Montebello isn’t a city where trucks are a convenience they’re how business gets done. The City of Montebello officially describes itself as a center for the trucking and specialty vehicle industry, and that’s accurate. Refrigerated trucks, over-the-road haulers, and distribution rigs operate out of this city every day, running SR-60 east toward the Inland Empire, dropping south on I-710 toward the Port of Long Beach, and moving freight through one of the most heavily monitored freight corridors in the state.
When a DMV registration hold hits, it’s not a paperwork problem. It’s a business emergency. CARB’s Clean Truck Check program is now in full enforcement, and non-compliance can mean fines up to $10,000 per vehicle per day, plus a registration hold that doesn’t clear until a passing test is on file. We handle the entire process the OBD test, the CARB-certified equipment, and the direct electronic submission to CARB’s CTC-VIS database so your compliance is confirmed, not assumed.
The SR-60/SR-57 confluence near Montebello is ranked the number one freight bottleneck in California, with over 356,000 vehicles using it daily. CARB’s roadside monitoring devices actively screen trucks on these corridors. If your truck runs those routes regularly, it’s being observed. Getting compliant before a Notice to Submit to Testing lands in your mailbox is always the better move.
We don’t test passenger cars. There’s no menu of unrelated services here. Our entire business is built around 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 it. When you’re running a fleet out of a distribution yard near the I-5 corridor in southern Montebello or operating as an owner-operator in the city, you need a tester who knows this program inside and out not one who added it as a side offering.
CARB credentials aren’t self-reported. They’re issued after completing CARB’s official Tester Training Course and listed publicly on CARB’s website at arb.ca.gov. We’re on that list. The OBD equipment we use is CARB-certified meaning the test counts, it submits, and it shows up in CTC-VIS. That’s the only kind of test worth getting.
You schedule the test and tell us where your truck is a yard off the I-5 corridor, a lot near Whittier Boulevard, a staging area near the SR-60 interchange, wherever it sits. We come to you with CARB-certified OBD equipment. There’s no repositioning the truck, no waiting at a fixed location, and no lost run time.
On-site, we connect directly to your truck’s OBD port and download the emissions data from the ECU. For 2013 and newer engines, this is the required method under CARB’s HD I/M program it’s not a visual inspection or a smoke opacity test. The data captures what the engine’s own systems are reporting, and it gives CARB a real picture of how the truck is actually running.
Once the test is complete, we submit the results directly and electronically to CARB’s CTC-VIS database. You don’t log into a portal. You don’t manually upload anything. After a passing test is submitted, CARB transmits the compliant VIN to DMV overnight, and DMV records typically update within three to five business days. The whole process is straightforward and for Montebello operators running trucks on some of the most monitored freight corridors in California, straightforward matters.

Clean Truck Check applies specifically to diesel and alternative-fuel heavy-duty vehicles with a model year 2013 or newer engine and a GVWR over 14,000 pounds. If your truck meets both of those criteria and operates on California public roads even if it’s registered out of state it falls under this program. Lighter vehicles and pre-2013 trucks are not part of this program and require a different type of emissions testing.
Right now, most OBD-equipped trucks need to be tested twice per year semi-annually. Starting October 1, 2027, that increases to four times per year. For a Montebello fleet operator running ten trucks, that’s forty compliance tests annually. There’s also a separate $31.18 annual compliance fee paid directly to CARB but paying that fee does not replace the emissions test. That’s one of the most common and costly misunderstandings in this program, and it’s one that leads directly to DMV registration holds.
We serve Los Angeles County, which means Montebello-area operators whether you’re running drayage routes to the Port of Long Beach via I-710, hauling freight east on SR-60 toward the Inland Empire, or managing a specialty vehicle fleet in the city’s industrial zone have access to mobile, on-site testing without pulling a truck out of rotation. If you’ve received a Notice to Submit to Testing from CARB, you have 30 calendar days to submit a passing test. That clock doesn’t pause.
If your truck has a model year 2013 or newer engine and a GVWR over 14,000 pounds, yes it’s subject to CARB’s Clean Truck Check program. This applies whether the truck is registered in California or another state, as long as it operates on California public roads. Montebello operators running freight on SR-60, I-710, or I-5 are on corridors where CARB’s roadside monitoring equipment actively screens trucks for potential emissions issues, so the exposure to a Notice to Submit to Testing is real and ongoing.
