Your trucks stay registered. Your drivers stay on schedule. Your business doesn’t get hit with thousand-dollar-per-day penalties that stack up faster than you can write the check.
CARB compliance isn’t optional for trucks over 14,000 pounds GVWR built in 2013 or newer. Miss a deadline and the DMV won’t renew your registration. Miss it long enough and you’re looking at fines that start at $1,000 per vehicle per day and can climb to $10,000. That’s not a scare tactic—it’s what happens when California catches a non-compliant truck operating on state roads or trying to access ports.
We come to you in Santa Clarita with mobile clean truck check testing. You schedule it, we show up, we run the OBD test, and your results go straight to CARB’s system. No waiting at a shop. No pulling trucks off routes for half a day. You stay compliant, your fleet stays moving, and your registration stays active.
We’ve been handling heavy-duty truck inspections and diesel emissions testing in Santa Clarita for nearly two decades. We’re not new to CARB regulations, and we’re not figuring this out as we go.
Santa Clarita sits right on I-5 and SR-14, which means your trucks are moving freight to and from the ports, through the valley, and across state lines. We know what compliance looks like for fleets operating in this corridor. We know the deadlines, the testing requirements, and how to get your trucks certified without pulling them off the road longer than necessary.
Our techs are licensed and certified to perform Clean Truck Check testing. Every test we run meets state and federal standards, and every result gets transmitted directly to CARB so your compliance record updates in real time.
You call or message us with your truck details—year, make, VIN, and location in Santa Clarita. We confirm your vehicle qualifies (2013 or newer, over 14,000 pounds GVWR), and we schedule a time that works for your operation.
We show up with our equipment and run the OBD-based Clean Truck Check test on-site. The test pulls data directly from your truck’s onboard diagnostics to verify emissions system performance. It takes minutes, not hours.
Once the test is complete, we transmit your results electronically to CARB’s TRUCRS system. You get documentation showing your truck passed, and your compliance deadline gets updated in the state database. If your truck doesn’t pass, we’ll tell you exactly what’s flagged and what needs attention before you can retest.
You don’t need to track down a certified shop or take your truck out of service for the day. We handle the testing wherever your trucks are parked in Santa Clarita, and you get same-day results that keep your fleet California CARB compliant.

Every CARB compliance test we perform includes the full OBD Clean Truck Check required by California’s HD I/M program. That means we’re checking your truck’s emissions control systems, verifying they’re working as designed, and confirming your vehicle meets the standards CARB enforces for heavy-duty diesel trucks operating in the state.
You’ll receive a TRUCRS certificate showing your truck passed inspection. That certificate is your proof of compliance if you’re ever stopped or audited. We also make sure your compliance record is updated in CARB’s database so the DMV doesn’t flag your registration.
Santa Clarita’s location makes it a hub for trucks moving between LA, the ports, and northern California. If your trucks run those routes, you’re operating in some of the most heavily monitored corridors in the state. CARB enforcement is active here, and non-compliant vehicles get caught—especially at weigh stations, port entries, and during roadside inspections. Our mobile service keeps you ahead of that.
The annual compliance fee for 2025 is $31.18 per vehicle, and that’s separate from our testing service. Starting this year, compliance deadlines happen twice a year. In three years, that increases to four times annually. The requirements aren’t getting lighter—they’re getting stricter. Getting tested on time isn’t just about avoiding penalties. It’s about keeping your trucks legally operational in California.
Only heavy-duty trucks with a gross vehicle weight rating over 14,000 pounds that are model year 2013 or newer. If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this program doesn’t apply to you.
CARB’s Clean Truck Check program is specific. It’s not a general smog check for all vehicles. It’s an emissions compliance test for newer heavy-duty diesel trucks operating in California. If you’re running a semi truck, a heavy-duty pickup used commercially, or any truck that falls into that weight and year range, you’re required to test.
Out-of-state trucks count too. If your truck is registered outside California but operates here regularly, you still need to comply. CARB doesn’t care where your plates are from—if you’re driving on California roads and you meet the criteria, you’re subject to the same rules as in-state operators.
