Hear from Our Customers
You’re hauling freight through California, and the last thing you need is a compliance issue shutting down your operation. CARB regulations aren’t suggestions—they’re enforced with registration holds and fines that compound daily.
When your truck passes CARB emissions testing here, you get the documentation California requires to keep your registration active. That means you stay on the road, meet your delivery schedules, and avoid the nightmare of explaining to clients why your rig is grounded.
The testing process is straightforward. We handle the OBD scan for your 2013 or newer diesel engine, verify your emissions systems are functioning properly, and issue your compliance certificate. You’re in and out without the bureaucratic runaround that eats up your day at other facilities.
This isn’t about checking a box. It’s about protecting your business from penalties that can reach $75,000 per day per vehicle if violations stack up. One missed test or failed inspection can trigger a chain reaction—registration blocks, contract violations, lost revenue. You already know the stakes.
We specialize in CARB compliance for the exact vehicles that face the strictest requirements—2013 and newer heavy-duty trucks over 14,000 pounds GVWR. We don’t test passenger cars or light trucks. We focus exclusively on the commercial vehicles navigating California’s toughest emissions standards.
Cherry Valley sits right in the Inland Empire trucking corridor, where freight moves between the ports and distribution centers daily. You’re dealing with tight schedules and zero tolerance for delays. We built this service around that reality.
Our technicians are CARB-certified and trained specifically on the OBD testing protocols your newer trucks require. The regulations change, testing frequency increases, and penalties get steeper. We stay current so you don’t have to become a regulatory expert on top of running your operation.
You bring your 2013 or newer heavy-duty truck to our Cherry Valley facility. We start with the OBD scan—this is the onboard diagnostics test that California requires for diesel engines in your model year range.
The scan checks your emissions control systems. We’re looking at your diesel particulate filter, NOx sensors, exhaust gas recirculation, and other components that California monitors for compliance. If everything’s functioning within CARB standards, the test moves quickly.
Once your truck passes, we issue your official compliance certificate. This is the document that keeps DMV from placing a registration hold on your vehicle. You’ll need to maintain this certification on the schedule CARB sets—currently semi-annually for most trucks in your category, though that frequency increases to quarterly by 2027.
If something flags during the scan, we’ll tell you exactly what triggered it and what needs attention before you can pass. No guessing. No vague explanations. You get clear information about what’s wrong and what it takes to fix it.
The whole process typically takes under an hour if your truck’s systems are operating correctly. You’re not sitting around all day waiting for results.

This service applies only to trucks that are model year 2013 or newer and have a GVWR over 14,000 pounds. If your truck doesn’t meet both criteria, this isn’t the test you need.
You get a full OBD emissions scan performed by CARB-certified technicians using state-approved equipment. The test evaluates your diesel emissions systems against California’s Clean Truck Check standards. When you pass, you receive the compliance certificate that satisfies California’s registration requirements.
Cherry Valley’s location in Riverside County puts you in one of California’s busiest freight zones. Trucks moving through here are subject to the same CARB standards whether you’re California-registered or running interstate commerce through the state. The regulations don’t care where your plates are from—if you operate in California, you comply or you pay.
The testing frequency depends on your truck’s specifics, but most 2013+ trucks in this weight class currently test twice per year. That schedule is increasing. By October 2027, you’ll be testing four times annually. The compliance burden is going up, not down.
Each test costs significantly less than a single day of fines. CARB penalties start at $10,000 per vehicle per day for non-compliance. A registration hold can ground your truck until you resolve the issue, which means lost contracts and revenue on top of the fines.
Right now, most trucks with 2013 or newer engines over 14,000 pounds GVWR need testing twice per year—that’s semi-annually. The exact schedule can vary slightly based on your truck’s specific configuration and GVWR, but semi-annual is standard for this category.
That frequency is changing. California is phasing in more frequent testing requirements. By October 2027, your truck will need testing four times per year—quarterly. The state is tightening compliance timelines across the board.
