When your truck is compliant, you’re not thinking about CARB. You’re not watching your registration deadline, not worried about a DMV hold blocking your renewal, and not scrambling to find a credentialed tester before a 30-day Notice to Submit window runs out. That’s the version of this you want and it’s more achievable than most operators realize.
For contractors working the Peninsula hauling equipment for landslide remediation projects in Portuguese Bend, running supplies to job sites in Lunada Bay, or servicing the luxury residential builds throughout Miraleste the compliance clock doesn’t care about your project schedule. But with mobile testing, you don’t have to choose between the job and the test. We come to where your truck is parked, run the OBD test on-site, and submit the results directly to CARB’s CTC-VIS database before we leave.
Vendors and suppliers making regular deliveries to Terranea Resort or Trump National Golf Club face the same reality. Those routes end on the Peninsula and the nearest fixed-location testing facility is in Torrance, which means navigating back out through Hawthorne Boulevard just to come back. Mobile testing eliminates that entirely. One less thing pulling your truck off the road.
We do one thing: Clean Truck Check OBD emissions testing for heavy-duty trucks model year 2013 or newer with a GVWR over 14,000 pounds. Not passenger cars. Not older opacity-test vehicles. Not general smog checks. Just the specific trucks that CARB’s HD I/M program requires to test and nothing else.
That focus matters because not every tester operating in Los Angeles County holds legitimate CARB credentials or uses CARB-certified OBD equipment. An invalid test from an uncredentialed tester leaves your truck non-compliant even if you paid for the service. We’re publicly listed on CARB’s official credentialed tester registry at arb.ca.gov you can verify it yourself before booking anything.
We serve Los Angeles County, which includes Rancho Palos Verdes, the full Palos Verdes Peninsula, and the surrounding South Bay communities where many of the operators who work in this area are based. If your truck is on the Peninsula or nearby, we can get to it.
It starts with a quick booking. You tell us where the truck is located a job site in Rancho Palos Verdes, a yard in the South Bay, a staging area near the Eastview neighborhood off Western Avenue and we schedule a time that works around your operation. No need to reposition the vehicle to a shop. No driving it out of the Peninsula and back.
When we arrive, we connect a CARB-certified OBD test device to your truck’s diagnostic port. The device reads the emissions data directly from the truck’s onboard system this is the same data CARB requires under the Clean Truck Check program for 2013 and newer diesel and alternative fuel heavy-duty vehicles. The test itself typically takes under 30 minutes. If the truck passes, results go directly into CARB’s CTC-VIS database from our equipment electronically, immediately, no manual upload required on your end.
After submission, CARB transmits updated compliance data to the DMV nightly. Within 3 to 5 business days, your truck’s record reflects the passing test. If you had a registration hold, it clears on that timeline. You can verify your own compliance status in your CTC-VIS account at any point. From booking to confirmed compliance, the whole process is straightforward and your truck never had to leave the job site.

The Clean Truck Check formally CARB’s Heavy-Duty Inspection and Maintenance program applies to trucks that are model year 2013 or newer with a Gross Vehicle Weight Rating over 14,000 pounds. If your truck is older than 2013 or under that weight threshold, this program does not apply to you. For trucks that do qualify, the requirement is currently semi-annual two tests per year. Starting October 1, 2027, that shifts to quarterly, meaning four tests per year for OBD-equipped vehicles.
The annual CARB compliance fee is $31.18 per vehicle but paying that fee does not satisfy the emissions testing requirement. These are two separate obligations, and this is the most common compliance mistake happening right now across the South Bay. Operators who paid the fee and assumed they were done are discovering registration holds at renewal time. The test has to happen and be submitted to CTC-VIS separately.
For operators working in and around Rancho Palos Verdes whether you’re a contractor on a Peninsula infrastructure project, a delivery driver making runs to Terranea Resort, or a drayage operator working the South Bay corridor near the Port of Los Angeles in adjacent San Pedro the compliance requirement is the same regardless of where your truck is parked. We use only CARB-certified OBD equipment bearing valid CARB Executive Orders. Every test we perform is submitted directly and electronically to CTC-VIS. No paperwork on your end. No portal navigation. Just a compliant truck.
