Torrance isn’t a low-visibility city when it comes to CARB enforcement. CARB has an active air quality monitoring network running throughout Torrance fenceline sensors at the PBF refinery, community monitors at schools and parks, and block-by-block data collected through a direct partnership between CARB and the City of Torrance. That infrastructure exists because the city sits at the intersection of two of Southern California’s busiest freight corridors: the I-405 and the I-110. Trucks operating in this environment are not flying under the radar.
What that means for you is straightforward. If your truck is model year 2013 or newer with a GVWR over 14,000 pounds and it operates in California, it needs Clean Truck Check testing currently twice a year, and starting October 2027, four times a year. A missed test doesn’t just mean a fine. It can mean a DMV registration hold that stops your truck from renewing, or a CARB enforcement notice with a hard 30-day deadline to get compliant.
The good news is that getting tested doesn’t have to cost you a workday. We come to your Torrance location your fleet yard, your loading dock, wherever the truck sits so your drivers stay on schedule and your operation doesn’t skip a beat. The test gets submitted directly to CTC-VIS, your compliance record updates, and you move on.
We do one thing: Clean Truck Check OBD testing for heavy-duty trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. That’s the entire scope of our business. No passenger cars, no opacity testing on older diesels, no light-duty vehicles. Just the trucks that fall under CARB’s HD I/M program tested correctly, by a credentialed tester, using CARB-certified equipment, with results submitted directly to CTC-VIS.
That focus matters in Torrance, where the commercial fleet ranges from port drayage trucks running the I-110 to San Pedro, to logistics vehicles serving Toyota and Honda’s South Bay campuses, to contractors working the PBF refinery in North Torrance. These operators need a tester who understands the compliance environment they’re in not a generalist shop that handles heavy-duty testing as a side job. Our credentials are publicly listed on CARB’s website, which means you can verify them before you ever book.
It starts with a quick conversation. You share your truck’s VIN, model year, and location in Torrance whether that’s a fleet yard near the North Torrance industrial zone, a loading dock off Crenshaw Boulevard, or a corporate campus on the east side of the city. From there, a testing appointment gets scheduled around your operation, not the other way around.
On the day of the test, we come to you with CARB-certified OBD equipment the kind that holds a CARB Executive Order, which is the only equipment CARB will accept for official HD I/M compliance testing. Our tester connects directly to your truck’s OBD system through the J1939 or J1979 port, reads the ECU data, and runs the diagnostic scan. The whole process typically takes under 30 minutes per vehicle.
Once the test is complete, results are submitted electronically and directly to CARB’s CTC-VIS portal. You don’t log in, you don’t file paperwork, and you don’t chase down confirmation. CARB transmits the compliance data to DMV within a few business days, and your truck’s record reflects the passing test. If you’re working against a CARB Notice to Submit to Testing and have a 30-day deadline, that timeline matters and direct submission is the fastest way to close the gap.

Clean Truck Check testing through our service applies specifically to diesel and alternative fuel trucks that are model year 2013 or newer with a GVWR over 14,000 pounds. If your truck doesn’t meet both of those thresholds, it falls outside the scope of this program and outside the scope of what we test. That specificity is intentional. Every piece of our operation is built around this one category of vehicle and this one type of test.
What’s included in every test: a CARB-credentialed tester comes to your Torrance location, connects CARB-certified OBD equipment to your truck, reads the vehicle’s ECU data, and submits a complete test record directly to CTC-VIS. There are no paper forms for you to manage, no portal logins to figure out, and no risk of a submission error leaving your truck’s record incomplete. The $31.18 annual compliance fee that CARB charges separately does not substitute for the emissions test both are required, and both need to be current for your truck to be fully compliant.
For fleet operators in Torrance managing multiple vehicles whether you’re running logistics out of the Del Amo corridor, supporting operations at one of the city’s automotive campuses, or contracting at the PBF refinery we can coordinate multi-vehicle testing on a single visit. Testing can also be scheduled up to 90 days before your compliance deadline, which means you can plan around your maintenance cycles instead of scrambling when a deadline hits.
Yes and if you’re running port drayage routes out of Torrance, you’re already operating in one of the most compliance-scrutinized freight environments in California. The Port of Los Angeles in San Pedro is roughly 8 to 10 miles south of central Torrance via the I-110, and trucks running that corridor are visible to CARB enforcement activity on a regular basis.
