The I-10 is one mile south of La Verne’s border. The I-210 runs right through the northern edge of the city. If your trucks are moving freight through this corridor whether you’re staging out of the Brackett Air Business Park on McKinley Avenue, running loads for Fairplex events, or operating out of one of La Verne’s business park facilities downtime is not an option. A DMV registration hold doesn’t just slow paperwork. It stops a truck that should be on the road.
What Clean Truck Check compliance actually gives you is operational continuity. Your truck stays registered, stays legal, and stays moving. The Pomona Valley’s air quality challenges the San Gabriel Mountains trap pollution blown in from the LA basin, and La Verne sits right at that eastern end of the funnel are exactly why CARB built this program. Diesel emissions on these corridors are a real issue here, not an abstract one. That context matters, because enforcement reflects it.
Mobile OBD testing means you don’t pull a truck off a load to drive it somewhere. A credentialed technician comes to your yard, your lot, or your dock runs the OBD data download, submits results directly to CARB’s CTC-VIS database, and you’re done. No portal. No guesswork. No compliance gap.
All SMOG Motors is a CARB-credentialed HD I/M testing operation that works exclusively with 2013-and-newer OBD-equipped heavy-duty trucks. That’s our entire focus not passenger cars, not pre-2013 opacity testing, not a generalist shop that added commercial trucks to a menu. If your truck falls under CARB’s Clean Truck Check program, this is specifically what we do.
Our credentials are publicly listed on CARB’s own website at arb.ca.gov. You can verify that before you book and you should. We use only CARB-certified OBD test devices with Executive Order approval, which means your test is valid the first time. We serve Los Angeles County, including La Verne and the surrounding Pomona Valley cities San Dimas, Claremont, Pomona, and the commercial corridors along both I-10 and I-210.
La Verne’s business community is experienced and doesn’t have patience for providers who don’t know the program. Neither do we. You get a tester who knows the regulations, shows up on schedule, and submits results correctly.
You contact All SMOG Motors and confirm your truck qualifies model year 2013 or newer, GVWR over 14,000 pounds. If it fits that profile, we schedule a mobile appointment at your location. For La Verne operators, that typically means your yard, your bay at Brackett Air Business Park, a staging area off McKinley Avenue, or wherever your truck is parked when you need the test done. You don’t reposition the truck. We come to it.
On the day of the appointment, a CARB-credentialed technician connects a CARB-certified OBD device to your truck’s diagnostic port and pulls the emissions data directly from the ECU. The process is fast the data download itself takes a matter of minutes. What matters is that the equipment is CARB-approved and the tester is credentialed, because a test performed with the wrong equipment or by an uncredentialed provider doesn’t count. Your truck would still be flagged as non-compliant, and the fee would be wasted.
After the test, we submit results electronically to CARB’s CTC-VIS database directly, immediately after the test. CARB transmits compliant VIN data to DMV nightly, and DMV records typically update within three to five business days. You don’t log into any portal. You don’t submit anything manually. It’s handled.

Every Clean Truck Check appointment with All SMOG Motors includes a CARB-certified OBD data download using Executive Order-approved equipment, direct electronic submission to CARB’s CTC-VIS database, and confirmation that your truck’s compliant status is on its way to DMV. You don’t receive a printout to mail in or a file to upload yourself we handle the submission at the time of the test.
This service applies only to trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. These are the OBD-equipped vehicles CARB’s Clean Truck Check program specifically targets. If your truck is older or lighter, this program doesn’t apply to it and we won’t tell you otherwise. For La Verne fleet operators running multiple trucks with different registration dates, we can coordinate testing across your vehicles so compliance deadlines don’t stack up on you at once.
One thing worth knowing as you plan ahead: CARB currently requires OBD-equipped trucks to test twice per year. Starting October 1, 2027, that increases to four times per year quarterly. If you’re managing a fleet out of La Verne’s business park corridor or operating out of the McKinley Avenue industrial area, building a reliable testing relationship now is the practical move before that frequency doubles. The 90-day advance testing window CARB allows also gives you room to test early, create a repair window if your truck needs work, and stay ahead of your deadline rather than chasing it.
If your truck is a 2013 or newer model with a GVWR over 14,000 pounds and it operates on California public roads, then yes CARB’s Clean Truck Check program applies regardless of where it’s based. Being stationed at Brackett Air Business Park on McKinley Avenue in La Verne doesn’t change the requirement. The program is triggered by the vehicle’s model year, weight rating, and operation on California roads not by the type of facility it operates out of.
