When your DMV registration gets blocked or a Notice to Submit to Testing shows up, the clock starts immediately. A 30-day deadline doesn’t leave much room for scheduling delays, shop drop-offs, or providers who aren’t sure how the CTC-VIS submission process works. What you need is someone who shows up, runs the test on CARB-certified equipment, and submits the results electronically before they leave your property.
Highgrove sits right on the edge of one of the busiest freight corridors in Southern California. Owner-operators and small fleet managers working out of yards near the I-215 can’t afford to reposition a truck to a fixed testing location during a live haul cycle. Mobile service isn’t a convenience here it’s the only option that makes operational sense. We built our process around that reality.
Once the test is submitted to CARB’s CTC-VIS database, your compliant status updates immediately on CARB’s end. The DMV record clears within 3 to 5 business days. That timeline doesn’t change whether you’re based in Highgrove, running routes through Riverside County, or staging near the I-10 interchange and we’ll tell you exactly what to expect before we leave your lot.
All SMOG Motors is a CARB-credentialed mobile testing company serving Los Angeles and Riverside Counties. We focus exclusively on Clean Truck Check OBD testing for model year 2013 and newer heavy-duty vehicles with a GVWR over 14,000 pounds. That’s the whole job. No passenger cars, no older opacity-method trucks, no general diagnostics just the specific compliance test that your truck is required to pass under California’s HD I/M program.
Our credentials are publicly listed on CARB’s official “Available for Hire Credentialed Testers” page at arb.ca.gov. You can verify that before you book, and we’d encourage you to. In a market that’s seen a surge of new testing providers since enforcement started in October 2024, knowing your tester is legitimate isn’t optional an invalid test from an uncredentialed provider leaves your truck non-compliant and your deadline unchanged.
Highgrove is unincorporated Riverside County there’s no city hall here, no local permit layer, and no municipal code to navigate. Your compliance obligation runs straight through CARB and the state. That’s exactly the level we operate at, and it’s the only level that matters for your registration.
You call or book online, tell us where your truck is located, and we schedule a time to come to you your yard, your job site, your staging lot, wherever the truck is sitting. We don’t ask you to bring it anywhere. For operators working out of properties near Center Street or along the western industrial fringe off the I-215, that means zero repositioning time and no interruption to your schedule.
When we arrive, we connect our CARB-certified OBD test device directly to your truck’s ECU and download the emissions data. The equipment holds a CARB Executive Order that’s the state certification that makes the test result valid and acceptable for compliance. A professional-grade scanner without that certification doesn’t count, and your truck is still flagged as non-compliant. Ours counts.
After the test, we submit your results electronically to CARB’s CTC-VIS database before we leave. You don’t log into a portal, you don’t mail anything in, and you don’t wonder if the submission went through. CARB’s system updates immediately. The DMV side takes 3 to 5 business days to reflect the change we tell you that upfront so you’re not calling the DMV the next morning expecting an instant update. From booking to compliant status, the process is straightforward, and you’ll know exactly where things stand at every step.

The Clean Truck Check program applies to diesel and alternative-fuel heavy-duty vehicles that are model year 2013 or newer with a GVWR over 14,000 pounds. If your truck doesn’t meet both of those criteria model year AND weight this program doesn’t apply to you. We only perform OBD-method testing under the HD I/M regulation. We don’t test older trucks using the opacity method, and we don’t test anything under that weight threshold. That boundary exists so we can do this one thing exceptionally well.
Right now, OBD-equipped trucks in California require semi-annual testing twice per year. Starting October 1, 2027, that frequency moves to quarterly, meaning four tests per year. For fleet operators in Riverside County managing multiple vehicles with different compliance deadlines, that escalation is worth planning for now. Establishing a reliable testing provider before the frequency doubles gives you one less thing to scramble on when the schedule tightens.
One detail that catches a lot of Highgrove-area operators off guard: paying the $31.18 annual CARB compliance fee does not satisfy your testing requirement. The fee and the emissions test are two completely separate obligations. You can pay the fee and still have a registration hold if the test hasn’t been submitted. On the flip side, we allow you to submit a passing test up to 90 days before your compliance deadline which gives fleet managers a real planning window if they want to get ahead of it. If your truck is registered out of state but operating regularly on California roads near the I-215 corridor, you’re subject to the same requirements as any California-registered vehicle.
