Port Truck CARB Compliance Los Angeles County & Riverside County

Two Enforcement Points. One Test Clears Both.

Most drayage operators know about DMV registration holds. Fewer realize the Port of Los Angeles and Port of Long Beach enforce CARB compliance independently — right at the terminal gate. Your truck can be turned away from a load even if the DMV hasn’t flagged it yet. That’s two separate enforcement points, and both of them can stop your day cold. The Clean Truck Check is the CARB program that covers heavy-duty vehicles with a GVWR over 14,000 pounds, model year 2013 and newer. If you’re running containers between the Inland Empire and the ports — whether you’re staged in Perris off the I-215, rolling through Rowland Heights on the SR-60, or sitting in Willowbrook two miles from the I-110 south — this test applies to your truck. And it applies whether your plates are California or out-of-state. We do one thing: Clean Truck Check. That’s it. No passenger smog, no oil changes, no distractions. When you book with All SMOG Motors, you’re getting a specialist who runs this program every day across Los Angeles County and Riverside County.

Clean Truck Check Benefits for Drayage Operators

What a Passing Test Actually Gets You

Compliance isn't just a checkbox — it's what keeps your truck earning and your port access open every single day.

Your truck clears the POLA and POLB terminal gates without a hold-up or a rejected load.

Your DMV registration stays clean — no surprise holds that ground your truck at renewal time.

Results are in the CTC-VIS system the same day, so enforcement officers and port gate inspectors see current compliance immediately.

You never deadhead to a test station — we come to your yard and have you back on the road in under 30 minutes total.

Fleet operators with five or more trucks get volume pricing and a single on-site visit — no pulling trucks from rotation one at a time.

You know exactly what you owe before the appointment — the $31.18 CARB annual compliance fee and the testing service fee are explained separately, upfront, every time.

Drayage Registry Compliance Inland Empire to Port

Riverside County Trucks Face the Same Exposure as Port-Side Fleets

There’s a common assumption that Clean Truck Check enforcement is a port-side problem — something that affects operators in Wilmington or Long Beach, not drivers based 60 miles inland in Riverside County. That assumption is wrong, and it’s expensive. If you’re running drayage out of Perris, Moreno Valley, or anywhere else along the I-215 corridor in Riverside County, your truck passes through CHP weigh stations on the way to the port. It enters POLA or POLB terminals that check the Ports Drayage Truck Registry at the gate. If your CTC-VIS record shows a missed test or an expired compliance window, you’re not getting through — regardless of where you’re based. The World Logistics Center in Moreno Valley is one of the largest logistics hubs in the Western Hemisphere. The operators running containers out of that area aren’t exempt from any of this. Neither are the fleets staging along SR-60 through Rowland Heights and City of Industry before they hit the port complex. We serve the full corridor from Riverside County to Los Angeles County because that’s the route your truck actually runs.

What the Test Covers and What We Submit

The Clean Truck Check uses an OBD scan to pull data directly from your truck’s onboard diagnostics. We check readiness monitor status, review active fault codes, and assess the condition of your Diesel Particulate Filter, Selective Catalytic Reduction system, and Exhaust Gas Recirculation valve. The scan itself takes about 15 minutes. We use only CARB-validated OBD scan devices — not every diagnostic tool qualifies under California’s technical standards, and using the wrong equipment means the test can’t be submitted. Once the scan is complete, we transmit your results directly to the CTC-VIS database. That’s the state system CARB, the DMV, and port terminal operators all reference for compliance status. There’s no paperwork for you to file, no certificate to mail in, and no waiting period. Your record updates the same day. If you’re unsure when your next test is due, use our CARB Clean Truck Check Deadline Calculator on our website. Enter your VIN or DMV expiration date and it tells you your exact 90-day testing window — so you’re not guessing or waiting until a notice arrives.

Frequently Asked Questions

Can my drayage truck be denied port access for a failed Clean Truck Check?