The program moved into full periodic testing enforcement on October 1, 2024, with the first compliance testing deadline on January 1, 2025. If you haven’t tested yet and your truck meets the criteria, you’re likely already behind. The consequences of non-compliance include fines up to $10,000 per vehicle per day and a DMV registration hold that blocks renewal until a passing test is on file.
This is one of the most common points of confusion in the entire program. CARB charges a separate annual compliance fee currently $31.18 per vehicle that is billed independently of the emissions test itself. Paying that fee registers your vehicle in CARB’s system, but it does not satisfy the testing requirement. You still need a passing OBD emissions test submitted to CARB’s CTC-VIS database to be fully compliant.
Many Montebello truck owners have paid the fee on time, assumed they were good, and then received a DMV registration hold at renewal because the actual test was never completed. These are two separate obligations. We handle the test and the direct CTC-VIS submission but the annual fee is paid separately through CARB’s portal. If you’re unsure whether your test is on file, you can check your compliance status directly at CARB’s CTC-VIS system before a hold surprises you.
Currently, most OBD-equipped heavy-duty trucks are required to be tested twice per year on a semi-annual schedule. That frequency is set to increase starting October 1, 2027, when quarterly testing four times per year becomes the requirement for OBD-equipped vehicles. For a fleet operator in Montebello managing multiple trucks, that’s a significant operational shift that’s worth planning for now rather than scrambling to accommodate in two years.
One thing worth knowing: CARB allows you to submit a test up to 90 days before your compliance deadline. That means you don’t have to wait until you’re close to the wire. Scheduling proactively gives you time to address any issues before a deadline, keeps your trucks in rotation without a compliance crunch, and makes the whole process far less stressful especially if you’re managing a fleet with multiple trucks on different compliance schedules.
A Notice to Submit to Testing, or NST, means CARB has flagged your vehicle as potentially non-compliant and is requiring you to submit a passing emissions test. From the date on the notice, you have exactly 30 calendar days to get a passing test submitted to CTC-VIS. That deadline doesn’t flex. If the 30 days pass without a passing test on file, CARB can escalate enforcement which can include fines and a DMV registration hold.
For Montebello operators, the most practical response is mobile testing. Pulling a truck out of a freight run on SR-60 or off a port route on I-710 to bring it to a fixed testing location costs you time and revenue. We come to your location, test on-site with CARB-certified equipment, and submit the results directly to CTC-VIS the same day. After submission, CARB transmits the compliant VIN to DMV overnight, and DMV records typically update within three to five business days. If you’ve received an NST, contact us as soon as possible 30 days goes faster than it sounds.
Yes. CARB’s Clean Truck Check program applies to any qualifying heavy-duty vehicle operating on California public roads regardless of where it’s registered. If your truck has a model year 2013 or newer engine, a GVWR over 14,000 pounds, and it’s running routes in California, it’s subject to the program. Registration state doesn’t change that.
This is especially relevant for operators running interstate freight through Montebello’s freight corridors. Trucks coming in from Nevada, Arizona, or other western states and making regular California runs including port routes through I-710 or cross-state distribution runs on SR-60 are subject to the same testing requirements as California-registered vehicles. We can test out-of-state registered trucks on-site in Montebello the same way we test any other qualifying vehicle. The test result is submitted to CTC-VIS under the truck’s VIN, and compliance is recorded regardless of the registration state.
The OBD test itself is typically fast most tests are completed in under 30 minutes once we’re on-site and connected to the truck’s OBD port. The actual time depends on the truck, the data download speed, and whether any communication issues come up between the equipment and the ECU. In most cases, it’s not the test that takes time it’s the logistics of getting a tester to a fixed location that costs operators the most.
That’s exactly why mobile testing matters for Montebello fleets. Whether your trucks are staged near the industrial corridor off I-5, parked at a distribution yard, or sitting at a lot near the SR-60 interchange, we come to the truck. You’re not repositioning equipment, you’re not losing a run, and you’re not waiting in line at a fixed shop. We arrive, connect, test, and submit and you get confirmation that the result is in CTC-VIS before we leave. For a city where trucks are the business, that’s the only kind of testing setup that actually makes sense.
