You’ve got trucks to run and deadlines to meet. The last thing you need is a compliance issue shutting down your operation or costing you thousands in penalties.
California’s Clean Truck Check program requires emissions testing twice a year for heavy-duty diesel trucks—and if you’re running 2013 or newer models over 14,000 pounds GVWR, you’re required to use CARB certified OBD testing. Miss a deadline and you’re looking at registration holds, fines up to $10,000 per vehicle per day, and trucks sitting idle when they should be working.
We handle the testing so you can focus on the job. Mobile service means we come to your yard or job site in Valle Vista. You’re in and out in 15 minutes with your CTC certificate in hand. No guessing if you’re compliant. No scrambling when DMV flags your registration. Just clean records and trucks that are legal to operate on California roads.
We’re CARB credentialed and licensed by the state of California to perform Clean Truck Check emissions testing. We’re also insured—something most mobile testers can’t say.
We’ve been serving Valle Vista and the surrounding Riverside County area with reliable CARB emissions testing for fleets, owner-operators, and commercial truck operators who need compliance done right. Our technicians are trained, certified, and experienced with the OBD testing requirements that apply to 2013 and newer diesel engines.
We work with utility companies, government agencies, and private fleets who need TSA-cleared access to airports and port terminals. If your operation depends on staying compliant, you need a testing provider you can count on—not someone who shows up late or cuts corners.
First, we confirm your truck qualifies. This service is only for diesel trucks that are model year 2013 or newer and have a gross vehicle weight rating over 14,000 pounds. If your truck is older or lighter, this isn’t the right test.
Once we’re on-site in Valle Vista, we connect our CARB certified OBD device to your truck’s diagnostic system. The test pulls emissions data directly from your engine’s onboard computer. It’s non-invasive, quick, and doesn’t require a visual inspection or tailpipe test like older smog checks.
If your truck passes, we issue your Clean Truck Check certificate on the spot and report the results to the CTC-VIS system. That’s the state database that tracks compliance. Your truck is now legal to operate in California until your next test is due. If there’s an issue, we’ll walk you through what needs to be fixed and can retest once repairs are complete.
The whole process takes about 15 minutes per truck. If you’ve got a fleet, we can knock out multiple vehicles in one visit and offer volume pricing that makes sense for your operation.
Ready to get started?
You get a CARB credentialed technician who shows up on time with certified testing equipment. We run the OBD test, verify your truck’s emissions data meets California standards, and issue your official CTC certificate if you pass.
Your results are uploaded to the CTC-VIS system the same day, so DMV has what they need to keep your registration active. You’ll also get a copy of your certificate for your records—keep it in the truck in case you’re ever pulled over or audited.
Valle Vista sits in Riverside County, where commercial trucking is a big part of the local economy. Whether you’re hauling construction materials, running a landscaping operation, or managing a delivery fleet, staying compliant with CARB truck regulations isn’t optional. The state started enforcing Clean Truck Check requirements on January 1, 2025, and testing deadlines are twice a year for most trucks. Starting in October 2027, OBD-equipped vehicles will need testing quarterly.
We also offer mobile service throughout the Valle Vista area, so you don’t lose time driving to a testing station. If you’ve got trucks parked at a yard, warehouse, or job site, we’ll come to you. That’s less downtime, less disruption, and fewer logistical headaches for your team.
Yes. If your truck operates in California, it needs to be compliant with the Clean Truck Check program—even if it’s registered in Nevada, Arizona, or anywhere else.
CARB regulations apply to all heavy-duty trucks over 14,000 pounds GVWR that drive on California public roads and highways. It doesn’t matter where your truck is registered or where your business is based. If you’re operating here, you’re subject to the same testing requirements as California-registered trucks.
That means twice-yearly emissions testing for 2013 and newer diesel trucks, and your vehicle must be reported in the CTC-VIS system before it’s allowed to operate legally. Out-of-state operators get caught off guard by this all the time, so if you’re running trucks through Valle Vista or anywhere in California, make sure you’re compliant before you hit the road.
Pricing varies depending on whether you’re bringing your truck to us or using our mobile service. A single-vehicle test typically runs between $75 and $150, and mobile testing comes with an additional service fee.
If you’ve got multiple trucks, we offer fleet pricing that brings the per-vehicle cost down. It’s worth asking about volume discounts if you’re managing more than a handful of vehicles—especially if you’re testing on a regular schedule.
The cost of the test is a lot easier to swallow than the alternative. CARB can fine you up to $10,000 per vehicle per day for non-compliance, and DMV will put a registration hold on your truck if you miss your testing deadline. One penalty wipes out years of testing costs, so staying on top of it is the smarter move financially.
If your truck fails, you’ll need to get it repaired and retested before it can legally operate in California. We’ll give you a report that shows exactly what triggered the failure—usually it’s an emissions system issue flagged by the OBD system.
You’ll want to take that report to a qualified diesel mechanic who can diagnose and fix the problem. Common issues include faulty sensors, DPF problems, or engine performance issues that cause your truck to exceed emissions limits. Once repairs are done, we can retest your truck and issue your certificate if it passes.
Don’t ignore a failed test. Operating a non-compliant truck puts you at risk for fines, registration holds, and potential roadside inspections that can sideline your vehicle. Get it fixed, get it retested, and get back to work legally.
Right now, most trucks need testing twice a year. Your specific testing schedule depends on your truck’s model year, engine type, and GVWR, but if you’re running a 2013 or newer diesel over 14,000 pounds, plan on semi-annual testing.
Starting in October 2027, the state is increasing the frequency to quarterly testing for OBD-equipped vehicles. That means four times a year instead of two. It’s part of CARB’s push to reduce emissions from heavy-duty trucks and improve air quality across California.
You’ll get reminders from the state when your testing deadline is coming up, but it’s smarter to stay ahead of it. Set your own reminders, track your testing dates, and schedule your next test before you’re up against a deadline. Missing a test date can trigger penalties and registration issues that are way more expensive than just staying compliant.
No. Clean Truck Check testing with OBD devices only applies to diesel trucks that are model year 2013 or newer. If your truck is a 2010, 2011, or 2012 model, it’s subject to different CARB testing requirements—but not the OBD-based Clean Truck Check we provide.
Older trucks may still need periodic smoke opacity testing or other emissions inspections depending on their weight and use, but that’s a different process. You’ll want to check with CARB or another testing provider to find out what applies to your specific vehicle.
This is a common point of confusion, so make sure you know your truck’s model year and GVWR before you schedule testing. If you’re not sure whether your truck qualifies, give us a call and we’ll walk you through it. We’d rather answer your questions up front than waste your time scheduling a test you don’t actually need.
Yes. We bring the testing equipment to your location in Valle Vista—whether that’s your business, a job site, or wherever your trucks are parked. Mobile testing saves you time and keeps your trucks working instead of sitting at a testing station.
We service fleets, owner-operators, and commercial truck operations throughout Riverside County. If you’ve got multiple trucks, mobile testing makes even more sense because we can test your whole fleet in one visit without disrupting your schedule.
Mobile service does come with an additional fee, but most operators find it’s worth it when you factor in the cost of downtime and lost productivity. If you’re interested in mobile testing or want to schedule a fleet appointment, reach out and we’ll get you on the calendar.
