If you’re running a 2013 or newer semi truck with a GVWR over 14,000 pounds in California, you already know the deadline isn’t optional. As of January 1st, 2024, CARB clean truck check requirements are in effect. Miss your compliance deadline and you’re looking at DMV registration holds, removal from the compliance database, and fines up to $10,000 per vehicle, per day.
That’s not a scare tactic. That’s the reality of operating heavy-duty vehicles in California right now.
The problem isn’t just the regulation itself. It’s the disruption it causes when you’re trying to run a business. Every day your truck sits waiting for testing is a day you’re not hauling freight. Every missed deadline compounds into bigger problems. And if you’re in Moreno Valley, you’re in the heart of one of the busiest logistics hubs in the country—downtime here hits harder than most places.
We bring CARB emissions testing to your location. You get certified on-site, same day when possible, with real-time reporting straight to the CARB database. If your truck passes, you’re done. If it doesn’t, we tell you exactly what needs fixing and can handle the repair and retest in one visit.
We’ve been handling CARB diesel compliance since long before the 2024 Clean Truck Check mandate created a flood of new testing providers. We’ve completed over 250 Clean Truck Checks with hands-on diesel emissions testing experience across thousands of heavy-duty vehicles. We’re credentialed by CARB, fully insured, and trusted by government agencies, utility companies, and fleet operators who can’t afford to take chances.
Moreno Valley sits at the center of the Inland Empire’s massive logistics network. You’ve got over 1,800 carriers operating in this area, serving distribution centers that support nearly 24 million people across Southern California. That means tight schedules, constant pressure, and zero tolerance for delays.
We get it because we work in it. Our mobile testing service is built for operators who need compliance handled fast, right, and without the runaround. We’re not new to this, and we’re not learning on your equipment.
First, we confirm your truck qualifies. This service applies only to 2013 or newer model year trucks with a GVWR over 14,000 pounds. If you’re running an older truck or a lighter vehicle, this isn’t the test you need.
Once we’re on-site, we connect CARB-certified OBD scanning equipment that meets SAE J1667 specifications. We’re pulling real-time data from your truck’s emission control systems—the same process CARB enforcement uses. The scan checks for fault codes, monitors system readiness, and confirms your diesel emissions are within California’s compliance thresholds.
If your truck passes, we submit the results directly to the CARB database on the spot. You get your certification immediately, and your compliance deadline is satisfied. The whole process typically takes under an hour when everything’s running clean.
If your truck doesn’t pass, we don’t leave you guessing. We’ll tell you exactly what triggered the failure—whether it’s a sensor issue, a regeneration problem, or something more involved. From there, we can handle the repair and retest in the same visit, or you can take it to your own shop. Either way, you’ll know what you’re dealing with before we leave.
Ready to get started?
You’re not just getting a smog test. You’re getting a compliance checkpoint that keeps your trucks legal and your operation moving. We bring the same equipment CARB inspectors use, so there’s no question about whether the test will hold up under scrutiny.
Every test includes OBD scanning with CARB-certified devices, real-time submission to the state compliance database, and instant certification when your vehicle passes. We also provide a full diagnostic report if something’s wrong, so you’re not left wondering what needs to be fixed or how much it’s going to cost.
In Moreno Valley, where logistics is the backbone of the local economy, timing matters. You’re operating in a region that handles a massive percentage of West Coast freight, with distribution centers running 24/7 to keep goods moving from the Ports of Long Beach and Los Angeles to the rest of the country. A compliance issue that grounds your truck for even a few days can ripple through your entire operation.
That’s why we offer same-day service and mobile testing starting at $79 per passed truck. No waiting in line at a testing center. No taking your truck out of service for half a day. We come to you, test on-site, and get you back on the road as fast as possible.
If your truck is model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds, yes—you’re required to complete a CARB clean truck check twice per year. This applies to all commercial vehicles operating in California, including semi trucks, box trucks, and other heavy-duty diesel vehicles that meet those specs.
The requirement went into effect January 1st, 2024, and compliance deadlines are tied to your vehicle registration. If you miss your deadline, the DMV will place a hold on your registration, and your truck gets flagged as non-compliant in the state database. That means you can’t legally operate it in California until you’re back in compliance.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this specific regulation doesn’t apply to you. But if you’re running newer heavy-duty equipment, this isn’t optional—it’s a legal requirement to keep your trucks on the road.
