Starting January 1, 2024, every heavy-duty truck operating in California needs proof of CARB compliance. No exceptions. If you’re running a semi truck, box truck, or any commercial vehicle over 14,000 pounds GVWR that’s model year 2013 or newer, you need this test twice a year.
The penalty for skipping it? Up to $10,000 per vehicle per day. Your registration gets flagged. Your trucks sit idle. And if you’re a shipper hiring non-compliant carriers, you’re on the hook too.
CARB diesel compliance isn’t optional anymore. It’s the cost of doing business in California. The good news is the actual test takes under 20 minutes when you work with a CARB certified smog check provider who knows what they’re doing. You get your results uploaded to the state database immediately, your compliance status updates, and your trucks stay on the road.
We focus exclusively on heavy-duty vehicle compliance for trucks that are 2013 or newer and over 14,000 pounds. That’s it. No passenger cars, no light-duty vehicles. Just commercial trucks that need California CARB compliant testing.
Every tester on our team is CARB credentialed, which means they’ve completed the official state training course, passed the certification exam with at least 80%, and performed a minimum of 250 Clean Truck Checks. We’re licensed, insured with $2 million in liability coverage, and we use only CARB-certified OBD test devices.
Beverly Hills and the surrounding Los Angeles County area has thousands of commercial vehicles that need this service. We’re here because fleet operators, owner-operators, and logistics companies need a reliable place to handle CARB truck regulations without the runaround.
First, we verify your truck qualifies. That means checking the model year (2013 or newer) and the GVWR (over 14,000 pounds). If your truck doesn’t meet both requirements, this test doesn’t apply to you.
Next, we connect to your truck’s onboard diagnostics system. This is an OBD test, not a tailpipe smog test. We’re pulling emissions data directly from your truck’s computer. The test checks for fault codes, monitors readiness status, and confirms your emissions systems are functioning correctly.
The whole process takes less than 20 minutes in most cases. Once the test is complete, we upload the results directly to the CARB database. You’ll receive documentation showing your compliance status, and the state updates your record immediately. If your truck passes, you’re good for the next six months. If it doesn’t, we’ll tell you exactly what needs attention before you can retest.
You can submit a passing test up to 90 days before your deadline, so there’s no reason to wait until the last minute. California-registered trucks and out-of-state trucks operating here both need this. The deadlines are different depending on your registration, but the test is the same.

You get a full OBD emissions test performed by a CARB credentialed tester using state-certified equipment. We check your truck’s diagnostic system, verify emissions controls are working, and document everything according to CARB standards.
Results get uploaded to the state database the same day. You receive a compliance certificate and documentation for your records. If you’re managing a fleet, we can coordinate testing schedules for multiple vehicles to minimize disruption.
Beverly Hills sits in the heart of Los Angeles County, where commercial vehicle traffic is constant. Logistics companies, construction fleets, delivery services, and independent owner-operators all move through this area. The concentration of high-value commercial operations here means downtime is expensive. A truck sitting idle costs between $300 and $900 per day in lost revenue, not counting the penalties for non-compliance.
The testing requirement is semi-annual right now, but it’s increasing to four times per year within three years. That means more frequent testing is coming. Getting set up with a reliable CARB emissions testing provider now saves you scrambling later when the deadlines tighten.
Any truck with a gross vehicle weight rating over 14,000 pounds that’s model year 2013 or newer needs CARB compliance testing if it operates in California. This includes semi trucks, box trucks, delivery trucks, tow trucks, large RVs, and other heavy-duty commercial vehicles.
The key is both conditions have to be true. If your truck is older than 2013, this test doesn’t apply. If it’s under 14,000 pounds GVWR, it doesn’t apply. But if you’re running a 2013 or newer truck over that weight threshold, you need this test twice a year starting in 2024.
It doesn’t matter if your truck is registered in California or out of state. If you’re operating here, you need proof of compliance. Out-of-state vehicles have different deadline schedules, but the testing requirement is the same.
Right now, most heavy-duty trucks need CARB emissions testing twice per year. That’s semi-annual testing, meaning every six months. The specific deadlines depend on whether your truck is California-registered or out-of-state registered.
For California-registered trucks, your compliance deadline is tied to your registration renewal. For out-of-state trucks operating in California, the deadlines start based on when you first operate here. You’ll need to track your schedule carefully because missing a deadline triggers penalties and registration holds.
In three years, the testing frequency increases to four times per year. That’s quarterly testing. CARB is tightening the requirements progressively, so what you’re doing now will change. The best approach is to set reminders and test early. You can submit passing results up to 90 days before your deadline, which gives you a buffer if something comes up.
If your truck fails, you’ll get a detailed report showing exactly what triggered the failure. Usually it’s a fault code in the emissions system, a monitor that isn’t ready, or a component that’s not functioning correctly. The test results tell you what needs repair.
You’ll need to fix the issue and retest. There’s no penalty for failing the test itself, but you can’t operate legally in California without a passing result. That means your truck stays parked until it passes, which is where the real cost comes in.
Most failures are fixable. Sometimes it’s as simple as completing a drive cycle to set the monitors. Other times you need actual repairs to the diesel particulate filter, the exhaust system, or the emissions controls. Once the repairs are done, you come back for a retest. The goal is to catch problems early so you’re not dealing with a failure right before your deadline when you have no time to fix it.
The test itself is quick and straightforward, and the cost is a fraction of what you’d pay in penalties or downtime. Most CARB certified smog check providers charge between $50 and $150 per test depending on the vehicle and location. There’s also a $30 annual compliance fee per vehicle that goes directly to the state.
Compare that to the alternative. Non-compliance fines start at $10,000 per vehicle per day. If your registration gets flagged, your truck can’t legally operate. If you’re a shipper and you hire a non-compliant carrier, you’re liable for penalties too. The math is simple.
The bigger cost is downtime. If you’re taking a truck out of service for 1-3 hours to handle testing, that’s $300 to $900 in lost revenue per vehicle. That’s why working with a provider who can test quickly and upload results immediately matters. You’re not paying for the test. You’re paying to stay compliant and keep your trucks working.
Some CARB credentialed testers offer mobile service where they come to your location with the testing equipment. This works well for fleets with multiple vehicles or for operators who can’t afford to take trucks off the road and drive them to a testing site.
Mobile testing uses the same CARB-certified OBD devices and follows the same procedures as shop-based testing. The advantage is convenience. Your trucks stay at your yard, the tester comes to you, and you can schedule multiple vehicles back-to-back without disrupting operations.
Not every provider offers mobile service, and those who do typically require a minimum number of vehicles or charge a trip fee. But if you’re managing a fleet in Beverly Hills or the surrounding Los Angeles County area, it’s worth asking. The time savings alone can justify the cost, especially when you’re coordinating semi-annual testing for multiple trucks.
Yes. If you’re operating a heavy-duty truck in California, you need CARB compliance regardless of where your truck is registered. Out-of-state trucks, Canadian trucks, and Mexican trucks all fall under the same California CARB compliant requirements if they’re driving here.
The difference is the deadline structure. Out-of-state vehicles have compliance deadlines that start based on when they first operate in California, not based on registration renewal dates. You’ll need to track your specific schedule because the state assigns deadlines individually.
Starting in 2025, both California-registered and out-of-state vehicles move to recurring six-month compliance cycles. That means if you’re running routes into California regularly, you need to plan for semi-annual testing just like local operators. The penalties for non-compliance are the same regardless of where your truck is registered, so don’t assume being out of state gives you a pass.
