California doesn’t mess around with diesel compliance. If your truck is model year 2013 or newer and weighs over 14,000 pounds GVWR, you’re required to complete a Clean Truck Check to keep your registration active and your operation legal.
Miss your deadline and the DMV puts a hold on your registration. Keep operating without compliance and you’re looking at fines that can hit $10,000 per vehicle per day. That’s not a scare tactic—that’s state law.
We handle CARB emissions testing for heavy-duty trucks right here in Eastvale. You get a CARB-certified inspection using the equipment and protocols the state requires. The test itself takes about 15 minutes, and if you pass, you get your compliance certificate digitally so you can move forward without the stress of wondering if you’re covered.
This isn’t about upselling you or dragging out the process. It’s about getting your truck tested correctly so you stay compliant and keep rolling.
All SMOG Motors is a CARB-credentialed testing facility serving Eastvale and the surrounding Inland Empire. We’re certified to perform Clean Truck Checks on 2013 and newer heavy-duty diesel trucks, and we’ve been doing this long enough to know what fleet operators and owner-operators actually need: speed, accuracy, and no runaround.
Eastvale sits right in the middle of one of the busiest logistics corridors in Southern California. You’ve got I-15 and SR-60 nearby, which means trucks are constantly moving through here. We built this service to meet that demand without wasting your time.
Our testers are CARB-certified with the training and equipment required to perform OBD inspections that meet SAE J1667 standards. We carry the liability insurance and business credentials the state requires, and we submit results directly into the CARB system so your compliance is documented the right way.
When you bring your truck in, we start by confirming it qualifies for the Clean Truck Check program. That means it’s model year 2013 or newer and has a GVWR over 14,000 pounds. If it doesn’t meet those criteria, this test doesn’t apply to you.
Once we verify eligibility, we connect to your truck’s onboard diagnostics system using CARB-approved equipment. The OBD scan pulls emissions data directly from your engine control module. We’re checking for fault codes, readiness monitors, and whether your emissions system is functioning the way California says it should.
The scan itself takes less than five minutes in most cases. If everything checks out, we submit your passing results to CARB electronically and issue your compliance certificate right away. You can submit a passing test up to 90 days before your compliance deadline, which gives you a buffer if repairs are needed.
If your truck doesn’t pass, we’ll walk you through what triggered the failure and what needs to be addressed. You’ll need to get the issue fixed and come back for a retest, but at least you’ll know exactly what’s wrong before your deadline hits.

This service applies only to trucks that are model year 2013 or newer and have a gross vehicle weight rating over 14,000 pounds. If your truck is older or lighter, you don’t need a Clean Truck Check—you may need a different type of smog test, but not this one.
When you come in, you’re getting a CARB HD I/M test performed by a credentialed tester using certified diagnostic equipment. We’re not just plugging in a scanner and calling it good. The equipment has to meet specific technical standards, and the tester has to be trained and certified by the state. That’s what keeps the test valid and your compliance legitimate.
Eastvale’s location makes it a natural hub for trucking and logistics. With nearly 300 carriers operating within 50 miles, there’s a lot of heavy-duty equipment moving through this area. That also means there’s a lot of scrutiny from CARB and local enforcement. If you’re running trucks in California, this isn’t optional—it’s part of doing business here.
You’ll also need to pay the annual compliance fee of $31.18 for 2025, which is separate from the testing fee. That goes directly to CARB, not to us. We handle the test, submit the results, and get you the certificate. You handle the fee payment through the state system.
Your truck needs a Clean Truck Check if it meets two criteria: it’s model year 2013 or newer, and it has a gross vehicle weight rating over 14,000 pounds. This applies to heavy-duty diesel trucks, including semi-trucks, box trucks, and some larger commercial vehicles.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this program doesn’t apply to you. You might still need a different type of emissions test depending on your vehicle, but not a Clean Truck Check specifically.