It depends on two things: the model year and the GVWR. If your truck is model year 2013 or newer and has a Gross Vehicle Weight Rating over 14,000 pounds, it falls under CARB’s Clean Truck Check program regardless of what it hauls or where it operates. The program applies statewide, so whether you’re making deliveries to Terranea Resort on Palos Verdes Drive South, running supplies to a construction site in Portuguese Bend, or operating anywhere else in Los Angeles County, the requirement follows the truck.
If your truck is older than 2013 or under the 14,000-pound GVWR threshold, this specific program does not apply. Lighter vehicles and older trucks are subject to different CARB regulations. If you’re not sure where your truck falls, the GVWR is listed on the door jamb placard, and the model year is on the registration. Those two numbers tell you everything you need to know about whether a Clean Truck Check is required.
No and this is the most important thing to understand about the Clean Truck Check program right now. The annual CARB compliance fee ($31.18 per vehicle in 2025) and the OBD emissions test are two completely separate requirements. Paying the fee registers your vehicle in the system. It does not substitute for the actual test.
Trucks that have paid the fee but never submitted a passing OBD test are non-compliant in CARB’s records. CARB transmits that compliance data to the DMV nightly, which means those trucks will hit a registration hold at renewal time even if the owner has been paying the fee every year. This has caught a lot of South Bay operators off guard since enforcement began in October 2024. If you’re not certain whether a passing test has been submitted for your truck in CTC-VIS, the safest move is to log into your account and check or book a test and remove the uncertainty entirely.
A Notice to Submit to Testing means CARB has flagged your vehicle as non-compliant and you have 30 calendar days to submit a passing test. That window goes fast especially if the tester you’re trying to reach operates out of a fixed location with limited hours. The nearest fixed-location Clean Truck Check facility to Rancho Palos Verdes is in Torrance, which is closed on weekends. For an operator working on the Peninsula, that’s a real constraint.
Mobile testing is the practical answer here. We can come to your truck’s location on the Peninsula, in the South Bay, wherever the vehicle is staged and get the test done and submitted to CTC-VIS before your deadline. After submission, CARB updates DMV records within 3 to 5 business days. If you’ve received an NST notice, don’t wait on it. The 30-day window is firm, and enforcement consequences include fines of up to $10,000 per vehicle per day and potential removal from service.
Right now, OBD-equipped vehicles which covers 2013 and newer diesel and alternative fuel heavy-duty trucks are required to test semi-annually, meaning twice per year. That requirement has been in effect since October 1, 2024, with the first compliance deadline landing on January 1, 2025.
Starting October 1, 2027, the frequency increases to quarterly four tests per year. For fleet managers and owner-operators working in and around Rancho Palos Verdes, that’s a significant change worth planning for now. Contractors running multiple trucks on Peninsula projects, suppliers making regular runs to the South Bay’s hospitality venues, and drayage operators working the corridor near the Port of Los Angeles will all feel that shift. Establishing a reliable testing relationship with us before 2027 means the transition is a scheduled calendar item not a last-minute scramble every three months.
Yes that’s exactly how we operate. There are no freeways within Rancho Palos Verdes city limits. Every route off the Peninsula runs through surface roads: Hawthorne Boulevard north toward Torrance, Crenshaw Boulevard toward the I-405, or Western Avenue east toward San Pedro and the I-110. For a heavy-duty commercial vehicle, that’s a meaningful amount of time and fuel just to reach a testing facility and then you have to come back.
Mobile testing means we come to wherever your truck is located a job site in Lunada Bay, a staging area near the Eastview neighborhood, a contractor yard in the South Bay. You tell us where the vehicle is, we schedule around your operation, and the test happens on-site. Results go directly to CARB’s CTC-VIS system from our equipment. The truck doesn’t move, your crew doesn’t stop, and the compliance gets handled.
Once we submit your passing test directly to CARB’s CTC-VIS database, CARB sends updated compliance data to the DMV on a nightly transmission cycle. In most cases, your truck’s record reflects the passing test within 3 to 5 business days. If you had a registration hold in place, it clears on that same timeline you don’t need to call the DMV or submit anything separately.
You can also verify your own compliance status at any point by logging into your CTC-VIS account at CARB’s website. That’s the most direct way to confirm your truck’s record before a registration renewal comes up. For operators in Rancho Palos Verdes and the surrounding South Bay who discovered a hold at renewal time a common scenario given how recently full enforcement began this timeline means the problem is typically resolved within a normal business week once a passing test is on file.
