Hear from Our Customers
You’re running a business, not studying California emissions regulations. But here’s what matters: if your 2013 or newer diesel truck isn’t compliant, the DMV blocks your registration. No registration means no operation. No operation means no income.
CARB’s Heavy-Duty Inspection and Maintenance program isn’t optional anymore. Every truck over 14,000 pounds GVWR with an OBD system needs testing twice a year. Miss a deadline or fail a test, and you’re looking at fines up to $10,000 per vehicle per day. That’s not a scare tactic—that’s the actual penalty structure.
We handle clean truck check testing for the Jurupa Valley area because we know what’s at stake. You get tested by a CARB-certified technician using approved OBD scanners. Your results get submitted directly into the state’s CTC-VIS system. You get your certificate, your truck stays on the road, and your business keeps moving.
We specialize in CARB compliance for newer heavy-duty trucks in Jurupa Valley and surrounding areas. We’re not a general smog shop trying to figure out diesel emissions on the fly. We focus specifically on 2013+ trucks with OBD systems because that’s what the state requires testing for—and that’s what you’re driving.
Jurupa Valley sits right in the middle of major logistics corridors. You’ve got trucks moving between the Inland Empire, LA, and Ontario daily. That means CARB enforcement is tight, and compliance isn’t something you can put off. We’ve worked with independent owner-operators, construction fleets, and delivery companies who all face the same problem: they need testing done correctly, quickly, and without surprises.
Our testers are CARB-credentialed through the official Training and Authorization System. That means your test results are valid, your certificate is recognized statewide, and you’re not dealing with rejected submissions or retests because someone cut corners.
First, we verify your truck qualifies. That means checking the model year, GVWR, and confirming it has an OBD system. If your truck is 2012 or older, or under 14,000 pounds, this program doesn’t apply to you yet.
Once we confirm eligibility, we connect to your truck’s OBD port using a CARB-approved scanner. The system pulls diagnostic data directly from your engine’s computer—checking for fault codes, emissions performance, and system readiness. This isn’t a tailpipe test. It’s a data-driven inspection that reads what your truck is already monitoring.
If everything checks out, we submit your passing results directly to the state’s CTC-VIS database. You receive your clean truck check certificate, which satisfies your compliance requirement for the next six months. If there’s an issue, we’ll tell you exactly what failed and what needs repair before retesting. No guessing, no runaround.
The whole process takes about 30 minutes if your truck is ready. You can submit passing results up to 90 days before your deadline, so there’s no reason to wait until the last minute and risk a registration block.
Ready to get started?
You’re getting an official CARB compliance test performed by a credentialed technician. That’s not the same as a standard smog check. This is OBD emissions testing specific to heavy-duty diesel trucks, and it requires different equipment, different training, and different certification.
Your test results get uploaded to the state’s system in real time. That means the DMV sees your compliance status immediately—no waiting for paperwork to process or wondering if your test was recorded. You also get a certificate you can show during roadside inspections or when entering ports and railyards, which now deny access to non-compliant trucks.
In Jurupa Valley, you’re close to major freight hubs and inspection points. CHP and CARB enforcement teams are active on the 60, 91, and 15 freeways. If you get pulled over and can’t show proof of compliance, you’re facing citations and potential impoundment. Having current documentation isn’t just smart—it’s required.
We also help with CTC-VIS registration if you’re new to the program. That’s the online system where you pay your annual compliance fee and track your testing history. It’s confusing the first time, and most truck owners don’t want to spend an hour navigating a state website. We walk you through it or handle it directly so you’re set up correctly from the start.
Right now, trucks with OBD systems need testing twice a year. That’s every six months, and you need to pass both tests to stay compliant. Your deadline is based on your vehicle’s registration month, and the state sends reminders through the CTC-VIS system.
Starting in October 2027, testing frequency increases to four times per year for OBD-equipped vehicles. That’s every three months. The state is phasing this in to tighten emissions monitoring, so if you’re planning to keep your truck past 2027, factor that into your maintenance schedule.
