Corona sits at one of the busiest freight interchanges in Southern California. Every day, heavy-duty diesel trucks move through the I-15/SR-91 corridor hauling loads from the Ports of Los Angeles and Long Beach into the Inland Empire and CARB knows it. SR-91 is one of the most actively monitored commercial trucking corridors in the state. Running a non-compliant truck on that route isn’t a gray area.
What we do at All SMOG Motors is remove the operational friction from staying compliant. We come to your yard, your dock, or wherever your trucks are staged in the Corona area. You don’t pull a driver off a route. You don’t lose a load. The OBD test gets done on-site, results go directly into CARB’s CTC-VIS database, and your compliance record updates without you touching a single form.
For fleet managers running distribution operations near Prologis facilities or along the 92879 and 92882 corridors, that kind of efficiency matters. And for owner-operators running daily loads out of western Riverside County, it means your truck stays on the road instead of sitting in a line at a shop that wasn’t built for this test.
All SMOG Motors is a CARB-credentialed emissions testing company that does exactly one thing: Clean Truck Check OBD testing for model year 2013 and newer heavy-duty trucks with a GVWR over 14,000 pounds. That’s not a limitation that’s the point. When a tester only does one thing, we do it right.
We serve Corona and the surrounding western Riverside County area, including Norco, Eastvale, Jurupa Valley, and Temescal Valley. Our credentials are publicly listed on CARB’s website, our OBD equipment holds CARB Executive Order approval, and every test result we submit goes directly into the CTC-VIS system electronically. You can verify all of that before you ever call us.
There are no general smog checks happening here, no passenger cars, no older opacity-test vehicles. Just the specific test your 2013-or-newer heavy-duty truck requires performed by a specialist who knows the system, the equipment, and what a valid submission actually looks like.
It starts with a simple booking. You tell us where your trucks are located in the Corona area your fleet yard, your distribution dock, your staging lot and we schedule a time to come to you. No drop-off, no tow, no rerouting a driver. The truck stays exactly where it needs to be.
When we arrive, we connect our CARB-certified OBD device to your truck’s diagnostic port. The device reads the onboard emissions data directly from the truck’s system this is the test that CARB requires for model year 2013 and newer heavy-duty vehicles. The process is straightforward and doesn’t take long. Once the data download is complete, we review the results on-site.
If the truck passes, we submit the results electronically and directly into CARB’s CTC-VIS database right then. There’s no manual step for you to handle, no portal to log into later, no risk of a missed submission. CARB transmits passing VINs to the DMV nightly, so your compliance record updates quickly. Keep in mind that DMV records typically take three to five business days to reflect the change, so if you’re working against a registration renewal deadline in Riverside County, booking a few days ahead of that window is the smarter move.

The Clean Truck Check program established under California’s SB 210 and enforced by CARB applies to diesel and alternative fuel heavy-duty vehicles with a GVWR over 14,000 pounds that operate on California public roads. If your truck is model year 2013 or newer and it’s running freight in or through Corona, it falls under this requirement. That includes trucks registered out of state.
Testing is currently required twice per year. Starting October 1, 2027, OBD-equipped vehicles move to quarterly testing four times per year. For fleet operators managing multiple trucks out of Corona’s distribution corridors, that shift is significant. Getting a reliable testing relationship in place now, before that frequency doubles, is the kind of planning that prevents compliance emergencies later.
There’s also a detail that catches a lot of operators off guard: paying the $31.18 annual CARB compliance fee does not satisfy the testing requirement. The fee and the OBD emissions test are two separate obligations. Both are mandatory. A truck that has paid the fee but hasn’t submitted a passing test is still non-compliant and under South Coast AQMD jurisdiction, which covers all of western Riverside County including Corona, enforcement attention in this region is high and getting higher. Fines can reach $10,000 per vehicle per day. We handle the test the part that actually closes the compliance loop.
If your truck is model year 2013 or newer and has a GVWR over 14,000 pounds, yes it’s subject to the Clean Truck Check requirement regardless of where in California it’s based. Being headquartered or garaged in Corona doesn’t change the obligation. What matters is whether the vehicle operates on California public roads, and if it does, CARB requires it to test.
