You avoid fines up to $10,000 per vehicle per day. That’s not a scare tactic—that’s what CARB can hit you with for non-compliance.
You keep your DMV registration active. No blocks, no holds, no scrambling to get a truck back on the road because you missed a deadline.
You get documentation that proves compliance when CARB asks for it. The test results go straight into their database, and you get a certificate that shows your truck passed. If you’re operating in California with a diesel truck from 2013 or newer and a GVWR over 14,000 pounds, this isn’t optional anymore. Deadlines started January 1, 2025, and enforcement is active.
The testing window gives you 90 days before your deadline to submit a passing test. If your truck fails, you have time to make repairs and retest without missing your compliance date. That buffer matters when you’re managing a fleet or running your own rig.
We’re a CARB credentialed testing facility in Moreno Valley, CA. That credential isn’t automatic—it requires completing CARB’s official training, passing their exam with at least 80%, and maintaining certification every two years.
We’re located in the Inland Empire’s transportation corridor, where over 1,800 active carriers move freight through I-15 and I-210 daily. We understand the pressure of keeping trucks compliant in a region where downtime costs money and missed deadlines cost even more.
Our testers use CARB-approved OBD devices and follow the exact protocols CARB requires for heavy-duty vehicle compliance. We’re not guessing at the rules—we’re trained on them, and we apply them the same way CARB enforcement does.
You schedule your Clean Truck Check within 90 days of your compliance deadline. That gives you a cushion if repairs are needed.
When you arrive, we verify your truck qualifies—model year 2013 or newer for diesel engines, 2018 or newer for alternative fuel, and GVWR over 14,000 pounds. If your truck doesn’t meet those specs, this test doesn’t apply to you.
For OBD-equipped trucks, we connect to your vehicle’s onboard diagnostics using a CARB-certified device. The system checks emissions data through either SAE J1939 or J1979 protocols, depending on your engine. We’re testing what your truck is actually emitting, not just looking for a check engine light.
For non-OBD vehicles, we perform a smoke opacity test and visual inspection. Both methods follow CARB’s exact standards.
If your truck passes, we submit the results to CARB’s database and provide you with a compliance certificate. If it fails, you’ll know exactly what needs repair, and you’ll still have time before your deadline to fix it and retest.

This is semi-annual testing for trucks operating in California. If your compliance deadline falls on or after January 1, 2025, you’re required to have a passing test on file.
The test covers emissions output through OBD diagnostics for newer trucks or smoke opacity for older qualifying vehicles. We check that your emissions control systems are functioning and that your truck meets CARB’s standards for heavy-duty diesel or alternative fuel engines.
Moreno Valley sits in a high-traffic freight zone where compliance isn’t just about avoiding fines—it’s about staying competitive. With California’s local freight trucking industry valued at $17.7 billion and growing at 6.6% annually, the carriers who stay compliant are the ones who keep moving freight. The ones who don’t face registration blocks, enforcement action, and lost contracts.
Your annual compliance fee is $31.18 per vehicle as of 2025. The test itself is separate, but it’s a small cost compared to what non-compliance will run you. We’re here to make sure your trucks pass the first time and your paperwork is submitted correctly.
If your truck is a 2013 or newer diesel engine or a 2018 or newer alternative fuel engine, and it has a GVWR over 14,000 pounds, yes—you need this test if you operate in California. This applies to both in-state and out-of-state carriers.
The requirement became effective October 1, 2024, and all compliance deadlines on or after January 1, 2025, require a passing test. If your truck doesn’t meet those year and weight specs, this regulation doesn’t apply to you. But if it does, skipping the test means DMV registration blocks and potential fines up to $10,000 per vehicle per day.
You’re required to test semi-annually, meaning twice a year. CARB tracks compliance through their database, and your registration renewal depends on having a passing test on file when your deadline hits.
You get a detailed report showing exactly what failed. That might be an emissions control system malfunction, a sensor issue, or something else flagged during the OBD scan or smoke opacity test.
The good news is you have a 90-day testing window before your compliance deadline. If you test early and fail, you have time to make repairs and retest without missing your deadline. If you wait until the last minute and fail, you’re looking at a registration block and possible enforcement action.
Once repairs are done, you come back for a retest. If your truck passes, we submit the results to CARB and you get your compliance certificate. The key is not waiting until your deadline is breathing down your neck—test early so you have room to handle failures without losing your ability to operate.
For most OBD-equipped trucks, the actual test takes about 30 to 45 minutes. We’re connecting to your truck’s diagnostics, running the emissions data through CARB’s protocols, and verifying everything meets compliance standards.
Non-OBD trucks that require smoke opacity testing and visual inspections can take a bit longer, but you’re still looking at under an hour in most cases. The goal is to minimize your downtime while making sure the test is done right the first time.
If your truck passes, we handle the CARB database submission on the spot and get you your certificate before you leave. If it fails, we’ll walk you through what needs repair so you’re not guessing. Scheduling ahead helps—call us before your 90-day window closes so you’re not stuck waiting if we’re booked.
No. This specific test only applies to diesel trucks from model year 2013 or newer, or alternative fuel trucks from 2018 or newer, with a GVWR over 14,000 pounds.
If your truck is older than 2013, it’s not subject to CARB’s HD I/M testing program. That doesn’t mean it’s exempt from all emissions regulations—California has other rules for older heavy-duty vehicles—but the Clean Truck Check requirement doesn’t apply.
If you’re not sure whether your truck qualifies, check your model year and GVWR. Those two specs determine everything. Don’t assume your truck needs this test just because it’s a semi or a commercial vehicle. And don’t skip it if your truck does qualify, because CARB’s enforcement is active and the penalties are steep.
Only CARB credentialed testers who’ve completed the official training and passed the exam with at least 80%. That credential has to be renewed every two years, and it requires using CARB-approved testing equipment.
We hold that credential. We’re not just a smog shop that decided to add heavy-duty testing—we went through CARB’s training, we use their approved OBD devices, and we follow their exact testing protocols for both SAE J1939 and J1979 systems.
You can’t just take your truck anywhere and expect a valid test. If the facility isn’t CARB credentialed for heavy-duty emissions testing, the results won’t be accepted in CARB’s database, and you won’t get credit for compliance. Make sure whoever you’re working with has the credential and the equipment to do this right.
CARB can fine you up to $10,000 per vehicle per day for non-compliance. That’s not a one-time penalty—it’s daily, and it adds up fast if you’re running multiple trucks.
On top of fines, the DMV will block your registration renewal. That means your truck can’t legally operate in California until you get a passing test submitted and your compliance status is cleared. If you’re an out-of-state carrier, you’ll face restrictions on operating in California until you’re compliant.
The enforcement is real. CARB started tracking compliance in October 2024, and deadlines are being enforced as of January 1, 2025. If you miss your deadline, you’re not just risking a fine—you’re risking your ability to keep your truck on the road. Test within your 90-day window, pass before your deadline, and avoid the whole mess.
