You’re running a tight operation. Your trucks need to be on the road, not sitting at a testing station or stuck in DMV limbo because someone missed a compliance deadline.
California’s Clean Truck Check program isn’t optional anymore. If you’re operating heavy-duty trucks—model year 2013 or newer with a GVWR over 14,000 pounds—you’re required to test and report to CARB. Miss it, and you’re looking at registration holds that take your trucks out of service. That’s lost revenue, missed deliveries, and a headache you don’t need.
We handle the testing at your location. You schedule it, we show up with CARB-certified equipment, run the OBD emissions test, and submit results directly to the state database. You get confirmation the same day. No driving across town. No waiting in line. No wondering if it’s done right.
This is about keeping your operation moving without the compliance stress.
We’re a licensed HD/IM tester with CARB certification and over 15 years of experience in California emissions compliance. We’re not a general smog shop trying to figure out heavy-duty regulations on the fly. We specialize in 2013 and newer trucks that fall under Clean Truck Check requirements.
Florence-Graham sits in the heart of LA County’s industrial corridor. Transportation and warehousing employ thousands of people here, and we know the trucks that keep this area running. We’ve built our service around what fleet operators and owner-operators actually need: fast, accurate testing that doesn’t disrupt your day.
You’re dealing with enough—fuel costs, driver schedules, maintenance windows. CARB compliance shouldn’t be another thing eating up your time. That’s where we come in.
First, you reach out and schedule a time that works for your operation. We offer same-day appointments for most locations in LA County, including Florence-Graham. You tell us where your truck is, and we bring the testing equipment to you.
When we arrive, we connect to your truck’s OBD system using CARB-approved diagnostic tools. For 2013 and newer diesel engines, this is a computerized test that checks emission control systems and monitors performance data. It typically takes 15 to 30 minutes per vehicle, depending on the truck. You don’t need to pull it off a job site or drive it somewhere—we work around your schedule.
Once testing is complete, we submit the results directly to CARB’s database through the CTC-VIS system. You’ll receive confirmation that your truck is compliant and your $31.18 annual compliance fee has been processed. If there’s an issue, we’ll walk you through what needs to happen next—no surprises, no runaround.
For fleets with multiple trucks, we offer discounted pricing and can schedule bulk testing to get everything handled in one visit. The goal is simple: get you compliant, keep your trucks registered, and let you get back to work.

This service applies only to trucks that are model year 2013 or newer and have a GVWR over 14,000 pounds. If your truck doesn’t meet both of those criteria, this isn’t the right testing program. Older trucks or lighter vehicles fall under different regulations, and we want to be clear about that upfront so you’re not wasting time.
For qualifying trucks, you’re required to test at least twice a year right now. By 2027, that increases to quarterly. CARB monitors compliance through roadside inspections, border checks, and remote emissions devices at ports and railyards. If your truck gets flagged, you have 30 days to test and report. If you don’t, the DMV won’t renew your registration.
Florence-Graham’s location near major freight routes and industrial zones means your trucks are likely passing through high-enforcement areas regularly. CARB isn’t messing around with this program—it’s tied to $75 billion in projected health benefits and stricter air quality goals. The penalties for non-compliance start at registration holds, but they can escalate to $10,000 per vehicle per day if violations continue.
We also help if you’ve already been flagged or received a notice. We can test quickly, submit results, and in some cases, work with you to address penalties or compliance issues. The earlier you handle it, the fewer problems you’ll face down the road.
You’re required to test if your truck is model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds. This applies to any heavy-duty truck operating in California, whether you’re based here or just passing through.
The program is called Clean Truck Check, and it started in 2023. CARB uses roadside monitoring and remote sensors to flag high-emitting vehicles. If your truck gets flagged, you have 30 days to complete testing and submit results, or your registration renewal gets blocked by the DMV.
