You’re running a business. Your trucks need to move, not sit idle waiting for compliance paperwork. California’s Clean Truck Check program requires semi-annual emissions testing for heavy-duty vehicles—and if you miss it, you’re looking at registration holds, fines up to $1,000 per day per vehicle, and trucks that can’t legally operate.
That’s not a minor inconvenience. That’s revenue loss, missed deliveries, and frustrated customers asking where their shipment is.
We handle CARB compliance testing for model year 2013 and newer trucks with a GVWR over 14,000 pounds. We’re CARB-certified, which means your OBD test results go straight to the state electronically. You get documentation immediately. Your trucks stay compliant. Your operation keeps moving.
This isn’t about checking a box. It’s about protecting your ability to operate in California without interruption.
We serve Culver City and the surrounding Los Angeles County area with CARB-certified emissions testing for heavy-duty diesel and alternative fuel trucks. Our entire crew has completed California Air Resources Board certification—not because it sounds good, but because it’s the only way to legally perform Clean Truck Check testing.
Culver City sits right in the heart of California’s strictest air quality enforcement zone. If you operate here, you know CARB regulations aren’t suggestions. They’re requirements with real financial consequences.
We’ve built our service around the reality that fleet owners and owner-operators don’t have time for three-hour manual inspections or confusing compliance portals. You need testing done right, done fast, and submitted correctly the first time. That’s what we do.
If your truck is a 2013 or newer model with OBD (on-board diagnostics), the testing process is straightforward. We connect a CARB-certified OBD device to your truck’s system and scan the engine’s emissions data. The test itself is relatively fast—especially compared to older manual inspection methods that could take one to three hours per vehicle.
Once the scan is complete, we transmit your results directly to CARB’s CTC-VIS portal electronically. You receive documentation immediately for your records. No waiting. No mailing forms. No wondering if the state actually received your compliance proof.
Here’s what you need to know: California requires most heavy-duty vehicles to test every six months. If your truck gets flagged with a Notice to Submit to Testing, you have 30 calendar days to submit a passing test. Miss that window and you’re facing penalties and potential registration holds.
We also help with CTC-VIS portal registration if you’re new to the program or need assistance setting up your account. The state’s system can be confusing, and mistakes delay compliance. We walk you through it so it’s done correctly from the start.

This service applies specifically 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 doesn’t meet both criteria, this isn’t the right test. We’re not being picky—California law defines exactly which vehicles require Clean Truck Check compliance, and we follow those rules precisely.
For qualifying trucks, you get a full OBD emissions scan using CARB-approved equipment, electronic submission of results to the state, and immediate documentation proving compliance. If you’re operating in or through California—even if your truck is registered out of state—you’re subject to these requirements.
Culver City’s location means you’re likely running routes through some of California’s most heavily monitored corridors. CARB enforcement isn’t theoretical here. It’s active, and non-compliance gets caught. The program is designed to identify high-emitting vehicles and pull them off the road until they’re fixed and retested.
Starting in 2027, testing frequency increases to four times per year for OBD-equipped vehicles. That’s not far off. Getting your compliance process dialed in now means you’re ready when the requirements tighten.
Yes, if it operates on California public roads. CARB’s Clean Truck Check program applies to all heavy-duty vehicles over 14,000 lbs GVWR that drive in California, regardless of where they’re registered. That includes out-of-state trucks, even if you’re just passing through on interstate routes.
California doesn’t care where your plates are from. If your truck uses California highways, it needs to comply with California emissions standards. That means registration with the CTC-VIS portal, payment of annual compliance fees, and passing emissions tests every six months.
Out-of-state operators sometimes assume they’re exempt. They’re not. CARB enforcement targets non-compliant vehicles at weigh stations, inspection points, and through automated monitoring systems. Getting pulled over and cited for non-compliance costs you time, money, and potentially your ability to complete that delivery.
Most heavy-duty vehicles currently require testing every six months. If your truck is California-registered, your compliance deadlines are tied to your DMV registration expiration date. Out-of-state trucks follow a different schedule based on when you first register with the Clean Truck Check program.
There’s a change coming. Starting in October 2027, OBD-equipped vehicles will need testing four times per year instead of twice. That’s a significant increase, and it means more frequent appointments and tighter compliance windows.
You’ll also receive a Notice to Submit to Testing if CARB’s system flags your truck as a potential high emitter. When that happens, you have 30 calendar days to get tested and submit passing results. Missing that deadline triggers penalties and can result in registration holds that prevent you from renewing your California registration or operating legally in the state.
If your truck fails, you need to get it repaired and retested. CARB’s program is specifically designed to catch vehicles with malfunctioning emissions control equipment and require timely repairs. A failed test means something in your emissions system isn’t working correctly—and you can’t legally operate that truck in California until it’s fixed.
The financial impact adds up fast. You’re paying for diagnostics, repairs, and retesting. Your truck is out of service, which means lost revenue for every day it’s not running. If you’re under a compliance deadline from a Notice to Submit to Testing, you’re also racing the clock to avoid penalties.
This is why regular maintenance matters. Catching emissions issues early—before they trigger a failed test or a notice from CARB—keeps your trucks on the road and your operation running smoothly. Waiting until you’re forced to test often means discovering problems at the worst possible time.
No. Our CARB compliance testing service is only for trucks that are model year 2013 or newer with OBD systems. If your truck is older than 2013, it doesn’t qualify for OBD testing under the Clean Truck Check program—it would require a different type of inspection that we don’t currently offer.
California’s program splits testing requirements by model year. Newer trucks with on-board diagnostics get OBD scans. Older trucks without OBD systems require manual inspections that take significantly longer and use different equipment. The two processes aren’t interchangeable.
If you’re running a mixed fleet with both older and newer trucks, you’ll need different testing providers for different vehicles. It’s frustrating, but that’s how CARB structured the program. Make sure you’re clear on which trucks need which type of test, because showing up for the wrong service wastes your time and doesn’t get you compliant.
You’re paying for three things: the annual compliance fee to CARB, the cost of each emissions test, and the operational impact of testing downtime. CARB’s annual fee varies by vehicle type and weight class—you pay that directly to the state through the CTC-VIS portal.
Testing costs depend on your provider, but the bigger expense is often the downtime. Traditional manual inspections for older trucks can take one to three hours per vehicle, which translates to $300 to $900 in lost productivity per truck. OBD testing for 2013+ trucks is faster, which reduces that hit.
Then there’s the cost of non-compliance. Fines run up to $1,000 per day per vehicle if you’re operating without valid compliance. Shippers who hire non-compliant carriers face penalties up to $10,000 per year per carrier. Registration holds prevent you from renewing tags, which means your truck can’t legally operate at all. The cost of staying compliant is real, but the cost of ignoring it is significantly higher.
Yes. CARB’s Clean Truck Check Vehicle Inspection System (CTC-VIS) is where you register your vehicles, pay annual compliance fees, and track your testing history. You need an active account before your test results can be properly submitted and recorded.
The portal isn’t the most intuitive system, and mistakes during registration can delay your compliance status. You need accurate VIN information, vehicle details, and proper account setup. If something’s entered incorrectly, your test results might not link to the right vehicle, which means the state doesn’t recognize you as compliant—even though you did the test.
We provide free assistance with CTC-VIS registration. We help you get your account set up correctly so your test results go where they need to go and your compliance status updates properly. It’s not glamorous work, but it prevents the kind of administrative headaches that turn into bigger problems when CARB comes asking for proof of compliance.
