavy-duty vehicles with a GVWR over 14,000 pounds and model year 2013 or newer. We bring the test to your location in Hermosa Beach, run the diagnostics, and get you your emissions report on the spot.
No waiting in line at a testing center. No losing half a day of work per truck. You schedule the appointment, we show up with state-certified equipment, and you get back to business. If something flags during the pre-check, we’ll tell you before the official test so you’re not wasting time or money on a failure.
This isn’t about upselling you services you don’t need. It’s about keeping your fleet legal so you can keep earning.
We’ve been handling truck emissions and heavy-duty compliance in the Los Angeles area since 2005. We’re licensed and credentialed by the state of California, with CARB-certified testers who know the current regulations inside and out.
We’re also fully insured—which most mobile testers aren’t. We carry TSA clearance to work at airports and port terminals, and we’re trusted by utility companies, government agencies, and fleet operators throughout Hermosa Beach, Long Beach, Torrance, and the South Bay.
If you’re hauling freight through California or operating near the ports, you already know how strict enforcement has gotten. We’ve been helping owner-operators and fleet managers stay ahead of it for over 20 years. We’re not new to this, and we’re not learning on your dime.
First, you schedule an appointment at your yard, terminal, or wherever your truck is parked in Hermosa Beach or the surrounding area. We’ll confirm the vehicle qualifies—meaning it’s 2013 or newer and over 14,000 pounds GVWR.
When we arrive, we run a pre-check using diagnostic software to make sure your truck’s onboard systems are ready for testing. If something’s flagged as “NOT READY” or there’s a potential issue, we’ll tell you before we run the official test. That saves you from a failed result and the hassle of a retest.
Once everything checks out, we perform the CARB emissions test using the same opacity equipment the state uses—fully compliant with SAE J1667 specifications. The test itself doesn’t take long, and you get your results immediately.
If you pass, you’re done. If you need a retest, we handle that too. We’ll also help you with CTC-VIS registration if you’re not already set up in the system. No extra runaround, no hidden fees for account setup like some other providers charge.
Ready to get started?
California’s Clean Truck Check program requires semi-annual testing for most heavy-duty diesel trucks with 2013 or newer engines. That’s twice a year, every year, with no grace period if you miss the deadline. Starting in 2027, OBD-equipped vehicles will need testing four times a year.
If you operate in or through California—even if you’re based out of state—you’re subject to these rules. CARB uses roadside monitoring devices and automated license plate readers to flag potential high emitters. If your truck gets flagged, you have 30 days to submit proof of testing or face penalties.
The compliance fee is $32.13 per test as of January 2026, and that’s on top of the testing cost. But the real expense is what happens if you’re not compliant: registration holds that prevent you from renewing your plates, fines that stack up daily, and the lost income from trucks sitting idle.
We serve Hermosa Beach and the greater Los Angeles area, including fleets operating near the ports in Long Beach and San Pedro. If you’re running drayage, construction equipment, or long-haul trucks through Southern California, you’re in our service area. We come to you, test on-site, and make sure you’re covered before the state comes knocking.
Yes, if you operate in California. CARB regulations apply to any heavy-duty truck operating on California roads, regardless of where it’s registered.
Out-of-state carriers get caught off guard by this all the time. You might be fully compliant with federal EPA standards, but California has its own rules—and they enforce them aggressively. If your truck has a 2013 or newer engine and a GVWR over 14,000 pounds, and you’re driving through or operating in California, you need to be enrolled in the Clean Truck Check program and tested semi-annually.
CHP can pull you over for a roadside inspection. If you’re not compliant, they can issue citations and put your truck out of service until you fix it. Don’t assume your home state registration covers you here—it doesn’t.
Testing costs vary depending on the provider, but you’re typically looking at $50 to $190 per vehicle in the Los Angeles area. That doesn’t include the state compliance fee, which is $32.13 as of 2026.
What you really need to factor in is downtime. If you drive your truck to a testing center, you’re losing one to three hours per vehicle—which can cost you $300 to $900 in lost productivity. Mobile testing eliminates that.
We come to your location in Hermosa Beach, test on-site, and get you the results immediately. No waiting rooms, no taking trucks off jobs, no burning half a day per vehicle. Some providers also charge extra for help with CTC-VIS account setup—up to $75 in some cases. We include that support at no additional cost.
If your truck fails, you’ll need to address whatever triggered the failure—usually an emissions issue or an onboard diagnostic system that’s not ready—and then retest.
We run a pre-check before the official test to catch potential problems early. If something’s flagged, we’ll let you know so you can fix it before it becomes a failed test on your record. That saves you time and the cost of an unnecessary retest.
Once the issue is resolved, we’ll come back and retest at no additional charge for the first retest. Most failures are related to the OBD system not being “ready,” which can happen after recent repairs or a battery disconnect. Sometimes it just needs a drive cycle to reset. We’ll walk you through what needs to happen so you’re not guessing.
Right now, most heavy-duty trucks with 2013 or newer engines need testing twice a year—that’s semi-annual testing. Starting in 2027, if your truck is OBD-equipped, that increases to four times a year.
The state doesn’t send reminders. It’s on you to track your testing schedule and submit results on time. If you miss a deadline, you risk a registration hold, which means you can’t renew your plates until you’re compliant. And if you’re flagged during a roadside check or by an automated plate reader, you’ll have 30 days to submit proof of testing.
We work with fleets in Hermosa Beach and throughout the South Bay to stay on top of testing schedules. If you’ve got multiple trucks, we can set up a recurring schedule so nothing slips through the cracks. It’s a lot easier to stay compliant than to dig yourself out of a violation.
No. Our CARB compliance testing is specifically for heavy-duty trucks with a GVWR over 14,000 pounds and a model year of 2013 or newer. That’s what the Clean Truck Check program covers, and that’s what we’re equipped and certified to test.
If your truck is older than 2013, it falls under a different program—the Periodic Smoke Inspection Program (PSIP)—which has different requirements and testing procedures. We don’t handle that.
And if your vehicle is under 14,000 pounds, it’s not subject to the same heavy-duty emissions rules. You’d need a standard smog check, which is a completely different process. We focus exclusively on the newer, heavier trucks that are subject to CARB’s strictest regulations. If your fleet includes vehicles outside that range, we’re not the right fit—and we’ll tell you that upfront rather than waste your time.
Yes. Before you can get tested, your truck needs to be registered in California’s Clean Truck Check Vehicle Information System (CTC-VIS). This is a one-time setup, but it’s required before any testing can happen.
A lot of fleet operators get stuck here because the registration process isn’t intuitive, and the state doesn’t make it easy. You need your VIN, engine details, and registration information, and if anything’s entered wrong, it can delay your ability to test.
We help with CTC-VIS registration at no extra charge. Some mobile testers charge up to $75 just to walk you through the account setup—we don’t. If you’re not registered yet, we’ll guide you through it so you’re ready to test. And if you’ve already got an account but haven’t used it in a while, we’ll make sure everything’s current before we run the test. It’s part of the service.
