Hear from Our Customers
You’re running a tight operation in San Jacinto’s logistics-heavy market. Your trucks need to move freight, not sit waiting for compliance testing. A single DMV registration hold costs you real money—over $1,000 per day, per vehicle in fines, plus the revenue you’re not generating while that truck sits idle.
California’s Clean Truck Check program requires semi-annual testing for diesel trucks model year 2013 or newer with a GVWR over 14,000 pounds. Miss a deadline and you’re looking at registration holds that shut down your operation. The state doesn’t care if you didn’t know or forgot—they just want compliance.
We handle CARB diesel compliance testing the way it should work: fast, mobile, and without the runaround. You schedule a time that works for your operation. We show up with CARB-certified OBD testing equipment. The digital inspection takes less than five minutes. Results go straight to CARB electronically, and you get a copy for your records.
No driving to a testing facility. No waiting in line. No wondering if your truck will pass or if you’ll face expensive repairs. Just straightforward heavy-duty vehicle compliance that keeps your fleet moving and your business running.
We bring over 25 years of owner-operator experience to every Clean Truck Check we perform in San Jacinto. We’re not just testers reading off a checklist—we’ve dealt with CARB regulations firsthand and understand what compliance actually means for your bottom line.
San Jacinto’s economy runs on logistics and transportation. With 572+ carriers operating in the area and major highways running through town, this community depends on trucks that can legally operate in California. We built this service specifically for operators like you who need reliable CARB truck regulations expertise without the hassle.
Our testers are CARB credentialed and use state-approved OBD testing devices that integrate directly with the CTC-VIS portal. We’ve handled everything from single owner-operators to fleets with 1,000+ vehicles. Whether you’re based here or just passing through California, we make sure your 2013 or newer heavy-duty trucks meet state requirements so you can focus on what you do best.
You reach out and tell us how many trucks need testing and where they’re located. We’re mobile across California, so whether your fleet is parked in San Jacinto or you need us at a different location, we come to you.
We schedule a time that doesn’t disrupt your operations. Early morning before a haul, late afternoon after deliveries, weekends—whatever works for your schedule. Our testers show up with CARB-certified OBD inspection equipment ready to go.
The actual testing takes less than five minutes per truck. We plug into your vehicle’s onboard diagnostics system, run the emissions check, and verify compliance with current CARB HD I/M testing standards. No smoke opacity tests, no guesswork—just clean digital data.
Results transmit electronically to CARB’s system immediately. You receive a copy for your records showing your truck passed and is compliant for the next six months. Your vehicle stays in the CTC-VIS database as current, which means no DMV registration holds and no compliance issues if you hit a CHP scale or need port access.
If something does flag during testing, we’ll tell you exactly what the issue is and what needs to happen next. No surprises, no unclear next steps—just straight information so you can make decisions quickly.

This service applies specifically to diesel or alternative fuel trucks model year 2013 or newer with a GVWR over 14,000 pounds. That’s not our rule—that’s California CARB compliant requirements for OBD-equipped vehicles. Older trucks and lighter vehicles fall under different testing programs.
You get mobile testing anywhere in California, which matters when you’re managing routes through San Jacinto and beyond. No need to route trucks to a specific facility or lose productive hours waiting for an appointment slot. We work around your schedule and location.
Every test we perform is conducted by CARB credentialed testers using approved equipment. The $31.18 annual compliance fee for 2025 gets paid to the state—that’s separate from our testing service. What you’re paying us for is the expertise, equipment, and convenience that keeps your operation compliant without the headaches.
Testing is required every six months right now. Starting October 2027, OBD-equipped vehicles will need testing four times per year. That’s more frequent compliance checks, which makes having a reliable testing service even more important. We’re set up to handle that increased demand without making it complicated for you.
If you’re an out-of-state operator running loads through California, you still need to comply. Your truck’s registration state doesn’t matter—if you’re operating on California public roads, you’re subject to CARB clean truck check requirements. We handle plenty of out-of-state trucks and can walk you through exactly what you need to stay legal here.
