You need your truck on the road, not sitting in a yard waiting for paperwork. CARB diesel compliance isn’t optional anymore—it’s enforced with roadside sensors, automated plate readers, and penalties that start at $10,000 per vehicle and climb fast.
If your truck is model year 2013 or newer and weighs over 14,000 pounds, California requires Clean Truck Check emissions testing. Miss your deadline and the DMV blocks your registration. Fail a roadside flag and you’ve got 30 days to submit proof or face escalating fines.
We handle CARB emissions testing for qualifying heavy-duty trucks right here in Huntington Park. You get your compliance certificate, your truck stays legal, and you keep access to the ports, rail yards, and freight facilities that keep your business moving. No drama, no downtime you can’t afford.
We operate in the heart of LA County’s trucking corridor, where thousands of drivers move freight through some of the busiest logistics hubs in the country. We’re not trying to be everything to everyone—we focus on what matters for heavy-duty operators in Huntington Park and the surrounding area.
Huntington Park has over 2,500 truck drivers working locally. That means you’re not alone in dealing with California’s emissions rules, and it means we see the same challenges you do every day. Our team knows the Clean Truck Check requirements, the testing timelines, and what it takes to keep your fleet compliant without burning through your operating budget.
We’re set up to handle 2013 and newer trucks over 14,000 pounds GVWR. If your vehicle qualifies, we can test it, certify it, and get you back on the road.
You bring your truck to our facility in Huntington Park. We verify that it’s a 2013 or newer model year and over 14,000 pounds—those are the vehicles covered under the Clean Truck Check program. If it doesn’t meet those specs, we’ll let you know upfront.
Once confirmed, we run the CARB emissions testing using certified equipment. The test measures your truck’s emissions output to ensure it meets California’s heavy-duty vehicle compliance standards. Most tests are completed the same day, depending on volume.
After your truck passes, we submit the results directly to CARB’s CTC-VIS system and provide you with your compliance certificate. That certificate is what keeps your registration active and proves compliance during roadside inspections or facility access checks. You’ll also need to pay the $31.18 annual compliance fee, which we can walk you through.
If your truck doesn’t pass, we’ll explain what flagged and what your options are. Some issues require mechanical repairs before retesting. We don’t do the repairs ourselves, but we’ll point you in the right direction so you’re not guessing.

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, it’s not part of the Clean Truck Check program—yet. California’s regulations are phased, and right now, this is the qualifying range.
Testing frequency depends on your vehicle. Currently, qualifying trucks need testing twice per year, but that will increase to four times annually as the program expands. You’ll receive a compliance certificate after each passing test, and you’re required to submit results within 90 days of your applicable deadline.
CARB uses roadside monitoring devices throughout California to flag high-polluting vehicles. If your truck gets flagged, you’ll receive a Notice to Submit to Testing. That gives you 30 days to get compliant or face penalties. The system is automated, and enforcement is active—especially around ports, freight hubs, and major trucking routes through LA County.
In Huntington Park, where logistics and freight movement drive the local economy, staying compliant isn’t just about avoiding fines. It’s about maintaining access to the facilities and routes that keep your operation viable. One missed test can mean a registration hold, and that means your truck isn’t earning.
Your truck needs Clean Truck Check testing if it’s model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds. That’s the current threshold under California’s heavy-duty vehicle compliance program.
If your truck is older than 2013 or weighs less than 14,000 pounds, it’s not covered under this program right now. But California’s emissions rules are phased, so that could change. For now, the focus is on newer, heavier trucks operating in the state.
You’ll need to submit passing test results twice per year, and eventually four times per year as the program ramps up. If you operate in California or pass through regularly, this isn’t optional—it’s enforced with fines, registration holds, and facility access restrictions.
If you miss your testing deadline, the DMV will place a registration hold on your vehicle. That means you can’t renew your registration until you submit proof of compliance. Your truck is effectively grounded until you get tested and pass.
CARB also uses roadside sensors and automated license plate readers to identify non-compliant vehicles. If your truck gets flagged, you’ll receive a Notice to Submit to Testing. You have 30 days to comply. If you don’t, fines start at $10,000 per vehicle and can climb to $75,000 per day depending on the violation.
Beyond fines, you lose access to California ports, rail yards, and freight facilities. For operators in Huntington Park and LA County, that’s a business killer. The enforcement is real, and it’s automated—so waiting it out isn’t a strategy.
Most CARB emissions testing for heavy-duty trucks is completed the same day. The actual test doesn’t take long—it’s the verification, equipment setup, and results submission that add time. If we’re busy, there may be a short wait, but we move trucks through as quickly as we can.
Once your truck passes, we submit the results directly to CARB’s system and provide your compliance certificate on the spot. You’re good to go as soon as that’s done.
If your truck doesn’t pass, you’ll need to address whatever caused the failure before retesting. That could mean mechanical repairs, which we don’t handle in-house. Depending on the issue, that could add days or weeks to your timeline—so it’s worth staying on top of your testing schedule instead of waiting until the last minute.
You can get tested at any CARB-certified facility in California. It doesn’t have to be in Huntington Park. But if you’re operating locally or passing through LA County, coming to a facility near your route saves time and keeps your truck moving.
We’re located in Huntington Park, which puts us right in the middle of the LA trucking corridor. That makes us convenient for drivers working the ports, freight yards, and distribution centers in the area. You’re not adding miles or downtime just to stay compliant.
The key is making sure the facility you choose is certified to perform Clean Truck Check testing for vehicles over 14,000 pounds. Not every smog shop handles heavy-duty trucks, so confirm before you show up. We specialize in 2013 and newer trucks in that weight class, so if your vehicle qualifies, we’re set up for it.
The $31.18 fee is an annual charge required by CARB for participation in the Clean Truck Check program. It’s separate from the cost of testing. You pay it once per year, per vehicle, and it goes directly to the state—not to the testing facility.
This fee keeps your vehicle registered in CARB’s compliance system. Without it, you’re flagged as non-compliant even if you’ve passed your emissions test. It’s a small cost compared to the fines and registration holds you’ll face if you skip it.
We can walk you through the payment process when you come in for testing. It’s straightforward, but it’s easy to overlook if you’re not familiar with the program. Make sure it’s paid on time, or you’ll end up dealing with penalties that are way more expensive than thirty bucks.
If your truck fails, we’ll explain what caused the failure and what your next steps are. Most failures are tied to mechanical issues—faulty sensors, exhaust system problems, or emissions control components that aren’t working correctly.
We don’t perform mechanical repairs, so you’ll need to take your truck to a qualified diesel mechanic to address the issue. Once the repairs are done, you’ll need to come back for a retest. You can’t submit a passing result until your truck actually passes, and the clock is still ticking on your compliance deadline.
Some operators try to push through with a failing truck, hoping it’ll pass on a second attempt without repairs. That’s a gamble that usually costs more in the long run. If you’re flagged by CARB or hit a registration deadline, you’re looking at fines and downtime that far exceed the cost of fixing the problem. Get it handled, get retested, and get back to work.