You’ll get a report showing exactly what triggered the failure—usually a fault code or emissions system malfunction detected through the OBD test. You’ll need to get that issue repaired before you can retest and receive your compliance certificate.
A failed test doesn’t mean your truck is off the road permanently, but it does mean you can’t legally operate it in California until it passes. The DMV won’t renew your registration, and if you’re caught driving a non-compliant vehicle, you’re looking at penalties. Most failures are related to diesel particulate filters, NOx sensors, or exhaust system malfunctions.
Once repairs are done, you retest. We can come back out to your location in Santa Clarita and run the test again. If everything checks out, your results go to CARB and you’re compliant. The key is addressing failures quickly—every day you wait is another day your truck can’t legally run routes in California.
Right now, compliance deadlines happen twice a year per vehicle. In three years, that increases to four times annually. Your specific deadlines are assigned by CARB based on your vehicle’s VIN and registration details.
You can check your compliance due dates through CARB’s TRUCRS system online. Missing a deadline triggers a registration hold with the DMV, which means you can’t renew your truck’s registration until you test and pass. That’s not something you can ignore or push back—the state won’t process your renewal until your compliance record is current.
The testing schedule is getting tighter, not looser. CARB is ramping up enforcement, and the frequency of required tests is increasing as the program matures. If you’re running multiple trucks, you need a system to track deadlines for each vehicle. We work with fleets in Santa Clarita to stay ahead of compliance dates so nothing slips through.
Yes. We bring mobile CARB emissions testing directly to your location anywhere in Santa Clarita. You don’t need to drive your truck to a shop or take it out of service for half a day.
Our mobile setup is fully equipped to perform the OBD Clean Truck Check on-site. Whether your trucks are parked at your yard, a job site, or a terminal, we come to you. That’s especially useful for fleets with multiple vehicles that need testing around the same deadline—we can knock them out in one visit.
Santa Clarita’s layout and the nature of heavy-duty truck operations here make mobile testing the most practical option. Your trucks are working. They’re on tight schedules. Pulling them off routes to sit at a shop doesn’t make sense when we can test them where they’re already parked. You save time, we keep the process efficient, and your trucks stay compliant without unnecessary downtime.
Our mobile Clean Truck Check service is competitively priced with other certified providers in the Santa Clarita area. Exact pricing depends on how many trucks you need tested and your location, but you’re looking at a cost that’s a fraction of what you’d pay in fines for non-compliance.
For context, CARB penalties start at $1,000 per vehicle per day and can reach $10,000 daily for repeat or severe violations. A single missed deadline that goes unresolved for a week could cost you more than a year’s worth of compliance testing for your entire fleet. The test itself is a small expense compared to the financial and operational risk of skipping it.
The annual compliance fee CARB charges is separate—$31.18 per vehicle for 2025, increasing to $32.13 in 2026. That fee goes to the state, not to us. Our service covers the actual testing, documentation, and electronic submission of results to CARB’s system. You’re paying for certified testing that keeps your trucks legal and your registration active.
A regular smog check is for passenger vehicles and light-duty trucks under 14,000 pounds. CARB compliance testing—specifically the Clean Truck Check—is for heavy-duty vehicles over 14,000 pounds GVWR built in 2013 or newer. They’re completely different programs with different testing methods and requirements.
The Clean Truck Check uses OBD diagnostics to evaluate your truck’s emissions control systems. It’s not a tailpipe test. It’s a computer-based check that pulls fault codes and system performance data directly from your truck’s onboard computer. If your emissions systems aren’t functioning properly, the test will catch it.
You can’t take a heavy-duty truck to a standard smog check station and expect them to handle CARB compliance. They’re not equipped for it, and they’re not certified under the HD I/M program. You need a provider like us that’s specifically certified to perform Clean Truck Check testing for commercial vehicles. That’s what we do in Santa Clarita—heavy-duty diesel compliance, not passenger car smog checks.