The program also applies to out-of-state trucks operating in California. If you’re bringing a qualifying truck into the state for work, you’ll need to comply with the same testing requirements as California-registered vehicles. CARB enforces this at the state level, so even if your truck is registered elsewhere, you’re still on the hook if you’re operating here.
If you miss your compliance deadline, the DMV will place a registration hold on your vehicle. That means you can’t renew your registration until you complete the test and submit passing results to CARB. You also can’t legally operate the truck on California roads while it’s out of compliance.
Beyond the registration hold, you’re looking at potential fines. California can issue penalties up to $10,000 per vehicle per day for operating a non-compliant truck. If CARB or local enforcement catches you on the road without a valid compliance certificate, those fines add up fast.
You can submit a passing test up to 90 days before your deadline, which gives you time to address any issues if your truck doesn’t pass on the first try. That buffer is there for a reason—use it. Waiting until the last minute leaves you no room for repairs or retesting if something goes wrong.
The actual OBD scan takes less than five minutes in most cases. We connect to your truck’s diagnostic system, pull the emissions data, and check for fault codes or readiness issues. If everything looks good, the test is done and we submit your results electronically.
The whole appointment usually takes about 15 minutes from start to finish, including paperwork and certificate issuance. That’s assuming your truck passes and there are no complications. If we find an issue, we’ll walk you through what needs to be fixed, but the diagnostic part itself is quick.
You don’t need to leave your truck with us or schedule a long service window. This is a plug-in test, not a full inspection. Bring your truck in, we run the scan, and you’re back on the road. If you’re managing a fleet, that turnaround time matters—you’re not losing half a day per truck just to stay compliant.
If your truck doesn’t pass, we’ll give you a detailed report of what triggered the failure. Usually it’s a fault code related to your emissions system—something like a DPF issue, an EGR valve problem, or a sensor malfunction. The OBD system will flag exactly what’s wrong, so you’re not guessing.
You’ll need to get the issue repaired before you can retest. We don’t do the repairs ourselves, but we can point you toward what needs to be fixed based on the diagnostic codes. Once the repair is done, bring the truck back and we’ll run the test again.
The good news is you can test up to 90 days before your deadline. That window exists specifically so you have time to handle repairs without scrambling at the last minute. If you wait until a week before your deadline and fail, you’re in a tough spot. Test early, and you’ve got breathing room to fix whatever comes up.
Yes, if your truck meets the criteria—2013 or newer, over 14,000 pounds GVWR—and you’re operating it in California, you need to comply with the Clean Truck Check program. It doesn’t matter where your truck is registered. CARB enforces this rule at the state level for any qualifying vehicle operating on California roads.
Out-of-state operators sometimes assume they’re exempt, but that’s not how it works. California has its own emissions standards, and if you’re doing business here, you’re subject to those standards. The EPA partially disapproved some aspects of California’s rule for out-of-state trucks, but the state continues to enforce compliance through its own authority.
If you’re running regular routes into California, factor this into your operating costs and schedule. You’ll need to test on the same timeline as California-registered trucks, and you’ll need to keep your compliance certificate current. Enforcement can happen at weigh stations, during roadside inspections, or through CARB audits, so it’s not worth the risk of skipping it.
Testing costs typically range from $50 to $150 depending on the facility and any additional services included. At All SMOG Motors, we keep the process straightforward—you’re paying for the CARB-certified OBD test, the submission of results, and your compliance certificate.
You’ll also need to pay the annual compliance fee to CARB, which is $31.18 for 2025. That fee is separate from the testing cost and goes directly to the state, not to us. It’s part of the program requirement, and you’ll need to pay it regardless of where you get tested.
The cost of non-compliance is a lot higher. Registration holds mean downtime, and fines can reach $10,000 per vehicle per day if you’re caught operating without a valid certificate. When you factor in lost revenue from a truck sitting idle, the testing fee is a small price to pay to stay legal and keep your operation moving.
