Your trucks stay on the road. That’s what matters.
When your heavy-duty vehicles pass their Clean Truck Check, you’re not just checking a box. You’re protecting your business from DMV registration holds that can ground your fleet overnight. You’re avoiding penalties that start at $10,000 per vehicle per day—fines that add up faster than most operators realize.
You’re also buying yourself six months of operational freedom. No surprise citations. No scrambling to find a tester when deadlines hit. Just proof of compliance uploaded directly to the CARB database, tied to your VIN, and recognized statewide.
For fleet operators in Lakewood and across Los Angeles County, that means fewer interruptions during peak logistics seasons. For owner-operators, it means you can focus on the next load instead of worrying whether your truck’s legal to drive. The test takes about 15 minutes. The peace of mind lasts until your next deadline.
This isn’t about passing a smog test. It’s about keeping your livelihood intact while California’s emissions regulations get stricter every year.
We focus exclusively on Clean Truck Check compliance for model year 2013 and newer heavy-duty vehicles. If your truck doesn’t meet those criteria, we’ll tell you upfront—we don’t waste your time.
Our testers are CARB-credentialed, which means they’ve completed the official training course, passed the exam with at least 80%, and maintain current certification. We use CARB-validated OBD test devices and submit results directly to the state database in real time.
We’re located in Lakewood, right in the middle of one of the busiest trucking corridors in Southern California. We know the operators running through Long Beach, the fleets staging out of Commerce, and the owner-operators trying to stay compliant without losing a day of work. This isn’t a side service for us. It’s what we do.
You bring your truck in. We verify it’s a 2013 or newer model with a GVWR over 14,000 pounds—that’s the only type of vehicle that qualifies for this program.
Our CARB-credentialed tester connects a validated OBD device to your truck’s diagnostic port. The system pulls data directly from your vehicle’s onboard computer—checking emissions performance, fault codes, and readiness monitors. This isn’t a visual inspection. It’s a data-driven compliance check that takes about 15 minutes from start to finish.
If your truck passes, we submit the results to CARB’s database immediately. You’ll get documentation showing your compliance status, and your next deadline will be set six months out. If there’s an issue—a fault code, a readiness monitor that hasn’t completed, or an emissions system problem—we’ll tell you exactly what needs attention before you can retest.
You don’t need an appointment for most tests, but if you’re running a fleet or need to schedule around delivery windows, call ahead. We’ll work with your schedule because we know downtime costs you money.

This service applies to nearly all diesel and alternative fuel heavy-duty vehicles operating in California with a GVWR over 14,000 pounds and a model year of 2013 or newer. That includes commercial trucks, government fleet vehicles, and out-of-state registered trucks operating in California.
Starting in 2025, compliance deadlines happen twice a year—every six months. Miss a deadline, and your vehicle gets flagged in the CARB database. That triggers a registration hold with the DMV, which means you can’t renew your tags until you pass. For out-of-state trucks, it can mean operational restrictions the next time you cross into California.
The annual compliance fee is $31.18 per vehicle as of 2025, separate from the testing fee. That’s a CARB charge, not ours. But compared to the $10,000-per-day penalties for non-compliance, it’s a small price to keep your trucks legal.
Lakewood’s location near the ports and major freight routes means heavy-duty vehicle compliance isn’t optional here—it’s enforced. CARB estimates this program will prevent 7,500 air quality-related deaths by 2050, which is why the state takes violations seriously. You’re not just avoiding fines. You’re operating in one of the most regulated trucking markets in the country, and this test is your proof you’re doing it right.
Your truck qualifies if it’s model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds. That’s it. Those are the only two criteria.
If your truck is older than 2013, it doesn’t qualify for this program—you’d need a different type of emissions test, and we’d point you in the right direction. If it’s under 14,000 pounds GVWR, same thing. This program was designed specifically for newer heavy-duty trucks, so the requirements are narrow.
Most Class 7 and Class 8 commercial trucks fall into this category. So do many medium-duty trucks used in construction, delivery fleets, and municipal operations. If you’re not sure about your GVWR, check the certification label on the driver’s side door jamb—it’ll list the exact weight rating. If you’re still unsure, call us with your VIN and we’ll confirm eligibility before you drive over.
Starting in 2025, you’ll need a passing test every six months. Your specific deadline depends on your vehicle’s VIN and when your last test was completed.