If your truck is model year 2013 or newer and has a GVWR over 14,000 pounds, yes it’s subject to California’s Clean Truck Check requirement regardless of where in the state it operates. Highgrove is unincorporated Riverside County, which means there’s no city-level exemption or local variance. The requirement comes straight from CARB and applies uniformly across California public roads.
The program became fully enforced for periodic testing on October 1, 2024, with the first compliance deadline hitting January 1, 2025. If your truck was in service before that and hasn’t been tested yet, it’s likely already flagged in CARB’s system. The fastest way to find out where you stand is to check your VIN in the CTC-VIS portal or call us and we can walk you through it before we schedule anything.
A registration hold from CARB means your truck hasn’t passed a Clean Truck Check test within the required window. The hold doesn’t lift until a passing test result is submitted to CARB’s CTC-VIS database by a credentialed tester using certified equipment. Paying the annual compliance fee won’t clear it that’s a separate obligation, and a lot of truck owners in the Highgrove and Riverside area have paid the fee thinking it resolved the issue. It doesn’t.
Once we come to your location, run the test, and submit the results to CTC-VIS, CARB’s records update the same day. The DMV side takes 3 to 5 business days to reflect the change. That’s not a delay on our end it’s just how the state data transfer works between CARB and DMV. We’ll confirm submission before we leave your lot so you know the clock is running on that 3-to-5-day window.
A Notice to Submit to Testing means CARB has flagged your vehicle as a potential high emitter usually because your truck was screened by a Roadside Emissions Monitoring Device on a California highway. The I-215 corridor that runs directly west of Highgrove is exactly the kind of high-volume freight route where these devices are deployed. If you received one, you have 30 calendar days from the notice date to submit a passing test to CARB’s CTC-VIS system.
Thirty days sounds like enough time until you’re trying to find a credentialed tester who can get to you quickly. That’s not the moment to call a general smog shop and hope they handle heavy-duty OBD testing. We specialize in this exact scenario we schedule fast, we come to your location, and we submit results the same day. Don’t sit on the notice. The fine exposure for non-compliance can reach $10,000 per vehicle per day.
Yes, and for fleet operators in the Riverside County area, that’s usually the most efficient way to handle it. If you’re managing two or more 2013-or-newer heavy-duty trucks with GVWRs over 14,000 pounds, we can schedule a single visit to your location and test all of them back to back. Each truck gets its own individual OBD test and its own separate submission to CTC-VIS the results are vehicle-specific and tied to each VIN.
This matters especially as the testing frequency increases. Currently, you’re looking at semi-annual testing twice per year per truck. Starting October 2027, that moves to quarterly. If you have five trucks on different compliance deadlines, coordinating individual trips to a fixed testing location four times a year per vehicle becomes a real administrative burden. Scheduling multi-truck visits at your yard is a practical way to manage that before it becomes a problem.
Yes. CARB’s Clean Truck Check requirement applies to any qualifying vehicle operating on California public roads, regardless of where it’s registered. If your truck is a 2013-or-newer model with a GVWR over 14,000 pounds and it’s running freight through the Inland Empire on the I-215, the I-10, the SR-60, or any other California road it’s subject to the same testing requirements as a California-registered vehicle.
This catches a lot of interstate operators off guard, particularly owner-operators who are based in Highgrove or the surrounding Riverside area but have trucks registered in Nevada, Arizona, or another state. CARB’s enforcement doesn’t distinguish by registration state it distinguishes by where the vehicle operates. If you’re not sure whether your specific truck falls under the program, the best starting point is the CTC-VIS portal or a quick call to us before your next California run.
Right now, OBD-equipped heavy-duty trucks in California require semi-annual testing two passing tests per year. That’s the current enforcement standard following the October 2024 full rollout of the Clean Truck Check program. Each test needs to be performed by a CARB-credentialed tester using certified OBD equipment, and the results have to be submitted electronically to CARB’s CTC-VIS database to count toward compliance.
Starting October 1, 2027, the frequency escalates to quarterly four tests per year for OBD-equipped vehicles. For owner-operators and small fleet managers in the Highgrove area who are already managing tight schedules on the I-215 freight corridor, that’s a meaningful increase in compliance overhead. Getting a reliable testing provider in your contact list now before that change takes effect means you won’t be scrambling to find someone credentialed when the testing windows tighten. The 90-day early submission window CARB allows also gives you some flexibility to test ahead of each deadline rather than right at it.
