For drayage drivers relying on the I-110 corridor, an overdue CARB filing causes real disruption. Under CARB’s enforcement rules, non-compliant trucks can be blocked from port and intermodal terminal access – which can halt your workday before it begins. Keeping your CARB compliance record active is what keeps the gates open. Our mobile testing service resolves compliance issues directly at your location. Whether your rig is parked in West Carson, staged near neighboring Carson, or positioned along the commercial borders of Torrance and Lomita, we conduct the OBD scan on-site and submit electronic results to CARB that same day. Once filed, state database updates typically clear active DMV registration holds within a few business days. Because West Carson is an unincorporated community with limited local testing facilities, our mobile service delivers a convenient, professional solution right to your door.
All SMOG Motors was built exclusively to provide dedicated mobile OBD testing under California’s Heavy-Duty I/M program. We handle 2013 and newer diesel trucks rated over 14,000 lbs GVWR, skipping light-duty vehicles and older opacity checks entirely. Our certified status is recorded under CARB Tester ID E164983 on the state’s public registry. Working with a verified tester means your electronic inspection files are accepted and processed by the state – tests from unapproved providers aren’t. We serve commercial haulers throughout the South Bay and all of Los Angeles County. From logistics yards along the Harbor Freeway to staging areas near local transit routes, we provide fast, compliant testing wherever your truck is parked.
Request an appointment online or over the phone – you’ll hear back fast, because the owner answers his own phone. We schedule visits around your active dispatching needs, meeting your truck wherever it is parked in the West Carson area. The physical inspection takes just 10 to 15 minutes. We plug CARB-approved diagnostic tools into your truck’s OBD port to gather emissions data directly from the vehicle’s computer. The truck remains stationary throughout the process, eliminating unnecessary travel. We upload test results directly to CARB’s CTC-VIS database on the same day. State data processing then helps clear DMV registration holds, typically within a few business days. Note that recently cleared fault codes or battery disconnections can result in a “Not Ready” reading, which requires brief normal driving before a valid test can be completed.

Understanding the two distinct costs involved in California compliance helps prevent unexpected surprises. Our inspection fee is $150 per truck, plus a travel fee calculated during booking based on your site location. Separately, CARB mandates an annual state compliance fee of $32.13 per vehicle. This payment is made directly to the state through the CTC-VIS online portal, and it is completely separate from our testing invoice. Both requirements must be satisfied to maintain active compliance. Qualifying diesel trucks built in 2013 or later currently follow a semi-annual testing schedule. Starting October 1, 2027, CARB will transition to a quarterly testing requirement. Not sure when your truck is due? Check our CARB deadline calculator in seconds. If you receive an urgent 30-day Notice to Submit to Testing (NST), we offer priority dispatch. Fleet operators: we test 15-40 trucks/day directly on-site, all in one visit.

It’s a real risk. Under CARB’s Clean Truck Check enforcement, non-compliant vehicles can be blocked from port and intermodal terminal access, on top of DMV registration holds. For a drayage operator, that means lost work and schedule delays. Our mobile service provides same-day OBD testing and same-day data submission. Filing your test promptly is the fastest way to keep your compliance record current and avoid problems at the gate – and if your registration is already blocked, our DMV registration hold removal service walks you through clearing it.
The testing procedure is quick and non-invasive. We connect state-approved OBD diagnostic equipment to your truck’s ECU port, read stored emissions data, and upload the results to CARB’s CTC-VIS portal. The entire visit takes 10 to 15 minutes per truck. This scan checks the operational health of onboard emissions controls on 2013 and newer diesel trucks over 14,000 lbs GVWR. It is not a mechanical overhaul or a smoke opacity test. Your vehicle stays safely parked in your yard while we handle the data capture.
Under current state rules, qualifying diesel trucks must undergo OBD testing twice per year. Deadlines align with your DMV registration renewal date and its six-month midpoint, with tests submitted within a 90-day window prior to each deadline. On October 1, 2027, CARB will switch to a quarterly testing schedule, requiring four scans annually. Partnering with a flexible mobile testing provider ensures your fleet handles this transition smoothly without extra downtime.
Our $150 fee covers the physical OBD scan, certified technician labor, and immediate electronic filing into the CTC-VIS portal. The travel fee is separate and confirmed at booking based on your location. The $32.13 annual state fee is assessed directly by CARB to maintain your vehicle’s profile in the state system. You pay this fee directly to the state through the CTC-VIS portal. Both a passing test and the state fee are necessary for complete regulatory compliance.
If the check engine light stems from an active emissions control fault, such as an issue with the DPF, EGR, or SCR system, the vehicle will fail the test. Non-emissions fault codes may not cause a failure, but active warnings should be evaluated prior to testing. We recommend diagnosing check engine lights before your appointment. Clearing codes right before a test resets internal monitors, causing a “Not Ready” result that cannot be accepted as a passing file. Resolving repairs beforehand ensures a successful inspection.
Mostly yes – but this changed in 2026, so here’s the honest picture. In January 2026, EPA disapproved the part of Clean Truck Check that applies to out-of-state-registered trucks, and federal enforcement won’t happen on those vehicles. CARB, however, has said it will keep enforcing the program under state law on all trucks operating in California – and its roadside monitoring doesn’t check your registration state before flagging you. California-registered trucks are unaffected: fully enforceable, DMV holds and all. Non-California vehicles follow a compliance schedule based on the last digit of their VIN. If you’re hauling through West Carson on out-of-state plates and aren’t sure where you stand, call us and we’ll talk it through.