You can submit a passing test up to 90 days early, which gives you flexibility if you’re planning to be out of state or expect heavy workloads. Just don’t wait until the deadline—if you fail and need repairs, you’ll run out of time and risk a registration block.
If your truck fails, you’ll get a detailed report showing exactly which OBD codes or systems triggered the failure. Most failures are related to emissions control components—things like the diesel particulate filter, EGR system, or NOx sensors. These are repairable issues, not total losses.
You’ll need to get the repairs done by a qualified diesel mechanic, then return for a retest. There’s no penalty for failing the test itself—the penalty comes if you don’t retest and pass before your compliance deadline. That’s when the DMV blocks your registration and fines start piling up.
Some owners try to clear codes and hope the system resets before testing. That doesn’t work. The OBD system tracks “readiness monitors,” which show whether the truck has run enough cycles after a repair for the computer to verify everything’s working. If those monitors aren’t set, the test is incomplete, and you won’t pass. There’s no shortcut here.
Yes. If your truck operates in California—even if it’s registered in another state—you need CARB compliance testing. The program applies to any heavy-duty truck over 14,000 pounds GVWR that drives on California roads, regardless of where it’s plated.
Out-of-state trucks follow the same testing schedule as California-registered vehicles. You’ll need to register in the CTC-VIS system, pay the annual compliance fee, and submit passing test results twice a year. If you’re caught operating in California without compliance, you face the same fines and penalties as in-state operators.
This catches a lot of long-haul drivers off guard, especially if they’re just passing through. But California’s enforcement is strict, and ignorance isn’t a defense. If you’re running regular routes into the state, get compliant now. It’s cheaper and easier than dealing with a roadside citation or getting turned away at a port.
Yes. Mobile testing brings the equipment to your location, which saves you time and keeps your trucks operating instead of sitting at a shop. This works well for fleets or owner-operators who can’t afford downtime or don’t want to drive across town for a 30-minute test.
Mobile testing uses the same CARB-approved OBD scanners and follows the same procedures as in-shop testing. The results are just as valid, and they’re submitted to the state’s system the same way. The only difference is convenience—we come to you.
For Jurupa Valley, mobile testing makes sense if you’re running multiple trucks or operating out of a yard. You can schedule all your trucks on the same day, keep them on-site, and get everyone compliant without disrupting your schedule. It’s not free, but the cost is usually less than the revenue you’d lose from pulling trucks off jobs.
Regular smog checks are for passenger vehicles and light-duty trucks under 14,000 pounds. They measure tailpipe emissions using a probe and a dynamometer in some cases. CARB compliance testing is for heavy-duty trucks over 14,000 pounds, and it’s entirely OBD-based. No tailpipe probe, no dyno—just a direct connection to your truck’s computer.
The equipment is different, the certification is different, and the reporting system is different. A standard smog shop can’t perform CARB compliance testing unless they have a technician who’s been credentialed through the CARB Training and Authorization System and they have the approved OBD scanners. Most don’t.
That’s why you can’t just take your semi to the same place you take your pickup. The test doesn’t exist there. You need a facility or technician specifically set up for heavy-duty emissions testing, and in Jurupa Valley, that’s not every shop. Make sure whoever you’re working with is actually certified before you waste time and money.
Testing costs vary depending on whether you’re coming to a shop or using mobile service, but expect to pay between $150 and $300 per truck for the test itself. That doesn’t include the annual CTC-VIS compliance fee, which is separate and paid directly to the state.
If your truck fails and needs repairs, that’s additional. Diesel emissions repairs can range from a few hundred dollars for a sensor replacement to several thousand for a DPF or SCR system overhaul. The test just identifies the problem—it doesn’t fix it.
Some shops in the area charge less, but make sure they’re actually certified. A cheap test that doesn’t get accepted by the state costs you more in the long run because you’ll have to retest somewhere else. You’re better off paying a fair price to a credentialed tester and getting it done right the first time than chasing bargains and ending up with rejected results.
