You’re running a business, not chasing paperwork. When your trucks are CARB compliant, the DMV doesn’t freeze your registrations. You don’t get letters saying your truck was caught smoking on I-215. Your drivers don’t get pulled over and sidelined for emissions failures.
That’s what compliance actually does for you. It keeps your fleet moving, your schedule intact, and your operation off CARB’s radar.
If you’re operating 2013 or newer heavy-duty trucks over 14,000 pounds in Woodcrest, this isn’t optional anymore. CARB’s Clean Truck Check program requires OBD emissions testing, and they’re actively monitoring roadside. The trucks that don’t comply get flagged, tested, and if they fail, they’re grounded until you fix it. That’s lost revenue, missed deliveries, and a headache you don’t need.
We focus exclusively on CARB compliance for heavy-duty diesel trucks—2013 and newer, over 14,000 pounds GVWR. That’s it. We’re not a general repair shop trying to do everything. We’re credentialed by CARB, we use certified OBD testing equipment, and we know exactly what the state requires because we do this every day.
Woodcrest sits right in the middle of Riverside County’s logistics corridor. You’ve got trucks running between Ontario, Perris, Moreno Valley, and the Inland Empire distribution hubs. That means you’re on roads where CARB monitors emissions, and you’re subject to the same Clean Truck Check rules as every other fleet in California.
We’re here because this community runs on commercial transportation, and those operators need a local shop that understands the regulations without the runaround.
You bring your 2013+ heavy-duty truck to our Woodcrest location. We plug into the OBD port using CARB-certified diagnostic equipment and pull the emissions data directly from your engine’s computer. This isn’t a visual inspection or a guess—it’s a digital readout of how your truck’s emissions control systems are performing.
If your truck passes, we submit the results directly to CARB’s database. You get a compliance certificate, and your DMV record gets updated. The whole process typically takes under an hour, and you’re back on the road with proof of compliance.
If something flags during testing, we’ll tell you exactly what the issue is. You’ll need to get it repaired, then come back for a retest. CARB gives you a 30-day window once you’re notified, so timing matters. We don’t do the repairs ourselves, but we’ll point you in the right direction and retest once the work is done.

You’re paying for certified OBD emissions testing using equipment that meets CARB’s standards. You’re also paying for a credentialed technician who knows how to read the data, submit it correctly, and make sure your compliance record is clean. That’s what keeps your registration active and your trucks legal to operate in California.
In Woodcrest and across Riverside County, CARB has roadside monitoring stations that flag high-emitting trucks. If your truck gets flagged, you’ll receive a Notice to Submit to Testing. You’ve got 30 days to get it done, or your registration gets frozen. Our testing satisfies that requirement.
This service applies only to trucks that are model year 2013 or newer and have a gross vehicle weight rating over 14,000 pounds. If your truck is older or lighter, this isn’t the test you need. CARB’s Clean Truck Check program is specifically designed for newer heavy-duty diesel engines equipped with OBD systems, and that’s the only segment we test.
Starting in 2025, testing is required twice a year. By October 2027, that increases to four times a year. The requirements aren’t getting looser—they’re tightening. If you’re running a fleet in California, this is part of your operating cost now.
If your truck fails, CARB won’t let you renew your registration until you fix the issue and pass a retest. The test results get submitted directly to the state, so there’s no hiding it or delaying it. You’ll receive documentation showing what failed—usually it’s a sensor, a DPF issue, or something with the emissions control system.
You’ll need to take your truck to a qualified repair shop that can diagnose and fix the problem. We don’t do the repairs, but once the work is done, you bring it back to us for a retest. CARB gives you 30 days from the date of the failure notice to submit passing results. If you miss that window, your registration gets frozen and your truck is legally grounded.
The cost of repairs depends entirely on what’s wrong. A sensor might be a few hundred dollars. A DPF replacement can run several thousand. That’s why it’s worth staying on top of maintenance before you’re forced into testing.
Right now, if you’re operating a 2013 or newer heavy-duty truck over 14,000 pounds GVWR, you need to test twice a year. That’s the current requirement under CARB’s Clean Truck Check program, which started in 2023 and became fully enforceable in 2025.
By October 2027, that frequency increases to four times a year for OBD-equipped vehicles. CARB is tightening the testing schedule to catch emissions issues faster and keep high-polluting trucks off the road. You can submit passing test results up to 90 days before your compliance deadline, so if you’re organized, you can stay ahead of it.
If you get flagged by one of CARB’s roadside monitoring stations, you’ll receive a separate notice requiring you to test within 30 days, regardless of your regular schedule. That’s on top of your normal testing cycle, and it’s non-negotiable. Miss it, and your registration gets frozen.
No. This specific testing requirement only applies to heavy-duty trucks that are model year 2013 or newer and have a gross vehicle weight rating over 14,000 pounds. If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, you’re not subject to the Clean Truck Check program.
The 2013 cutoff matters because that’s when OBD systems became standard on heavy-duty diesel engines. CARB’s testing relies on pulling data directly from the truck’s onboard diagnostics, so older trucks without that technology aren’t part of this program. They may still have other emissions requirements, but not this one.
If you’re running a mixed fleet, you need to know which trucks fall under Clean Truck Check and which don’t. The newer, heavier trucks are the ones CARB is focused on, and those are the ones that need testing twice a year starting now, increasing to four times a year by 2027.
No. Regular smog shops that test passenger cars and light-duty trucks aren’t equipped to handle heavy-duty CARB compliance testing. This requires CARB-certified OBD diagnostic equipment specifically designed for trucks over 14,000 pounds, and it requires a technician who’s credentialed by CARB to perform the test.
The equipment is different, the software is different, and the reporting process is different. CARB maintains a list of approved testing stations, and if you go somewhere that’s not certified, the test won’t count. You’ll have wasted your time and your money, and you’ll still be out of compliance.
We’re certified to perform this testing. We have the equipment, the credentials, and the direct connection to CARB’s database to submit your results. When you leave here with a passing certificate, it’s legitimate and it’s on record with the state.
CARB will place a registration hold on your vehicle, which means you can’t renew your registration and you can’t legally operate the truck in California. If you’re caught driving with an expired registration due to a compliance hold, you’re looking at fines, potential impoundment, and a lot of downtime while you sort it out.
If you’re a fleet operator, the consequences get worse. Shippers who hire non-compliant carriers can be fined up to $10,000 per year for each non-compliant truck. That means your customers might refuse to work with you if your compliance isn’t up to date. Ports and railyards can also deny entry to trucks that aren’t compliant.
CARB isn’t bluffing on enforcement. They have roadside monitoring stations, they send violation notices, and they actively track which trucks are complying and which aren’t. If you’re running a business that depends on keeping your trucks on the road, this isn’t something you can ignore or put off.
The actual testing process usually takes less than an hour. We plug into your truck’s OBD port, run the diagnostics, pull the emissions data, and submit it to CARB’s database. If everything checks out, you get your compliance certificate and you’re done.
The timing can vary slightly depending on how quickly the truck’s computer communicates with our equipment, but it’s a straightforward process. You’re not waiting around all day. Most operators drop off their truck, grab coffee, and pick it up within the hour.
If your truck fails, that’s when things take longer—not because of the test itself, but because you’ll need to get repairs done and come back for a retest. That’s why it’s worth making sure your emissions systems are in good shape before you come in. Preventive maintenance saves you time and money compared to scrambling to fix something after a failed test.