This applies to both California-registered trucks and out-of-state trucks operating in the state. So if you’re running loads through the SR-91 or I-15 corridor out of a Corona yard and your truck meets those two criteria 2013 or newer, GVWR over 14,000 lbs you need a passing OBD test submitted to CARB’s CTC-VIS system. We can come directly to your location in Corona to handle that.
A failed test means the truck’s onboard diagnostic system flagged an active emissions-related fault typically a stored fault code that the system hasn’t cleared. It doesn’t always mean something is catastrophically wrong, but it does mean the truck cannot be submitted as compliant until the underlying issue is addressed and the system reads clean.
After a failure, the truck will need to be repaired by a qualified diesel mechanic, and then retested. We perform the OBD test we’re not a repair shop, so the repair work itself would go to a diesel service provider in the Riverside County area. Once the repair is done and the fault codes are cleared, we can return to your location in Corona for the retest and submit the passing result directly to CARB’s CTC-VIS database. The goal is to get your truck back into compliant status as quickly as possible so it stays on the road.
A Notice to Submit to Testing gives you 30 calendar days from the date on the notice to submit a passing Clean Truck Check result to CARB. That’s 30 days total not 30 days to start looking for a tester. The clock is running from the moment the notice is issued.
For truck operators in Corona and western Riverside County, the most important thing you can do when you receive one of these notices is act immediately. Don’t wait until day 25 to start calling around. All SMOG Motors is a mobile, CARB-credentialed tester that specializes specifically in 2013-and-newer heavy-duty OBD trucks we’re not a general smog shop trying to fit your truck into a schedule built for passenger cars. If you’re under a 30-day NST window, call us, tell us your situation, and we’ll work to get your truck tested and submitted into CTC-VIS as quickly as possible.
CARB publishes a publicly accessible list of credentialed Clean Truck Check testers on their website at arb.ca.gov. Before you book anyone including us you can look up the tester’s name or company and confirm their credential status directly with CARB. It takes about two minutes and it’s the single most important verification step you can take.
Why does it matter? Because a test performed by an uncredentialed tester is not a valid Clean Truck Check submission. CARB won’t accept it. Your truck will still show as non-compliant in the CTC-VIS system, your DMV registration hold won’t clear, and you’ll have paid for a test that doesn’t count. In a market like Corona where over 1,600 trucking companies are operating and the demand for compliance testing is high, not every operator advertising this service has the credentials to back it up. All SMOG Motors is listed. Verify it yourself.
Yes, and that’s exactly the kind of situation our mobile model is built for. If you’re managing a fleet of heavy-duty trucks staged at a distribution yard, a 3PL facility, or your own lot in the Corona area, we can work through multiple vehicles in a single visit. Each truck gets its own OBD data download using our CARB-certified equipment, and each passing result is submitted individually and directly into CARB’s CTC-VIS database.
This matters especially for fleet managers running operations tied to Corona’s logistics and distribution sector. Pulling trucks one at a time to an off-site testing facility creates scheduling headaches, driver downtime, and gaps in your compliance calendar. Having a credentialed tester come to your yard and work through your fleet on-site keeps your trucks where they need to be and your compliance records current. If you’re thinking ahead to the 2027 quarterly testing mandate when testing frequency doubles establishing this kind of on-site testing relationship now makes that transition significantly easier.
A DMV registration hold tied to Clean Truck Check non-compliance is cleared through the CTC-VIS system, not directly at the DMV counter. Once we perform your OBD test and submit a passing result into CARB’s CTC-VIS database, CARB transmits your compliant VIN to the DMV nightly. That means your DMV record will update but it typically takes three to five business days after submission for the change to fully reflect in DMV’s system.
If you’re in Corona and trying to renew your registration immediately after a passing test, that processing window is worth knowing about. The test being done doesn’t mean DMV’s screen shows green the same day. Plan for that gap. In the meantime, keeping a copy of your CTC-VIS submission confirmation is useful documentation if you’re questioned about compliance status before the DMV record catches up. We submit results electronically and directly there’s no manual step on your end that could delay the process.
