You’re not worrying about a $1,000-per-day fine showing up because one of your trucks got flagged at a weigh station. Your DMV registrations go through without blocks. Your drivers aren’t sitting on the side of the road waiting for you to sort out compliance paperwork.
Your fleet operates the way it’s supposed to—on schedule, legally, without the constant background stress of whether CARB or CHP is going to pull you over. You’ve got proof of compliance in the Clean Truck Check database, and your semi-annual testing gets handled before the deadlines hit.
That’s what compliance actually gets you. Not a certificate to frame. Just fewer problems and more uptime for the trucks that make you money.
We handle CARB emissions testing for the trucks that actually need it—model year 2013 or newer with a GVWR over 14,000 pounds. That’s it. We’re not trying to be everything to everyone.
We’re in Redondo Beach, CA, which puts us right in the middle of one of the busiest commercial corridors in the state. Drayage trucks moving containers from the ports. Interstate haulers coming through. Construction fleets working job sites across the South Bay. If your trucks operate in California, they need compliance testing—and we know exactly what that looks like for heavy-duty diesel equipment.
We use CARB-certified OBD testing devices, we understand the Clean Truck Check database requirements, and we know the deadlines. You’re not explaining your situation to someone who usually does passenger cars.
First, we verify your truck qualifies—2013 or newer, over 14,000 pounds GVWR. If it doesn’t meet both criteria, we’ll tell you upfront. No point wasting your time.
Once we confirm eligibility, we run the OBD emissions test using CARB-certified equipment. For 2013 and newer diesel engines, this connects directly to your truck’s onboard diagnostics to check that emissions control systems are functioning properly. The test itself doesn’t take all day—we’re not doing manual inspections that tie up your equipment for hours.
After the test, if your truck passes, that result gets submitted to the Clean Truck Check database. You’ll have proof of compliance that satisfies CARB requirements and keeps your DMV registration clear. If there’s an issue, we’ll tell you exactly what needs attention before you can pass.
You can submit passing tests up to 90 days before your compliance deadline, which gives you flexibility to plan around your operating schedule instead of scrambling at the last minute. Starting in 2025, most trucks need testing twice a year—every six months. We’ll keep track of your testing schedule so you’re not trying to remember when the next deadline hits.
Ready to get started?
You get OBD emissions testing performed with CARB-certified equipment on your 2013 or newer heavy-duty truck. That’s the core service. We test whether your emissions control systems are working the way California requires them to work.
If your truck passes, we handle the submission to CARB’s Clean Truck Check database. That’s the system California uses to track compliance for heavy-duty vehicles operating in the state. Your passing test gets recorded, which is what keeps CARB and CHP off your back and prevents DMV registration issues.
We also help with the administrative side—making sure you’re registered in the database and that your $30 annual compliance fee per vehicle is sorted. It’s not complicated, but it’s one more thing you don’t need to figure out yourself.
Here’s what matters for Redondo Beach, CA operators specifically: you’re close to the ports, which means higher scrutiny. CARB has roadside monitoring stations, and they send letters to fleet operators about non-compliant vehicles they’ve spotted. The closer you are to major freight corridors, the more likely you are to get flagged if you’re not compliant. We’re local, we understand that pressure, and we make sure your trucks have the documentation they need before they hit those routes.
If your truck is model year 2013 or newer and has a GVWR over 14,000 pounds, and it operates anywhere in California, compliance testing isn’t optional. As of January 1, 2024, all qualifying trucks need proof of compliance to operate legally in the state.
This applies whether you’re California-registered or out-of-state. If your truck crosses into California, CARB regulations apply to you. Operating without compliance registration can result in violations from CARB or CHP, fines up to $1,000 per day per vehicle, and blocks on your DMV registration.
The testing requirement is semi-annual starting in 2025—meaning twice per year, every six months. You can submit passing tests up to 90 days before your deadline, but you can’t skip it. This isn’t a “maybe” situation. It’s a legal requirement to operate heavy-duty trucks in California.
