If your truck doesn’t meet California’s Clean Truck Check requirements, you’re looking at registration holds from the DMV. That means your rig sits. Your schedule gets thrown off. Your income takes a hit.
Non-compliance penalties can reach up to $10,000 per vehicle per day. That’s not a scare tactic—it’s what CARB can enforce. Add in the annual compliance fee of $31.18 per vehicle and semi-annual testing requirements, and you’re dealing with a system that doesn’t forgive mistakes.
Getting tested on time keeps your registration active and your truck on the road. You submit passing results up to 90 days before your deadline, which gives you flexibility without cutting it close. You stay ahead of the twice-yearly requirement. You protect your business from unnecessary shutdowns.
We’ve been helping commercial drivers in Riverside, CA pass inspections for nearly 20 years. We’re CARB credentialed, which means we’re authorized to perform Heavy-Duty Inspection and Maintenance testing and submit results directly to the state.
Riverside sits at the center of one of the busiest freight corridors in California. The Inland Empire handles massive volumes of truck traffic daily, and that means local operators need reliable testing they can count on. We understand the pressure you’re under to stay compliant without losing time.
We don’t test older trucks or lighter vehicles. This service applies only to 2013 and newer diesel or diesel hybrid trucks with a GVWR over 14,000 pounds. If your truck qualifies, we’ll get you through the process efficiently.
You bring your 2013 or newer heavy-duty truck to our Riverside location. We verify that your vehicle qualifies—diesel or diesel hybrid engine, GVWR over 14,000 pounds. If it doesn’t meet those specs, we’ll let you know upfront.
Once confirmed, we use a CARB certified OBD testing device to scan your truck’s onboard diagnostics. The device pulls engine data directly from your truck’s computer system. We’re checking emissions performance against California’s standards for heavy-duty vehicles.
If your truck passes, we submit the results electronically to CARB the same day. You’ll receive confirmation that your compliance is on file. If there’s an issue, we’ll explain what needs attention before you can pass. Most tests are completed quickly, so you’re not sitting around all day.
You can submit passing results up to 90 days before your compliance deadline. That early window gives you room to plan around your schedule instead of scrambling at the last minute.

You’re getting CARB certified OBD emissions testing performed by credentialed testers who know California’s heavy-duty truck regulations. We scan your engine’s diagnostic data using state-approved equipment. We verify compliance with CARB diesel compliance standards. We submit passing results directly to the state system.
Riverside, CA is home to over 314,000 people and sits in the heart of the Inland Empire—a region with 4.74 million residents and one of the highest concentrations of freight activity in the country. Trucks move through here constantly. That makes local access to CARB emissions testing critical for operators who can’t afford to drive hours out of their way.
California has over 1 million heavy-duty vehicles on the road. Emissions from trucks and buses account for more than 50% of mobile pollution statewide. That’s why CARB’s Clean Truck Check program exists—and why compliance isn’t optional. Starting in October 2027, OBD-equipped vehicles will be required to test four times per year instead of twice. The requirements are tightening, not loosening.
You’re paying the $31.18 annual compliance fee per vehicle no matter what. The testing itself is what keeps you legal. You need a facility that can handle the process correctly and get your results submitted without delays.
Your truck qualifies if it’s model year 2013 or newer, has a diesel or diesel hybrid engine, and has a gross vehicle weight rating over 14,000 pounds. Those are the only vehicles that fall under California’s Clean Truck Check program.
If your truck is older than 2013, it doesn’t require this specific test. If it’s under 14,000 pounds GVWR, it’s not part of the program either. CARB’s regulations are specific about which vehicles need OBD emissions testing.
When you call or come in, we’ll verify your truck’s specs before scheduling. We don’t want to waste your time if your vehicle doesn’t qualify for this service.
Right now, most qualifying trucks need to pass Clean Truck Check testing twice per year—that’s semi-annual compliance. You’ll also pay the annual compliance fee of $31.18 per vehicle each year.
You can submit passing test results up to 90 days before your compliance deadline. That early submission window is designed to give you flexibility. If you wait until the last minute and something fails, you’re cutting it close with the DMV.
Starting in October 2027, the requirement increases to four times per year for OBD-equipped vehicles. CARB is tightening the schedule, so plan accordingly. The sooner you build testing into your routine, the less disruptive it becomes.
If your truck fails, we’ll explain what the OBD scan flagged. Usually it’s an emissions-related fault code or a system that’s not performing within CARB’s limits. You’ll need to address the issue before you can pass and submit results.
You won’t be able to meet your compliance deadline until the problem is fixed and you pass a retest. That can lead to registration holds from the DMV, which means your truck can’t legally operate until compliance is restored.
We don’t perform repairs, but we’ll point you in the right direction. Once the issue is resolved, come back for a retest. If it passes, we’ll submit the results to CARB immediately.
Testing costs vary depending on the provider, but you’re typically looking at somewhere between $50 and $135 per vehicle for standard service. Mobile testing services that come to your location usually charge more—sometimes $99 to $190 or higher per unit.
That’s separate from the $31.18 annual compliance fee you pay directly to CARB. The fee is non-negotiable and applies to every qualifying vehicle. The testing itself is what you’re shopping for.
We focus on getting you through the process correctly and quickly. You’re not paying for unnecessary add-ons or upsells. You’re paying for CARB certified testing that meets state requirements and keeps your registration active.
Yes. Most Clean Truck Check tests are completed the same day you bring your truck in. The OBD scan itself doesn’t take long—we’re pulling data from your truck’s computer and checking it against CARB standards.
The key is making sure your truck qualifies before you show up. If it’s a 2013 or newer diesel or diesel hybrid with a GVWR over 14,000 pounds, you’re good. If it doesn’t meet those specs, we can’t test it under this program.
Call ahead if you want to confirm availability or ask questions about your specific vehicle. We’re here to make the process as efficient as possible so you can get back on the road.
California’s Clean Truck Check program exists because heavy-duty vehicles are a major source of air pollution. Trucks and buses account for more than 50% of mobile emissions statewide, even though they make up a smaller percentage of total vehicles on the road.
CARB uses OBD emissions testing to monitor whether newer diesel trucks are performing within acceptable limits. The program targets 2013 and newer trucks because those model years are equipped with onboard diagnostic systems that can be scanned electronically.
The goal is to catch emissions problems early and keep the dirtiest trucks off the road. Compliance isn’t optional—it’s tied directly to your vehicle registration. If you don’t test and pass on schedule, the DMV can place a hold on your registration, which grounds your truck until you’re compliant.