Right now, testing is required at least twice a year. Starting in 2027, it moves to quarterly. The testing itself is OBD-based, meaning we plug into your truck’s onboard diagnostic system and check emission control performance. It’s not a visual inspection or tailpipe test—it’s all electronic data pulled directly from your engine’s computer.
Testing costs vary depending on whether you’re bringing one truck or scheduling a fleet. The state charges a $31.18 annual compliance fee per vehicle, which we process as part of the service. Our testing fee covers the mobile visit, OBD diagnostics, and submission of results to CARB’s database.
For fleets, we offer discounted pricing because we can test multiple trucks in one visit. That saves you time and keeps costs down compared to scheduling each truck separately. If you’re an owner-operator with one or two trucks, we still come to you—no need to drive to a testing station and lose half a day.
What’s included: CARB-certified equipment, a licensed HD/IM tester, same-day reporting to the state, and confirmation that your truck is compliant. If something fails, we’ll explain what’s wrong and what your options are. We don’t do repairs, but we can point you in the right direction and retest once the issue is fixed.
If your truck fails, it means the OBD system detected an issue with your emission controls—could be a sensor malfunction, a DPF problem, or something else triggering a fault code. You’ll need to get the issue repaired before you can pass and report compliance to CARB.
We’ll give you a detailed breakdown of what failed so you can take it to your mechanic with actual information, not just a vague “it didn’t pass.” Once repairs are done, we can come back and retest. You’re not stuck guessing or making multiple trips to a shop.
Here’s the important part: if you’ve been flagged by CARB and you’re in that 30-day window, the clock is still ticking. Get the repairs done as quickly as possible and schedule a retest. If you miss the deadline, the DMV puts a hold on your registration, and your truck can’t legally operate until you’re compliant. That’s lost income and potential penalties. The faster you address it, the less it costs you.
No. This service is specifically for Clean Truck Check, which only applies to model year 2013 and newer trucks with a GVWR over 14,000 pounds. If your truck is older or lighter, it falls under different California smog check requirements, and we’re not the right fit.
The reason for the 2013 cutoff is that’s when OBD systems became standard on heavy-duty diesel engines. Clean Truck Check relies on pulling data directly from the truck’s computer, so older trucks without that technology aren’t part of this program. They may still need testing, but it’s a different process with different rules.
If you’re not sure whether your truck qualifies, check the model year and GVWR on your registration. Both have to meet the criteria. If you’re running a mixed fleet with some older trucks, we can handle the 2013+ vehicles, but you’ll need to find a different provider for anything older.
Yes. We bring the testing equipment to your location—whether that’s a yard, a job site, or wherever your truck is parked in Florence-Graham or the surrounding LA County area. That’s the whole point of mobile service: you don’t lose time driving to a testing station.
We offer same-day appointments for most locations, depending on schedule availability. If you’ve got multiple trucks, we can test them all in one visit. For fleets, that’s a huge time-saver compared to pulling trucks off the road one by one.
Florence-Graham is right in our service area, and we’re familiar with the industrial zones, freight routes, and truck operations around here. We know you’re busy, and we’re not going to waste your time. You schedule it, we show up, we test, we report to CARB. You get confirmation the same day, and your trucks stay compliant without the hassle.
Right now, you’re required to test at least twice a year—every six months. CARB is tightening that schedule, and by 2027, testing will be required quarterly. That means every three months, you’ll need to run an OBD test and report results to the state.
The testing frequency is tied to California’s air quality goals and the Clean Truck Check program’s enforcement timeline. CARB is serious about reducing emissions from heavy-duty trucks, and they’re using this program to monitor compliance in real time. If you skip a test or miss a deadline, the DMV gets notified and your registration renewal gets blocked.
You’ll also need to test if your truck gets flagged during a roadside inspection or by remote monitoring equipment. CARB uses sensors at ports, railyards, and border crossings to detect high emitters. If your truck triggers one of those, you have 30 days to test and submit results. Missing that deadline means your truck is out of service until you’re compliant. It’s easier to stay on schedule and avoid the stress.