Fines can hit $1,000 per day per vehicle. That’s not a one-time penalty—it’s daily, and it adds up fast if you’ve got multiple trucks running non-compliant.
Beyond the fines, you’re looking at DMV registration blocks. Your trucks won’t be able to renew registration in California, which means they can’t legally operate. If CARB or CHP catches a non-compliant truck during a roadside check or at a weigh station, that vehicle gets pulled off the road until you sort out compliance.
Then there’s downtime. Every day a truck sits waiting for compliance testing or dealing with enforcement action costs you $300 to $900 in lost revenue, depending on what that truck would normally be hauling. For fleet operators, multiply that across multiple vehicles and you’re looking at serious money lost—not because of mechanical issues, but because of paperwork you didn’t handle.
OBD testing for 2013 and newer diesel trucks doesn’t take hours. We’re not doing the kind of manual inspections that tie up your equipment for half a day. The actual test connects to your truck’s onboard diagnostics and checks emissions control system function.
Most trucks are in and out without the kind of downtime that kills your schedule. We’re not running a shop that makes you drop off your truck for the day and hope it’s ready by closing time.
The bigger time consideration is planning ahead. You can submit passing tests up to 90 days before your compliance deadline, so you’re not scrambling at the last minute when your deadline hits and suddenly every testing facility is backed up. If you wait until the week before your deadline, you’re gambling with your operating schedule. If you plan ahead, testing fits into your routine without disrupting your hauls.
TRUCRS stands for Truck Regulation Upload Compliance Reporting System. It’s part of how CARB tracks compliance for certain heavy-duty truck regulations, but it’s separate from Clean Truck Check, which is what handles the emissions testing compliance we’re talking about here.
For the 2013 or newer trucks over 14,000 pounds GVWR that need semi-annual emissions testing, you’re dealing with the Clean Truck Check database. That’s where your passing test results get submitted and where CARB verifies you’re compliant.
TRUCRS is more relevant if you’re dealing with other CARB regulations like the Truck and Bus rule or reporting requirements for older equipment. The systems overlap in some areas, but for the emissions testing compliance that keeps your 2013+ trucks legal, Clean Truck Check is what matters. We handle the submission to that database when your truck passes testing, so you’ve got the proof of compliance CARB requires.
Yes. If your truck operates in California, CARB regulations apply regardless of where it’s registered. It doesn’t matter if you’re plated in Nevada, Arizona, Texas, or anywhere else. The moment your 2013 or newer heavy-duty truck crosses into California, you’re subject to the same compliance requirements as California-registered vehicles.
CARB doesn’t give exemptions for out-of-state operators. They’ve made that clear. If you’re hauling freight to or through California—whether it’s a one-time delivery or regular routes—your qualifying trucks need to be registered in the Clean Truck Check database and have current passing emissions tests on file.
Interstate operators get caught off guard by this all the time. They assume California rules only apply to California trucks. That’s not how it works. CHP and CARB enforcement applies to any heavy-duty vehicle on California roads, and they check compliance at weigh stations and roadside monitoring points. If you’re not compliant, your truck gets flagged, and you’re dealing with the same penalties as everyone else—fines, potential impoundment, and downtime while you sort it out. Get compliant before you cross the state line, not after you get pulled over.
If your truck fails, we’ll tell you exactly what triggered the failure. OBD testing checks your emissions control systems—things like your diesel particulate filter, NOx sensors, and other components that manage exhaust output. A failure means something in that system isn’t functioning within CARB’s parameters.
You’ll need to get the issue repaired before your truck can pass a retest. We’re not a repair shop, so you’ll need to take it to a facility that handles heavy-duty diesel emissions systems. Once repairs are done, you come back for another test.
Here’s the important part: you can’t submit a passing test until your truck actually passes. That means if your deadline is coming up and your truck fails, you’re on the clock to get repairs done and get retested before that deadline hits. This is why testing early—up to 90 days before your deadline—matters. If you wait until the last minute and your truck fails, you’re in a bind. You’re either rushing repairs and hoping for a quick turnaround, or you’re missing your deadline and facing penalties while your truck sits non-compliant.
