Your truck sits, you lose money. It’s that simple.
If you’re running a 2013 or newer diesel truck over 14,000 pounds in California, you need passing Clean Truck Check results uploaded to CARB’s system. Without them, DMV puts a hold on your registration. That truck doesn’t move until you’re compliant.
The testing requirement started October 1, 2024. Every compliance deadline from January 1, 2025 forward requires a passing test. You can submit results up to 90 days before your deadline, which gives you time to handle repairs if something fails. But you need to know where you stand before that deadline hits.
We specialize in OBD testing for 2013 and newer diesel engines. We use CARB-certified testing equipment, upload your results directly to the state system, and clear DMV holds in real time. You get proof of compliance immediately. Your trucks stay on the road.
We focus specifically on heavy-duty vehicle compliance for the Vincent and greater Los Angeles area. We’re CARB credentialed, which means we’ve completed the state’s official training and maintain current certification to perform Clean Truck Check testing.
Vincent sits in an area with thousands of trucking operations—small fleets, owner-operators, and single-truck businesses that need reliable compliance testing without the runaround. Most trucking companies in California run ten trucks or fewer. You don’t have time to figure out confusing regulations or track down testers who may or may not be available.
We handle OBD testing for 2013+ diesel trucks and buses over 14,000 pounds GVWR. That’s our lane, and we stay in it.
You bring your 2013 or newer heavy-duty diesel truck to our facility. We connect to your vehicle’s OBD system using CARB-certified testing equipment.
The OBD test pulls diagnostic data directly from your truck’s onboard computer. We’re checking for emissions-related fault codes, readiness monitors, and system performance. If your truck passes, we upload the results immediately to California’s CARB system. You’ll see the DMV hold clear in real time if one was in place.
If something fails, you’ll know exactly what needs repair. You have up to 90 days before your compliance deadline to get repairs done and retest. The state annual compliance fee is $31.18 for 2025.
Testing frequency increases over time. Right now it’s once per year. By 2025, it goes to twice yearly. By October 2027, you’re testing four times per year. Getting ahead of your deadline means you’re not scrambling when repairs are needed.

This service applies only to trucks that are model year 2013 or newer and have a GVWR over 14,000 pounds. Older trucks or lighter vehicles don’t qualify for OBD-based Clean Truck Check testing.
If you operate in California—even if your truck is registered out of state—you need compliance testing. The program covers commercial vehicles, privately-owned trucks, government vehicles, hybrid trucks and buses, and California-registered motorhomes that meet the weight requirement.
Vincent’s location in Los Angeles County puts you in the heart of California’s freight industry. With over 52,000 local freight trucking businesses operating in the state and regulations tightening, compliance isn’t optional. CARB and California Highway Patrol enforce these requirements. Operating without compliance registration results in violations, fines up to $10,000 for shippers who hire non-compliant carriers, and registration blocks that stop your operations cold.
You can’t afford downtime. Every day a truck sits idle costs money. We get you tested, get your results uploaded, and get you back to work.
Any diesel or alternative fuel heavy-duty truck with a gross vehicle weight rating over 14,000 pounds that operates in California needs Clean Truck Check testing. This includes trucks registered in California and out-of-state trucks that drive here.
The OBD testing we provide applies specifically to model year 2013 and newer diesel engines. These trucks have onboard diagnostic systems that CARB-certified equipment can access. If your truck is older than 2013, different testing methods apply, but our service focuses on the 2013+ OBD-equipped vehicles.
Commercial fleets, single-truck owner-operators, private vehicles, and even California-registered motorhomes over 14,000 pounds fall under this requirement. If you’re hauling freight, running a bus service, or operating any heavy-duty diesel in the state, compliance testing is mandatory.
Testing frequency increases over the next few years. For compliance deadlines in 2024, you need one passing test. Starting in 2025, the requirement jumps to twice per year.
By October 2027, OBD-equipped vehicles need testing four times per year. That’s quarterly testing to maintain compliance. The state is ramping up gradually, but the end goal is frequent monitoring to ensure heavy-duty vehicles stay well-maintained and emissions-compliant.
You can submit passing test results up to 90 days before your compliance deadline. This window gives you breathing room to handle repairs if something fails. Don’t wait until the last minute—if your truck fails and needs work, you’ll need time to fix it and retest before your deadline hits.
If your truck fails, you’ll get a detailed report showing exactly what triggered the failure. Usually it’s emissions-related fault codes or readiness monitors that aren’t set. You’ll need to get those issues repaired.
Once repairs are complete, you come back for retesting. You have up to 90 days from your initial test to get a passing result uploaded before your compliance deadline. If you miss your deadline without a passing test on file, DMV places a registration hold on that vehicle.
A registration hold means that truck can’t legally operate in California until you’re compliant. You can’t renew registration, and you risk enforcement action from CARB and California Highway Patrol if you’re caught driving a non-compliant vehicle. Getting repairs done quickly and retesting keeps you legal and operational.
Yes, but it’s not the same smog check you’d get for a passenger car. Heavy-duty diesel trucks over 14,000 pounds GVWR need Clean Truck Check testing, which is a specific CARB compliance program.
For 2013 and newer diesel trucks, this means OBD testing using CARB-certified equipment. The tester must be CARB credentialed, meaning they’ve completed official state training and passed the certification exam. Not every smog shop can perform this testing—you need a facility with the right equipment and credentials.
We’re CARB credentialed and equipped specifically for heavy-duty OBD testing. We upload results directly to the state system, and you get immediate proof of compliance. Regular passenger vehicle smog shops typically can’t handle heavy-duty diesel compliance testing.
Testing costs vary by provider, but you’re typically looking at $50 to $190 per vehicle depending on the service level and whether mobile testing is involved. The state also charges an annual compliance fee of $31.18 for 2025, which increases with California’s Consumer Price Index each year.
That state fee is separate from the testing service fee. You pay it as part of maintaining compliance registration with CARB. It’s not optional—every truck in the program pays it annually.
When you’re comparing testing services, consider turnaround time and convenience alongside price. Cheap testing that takes days to upload results or requires multiple trips costs you more in downtime than you save on the service fee. You need fast, reliable testing that gets your trucks back on the road immediately.
No. If your truck operates in California, you need Clean Truck Check compliance regardless of where it’s registered. The program applies to all heavy-duty vehicles over 14,000 pounds GVWR that drive in the state.
Out-of-state carriers hauling freight into or through California must comply with the same testing requirements as California-registered trucks. CARB and CHP enforce this. If you’re caught operating a non-compliant vehicle, you face violations and fines.
Shippers also have skin in the game. If a shipper hires a non-compliant carrier, they can face fines up to $10,000 for each year that carrier operated without compliance. This creates pressure throughout the supply chain to ensure every truck on the road meets California’s requirements. Get tested before you cross the state line.