You can’t skip a test or push it back. Miss your testing window and DMV can place a registration hold on your vehicle. That hold prevents you from legally operating in California until you complete the required testing and clear the block. The penalties for operating without current compliance can hit $10,000 per vehicle per day, and they compound quickly if you’re caught during an inspection or roadside check.
If your truck fails, you won’t receive the compliance certificate you need for registration. We’ll give you a detailed report showing exactly what triggered the failure—usually it’s a specific emissions system component that’s malfunctioning or reading outside CARB’s acceptable parameters.
Common failure points include diesel particulate filter issues, NOx sensor malfunctions, or problems with the exhaust gas recirculation system. These are the components California monitors most closely on 2013+ diesel engines. The OBD scan catches these problems immediately.
You’ll need to get the flagged issue repaired before you can retest and pass. Once repairs are complete, bring the truck back for another scan. If the problem’s fixed and everything reads within standards, you’ll pass and get your certificate. There’s no penalty for failing the test itself—the penalty comes if you keep operating without valid compliance certification.
Yes, if you operate in California with any regularity. CARB regulations apply to all heavy-duty trucks operating within California’s borders, regardless of where the vehicle is registered. Your plates don’t matter—your operation does.
If you’re running freight into California, delivering to distribution centers, or traveling through the state as part of your regular routes, you need CARB compliance. California doesn’t exempt interstate carriers from emissions standards. The state handles nearly 40% of U.S. imports, and they enforce these rules on every truck moving through their freight corridors.
The enforcement is real. California conducts roadside inspections and facility checks. If you’re caught operating without current CARB compliance, you face the same penalties as California-registered trucks—up to $10,000 per vehicle per day. Registration holds can also prevent you from operating legally until you resolve the compliance issue. Don’t assume you’re exempt because your truck’s registered elsewhere. If you work in California, you comply with California rules.
Testing costs a fraction of what you’ll pay in fines if you skip it. CARB facilities typically charge up to $300 per test. That’s your cost to stay legal and operational.
Compare that to the penalties. Non-compliance fines start at $10,000 per vehicle per day. If you’re running multiple trucks or violations stack up over several days, you’re looking at exposure that can reach $75,000 per day per vehicle. These aren’t theoretical maximums—California actively enforces these penalties.
Beyond the fines, there’s the operational cost. A registration hold grounds your truck. You can’t legally operate until you complete testing and clear the block. That means missed deliveries, broken contracts, and lost revenue while your truck sits idle. The testing fee is cheap insurance against business disruption that costs exponentially more. You’re not paying for a piece of paper—you’re paying to keep your operation running without interruption.
California introduced stricter emissions standards for diesel engines starting with 2010 model years, but the 2013+ trucks have more advanced onboard diagnostics systems that CARB can monitor electronically. Your truck’s OBD system tracks emissions components in real-time, which is exactly what the compliance test scans.
The OBD testing for 2013 and newer engines is more comprehensive than older testing methods. California can verify that your diesel particulate filter, NOx sensors, and other emissions controls are functioning correctly—not just at the moment of testing, but continuously during operation. That’s why these trucks face more frequent testing requirements.
Older trucks and lighter vehicles have different testing protocols or may be exempt from certain requirements. But if you’re running a 2013 or newer heavy-duty diesel over 14,000 pounds GVWR, you’re in the highest scrutiny category. California is pushing the hardest on this segment because these trucks represent the largest portion of commercial freight emissions. The testing burden on your truck is only increasing as the state tightens standards.
Yes, if your truck passes the emissions test. The OBD scan itself doesn’t take long—usually under an hour for a straightforward test when your systems are functioning properly. Once the scan confirms everything’s within CARB standards, we issue your compliance certificate immediately.
You walk out with the documentation you need to maintain your California registration and avoid compliance issues. There’s no waiting period for results or certificate processing. The test is electronic, the results are instant, and the certificate gets issued on the spot when you pass.
If your truck fails, you won’t get the certificate until you complete repairs and pass a retest. But assuming your emissions systems are working correctly and you’re current on maintenance, same-day certification is standard. We’re not here to create delays—we’re here to get you tested, certified, and back on the road as quickly as possible.
