You’re running a business, not a compliance department. But California doesn’t care about your delivery schedule when your truck fails to meet Clean Truck Check requirements. The DMV will block your registration renewal. CHP can cite you at roadside inspections. And those fines start at $1,000 and climb to $75,000 per vehicle, per day.
That’s not a scare tactic. That’s the reality for any heavy-duty diesel truck over 14,000 pounds operating in California without proper CARB emissions testing. If your truck is model year 2013 or newer, you’re required to test through the Clean Truck Check program. Miss your deadline and you’re grounded until you fix it.
We handle CARB compliance testing for commercial trucks in Pomona so you can focus on what actually makes you money. Our CARB credentialed testers run the required OBD scans, submit results directly to the state database, and make sure your compliance status is locked in before your deadline hits. You get documentation. You stay legal. Your trucks keep moving.
We operate right here in Pomona, CA, in the heart of Southern California’s logistics corridor. We’re not a general smog shop trying to figure out heavy-duty compliance on the fly. We specialize in CARB emissions testing for commercial trucks that actually need it—the big rigs moving freight through the Inland Empire, in and out of the ports, across state lines.
Pomona sits at the center of one of the busiest distribution networks in the country. You’re close to the Ports of Los Angeles and Long Beach, connected to major highways, and surrounded by warehouses and logistics operations. That means CARB enforcement is everywhere. Automated license plate readers, remote emissions monitoring, roadside inspections at border crossings—they’re watching.
We’ve built our operation around the specific requirements for trucks model year 2013 and newer with a GVWR over 14,000 pounds. That’s the threshold where California’s Clean Truck Check rules kick in, and that’s where most shops stop understanding what you actually need.
You bring your truck to our facility in Pomona. We’re set up to handle heavy-duty vehicles, so you’re not trying to squeeze into a parking lot designed for sedans. Our CARB credentialed testers connect a certified OBD testing device to your truck’s engine system. This isn’t a visual inspection or a tailpipe test—it’s a data scan that pulls emissions information directly from your engine’s computer.
The scan checks for fault codes, monitors emission control system performance, and verifies that everything meets California Air Resources Board standards. If your truck passes, we submit the results directly to the CTC-VIS database that same day. The state updates your compliance status, and you’re good for your next six-month cycle.
If something flags during the test, we’ll tell you exactly what needs attention. You have a 90-day window before your compliance deadline to get repairs done and retest. That buffer matters because it gives you time to fix issues without scrambling at the last minute or facing a registration hold. Once repairs are complete, you come back, we retest, and submit passing results before your deadline.
You walk away with documentation showing your compliance status. No guessing. No waiting weeks to find out if the state received your results. You know where you stand.

This service applies specifically to diesel and alternative fuel trucks with a gross vehicle weight rating over 14,000 pounds and a model year of 2013 or newer. If your truck doesn’t meet both of those criteria, this isn’t the test you need. California’s Clean Truck Check program targets OBD-equipped heavy-duty vehicles, and that’s exactly what we’re certified to handle.
You get a full OBD emissions scan performed by a CARB credentialed tester using state-approved testing equipment. We’re not cutting corners or using generic scan tools. The device we use is specifically certified by the California Air Resources Board for Clean Truck Check compliance testing. That certification matters because results from non-approved equipment won’t be accepted by the state.
We submit your passing test results directly to the CTC-VIS database. You don’t have to figure out how to upload documents or navigate a state portal. We handle the submission, and the state updates your compliance record in their system. That’s what prevents registration holds and keeps you clear during roadside inspections.
Pomona’s location puts you right in the middle of California’s most heavily monitored freight corridors. Trucks moving through here are subject to CHP inspections, ALPR monitoring, and remote emissions checks at border crossings and port entries. Your compliance status needs to be airtight, and that starts with proper testing and documentation.
If your truck fails the Clean Truck Check emissions test, you’ll get a detailed report showing exactly what triggered the failure. Most failures come from fault codes in the OBD system—things like malfunctioning sensors, emission control system issues, or engine performance problems that affect emissions output.