The Clean Truck Check requirement is triggered by two things: your truck must be model year 2013 or newer, and it must have a GVWR over 14,000 pounds. If your truck meets both criteria and operates in California, it needs to test regardless of where it’s based or what routes it runs. Port drayage operators in Torrance are also subject to the Port Drayage Truck Registry, which already requires model year 2014 or newer vehicles, so most trucks in that category are squarely within Clean Truck Check’s scope. Getting tested by a CARB-credentialed tester with certified equipment is the only way to generate a result that CARB will accept and post to your compliance record.
This is one of the most common and costly misunderstandings in the program. The $31.18 annual compliance fee and the OBD emissions test are two completely separate requirements paying one does not satisfy the other. CARB requires both, and your truck is not considered compliant until a passing test result has been submitted to CTC-VIS and your vehicle record reflects it.
If you’ve paid the fee but haven’t tested, your truck is still non-compliant in CARB’s system. That means you’re still exposed to the same enforcement consequences: fines of up to $10,000 per vehicle per day, potential DMV registration holds, and the risk of receiving a Notice to Submit to Testing with a 30-day deadline. The fix is straightforward get the OBD test done by a CARB-credentialed tester using certified equipment, and make sure results are submitted directly to CTC-VIS. We handle that submission as part of every test, so there’s no gap between the test happening and your record being updated.
Right now, the requirement is semi-annual twice per calendar year. That’s been the enforcement standard since CARB’s full HD I/M testing phase launched on October 1, 2024. Starting October 1, 2027, that frequency increases to quarterly, meaning four tests per year for every qualifying vehicle.
For Torrance fleet operators managing multiple trucks, that shift is significant. A fleet of ten vehicles that currently requires twenty tests per year will require forty by 2027. Getting a reliable, mobile testing relationship in place now before the frequency doubles and demand spikes across Los Angeles County is the kind of planning that prevents a compliance crunch later. We serve Los Angeles County and can schedule coordinated multi-vehicle testing visits for Torrance-based fleets, so the increased frequency doesn’t turn into an operational headache when 2027 arrives.
A Notice to Submit to Testing is a CARB enforcement notice, not a reminder. You have 30 calendar days from the date on that notice to submit a passing test result to CTC-VIS. If that deadline passes without a compliant test on record, you’re looking at fines, registration consequences, and continued enforcement exposure.
The most important thing you can do right now is get a test scheduled with a CARB-credentialed tester who can come to your Torrance location and submit results directly. Driving a heavy-duty truck across Los Angeles County to a fixed testing facility through I-405 traffic, which is some of the worst congestion in the country burns time you don’t have when you’re working against a 30-day window. We’re mobile, come to you, and handle the CTC-VIS submission immediately after testing. If you’re in Torrance and you’re holding an NST, the clock is already running schedule as soon as possible.
Yes, and for most Torrance fleet operators, that’s exactly how testing works most efficiently. Rather than scheduling individual appointments for each vehicle and dealing with the logistics of moving trucks one at a time, we can coordinate a single visit to your Torrance yard and test multiple vehicles back to back.
This is particularly useful for operations running out of North Torrance’s industrial corridor, logistics companies near the eastern side of the city, or contractors supporting the PBF refinery who maintain a fleet of qualifying vehicles. The OBD test itself typically takes under 30 minutes per truck, so a fleet of five vehicles can realistically be tested in a single morning without disrupting your operation. Each vehicle’s results are submitted directly to CTC-VIS individually, so every truck gets its own compliant record. If you’re managing a fleet and want to get ahead of the 2027 quarterly testing increase, coordinating a multi-vehicle visit now is a practical way to build that rhythm into your compliance calendar.
CARB’s Clean Truck Check program applies based on where a vehicle operates, not just where it’s registered. If an out-of-state truck is operating in California and meets the program’s criteria model year 2013 or newer, GVWR over 14,000 pounds it is subject to the same testing requirements as a California-registered vehicle.
For Torrance specifically, this comes up most often with trucks that are based elsewhere but regularly run freight into the South Bay serving the Ports of Los Angeles and Long Beach, delivering to the automotive campuses on the west side of the city, or supporting supply chain operations along the I-405 corridor. If your truck is in California regularly, CARB considers it subject to compliance requirements regardless of its home state registration. The safest approach is to verify your specific situation against CARB’s program guidelines and, if your truck qualifies, get a test on record with a credentialed tester before enforcement catches up. We can test qualifying vehicles at your Torrance location and submit results directly to CTC-VIS, giving you a documented compliance record no matter where the truck is registered.