Yes — and this is the part most operators don’t fully understand until it happens to them. The Port of Los Angeles and Port of Long Beach both enforce CARB compliance independently at the terminal gate, separate from the DMV. That means your truck can be turned away from a load even if your registration hasn’t been flagged yet. The Ports Drayage Truck Registry cross-references CTC-VIS compliance data, and gate inspectors can and do deny entry to trucks with expired or missing test records. A short-haul drayage move in Los Angeles County and Riverside County earns roughly $350 to $700 per container. One rejected load costs more than the test itself. Getting current before you pull up to the gate is the straightforward math here.

Does the Clean Truck Check apply to out-of-state trucks operating at POLA or POLB?

It does. California’s Clean Truck Check applies to any heavy-duty vehicle with a GVWR over 14,000 pounds operating on California public roads — regardless of where the truck is registered. If you’re pulling containers at the Port of Los Angeles or Port of Long Beach and your truck is plated in Arizona, Nevada, Texas, or anywhere else, you’re still subject to the same semi-annual testing requirement. CARB and the CHP have authority to conduct roadside inspections and can flag out-of-state vehicles at weigh stations along the I-710, I-110, and I-215 corridors in Los Angeles County and Riverside County. Out-of-state operators who skip testing because they assume it doesn’t apply to them are the ones most likely to get caught at the gate.

How often does a drayage truck need to be tested under the Clean Truck Check program?

Most drayage trucks are on a semi-annual schedule — meaning twice per year. This trips up a lot of operators who assume it’s an annual requirement like a standard smog check. The testing window opens 90 days before your compliance deadline, so you have a three-month window to get it done, but that window closes whether you use it or not. Missing it doesn’t pause the clock — it puts you out of compliance. If CARB flags your vehicle as a potential high emitter and issues a Notice to Submit to Testing, you have 30 calendar days to submit a passing test. At that point you’re already behind, and the pressure is on. Testing early in your window is always the better move.

What happens if my truck fails the Clean Truck Check OBD scan?

A failed test doesn’t mean your truck is immediately grounded or that your registration is pulled on the spot. What it does mean is that your vehicle has active fault codes or readiness monitor failures that need to be addressed before you can submit a passing result. You’ll need to have the underlying issue repaired — typically something related to the DPF, SCR system, or EGR valve — and then come back for a re-test. During that window, your CTC-VIS record will reflect an incomplete or failed status, which can affect port gate access. The sooner you identify the issue, the more time you have to get it resolved without your truck sitting idle. Testing early in your compliance window gives you room to deal with a failure without missing loads.

I have a fleet of trucks staged in Riverside County — can you test all of them at once?

Yes, and that’s exactly the kind of situation we’re set up for. If you’re running a fleet of five or more trucks out of a yard in Perris, Moreno Valley, or anywhere else along the I-215 corridor in Riverside County, we come to you with volume pricing and test your entire fleet in a single visit. You’re not pulling trucks from rotation one at a time or coordinating multiple appointments across different days. One call, one visit, all trucks cleared and submitted to CTC-VIS the same day. For fleet operators, the alternative — sending trucks individually to a test station — means lost container moves for each vehicle. Mobile fleet testing at your yard is the only approach that doesn’t cost you revenue while you’re getting compliant.

What is the CARB annual compliance fee, and is it separate from the testing fee?

These are two completely separate charges, and understanding the difference saves you from confusion at payment time. The CARB annual compliance fee is $31.18 per vehicle for 2025. This is a state fee paid directly through the CTC-VIS portal — it goes to CARB, not to All SMOG Motors. It’s due on a set annual schedule regardless of when your testing window falls. The testing service fee is what you pay us to perform the OBD scan, transmit your results, and handle the CTC-VIS submission. We explain both fees clearly before your appointment so there are no surprises when it’s time to pay. If you have questions about either fee before you book, just ask — we’d rather you come in knowing exactly what to expect.
