If you’re running heavy-duty diesel trucks in California, you already know the stakes. Miss your Clean Truck Check deadline, and you’re looking at DMV registration holds that ground your fleet. Fail to submit passing emissions tests, and CARB can hit you with fines up to $10,000 per vehicle, per day.
That’s not a scare tactic. That’s the reality as of January 2025.
Your trucks need to pass CARB emissions testing if they’re model year 2013 or newer and weigh over 14,000 pounds GVWR. No exceptions. The state uses roadside monitoring to flag high emitters, and if your truck gets flagged, you’ve got 30 days to submit a passing test or face consequences.
We handle the OBD testing, submit results directly to CARB, and get you the certificate you need to keep your registration current. You avoid the fines, the downtime, and the headache of trying to figure this out on your own. That’s what CARB compliance should look like—handled, not hanging over your head.
We aren’t trying to be everything to everyone. We specialize in Clean Truck Check inspections for 2013 and newer heavy-duty trucks in El Segundo, CA—that’s it.
El Segundo sits in the heart of Southern California’s logistics corridor. Performance Team, California’s largest logistics company, operates right here on East Maple Avenue. You’ve got fleets running through Carson, Torrance, Long Beach, and LAX daily. The trucking density here means CARB enforcement is constant, and compliance isn’t optional.
We’re CARB credentialed testers using certified OBD devices. We know the regulations, the deadlines, and what it takes to get your results submitted without delays. You’re not calling a general smog shop hoping they understand heavy-duty diesel—you’re working with people who only do this.
First, we confirm your truck qualifies. This service applies only to model year 2013 or newer diesel trucks with a GVWR over 14,000 pounds. If your truck is older or lighter, this isn’t the program you need.
Once confirmed, we schedule your OBD emissions test. We can come to your location in El Segundo or you can bring the truck to us—whatever works for your operation. The test itself is quick. We’re plugging into your truck’s onboard diagnostics system, not running a full manual inspection. Most OBD tests take far less time than the old 1-3 hour manual inspections.
After testing, we submit your results electronically to CARB within 72 hours. If you pass, CARB updates your compliance status and we provide your certificate. The DMV gets updated within seven days, and your registration stays clear.
If your truck doesn’t pass, you’ve got time to make repairs. You can submit passing tests up to 90 days before your deadline, so there’s room to address issues without panic. We’ll walk you through what failed and what needs fixing.
Ready to get started?
You get a full OBD emissions test using CARB-certified equipment. We’re checking your diesel truck’s emissions systems through the onboard diagnostics—no guesswork, no shortcuts.
Results go straight to CARB electronically. You’re not responsible for mailing forms or tracking down confirmation. We handle the submission, and you get a certificate showing your truck passed and is compliant.
El Segundo fleets deal with tight schedules. You’re moving freight through the ports, serving LAX cargo operations, or running regional hauls through some of the busiest corridors in California. Downtime costs you $300 to $900 per vehicle depending on your operation. Our mobile service means we come to you, test on-site, and get you back to work.
The annual compliance fee is $31.18 per vehicle in 2025—that’s separate from our testing service, and it’s paid directly to CARB. What you’re paying us for is the test, the expertise, and the direct submission that keeps your trucks legal.
This isn’t a one-and-done situation either. Heavy-duty diesel compliance is ongoing. Miss a deadline, and you’re facing registration holds that stop your trucks cold. We help you stay ahead of those deadlines so your fleet keeps moving.
Your truck needs this test if it’s model year 2013 or newer, runs on diesel or alternative fuel, and has a gross vehicle weight rating over 14,000 pounds. It doesn’t matter where your truck is registered—if you’re operating on California public roads, you’re subject to CARB compliance.
This applies to nearly all heavy-duty diesel trucks in commercial fleets. Semis, box trucks, heavy haul rigs, specialized freight vehicles—if they meet those criteria, they need testing.
Older trucks and lighter vehicles follow different rules. If your truck is pre-2013 or under 14,000 pounds GVWR, this specific Clean Truck Check program doesn’t apply to you. But if you’re running newer heavy-duty equipment in El Segundo or anywhere in California, this is mandatory.
CARB can fine you up to $10,000 per vehicle, per day for non-compliance. That’s not a maximum they rarely use—that’s the penalty structure, and they enforce it.
On top of fines, the DMV will place a registration hold on any truck that’s out of compliance. That means you can’t renew registration, and you can’t legally operate that vehicle on California roads until you submit a passing test and get cleared.
Downtime is the other cost. If your truck is sitting because of a registration hold, you’re losing $300 to $900 per day depending on your operation. Add that up over a week or two while you scramble to get compliant, and you’re looking at thousands in lost revenue on top of the fines. The cost of staying compliant is a fraction of what non-compliance will run you.
We connect a CARB-certified OBD device to your truck’s diagnostic port. The system reads data from your truck’s emissions controls—things like the diesel particulate filter, NOx sensors, and exhaust systems.
The test checks whether your truck’s emissions equipment is working properly and within California’s limits. It’s not a visual inspection or a manual smoke test for 2013 and newer trucks—it’s all electronic data pulled directly from your vehicle’s computer.
If everything checks out, you pass, and we submit the results to CARB electronically. You get a certificate, and your compliance status updates within 72 hours. If something’s flagged, we’ll tell you exactly what failed so you can get it repaired and retested before your deadline.
Yes. CARB allows you to submit passing test results up to 90 days before your compliance deadline. That’s actually the smart move.
Testing early gives you a buffer. If your truck doesn’t pass, you’ve got time to make repairs and retest without the pressure of an approaching deadline. If you wait until the last minute and fail, you’re racing the clock to avoid registration holds and fines.
Most fleets in El Segundo that stay on top of compliance test well in advance. It’s easier to schedule, there’s no panic if something needs fixing, and you’re never operating with expired compliance status. We recommend reaching out at least 60-90 days before your deadline to get on the schedule.
Yes. We bring the equipment to your location anywhere in El Segundo. If you’ve got multiple trucks, we can test them on-site without pulling your fleet off the road one by one.
Mobile testing makes sense for busy operations. You’re not losing half a day driving trucks to a shop, waiting in line, and driving back. We come to you, test on-site, and you keep your schedule intact.
El Segundo fleets are running tight operations—freight moves fast here, and downtime is expensive. Mobile service cuts that downtime to almost nothing. We schedule around your availability, show up with certified equipment, run the tests, and submit results directly to CARB. You stay compliant without disrupting your operation.
We submit your test results to CARB electronically within 72 hours of testing. Once submitted, CARB updates your compliance status in their system, and you receive a certificate showing you passed.
The DMV takes about seven days to update their records after CARB processes your results. That means if you’re renewing registration, allow at least a week between testing and when you need the compliance reflected in DMV systems.
If you’re cutting it close to a deadline, that timing matters. Test early enough that the DMV update happens before your registration expires. If you wait until the last day and pass your test, there’s still a processing window before everything clears. We’ll walk you through timing when you schedule so you’re never caught waiting on paperwork.