If your truck fails, we’ll tell you exactly why. The OBD scan pulls fault codes and system data that show what’s triggering the failure—whether it’s a sensor malfunction, an incomplete regeneration cycle, or an actual emissions system problem. You’ll get a diagnostic report that breaks down what needs to be addressed before your truck can pass.
From there, you have options. We can handle the repair and retest in the same visit if it’s something we can fix on-site. If it’s more involved, you can take the truck to your own shop and schedule a retest once the issue’s resolved. Either way, you’re not stuck guessing what’s wrong or paying for a test multiple times without knowing what the problem is.
The key is catching failures early. If you wait until your compliance deadline is already past, you’re dealing with penalties and registration holds on top of the repair costs. Testing up to 90 days before your deadline gives you time to fix issues without the pressure of fines piling up while your truck’s out of service.
Mobile CARB certified smog check starts at $79 per truck when your vehicle passes. That includes the OBD scan, real-time submission to the CARB database, and your compliance certification on the spot. If your truck fails and needs a retest after repairs, we’ll walk you through what that looks like based on what needs to be fixed.
There’s also a $30 annual compliance fee per vehicle that goes directly to CARB—that’s separate from the testing cost and applies to all trucks in the program. It’s not something we charge; it’s a state-mandated fee tied to your vehicle registration.
The bigger cost is what happens if you don’t test. Fines for non-compliance can hit $10,000 per vehicle, per day. If you’re running multiple trucks and miss your deadlines, those penalties add up fast. And that’s on top of the lost revenue from trucks sitting idle because they can’t legally operate. Compared to that, the cost of staying compliant is a fraction of what you’d pay if things go sideways.
Yes. We offer same-day mobile testing when you need it. If your truck’s in Moreno Valley, CA, or the surrounding Inland Empire area, we can come to your location, run the test on-site, and get your results submitted to CARB the same day—assuming your truck passes and there are no issues that need repair first.
The advantage of mobile testing is that you’re not losing half a day driving to a testing center, waiting in line, and then driving back. We bring the equipment to you, whether that’s at your yard, a distribution center, or wherever your truck’s parked. For operators in Moreno Valley, where logistics schedules are tight and every hour counts, that kind of convenience makes a real difference.
If you’re up against a compliance deadline or just want to get it handled without disrupting your operation, same-day service keeps things moving. Just keep in mind that if your truck fails and needs repairs, the timeline depends on what’s wrong and how quickly it can be fixed. But for trucks that are running clean, we can have you certified and back to work in under an hour.
For commercial vehicles, you’re required to test twice per year. That means every six months, your 2013+ truck with a GVWR over 14,000 pounds needs a passing CARB emissions test submitted to the state database. The deadlines are tied to your vehicle registration, so they’re specific to each truck in your fleet.
Agricultural vehicles and motorhomes in the same weight class only need to test once per year, but if you’re running commercial freight, you’re on the twice-a-year schedule. Missing a deadline triggers a registration hold and removes your vehicle from the compliance database, which means it can’t legally operate in California until you’re back in compliance.
The good news is that you can test up to 90 days before your deadline. That gives you a buffer to catch any issues early and get them fixed without the pressure of penalties or downtime. If you’re managing a fleet, staggering your tests throughout the year instead of waiting until the last minute can help you avoid bottlenecks and keep all your trucks running without interruption.
CARB clean truck check is specifically for heavy-duty diesel vehicles—2013 or newer trucks with a GVWR over 14,000 pounds. It’s not the same as a standard smog check for passenger cars or light-duty trucks. The equipment is different, the testing process is different, and the compliance requirements are different.
For these newer heavy-duty trucks, the test involves OBD scanning with CARB-certified devices that pull data directly from your truck’s emissions control systems. We’re checking fault codes, system readiness, and whether your diesel emissions meet California’s thresholds. The results get submitted directly to the CARB database in real time, and your compliance status updates immediately when you pass.
Regular smog checks for older or lighter vehicles use different methods—like smoke opacity tests or visual inspections—and they’re not connected to the CARB clean truck check program. If you’re running a 2013+ semi truck in California, you need the CARB-specific test. A standard smog check won’t satisfy your compliance requirement, and trying to use one will leave you out of compliance when your deadline hits.
