You’re not looking for someone to explain regulations. You need your trucks tested, certified, and back on the road.
Starting January 2025, every diesel truck over 14,000 pounds GVWR needs to pass CARB emissions testing. Miss your deadline and the DMV puts a hold on your registration. That means your truck sits, you lose money, and your customers start calling someone else.
The testing itself checks your OBD system through the J1937 or J1979 connector. If your truck passes, the results upload directly to the state’s CTC-VIS database. Your compliance deadline gets updated. Your DMV record clears. You’re legal to operate in California for another six months.
If your truck doesn’t pass, you know exactly what needs fixing before you waste time or money guessing. No surprises. No runaround.
We handle CARB compliance testing for commercial trucks throughout Mecca and the surrounding Coachella Valley. We’re CARB credentialed, which means the state accepts our test results without question.
Most of our customers run small fleets or owner-operator rigs. They’re hauling produce, freight, or equipment through Southern California and need their compliance handled fast so they can get back to work. We get that.
We’ve been doing emissions testing in Riverside County long enough to know what breaks, what passes, and what actually matters when it comes to keeping your trucks compliant. You’re not our first rodeo with CARB diesel compliance requirements.
First, we verify your truck qualifies. That means model year 2013 or newer with a GVWR over 14,000 pounds. If it’s older or lighter, this testing doesn’t apply to you.
Next, we connect our CARB certified testing device to your truck’s OBD port. The scan pulls data from your engine’s emissions system and checks it against California’s standards. This takes about 15 to 30 minutes depending on your truck’s setup.
If everything checks out, your results upload immediately to the CTC-VIS system. You get a TRUCRS certificate proving compliance. Your next deadline gets set for six months out. Your DMV record updates automatically within a few days.
If something fails, we’ll tell you exactly what triggered it. Sometimes it’s a sensor. Sometimes it’s a regen issue. Sometimes it’s something you can fix yourself. Either way, you’ll know what you’re dealing with before you spend a dime on repairs.
We can come to your location in Mecca if that’s easier. Mobile testing starts at $79 per truck if you pass. You don’t pay if the truck fails.
Ready to get started?
You get a compliance test performed by a CARB credentialed tester using state-approved equipment. That’s the baseline. Without that credential, your test results don’t count.
You also get same-day results uploaded to the CTC-VIS database. No waiting weeks for paperwork. No wondering if the state received your information. It’s done digitally and it’s instant.
If your truck passes, you receive a TRUCRS certificate. That’s your proof of compliance if you get pulled over or if a customer asks for verification. Some shippers won’t hire non-compliant carriers because they face fines up to $10,000 per violation.
In Mecca and throughout Riverside County, most of the trucks we test are hauling agricultural products or freight through the I-10 corridor. CARB enforcement has been increasing along these routes, especially near weigh stations and inspection points. Getting caught without compliance costs more than just the fine. It costs you loads, relationships, and credibility.
We also help you track your deadlines. The semi-annual testing schedule confuses a lot of people because it’s not based on the calendar year. Your deadline is specific to your truck and gets calculated in your CTC-VIS account. Miss it by even a day and you’re facing a registration hold.
Yes. If your truck operates in California, it needs to comply regardless of where it’s registered.
CARB’s regulations apply to nearly all diesel and alternative fuel vehicles over 14,000 pounds GVWR that operate on California roads. That includes out-of-state trucks, privately owned trucks, government vehicles, and commercial fleets. The only exceptions are very specific vehicle types like emergency vehicles or certain agricultural equipment.
If you’re hauling loads into or through California, you’re subject to the Clean Truck Check program. That means you need a passing emissions test on file and an active compliance deadline in the CTC-VIS system. CARB can and does check compliance at weigh stations, inspection points, and through roadside monitoring. Getting flagged without compliance leads to citations, fines, and potential impoundment.
Every six months. Your compliance deadline is semi-annual and specific to each vehicle.
When you first enter the Clean Truck Check program, you’ll get assigned an initial deadline based on your truck’s VIN and registration details. After you pass your first test, your next deadline gets set for six months later. This cycle continues as long as you operate in California.
Your exact deadline date is calculated and tracked in your CTC-VIS account. It’s not January 1st and July 1st for everyone. It’s unique to your truck. You can submit a passing test up to 90 days before your deadline, which gives you some flexibility for scheduling. But if you miss your deadline, the DMV will place a registration hold on your vehicle. That hold stays in place until you test and pass.
We connect a CARB certified device to your truck’s OBD system and scan the emissions data. The device reads fault codes, monitors, and readiness status from your engine’s computer.
For 2013 and newer diesel engines, the OBD system tracks everything related to emissions controls. That includes your DPF, SCR system, EGR valve, NOx sensors, and more. The scan checks whether these systems are functioning properly and whether your truck is operating within California’s emissions standards.
The test doesn’t measure tailpipe emissions like older smog checks. It’s all diagnostic data pulled directly from your engine. If your check engine light is on, if you have active fault codes, or if certain monitors haven’t completed their readiness cycles, your truck will fail. If everything checks out, the results upload immediately and you’re compliant. The whole process takes 15 to 30 minutes in most cases.
Yes. We offer mobile testing throughout Mecca and the surrounding areas in Riverside County.
Mobile service makes sense if you’re running multiple trucks or if bringing your rig to a shop creates scheduling problems. We bring the same CARB certified testing equipment to your yard, warehouse, or wherever your trucks are parked. The test works exactly the same way. The results upload the same way. You just don’t have to drive anywhere.
Pricing for mobile testing starts at $79 per truck that passes. If a truck fails, you don’t pay for that test. We’ll explain what caused the failure and you can decide whether to fix it yourself or have us handle the repairs. Once it’s fixed, we can retest on the spot or schedule another visit. Mobile service is especially popular with agricultural operations around Mecca and the Coachella Valley where trucks are spread across multiple locations.
You’ll get a detailed report showing exactly what caused the failure. Most failures are fixable.
Common issues include active fault codes, incomplete monitor readiness, DPF problems, or SCR system malfunctions. Sometimes it’s as simple as your truck needing a forced regen. Sometimes it’s a faulty sensor that’s throwing a code. Sometimes it’s a bigger issue with your emissions equipment.
We’ll walk you through what the scan found and what it means. If it’s something you can handle, we’ll tell you. If it needs professional repair, we can take care of it or you can take it to your regular mechanic. Once the issue is fixed, you’ll need to retest. There’s no limit on how many times you can test, but you need a passing result before your compliance deadline or you’re facing a DMV registration hold. The key is addressing failures early so you’re not scrambling at the last minute.
Your truck qualifies if it’s model year 2013 or newer and has a GVWR over 14,000 pounds. That’s the requirement for this specific testing program.
Older trucks or lighter vehicles fall under different regulations or may not be subject to the Clean Truck Check program at all. The 2013 cutoff exists because that’s when OBD systems became standard on heavy-duty diesel engines. The testing relies on pulling data from that OBD system, so older trucks without those systems can’t be tested this way.
If you’re not sure about your truck’s GVWR, check the door placard or your registration. If you’re right around 14,000 pounds, it’s worth verifying before you schedule testing. We can help you figure it out based on your VIN. The last thing you want is to show up for a test only to find out your truck doesn’t qualify or needs a different type of compliance check.