CARB assigns two compliance deadlines per year for each vehicle. Miss one, and you’re flagged in the state database. That triggers a registration hold, which means your DMV renewal gets blocked until you pass a test and clear the violation.
The good news is that once you pass, your next deadline is automatically set six months out. You’ll get reminders from CARB if you’re registered in California, but if you’re an out-of-state operator, it’s on you to track your deadlines. We recommend setting a calendar alert for a week or two before your due date—that gives you a buffer in case your truck needs repairs before it can pass.
This isn’t like a regular smog check where you test once every two years. Heavy-duty emissions compliance is more frequent because these vehicles contribute disproportionately to air pollution in California. It’s stricter, but it’s also faster—15 minutes twice a year versus longer inspections for older programs.
You’ll get a detailed report showing exactly why it failed—usually a fault code, an incomplete readiness monitor, or an emissions system issue that needs repair.
The most common failure reasons are check engine lights that haven’t been addressed, diesel particulate filters that need service, or readiness monitors that haven’t completed their drive cycles yet. Sometimes it’s a simple fix. Sometimes it means taking your truck to a diesel mechanic before you can retest.
We don’t do repairs—we only test. But we’ll explain what the codes mean and what type of service you’re looking at. If it’s a readiness monitor issue, we can tell you what kind of driving conditions will help it complete. If it’s a fault code, you’ll need a qualified technician to diagnose and fix the problem before you come back.
You can retest as soon as the issue is resolved. There’s no waiting period. And if you’re up against a compliance deadline, get it handled fast—because once that deadline passes, you’re in violation and the penalties start adding up.
We can handle fleet testing, but it depends on how many trucks you’re bringing in and when you need them done.
If you’ve got three or four trucks, you can usually bring them in without an appointment and we’ll run them back to back. If you’re managing a larger fleet—ten, twenty, or more vehicles—call ahead so we can block out time and make sure we’re staffed appropriately. That way you’re not waiting around while we juggle walk-ins.
Some fleet operators prefer to stagger their tests throughout the compliance period to avoid having every truck due at the same time. That’s smart planning, especially if you’re running tight schedules and can’t afford to have multiple vehicles down simultaneously. We can work with you on a testing calendar that spreads out your deadlines and keeps your operation running smoothly.
For fleets operating out of Lakewood or nearby cities in LA County, we’re centrally located and easy to access. If you’ve got trucks coming back from the ports or staging in the area, we’re a convenient stop before they head out again.
Yes. If your truck is registered out of state but operates in California, you’re subject to the same Clean Truck Check requirements as California-registered vehicles.
CARB doesn’t care where your plates are from. If you’re driving a 2013 or newer heavy-duty truck in California, you need to comply. That means passing a test every six months and keeping your compliance status current in the CARB database.
The difference is that out-of-state operators don’t get automatic reminders from the DMV. You have to track your own deadlines. Miss one, and you risk getting pulled over and cited during a roadside inspection—or worse, having your truck restricted from operating in California until you get compliant.
A lot of interstate operators don’t realize how seriously California enforces this. The state has some of the strictest emissions regulations in the country, and heavy-duty trucks are a major focus. If you’re running loads into or through California regularly, build this test into your route planning. It’s faster and cheaper than dealing with a violation after the fact.
A Clean Truck Check is specifically for heavy-duty trucks model year 2013 and newer with a GVWR over 14,000 pounds. A regular smog check is for lighter vehicles—cars, SUVs, pickups under 14,000 pounds—and follows completely different testing procedures.
The Clean Truck Check uses OBD diagnostics to pull data directly from your truck’s emissions control systems. It’s faster and more focused than older inspection methods. There’s no tailpipe test, no visual inspection of components—just a data download that confirms your truck’s emissions systems are working as designed.
Regular smog checks, on the other hand, often involve tailpipe emissions testing, visual inspections, and different equipment. They’re also required on a different schedule—usually every two years for most passenger vehicles in California.
If you’re driving a semi truck, a heavy-duty delivery truck, or a commercial vehicle that meets the weight and year requirements, you need a Clean Truck Check. If you’re driving a pickup truck or van under 14,000 pounds GVWR, you need a standard smog test. They’re separate programs with separate rules, and you can’t substitute one for the other.