You’re not immediately penalized for a failed test as long as you’re still within your compliance window. California gives you up to 90 days before your official deadline to get repairs done and retest. That buffer is built into the system specifically so you have time to address issues without facing fines or registration holds.
Once you complete the necessary repairs, bring your truck back and we’ll run the test again. If it passes, we submit the results to the state and your compliance status gets updated. The key is not waiting until the last minute. If you test early and fail, you have time to fix it. If you wait until your deadline and fail, you’re looking at immediate consequences.
CARB compliance testing costs vary depending on the specific service and your truck’s configuration, but you’re typically looking at a few hundred dollars for the test itself. That’s separate from California’s annual compliance fee, which is around $31 for 2025 and must be paid to the state before your deadline.
Compare that cost to the alternative. A single day of non-compliance can trigger fines between $1,000 and $75,000 per vehicle. A DMV registration hold grounds your truck completely, which means lost revenue for every day it’s not on the road. A roadside citation from CHP adds penalties and potential out-of-service orders.
The testing cost is a known expense you can budget for. The penalties for skipping it are not. Most owner-operators and fleet managers we work with in Pomona treat this as a standard operating cost—like fuel, insurance, or maintenance. It’s required to do business in California, and the cost of compliance is always lower than the cost of enforcement.
Yes. If your truck is registered outside California but operates within the state, you’re still subject to Clean Truck Check requirements. California doesn’t give out-of-state operators a pass. In fact, CARB specifically conducts roadside inspections at border crossings, ports, and railyards to catch non-compliant trucks entering from other states.
The same rules apply: if your truck is model year 2013 or newer with a GVWR over 14,000 pounds, you need to comply with California’s emissions testing program. That means getting tested by a CARB credentialed tester and having your results submitted to the state database.
Out-of-state trucks face the same penalties as California-registered vehicles—fines up to $75,000 per day, registration holds if you try to register in California later, and roadside citations during inspections. Pomona’s proximity to major freight routes and ports makes it a high-enforcement area. If you’re running loads through Southern California regularly, you need to be compliant before you cross the state line.
Starting in 2025, trucks subject to Clean Truck Check must test every six months. That’s two compliance deadlines per year, spaced six months apart. For 2024, the requirement was annual—just one test to get into the system. But moving forward, you’re looking at semiannual testing.
Your specific deadline depends on your vehicle identification number and when you first entered the program. The state assigns compliance dates based on your VIN, and those dates don’t change year to year. You’ll have the same two deadlines every year, so once you know your schedule, you can plan around it.
The 90-day testing window is critical here. You can submit passing test results up to 90 days before your deadline. That means if your compliance date is June 1st, you can test as early as March 1st and still have it count. Testing early gives you a cushion for repairs if something fails, and it keeps you from scrambling when your deadline is days away.
Yes. The actual testing process doesn’t take long—usually under an hour depending on your truck and whether we find any issues during the scan. If your truck passes, we submit results to the state database that same day. You’re in, you’re tested, you’re documented, and you’re back on the road.
Same-day service depends on availability, so calling ahead helps. We handle heavy-duty trucks in Pomona regularly, but if you show up during a busy period without an appointment, you might wait. Scheduling in advance guarantees we have a bay ready and a tester available when you arrive.
If your truck fails the test, same-day completion isn’t possible because you’ll need repairs before retesting. But you’ll leave with a clear breakdown of what failed and what needs to be fixed. Once repairs are done, schedule a retest and we’ll get you compliant. The faster you address failures, the more time you have before your deadline and the less risk you carry.
Bring your vehicle registration and any previous compliance documentation if you have it. We need to verify your truck’s VIN, model year, and GVWR to confirm it falls under Clean Truck Check requirements. Your registration covers most of that information.
If you’ve tested before, having your prior compliance records helps us check your deadline and see your testing history. But it’s not required—we can pull your compliance status from the state database using your VIN. The state tracks everything once you’re in the system.
You don’t need to bring proof of your annual compliance fee payment, but make sure it’s paid before your deadline. The fee and the test are separate requirements. Even if you pass the emissions test, you’re not compliant until the state receives your annual fee. Most operators pay the fee online through CARB’s portal well before their testing date to avoid any last-minute issues.
