You’ve got trucks to move and deadlines to hit. The last thing you need is a registration hold because your CARB compliance lapsed or a $10,000-per-day fine showing up in the mail.
California’s Heavy-Duty Inspection and Maintenance program isn’t optional. If you’re running 2013 or newer diesel trucks over 14,000 pounds GVWR in Huntington Park, CA, you’re required to complete semi-annual Clean Truck Check testing with a CARB credentialed tester. Miss a deadline and the DMV can freeze your registration. Fail an inspection without follow-up and penalties stack fast.
We handle CARB certified smog checks on-site at your yard, shop, or wherever your fleet is parked. You schedule the test, we show up with CARB-approved OBD equipment, run the inspection, and transmit results electronically to the state the same day. You get a copy for your records. Your trucks stay in service. Your compliance stays current.
No waiting at a test station. No pulling trucks off routes. Just fast, certified CARB emissions testing that fits your schedule and keeps you legal.

Huntington Park has one of the densest concentrations of commercial trucking operations in Southern California. We built this service specifically for owner-operators and small fleets who can’t afford downtime but can’t risk penalties either. You need testing done right, done fast, and done without the hassle. That’s what we do.
First, you tell us which trucks need testing and where they’re located in Huntington Park, CA. We’ll confirm eligibility—remember, this service applies only to model year 2013 or newer diesel trucks with a GVWR over 14,000 pounds. Older trucks or lighter vehicles aren’t part of the CARB HD I/M program.
Once scheduled, we come to you. Our mobile unit is equipped with CARB-certified OBD diagnostic tools that connect directly to your truck’s onboard system. For 2013+ diesel engines, OBD testing is relatively fast—usually under 30 minutes per vehicle. We check for emissions control system faults, verify proper operation, and document results in real time.
If your truck passes, we transmit the compliance report electronically to CARB that same day. You receive a copy for your records, and your testing requirement is satisfied. If there’s a fault code or failure, we’ll walk you through what needs repair and help you understand next steps to get back in compliance within the 30-day window.
We also track your testing schedule so you’re not guessing when the next check is due. You’ll get reminders before deadlines, and we’ll coordinate follow-up tests as needed. The goal is to keep your operation moving without surprises.

Every Clean Truck Check we perform includes a full OBD scan using CARB-approved diagnostic equipment, electronic transmission of test results directly to the California Air Resources Board, and a compliance report delivered to you the same day. You also get documentation that satisfies DMV and CARB record-keeping requirements.
We’re available 24/7 because we know your trucks don’t run on a 9-to-5 schedule. Whether you need early morning testing before a haul or late-night service between shifts, we’ll work around your operation. All testing is conducted by CARB credentialed inspectors who’ve passed state certification and maintain active credentials with the Heavy-Duty Vehicle Inspection Program.
In Huntington Park, CA, where freight and logistics drive the local economy, staying CARB compliant isn’t just about avoiding fines—it’s about protecting your ability to operate. CARB collected over $21 million in penalties in 2022 alone, and enforcement is only getting stricter. Roadside monitoring devices can flag high-emitting vehicles between test intervals, triggering mandatory follow-up inspections within 30 days.
We also provide compliance consultation if you’re dealing with penalty notices or registration holds. We’ve successfully helped clients negotiate reduced fines and navigate CARB’s appeals process. If you’re behind on testing or facing enforcement action, we can help you get current and avoid escalation.
Only if it meets specific criteria. California’s Heavy-Duty Inspection and Maintenance program applies to diesel and alternative fuel trucks with a gross vehicle weight rating over 14,000 pounds that are model year 2013 or newer.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, it’s not subject to CARB Clean Truck Check requirements. But if you’re running newer heavy-duty diesel equipment in Huntington Park, CA, you’re required to complete emissions testing every six months and pay an annual $30 compliance fee per vehicle.
