You’re running a business, not chasing paperwork. But California’s CARB regulations don’t care about your schedule, and the penalties for non-compliance hit hard—up to $10,000 per vehicle per day.
That’s not a scare tactic. That’s the reality if your heavy-duty trucks aren’t compliant with California’s Clean Truck Check requirements. And it gets worse: the DMV can place a registration hold on your vehicle, which means it’s grounded until you fix the problem.
We handle CARB compliance testing for model year 2013 and newer trucks with a GVWR over 14,000 pounds. Our mobile service comes directly to your location in Arcadia, so your trucks stay on the road making money instead of sitting at a testing facility. You get certified results fast, usually within 15-30 minutes, and you’re back to business.
We’ve been serving Arcadia and the surrounding areas for over 15 years. We’re not new to CARB compliance—we’ve been helping fleet operators and owner-operators navigate California’s emissions regulations since they started tightening the rules.
Our technicians are CARB certified and credentialed, which means they’ve completed the required training and passed the state exam. We use approved testing equipment and follow the exact protocols CARB requires for the Clean Truck Check program.
Arcadia sits right off the 210, which makes it a hub for commercial traffic moving through Southern California. We understand the pressure you’re under to keep trucks moving, and we’ve built our service around that reality.
First, we confirm your truck qualifies for the Clean Truck Check program. That means it’s model year 2013 or newer and has a GVWR over 14,000 pounds. If your truck doesn’t meet both requirements, it’s not eligible for this testing.
Once we’re on-site at your location in Arcadia, we connect to your truck’s onboard diagnostics system. The OBD test pulls data directly from your vehicle’s emissions control systems. We’re checking for fault codes, system readiness, and whether your truck meets California’s emissions standards.
The test itself takes about 15-30 minutes in most cases. If your truck passes, we submit the results directly to CARB and you receive certification. If there’s an issue, we’ll tell you exactly what needs to be addressed and can often handle repairs on the spot. You’re not left guessing what’s wrong or where to go next.

You get a full OBD emissions test performed by a CARB-certified technician using state-approved equipment. We’re testing your truck’s emissions control systems to verify they’re working as designed and meeting California’s air quality standards.
This isn’t a visual inspection or a quick check. We’re pulling diagnostic data from your truck’s computer system and comparing it against CARB’s requirements. If your diesel particulate filter, NOx sensors, or other emissions components aren’t functioning properly, the test will catch it.
In Arcadia and across California, heavy-duty vehicles account for more than half of the smog-causing pollution despite making up only 3% of vehicles on the road. That’s why CARB enforcement is aggressive. They use roadside monitoring devices to identify high-emitting trucks and issue notices. Getting ahead of compliance protects you from those enforcement actions and the penalties that follow.
The annual compliance fee for 2025 is $31.18 per vehicle. Starting in 2027, trucks with OBD systems will need quarterly testing. Right now, testing frequency depends on your fleet size and registration status, but the requirements are only getting stricter.
Yes, if your truck operates on California roads. CARB compliance applies to any heavy-duty diesel truck over 14,000 pounds GVWR operating in California, regardless of where it’s registered.
Out-of-state operators often miss this requirement and get hit with penalties during roadside inspections or weigh station checks. California doesn’t give exemptions based on registration location. If you’re doing business here, your truck needs to meet California’s emissions standards.
The Clean Truck Check program requires testing for model year 2013 and newer trucks. Older trucks fall under different CARB regulations, but they’re not eligible for the OBD-based testing we provide. Make sure you know which rules apply to your specific vehicle.
The actual OBD test takes about 15-30 minutes in most cases. Because we come to your location in Arcadia, your truck doesn’t need to travel to a testing facility or wait in line.
Traditional smog check facilities can tie up a truck for 1-3 hours when you factor in travel time, waiting, and the inspection itself. That’s $300-$900 in lost productivity per vehicle. Our mobile service eliminates that downtime entirely.
If your truck passes, you’re done. If there’s a fault code or emissions issue, we’ll diagnose the problem on-site and discuss repair options. In many cases, we can handle repairs immediately so you’re not making multiple appointments or losing additional days of operation.
We’ll tell you exactly what’s wrong and what needs to be fixed. The OBD system provides specific fault codes that identify which emissions components aren’t functioning properly.
Common issues include diesel particulate filter problems, NOx sensor failures, or exhaust gas recirculation system malfunctions. These aren’t minor problems you can ignore—they’ll prevent your truck from passing and put you at risk for penalties.
We can often perform repairs on-site, depending on the issue. Once repairs are complete, we retest your truck and submit passing results to CARB. You’re not compliant until you have a passing test on file, and the DMV can place a registration hold until that happens. Getting it fixed quickly protects your ability to operate legally in California.
Not all semi trucks qualify for the Clean Truck Check program. Only model year 2013 and newer trucks with a GVWR over 14,000 pounds are eligible for OBD-based emissions testing.
If your truck is older than 2013, it falls under different CARB regulations and isn’t eligible for the testing we provide. Lighter trucks under 14,000 pounds also don’t qualify, even if they’re diesel-powered.
CARB estimates that 532,000 of the 1.8 million medium and heavy-duty vehicles operating daily in California are subject to fleet requirements. If your truck meets the year and weight criteria, compliance isn’t optional. The regulations are designed to reduce smog-causing pollution from heavy-duty vehicles, which account for over half of California’s transportation-related emissions despite being a small percentage of total vehicles.
The annual CARB compliance fee for 2025 is $31.18 per vehicle. Testing frequency depends on your fleet size and whether your trucks are registered in California or out of state.
Starting in 2027, vehicles with OBD systems will be subject to quarterly testing. Right now, the requirements vary, but all deadlines require a passing test submission. Missing a deadline can trigger DMV registration holds and daily fines.
Our mobile testing service eliminates the hidden costs of compliance—no lost productivity from driving to a facility, no waiting in line, no multi-hour downtime. When you factor in the cost of taking a truck out of service for traditional testing, mobile compliance testing pays for itself immediately. And compared to the $10,000 per day penalties for non-compliance, the testing fee is negligible.
Yes, that’s exactly how our mobile service works. We bring the testing equipment directly to your location in Arcadia, whether that’s your yard, a job site, or wherever your trucks are parked.
You don’t need to pull trucks off jobs or send drivers across town. We schedule a time that works for your operation, show up with certified equipment, and complete testing on-site. It’s faster and more convenient than traditional smog check facilities.
Arcadia’s location near the 210 makes it easy for us to reach you quickly. We serve fleet operators, owner-operators, and commercial vehicle owners throughout the area. If you have multiple trucks that need testing, we can handle them all in one visit and get your entire fleet compliant without disrupting your schedule.
