You avoid registration holds at the DMV. Your trucks don’t get flagged at weigh stations or denied entry to ports and railyards. You’re not scrambling to fix a compliance issue the day before your deadline.
When your semi truck passes CARB emissions testing, you’re cleared to operate without interruption. No surprise fines. No pulled registrations. No drivers sitting idle because a vehicle got red-flagged.
This applies specifically to trucks that are model year 2013 or newer with a gross vehicle weight rating over 14,000 pounds. If your fleet fits that profile, you’re required to submit passing emissions compliance tests for every deadline starting January 1, 2025. Miss it, and the consequences stack up fast—registration blocks, daily fines that can hit $10,000 per vehicle, and operational restrictions that cost you more than just money.
We bring the test to your location in Covina, CA. You don’t lose a day driving to a testing facility. Our credentialed testers handle the inspection, submit results electronically to the CARB database, and you get confirmation that you’re good to go. It’s straightforward, and it keeps your business moving.
All SMOG Motors specializes in CARB compliant testing for the exact vehicles California regulates the hardest—heavy-duty diesel and alternative fuel trucks. We’re not a general smog shop trying to figure out commercial vehicle rules on the fly.
We serve fleet operators, owner-operators, and logistics companies throughout Covina and the surrounding Los Angeles County area. This region has one of the highest concentrations of commercial trucking in the state, which means CARB enforcement is active, consistent, and unforgiving.
Our testers are CARB-credentialed, trained on the latest compliance protocols, and equipped to handle the specific requirements for 2013 and newer trucks. We’ve seen what happens when deadlines get missed or tests get submitted incorrectly. We make sure that doesn’t happen to you.
First, we confirm your truck qualifies—model year 2013 or newer, GVWR over 14,000 pounds. If it does, we schedule a time to come to your yard or location in Covina. You don’t need to take the vehicle anywhere.
Our credentialed tester arrives with the equipment needed to perform a full CARB emissions compliance test. This isn’t a visual inspection. It’s a diagnostic check that connects to your truck’s onboard diagnostics system and verifies emissions performance against California standards.
Once the test is complete, results are submitted electronically to the CTC-VIS database—the state system that tracks compliance. If your truck passes, you’re cleared for that compliance period. If it doesn’t, we’ll walk you through what needs to be addressed and offer a retest once repairs are made.
You can submit your test up to 90 days before your compliance deadline, which gives you a buffer if something needs attention. Most operators in Covina schedule early to avoid last-minute issues, especially during peak enforcement periods when CARB ramps up roadside monitoring and automated license plate scanning.
The annual compliance fee for 2025 is $31.18 per vehicle, paid separately to CARB. We handle the testing and submission—you handle the registration and fee payment through the state portal.

Every CARB compliant smog check we perform includes mobile service at your location, which means no lost drive time and no pulling trucks off routes. You stay operational while we handle the compliance work.
We perform the full diagnostic emissions test required by California law for heavy-duty vehicles. That includes connecting to your truck’s OBD system, running the compliance protocol, and verifying that emissions fall within acceptable limits for your vehicle’s model year and weight class.
Results are transmitted directly to the CARB database the same day. You’ll receive confirmation that your test has been submitted and logged under your vehicle’s VIN. This is critical—if the state doesn’t see a passing test on file by your deadline, your registration gets blocked and penalties start accruing immediately.
In Covina and throughout LA County, enforcement is aggressive. CARB uses roadside emissions monitoring devices and automated license plate readers to flag high-emission vehicles. If your truck gets flagged, you’ll receive a Notice to Submit to Testing, and you’ll have just 30 days to get a passing test on file. We’ve worked with operators who’ve been through that process, and the timeline is tight.
We also provide guidance on navigating the CTC-VIS portal if you’re new to the system or need help with registration. It’s not the most intuitive platform, and mistakes during setup can delay compliance confirmation.
If you operate a heavy-duty truck with a gross vehicle weight rating over 14,000 pounds and it’s model year 2013 or newer, you’re required to submit passing CARB emissions compliance tests. This applies to diesel trucks, hybrid trucks, and alternative fuel vehicles registered in California or operating in the state regularly.