The testing must be performed by a CARB credentialed tester using approved OBD diagnostic equipment. Results get transmitted electronically to the state, and you need to keep records of every test. Missing a deadline can trigger DMV registration holds, and operating a non-compliant truck can result in fines up to $10,000 per vehicle per day.
Most heavy-duty diesel trucks in the CARB compliance program require testing every six months. The semi-annual schedule applies to vehicles with 2013 or newer diesel engines and a GVWR over 14,000 pounds operating in California.
Your testing deadline is based on your vehicle’s registration and previous test date. CARB tracks compliance electronically, so if you miss a window, the system flags it automatically. That can lead to a registration hold from the DMV, which means your truck can’t legally operate until you’re back in compliance.
We help fleet operators in Huntington Park, CA stay on schedule by tracking test dates and sending reminders before deadlines. If you’re managing multiple trucks, we can coordinate all your testing in a single visit to your location. That way you’re not juggling dates or risking a missed inspection because one truck was out on a long haul.
You’ll have 30 days to make repairs and retest. A failure means the OBD system detected a fault in your emissions control equipment—usually a sensor issue, DPF problem, or EGR system malfunction.
We provide a detailed report showing which fault codes triggered the failure. You’ll need to take your truck to a qualified diesel mechanic to diagnose and repair the issue. Once repairs are complete, you schedule a retest with a CARB credentialed tester to confirm the problem is fixed.
If you don’t retest within 30 days, CARB can issue penalties and the DMV may place a hold on your registration. In Huntington Park, CA, where your trucks are your livelihood, that’s not a risk worth taking. We work with several local diesel shops and can point you toward reliable repair options if you need them. Our goal is to get you back in compliance as quickly as possible so your business doesn’t suffer.
Yes. We’re a fully mobile CARB emissions testing service, which means we bring the equipment to your yard, warehouse, or job site anywhere in Huntington Park, CA.
You don’t need to pull your trucks off the road and drive them to a testing station. We schedule a time that works for your operation, show up with CARB-certified OBD diagnostic tools, and complete the inspection on-site. Testing for 2013+ diesel trucks is relatively fast—usually under 30 minutes per vehicle.
We’re available 24/7 because we know trucking doesn’t stop at 5 p.m. Whether you need early morning testing before your drivers head out or late-night service between shifts, we’ll accommodate your schedule. After testing, we transmit results electronically to CARB the same day and provide you with a compliance report for your records. Mobile service means less downtime, less hassle, and no disruption to your daily operations.
Testing costs vary depending on your fleet size and location, but the state also requires an annual $30 compliance fee per vehicle. That fee goes directly to CARB and covers your participation in the Heavy-Duty Inspection and Maintenance program.
Our mobile testing service is priced to be competitive with stationary test stations, but you’re also saving time and money by not having to take trucks out of service to drive to a facility. When you factor in driver wages, fuel, and lost productivity, on-site testing in Huntington Park, CA usually costs less overall.
We provide upfront pricing with no hidden fees. If you’re managing a fleet, we can offer volume pricing for multiple trucks tested in a single visit. And if you’re facing penalties or registration holds due to missed testing, we can help you get current and avoid further fines. The cost of staying compliant is always lower than the cost of penalties—CARB fines can reach $10,000 per vehicle per day, and some violations go as high as $75,000 per day.
You’ll receive a compliance report that includes your test results, vehicle identification details, and confirmation that results were transmitted electronically to CARB. This documentation satisfies state record-keeping requirements and serves as proof of compliance if you’re ever audited or stopped at a roadside inspection.
CARB requires fleet operators to maintain records of all emissions testing, and you’re responsible for keeping those records accessible. We provide both digital and printed copies so you can file them however works best for your operation.
If your truck passes, the report confirms your compliance status and shows your next testing deadline. If there’s a failure, the report includes fault codes and details about what needs repair. In Huntington Park, CA, where CARB enforcement is active and penalties are steep, having clear documentation is critical. We make sure you’re covered with everything you need to prove compliance and avoid unnecessary fines or registration issues.
