You’re running trucks in California. That means CARB emissions testing every six months, OBD scans for 2013 and newer diesel engines, and a compliance certificate that keeps DMV off your back and your rigs on the road.
Miss a test or fail one, and you’re looking at registration holds that ground your truck until you fix it. Fines can hit $10,000 per vehicle per day if CARB catches you out of compliance. That’s not a scare tactic—that’s what they collected $21.5 million doing in 2022 alone.
We handle Clean Truck Check testing for semi trucks and heavy-duty vehicles that fall under the new CARB diesel compliance rules. If your truck is model year 2013 or newer and weighs over 14,000 pounds GVWR, we test it with CARB-certified OBD equipment and get you the TRUCRS certificate you need to operate legally in California. You schedule the test, we run it, and you get back to work.
All SMOG Motors is a state-licensed Clean Truck Check provider serving the Hawaiian Gardens area and the wider trucking community around the I-605 and Port of Long Beach corridor. We’re CARB credentialed testers with current certification, which means we’re authorized to perform the OBD testing that 2013 and newer diesel engines require under California’s Clean Truck Check program.
Hawaiian Gardens has one of the highest concentrations of small trucking operations in the region—owner-operators, single-truck fleets, and small hauling companies that can’t afford downtime or surprise penalties. We built this service for that exact audience.
We’ve been in the industry long enough to know what happens when you miss a compliance deadline or get flagged by a roadside sensor. We also know how hard it is to find a testing facility that actually understands heavy-duty vehicle compliance and doesn’t treat your semi truck like a passenger car.
First, we confirm your truck qualifies. That means it’s a 2013 or newer diesel engine with a GVWR over 14,000 pounds. If it’s older or lighter, this isn’t the right test—and we’ll tell you that upfront.
Once you’re scheduled, we connect to your truck’s OBD system using CARB-certified testing equipment. We’re checking that your emissions control equipment is working the way it’s supposed to—DPF, SCR, EGR, all of it. The test pulls data directly from your engine’s computer. If everything checks out, you pass. If something’s flagged, we’ll tell you what needs attention before you can retest.
After a passing test, your results get uploaded to the CTC-VIS system, which is the state database CARB and DMV use to track compliance. You’ll receive your certificate of compliance, and your truck is cleared to operate in California for the next six months. That certificate is what keeps you off the enforcement list and prevents registration blocks when your renewal comes up.
The whole process takes about 30 minutes if your truck is ready and there are no issues. We also offer mobile testing if you’ve got multiple trucks or you’re based near Hawaiian Gardens and want us to come to you.
Ready to get started?
You’re paying for a CARB-certified OBD emissions test performed by a credentialed tester using state-approved equipment. That’s not something you can do yourself, and it’s not something every smog shop can handle. Heavy-duty diesel trucks fall under different rules than passenger vehicles, and the testing requirements are a lot more specific.
The compliance fee is $31.18 per vehicle. That’s the state-set rate, and it covers the test, the upload to CTC-VIS, and your certificate. We take credit cards and electronic transfers, and we’ll give you a receipt that shows your truck was tested and reported.
Hawaiian Gardens is right in the middle of a major freight zone. You’ve got the ports, the 605, the 91, and constant CARB enforcement on those routes. Roadside sensors have been scanning trucks since January 2023, and if your emissions look off, you’re getting pulled over. A valid Clean Truck Check certificate is your proof that you’re compliant and your equipment is functioning.
Starting in 2027, the testing frequency goes up to four times a year for OBD-equipped trucks. That’s not far off. Right now, it’s twice a year, and most operators we talk to are still figuring out how to stay on top of that schedule without losing work days. We help with deadline tracking and reminders if you want them—it’s part of keeping your fleet compliant without the constant stress of remembering dates.
If your truck has a 2013 or newer diesel engine and a gross vehicle weight rating over 14,000 pounds, yes. That includes semi trucks, heavy-duty pickups, box trucks, and most commercial diesel vehicles operating in California.
The Clean Truck Check program applies to nearly all diesel and alternative fuel heavy-duty vehicles over 14,000 pounds GVWR that operate on California roads. If your truck is registered in California or you’re an out-of-state operator running loads here, you’re required to test every six months and maintain a valid compliance certificate.
If your truck is older than 2013 or weighs less than 14,000 pounds, this specific test doesn’t apply. But CARB has other rules depending on your vehicle type and use, so it’s worth confirming your requirements before assuming you’re exempt.
DMV can block your registration, which means you can’t renew your plates and your truck is legally grounded. CARB can also issue citations during roadside inspections or if you’re flagged by an emissions sensor, and those fines start at $10,000 per vehicle per day.
Non-compliance isn’t just a paperwork issue. If your truck isn’t in the CTC-VIS system as current and compliant, it’s considered illegal to operate in California. That means no loads, no miles, no income until you get tested and pass.
CARB collected over $21 million in penalties in 2022, and most of that came from operators who either didn’t know about the testing requirement or kept putting it off. The enforcement is real, and it’s happening on the highways around Hawaiian Gardens every day.
About 30 minutes if your truck’s emissions system is working properly and there are no fault codes. The test itself is quick—we connect to your OBD port, pull the data, and check your emissions control equipment status.
If your truck throws a code or something’s not reading right, we’ll tell you what the issue is so you can get it fixed before retesting. Most failures are related to DPF problems, SCR malfunctions, or sensors that aren’t communicating. Those aren’t things we can clear on the spot—you’ll need a repair first.
Once you pass, we upload your results to the state system and print your certificate. You’re good to go for the next six months. If you’ve got multiple trucks, we can batch test them in one appointment or bring our mobile unit to your yard if that’s easier.
Right here. A TRUCRS certificate is what you receive after passing a Clean Truck Check emissions test, and All SMOG Motors is a licensed CTC provider in the Hawaiian Gardens area.
Not every smog shop can issue a TRUCRS certificate because not every shop is certified to test heavy-duty diesel vehicles. You need a facility with CARB-credentialed testers and the right OBD testing equipment for 2013 and newer engines. That’s what we have, and that’s what allows us to upload your passing results to the CTC-VIS system and generate your compliance certificate.
Hawaiian Gardens has a lot of small trucking companies and owner-operators, but there aren’t a ton of local testing options for heavy-duty compliance. We’re here specifically to fill that gap and make it easier for truck owners in this area to stay compliant without driving across the county.
Yes. We offer mobile Clean Truck Check testing throughout the Hawaiian Gardens area and surrounding regions. If you’ve got multiple trucks or you’re running a small fleet out of a yard near the 605 or the ports, we can bring the testing equipment to you.
Mobile testing works the same way as in-shop testing—we connect to each truck’s OBD system, run the emissions check, and upload the results to CTC-VIS on the spot. You get your certificates the same day, and your trucks stay compliant without leaving your location.
This is especially useful if you’re trying to test several vehicles at once or if your trucks are actively running loads and you can’t afford to take them out of service for half a day. We schedule around your operation, not the other way around.
A regular smog check is for passenger cars and light-duty vehicles under 14,000 pounds. CARB diesel compliance testing—also called Clean Truck Check—is specifically for heavy-duty trucks with 2013 or newer diesel engines over 14,000 pounds GVWR.
The equipment is different. The testing process is different. The reporting system is different. A standard smog shop can’t perform a Clean Truck Check unless they’re licensed and credentialed by CARB to do so, and most aren’t.
If you try to get your semi truck tested at a regular smog station, they’ll either turn you away or give you the wrong test, which won’t satisfy CARB’s requirements and won’t get you into the CTC-VIS system. You need a facility that’s set up for OBD testing on heavy-duty diesel engines—and that’s what we do.