The requirement went into effect for all compliance deadlines on or after January 1, 2025. That means if your truck’s compliance deadline falls after that date, you must have a passing test on file with CARB or your vehicle will be flagged for non-compliance.
This doesn’t apply to older trucks or lighter vehicles. If your truck is model year 2012 or earlier, or if the GVWR is under 14,000 pounds, you’re not subject to this specific testing requirement. But if you’re running newer, heavier equipment—especially in and out of ports, railyards, or freight terminals around Covina—you need to stay on top of this.
The test itself varies by provider, and some offer free retests if your truck doesn’t pass the first time. The state compliance fee for 2025 is $31.18 per vehicle annually, paid directly to CARB when you register in the CTC-VIS system.
You’re required to submit a passing emissions compliance test once per compliance year. Your specific deadline depends on your vehicle’s VIN and the schedule CARB assigns. Most operators get notified well in advance, but you can also check your deadline by logging into the CTC-VIS portal.
You can submit your test up to 90 days before your deadline, which gives you a window to address any issues if the truck doesn’t pass. Waiting until the last minute is risky—if you fail and need repairs, you might not have time to retest before the deadline hits. And once you’re past due, the consequences are immediate. Registration holds go into effect, and fines start at $1,000 but can reach $10,000 per vehicle per day depending on the violation.
If your truck doesn’t pass, you’ll get a report that outlines what triggered the failure. Most failures are related to emissions system malfunctions, sensor issues, or problems with the diesel particulate filter or exhaust components.
You’ll need to get those issues repaired before you can retest. Once repairs are done, we can come back out and run the test again. Some testing providers, including us, offer a free retest within a certain timeframe if the truck was tested with us originally.
What you can’t do is ignore it. A failed test still needs to be followed up with a passing one before your compliance deadline. If you miss that deadline, your registration gets blocked and you’re looking at penalties that add up daily. CARB doesn’t issue grace periods for mechanical issues—your deadline is your deadline, and the state expects you to plan accordingly.
We bring the test to you. That’s one of the biggest advantages of working with a mobile CARB testing provider in Covina—you don’t lose half a day driving to a facility, waiting in line, and driving back.
Our credentialed tester shows up at your location with all the diagnostic equipment needed to perform the full compliance test on-site. We can test one truck or an entire fleet in a single visit, depending on your schedule and how many vehicles are due.
This is especially useful for operators running tight schedules or managing multiple trucks with staggered deadlines. You keep your equipment in service, we handle the testing and submission, and you get confirmation that everything’s filed correctly with the state. It’s faster, more convenient, and eliminates the downtime that comes with traditional smog check locations.
If you’ve never submitted a CARB compliance test before, you probably aren’t registered yet. The CTC-VIS system is the state database that tracks emissions testing for heavy-duty vehicles, and you need an account to view deadlines, submit tests, and pay compliance fees.
Setting up an account isn’t complicated, but it does require your vehicle information, VIN, registration details, and some navigation through CARB’s portal. If you’re not sure whether you’re registered or need help getting set up, we can walk you through it.
Once you’re in the system, you’ll be able to see your compliance deadlines, check the status of submitted tests, and confirm that your trucks are cleared. If you’re operating in Covina or anywhere in California with heavy-duty trucks that fall under the 2013+ and 14,000+ pound requirements, getting registered should be a priority. The state won’t send you reminders if you’re not in the system—they’ll just flag your vehicle when the deadline passes.
If you receive a Notice to Submit to Testing, it means your truck was flagged by CARB’s roadside emissions monitoring or license plate scanning system. The state identified your vehicle as potentially high-emission and is requiring you to prove compliance within 30 days.
That’s a hard deadline. You need to schedule a CARB emissions test, pass it, and have the results submitted to the CTC-VIS database within that 30-day window. If you don’t, your vehicle is considered non-compliant and penalties begin immediately.
This notice usually comes after your truck was scanned during normal operation—at a weigh station, on the highway, or near a port or railyard. CARB has been using this technology heavily since 2023, and it’s become one of the primary enforcement tools in areas like Los Angeles County. If you get the notice, don’t wait. Contact us in Covina, get the test done, and make sure it’s submitted on time.