For operators at Brackett Field running cargo, warehouse, or import/export vehicles, the practical reality is that these trucks are typically on the road regularly, which means they’re exactly the vehicles CARB is targeting. The good news is that we offer mobile testing, so you don’t have to pull a truck off a job to get tested. We come to you whether that’s a bay at the business park, a staging area on McKinley, or wherever your truck is when the appointment is scheduled.
A failed test means your truck’s emissions data came back outside CARB’s acceptable thresholds typically because of an active fault code or a system that’s reporting a malfunction to the ECU. It does not mean your truck is immediately impounded or taken off the road on the spot, but it does mean you’re still non-compliant until a passing test is submitted. You’ll need to address whatever triggered the failure and retest.
The important thing to understand is that CARB allows you to test up to 90 days before your compliance deadline. That advance window exists precisely to give you time to deal with a failure get the repair done, clear the fault code, and retest before your actual deadline hits. If you wait until the last minute and fail, you’re in a much tighter spot. For La Verne operators who depend on their trucks for daily operations along the I-10 and I-210 corridors, testing early is the move that keeps you in control of the timeline instead of reacting to it.
No, and this is one of the most common misunderstandings in the program. The annual compliance fee $31.18 per vehicle for 2025 and the OBD emissions test are two completely separate requirements. Paying the fee does not substitute for testing, and it will not clear a DMV registration hold if your truck hasn’t submitted a passing emissions test. Many truck owners in the Pomona Valley have paid the fee on time and then discovered at DMV renewal that their registration is still blocked because the test was never done.
Think of it this way: the fee keeps your account active in CARB’s system. The test is what actually proves your truck’s emissions are within compliance. Both are required. If you’re not sure whether your truck’s test is on file with CARB, you can check your vehicle’s status in the CTC-VIS portal using your VIN or contact us and we can help you figure out where you stand before scheduling a test.
Right now, OBD-equipped vehicles under CARB’s Clean Truck Check program are required to submit a passing test twice per year semi-annually. That requirement is tied to your truck’s DMV registration renewal cycle, so the specific deadlines vary by vehicle. The key is knowing when your truck’s compliance window opens and making sure you test within it.
What’s coming that every La Verne fleet operator should already be planning for: starting October 1, 2027, the testing frequency increases to four times per year quarterly. That’s a significant jump in scheduling demand, especially if you’re managing multiple trucks with different compliance dates. Building a relationship with a reliable mobile tester now, before the quarterly requirement kicks in, means you’re not scrambling to find someone when four deadlines per year start running simultaneously. La Verne’s growing commercial base including the business park expansion and increased activity around the new Metro A Line station area means more trucks in this corridor will be navigating that same shift.
A Notice to Submit to Testing often called an NST is a formal notice from CARB indicating that your truck has been identified as a potential high emitter and is required to submit a passing Clean Truck Check test. Once you receive one, you have exactly 30 calendar days from the date on the notice to submit a passing test. Not 30 business days 30 calendar days. That clock moves fast, especially if your truck needs any repairs before it can pass.
If you’re operating trucks out of La Verne and you receive an NST, the first call to make is to a CARB-credentialed tester who can get to your location quickly. Waiting to see if the notice goes away, or assuming the annual compliance fee covers it, are both mistakes that lead to fines which can reach up to $10,000 per vehicle per day or trucks being pulled from service entirely. We offer mobile testing, which means we can respond to time-sensitive situations without requiring you to reroute a truck that’s in the middle of a job.
Yes. If an out-of-state registered truck is a 2013 or newer model with a GVWR over 14,000 pounds and it operates on California public roads, CARB’s Clean Truck Check requirements apply to it. California’s program does not exempt vehicles based on their registration state it’s based on where the vehicle operates. This is relevant for La Verne operators who work with carriers, subcontractors, or vendors whose trucks are registered outside California but regularly run loads through the Pomona Valley on I-10 or I-210.
The practical implication is that if you’re a fleet manager or business owner in La Verne coordinating vehicles that aren’t California-registered, those trucks still need to be in compliance when they’re operating here. CARB enforcement along the I-10 corridor one of the nation’s most actively monitored freight routes is not something to assume out-of-state plates will sidestep. If you’re unsure whether a specific vehicle falls under the program, the clearest answer comes from checking the truck’s model year and GVWR against CARB’s requirements, which we’re happy to walk through with you before scheduling.
