You’re not looking for a lecture about California regulations. You need your heavy-duty trucks tested, compliant, and back on the road—fast.
Here’s what that looks like: No DMV registration holds blocking your renewals. No $10,000-per-vehicle-per-day penalties eating into your operating budget. No surprise enforcement stops from CHP or CARB’s roadside monitoring devices shutting you down mid-route.
Your 2013 or newer diesel truck gets tested using certified OBD equipment. Results upload directly to CARB’s system. You get proof of compliance. Your trucks stay legal, and your business keeps moving.
That’s the outcome. We handle the CARB diesel compliance requirement so you can focus on the work that actually pays.
We serve the Homeland trucking community with CARB credentialed testing right here on US Highway 74. We’re not some distant facility that makes you drive an hour out of your way.
You’re dealing with a local shop that knows Riverside County operators face tight deadlines and can’t afford downtime. We use California Air Resources Board certified OBD testing devices and upload results directly to the CTC-VIS system the same day.
Our testers hold current CARB credentials. We know the HD I/M program requirements inside and out. And we’re here because Homeland needed a reliable option for heavy-duty vehicle compliance that doesn’t waste your time.
First, you bring your 2013 or newer heavy-duty truck to our facility in Homeland. This service only applies to trucks with a GVWR over 14,000 pounds—so if your truck is older than 2013 or lighter than that threshold, this isn’t the right test.
Our CARB credentialed tester connects a certified OBD testing device to your truck’s diagnostic port. The device reads emissions data directly from your truck’s onboard computer. For 2013 and newer diesel engines, this is how California verifies compliance with CARB truck regulations.
The test takes about 15 to 30 minutes. Once complete, we upload your results directly to CARB’s database. You’ll get documentation showing your truck passed, and that data goes straight into the CTC-VIS system.
You can submit a passing test up to 90 days before your deadline, so you’re not scrambling at the last minute. If you’ve received a Notice to Submit to Testing, you have 30 calendar days to get it done—so don’t wait.
After testing, your truck is compliant for the next six months. You’ll need to repeat this process semi-annually to stay legal and avoid enforcement action.
Ready to get started?
You get CARB HD I/M testing performed by a credentialed professional using certified equipment. That’s not optional—it’s the only way to meet California’s requirements for trucks operating on public roads.
Your test results upload directly to the state system, so there’s no paperwork you have to mail in or file yourself. You walk away with proof your truck is compliant, and CARB has the data they need to keep your registration active.
In Homeland and across Riverside County, enforcement is real. CARB uses remote emissions monitoring devices, and CHP coordinates inspections. If your truck isn’t in the system as compliant, you’re risking penalties that start at $10,000 per vehicle per day. Registration blocks follow, and that means your truck sits until you fix it.
This isn’t just a smog check. It’s a state-mandated compliance program for heavy-duty diesel and alternative fuel vehicles. The $31.18 compliance fee goes to CARB, and testing must happen every six months. Missing a deadline doesn’t just cost you money—it can shut down your operation.
We handle the technical side so you stay ahead of deadlines, avoid enforcement, and keep your trucks where they belong: on the road and earning.
If your truck has a gross vehicle weight rating over 14,000 pounds and is powered by a 2013 or newer diesel engine, you need Clean Truck Check testing every six months. This also applies to 2018 and newer alternative fuel engines, including hybrids.
The program covers nearly all heavy-duty trucks, buses, and commercial vehicles operating in California—whether they’re registered in-state or out-of-state. It doesn’t matter if your truck is privately owned, part of a fleet, or a government vehicle. If it meets the weight and model year criteria, it’s required.
Older trucks and lighter vehicles don’t fall under this program. So if your truck is a 2012 or earlier model, or if it’s under 14,000 pounds GVWR, this isn’t the test you need. Don’t assume your truck qualifies without checking the specs.
You need to complete a Clean Truck Check test every six months. That’s the semi-annual requirement under California’s CARB HD I/M program, and it’s not negotiable.
The good news is you can submit a passing test up to 90 days before your compliance deadline. That gives you a three-month window to schedule testing without cutting it close. If you’re organized, you can get it done early and avoid the stress of last-minute appointments.
If you receive a Notice to Submit to Testing from CARB, you only have 30 calendar days to get a passing test submitted. Miss that window, and you’re looking at penalties and potential registration holds. The clock starts as soon as that notice goes out, so don’t sit on it.
You’ll face penalties up to $10,000 per vehicle per day for non-compliance. That’s not a scare tactic—that’s the actual enforcement structure under CARB regulations.
On top of financial penalties, CARB will place a registration hold with the DMV. That means you can’t renew your truck’s registration until you submit a passing test and pay the compliance fee. Your truck becomes illegal to operate on California roads, and you’re stuck until you fix it.
Enforcement isn’t passive, either. CARB uses roadside monitoring devices that can detect non-compliant trucks, and they coordinate with the California Highway Patrol for inspections. If you’re caught operating a non-compliant vehicle, the consequences stack up fast. It’s not worth the risk when testing takes less than half an hour.
We provide CARB certified Clean Truck Check testing right here in Homeland at 31200 US Highway 74. You don’t need to drive to Hemet, Perris, or Riverside to find a credentialed tester.
We’re set up specifically for heavy-duty vehicle compliance testing using CARB approved OBD equipment. Our testers hold current credentials, and we upload results directly to the CTC-VIS system the same day you test.
If you’re running trucks in Riverside County, having a local option matters. Less drive time means less downtime, and you’re not pulling trucks off routes for half a day just to stay compliant. We’re here because Homeland needed a reliable testing facility that understands how tight your schedule is.
The state-mandated compliance fee is $31.18, and that goes directly to CARB. That’s separate from the testing service fee, which covers the actual inspection, equipment use, and results upload.
Testing fees can vary depending on the facility, but you’re paying for certified equipment and a credentialed tester who knows how to handle OBD diagnostics on 2013 and newer heavy-duty trucks. This isn’t a standard smog test—it’s a specialized compliance program with specific requirements.
When you factor in the cost of penalties—$10,000 per vehicle per day—and the operational impact of a registration hold, the testing fee is a small price to pay. You’re not just buying a test. You’re buying the ability to keep your trucks legal and your business running without interruption.
Yes. You can submit a passing Clean Truck Check test up to 90 days before your compliance deadline. That’s a full three-month early testing window, and it’s one of the smartest ways to avoid last-minute stress.
Testing early means you’re not scrambling when your deadline hits. You’re not competing for appointment slots with other operators who waited too long. And if something comes up—your truck fails, or you need a repair—you’ve got time to handle it without penalties.
Once your passing test uploads to CARB’s system, your compliance clock resets for another six months. There’s no downside to testing early, and there’s a lot of upside. If you’re in Homeland and your deadline is approaching, don’t wait. Get it done now and move on.
