Hear from Our Customers
You’re running a business, and every day a truck sits idle costs you money. CARB compliance isn’t optional anymore—it’s enforced with daily fines up to $10,000 per vehicle and DMV registration holds that keep your trucks off the road until you fix it.
We handle CARB clean truck check testing for diesel trucks model year 2013 or newer with a GVWR over 14,000 pounds. That’s the service—nothing older, nothing lighter. If your truck fits those specs, we test it where it sits.
Mobile testing means we come to your location anywhere in Canyon Lake or across California. You schedule it, we show up, run the OBD scan and opacity test, and upload results to the state’s CTC-VIS system the same day. Your compliance status updates automatically with CARB and DMV. No waiting, no wondering if it went through.
You avoid the penalties, keep your registration current, and your trucks stay on the road doing what they’re supposed to do—making you money.
All SMOG Motors has been handling CARB compliance testing for heavy-duty diesel trucks across California for over five years. We’re state-licensed and CARB-credentialed, which means our test results are valid and accepted by the state—no questions, no rejections.
Canyon Lake sits in Riverside County, where trucking, construction, and logistics operations depend on staying compliant to access ports, terminals, and job sites. We’ve worked with fleets, owner-operators, and commercial vehicle owners throughout the area who need reliable testing without the runaround.
We’re not a shop you drive to. We’re a mobile service that comes to you, tests your equipment on-site, and handles the reporting so you can get back to work. That’s it.
First, you contact us and schedule a time that works for your operation. We come to your location in Canyon Lake or anywhere in California with our mobile testing equipment. Same-day service is available for most areas if you need it fast.
When we arrive, we run the required tests based on your truck’s year and engine type. For 2013 and newer diesel engines, that means an OBD data scan using CARB-certified testing devices. We also perform smoke opacity tests to measure visible emissions. The whole process takes about 20 to 30 minutes per vehicle.
Once testing is complete, we upload your results directly to the CTC-VIS system. That’s the state database that CARB and DMV use to track compliance. Your vehicle record updates instantly, and you’re done. If you’re managing multiple trucks, we offer fleet pricing and can test your entire operation in one visit.
You can submit test results up to 90 days before your compliance deadline, which gives you time to handle repairs if something doesn’t pass. Most operators use that window to stay ahead of deadlines instead of scrambling at the last minute.

CARB requires semi-annual testing for most heavy-duty diesel trucks. Starting in October 2027, OBD-equipped vehicles will move to quarterly testing. Every test costs $31.18 for the annual compliance fee, which we collect and submit to the state on your behalf.
You’re also paying for mobile service, which means no hauling trucks to a testing station and no waiting in line. We bring the equipment to your yard, job site, or wherever your trucks are parked. That saves you fuel, time, and the hassle of coordinating driver schedules.
Canyon Lake’s location near major California trucking corridors means CARB enforcement is active. Roadside monitoring devices and automated license plate readers are used to identify non-compliant vehicles. If you’re flagged, you’re looking at fines, registration holds, and potential denial of access to ports and terminals.
We test only what the state requires: 2013 or newer diesel trucks over 14,000 pounds GVWR. If your truck is older or lighter, this service doesn’t apply. But if it fits the criteria, we handle everything from testing to reporting so you stay compliant without the headaches.
Only diesel trucks that are model year 2013 or newer and have a gross vehicle weight rating over 14,000 pounds qualify for this testing. That includes commercial trucks, construction equipment, agricultural vehicles, and California-registered motorhomes that meet those specs.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, it doesn’t fall under the CARB clean truck check program. The state’s regulations are specific about which vehicles require testing, and we only test what’s mandated.
Out-of-state trucks operating in California are also subject to these requirements, regardless of where they’re registered. If you’re running trucks through California, you need to comply with CARB emissions testing or risk fines and registration issues.
Most heavy-duty diesel trucks require testing twice a year—that’s semi-annual. Your compliance deadlines are set by CARB based on your vehicle’s registration and previous test dates.
Starting in October 2027, trucks with OBD systems will move to quarterly testing, which means four times a year. That change is coming whether you’re ready or not, so it’s worth planning ahead.
You can submit passing test results up to 90 days before your deadline. That gives you a buffer to handle any repairs if your truck doesn’t pass on the first try. Most operators schedule early to avoid last-minute stress and potential penalties.
If your truck fails, you’ll need to get the emissions issue repaired and then retest. We’ll provide you with the test results that show what failed, so you know exactly what needs fixing.
Once repairs are done, we come back and retest the vehicle. If it passes, we upload the results to the state system and your compliance status updates. You have up to 90 days before your deadline to get this handled, which is why testing early matters.
If you don’t resolve the failure and miss your compliance deadline, CARB can place a registration hold on the vehicle. That means you can’t renew your registration until you pass the test, and the truck legally can’t operate on California roads.
Yes. If you’re managing multiple trucks, we offer discount pricing for fleet accounts. The more vehicles you need tested, the better the rate.
Fleet testing also means we can schedule one visit to test your entire operation at once. That’s more efficient for you and eliminates the need to coordinate multiple appointments. We handle everything on-site, test each truck, and upload all results the same day.
Contact us with the number of trucks you need tested and we’ll give you a quote. Most fleet operators in Canyon Lake and surrounding areas use our mobile service because it saves time and reduces downtime across their entire operation.
Each truck takes about 20 to 30 minutes to test, depending on the vehicle and engine type. That includes the OBD data scan and smoke opacity test.
If you have multiple trucks, we test them back-to-back during the same visit. A fleet of five trucks, for example, would take roughly two to three hours total. We work efficiently to minimize disruption to your operation.
Once testing is complete, we upload results to the CTC-VIS system immediately. You don’t have to wait days or weeks to find out if you’re compliant—it’s done before we leave your site.
Yes. CARB compliance applies to all heavy-duty diesel trucks operating in California, regardless of where they’re registered. If you’re an out-of-state operator running trucks through California, you’re required to comply with the same emissions testing rules as California-registered vehicles.
We test trucks from all states as long as they meet the criteria: model year 2013 or newer and over 14,000 pounds GVWR. The testing process is the same, and results are uploaded to the state system just like any other vehicle.
If you’re based outside California but operate here regularly, staying compliant protects you from fines, registration issues, and access restrictions at ports and terminals. We handle the testing wherever your trucks are located in California.