If your truck doesn’t pass, we’ll tell you exactly what flagged and why. The OBD system identifies specific issues—usually related to emissions controls, sensor malfunctions, or incomplete readiness monitors.
You’ll need to get the problem fixed before we can retest. Most issues involve repair work at a qualified diesel mechanic or dealership. Once repairs are complete and the vehicle’s computer shows all systems ready, we come back and retest.
The state doesn’t penalize you for a failed test during your compliance window. The penalty comes if you continue operating a non-compliant vehicle or miss your testing deadline entirely. Get it fixed, get retested, and you’re back in compliance. We’ll work with your timeline to make the retest as convenient as the first attempt.
California requires Clean Truck Check testing every six months for diesel trucks model year 2013 or newer with a GVWR over 14,000 pounds. Your testing deadline is based on when your vehicle was first reported in the CTC-VIS system.
You should receive notification from CARB before your deadline, but don’t rely on that. Check your last test date and count forward six months. Missing a deadline triggers a DMV registration hold, which grounds your truck immediately.
If you’re not sure where you stand, we can help you look up your vehicle’s status in the CTC-VIS portal. Better to check early and schedule testing with time to spare than scramble at the last minute or worse, find out you’re non-compliant when a CHP officer pulls you over at a scale.
Yes. If your truck operates on California public roads, it must comply with CARB regulations regardless of where it’s registered. That includes trucks just passing through or making occasional deliveries into the state.
Your vehicle needs to be reported in the CTC-VIS system and show current compliance before operating here. The state doesn’t give exemptions based on registration location. Out-of-state carriers face the same penalties for non-compliance—DMV holds and fines up to $1,000 per day, per vehicle.
We work with out-of-state operators regularly. The process is the same: we perform the CARB certified smog check, submit results electronically, and you get documentation showing compliance. If you run California routes even occasionally, it’s worth getting this handled before you have issues at a port, scale, or border inspection.
The actual OBD inspection takes less than five minutes per truck. We plug into your vehicle’s diagnostic port, run the emissions check through our CARB-certified equipment, and pull the data. It’s a digital process—no waiting for warm-up cycles or multiple test runs.
What takes longer is scheduling and logistics, especially if you’re coordinating testing for multiple vehicles. That’s why mobile service matters. We come to your yard, terminal, or wherever your trucks are parked. You don’t lose hours driving to a facility and waiting in line.
From the time we arrive to the time we’re done and you have documentation, figure 10-15 minutes per vehicle including setup. For a small fleet, we can knock out several trucks in under an hour. Larger fleets take longer, but we’re still talking about minimal disruption to your operation compared to traditional smog test facilities.
Clean Truck Check is specifically for heavy-duty diesel trucks—vehicles with a GVWR over 14,000 pounds and model year 2013 or newer. Regular smog checks are for passenger vehicles and lighter trucks. They’re completely different programs with different equipment, different testers, and different reporting systems.
Clean Truck Check uses OBD-based testing that reads data directly from your truck’s computer. It checks emissions controls, sensor functionality, and system readiness. Regular smog checks for older or lighter vehicles might use tailpipe sensors or visual inspections. The testing equipment isn’t interchangeable.
You can’t just go to any smog check station for Clean Truck Check service. The tester needs to be CARB credentialed specifically for heavy-duty vehicle compliance, and they need the right OBD testing device that connects to the CTC-VIS portal. That’s why this is a specialized service—most general smog shops don’t have the certification or equipment to handle it.
Yes, as long as you’re still within your compliance window. If your testing deadline hasn’t passed yet, your truck can legally operate while you arrange testing. The problem comes when you miss the deadline—that’s when DMV registration holds kick in and your truck gets grounded.
Once we complete your test, results transmit to CARB electronically right away. There’s no waiting period for approval or processing. If your truck passes, it’s immediately compliant in the state system. You can verify the updated status in CTC-VIS within minutes.
If you’re cutting it close to a deadline, don’t wait. Schedule testing with enough buffer time to handle any potential issues. If something does flag and you need repairs, you want time to get that done and retest before your compliance window closes. Operating a non-compliant vehicle after your deadline isn’t just risky—it’s expensive and can shut down your entire operation.
