Hear from Our Customers
You’re running 2013 or newer trucks over 14,000 pounds. That means Clean Truck Check applies to you, and the state isn’t playing around with enforcement anymore.
Registration holds ground your trucks immediately. Fines start at $1,000 per vehicle per day and climb to $75,000 depending on what CARB finds. If you’re hauling to ports or freight facilities, non-compliant vehicles get turned away at the gate.
The testing requirement is twice a year right now. By October 2027, it jumps to quarterly for OBD-equipped vehicles. You need a CARB-credentialed tester who knows the CTC-VIS system, has the right diagnostic equipment, and can update your compliance status the same day.
We bring the testing to your yard in South San Jose Hills. You don’t lose a day taking trucks to a facility. You don’t wait in line. Your drivers stay on schedule, and your compliance gets handled without the usual headache.
We’ve been handling emissions compliance since 2005. We’re CARB-credentialed testers with direct access to the CTC-VIS database, which means your results get reported instantly and your trucks stay legal.
South San Jose Hills sits right in the middle of major freight corridors. You’ve got the I-280 nearby, access to City of Industry distribution centers, and proximity to ports that require Clean Truck Check compliance for entry. We work with fleet operators, owner-operators, and commercial carriers throughout the San Gabriel Valley who need reliable CARB emissions testing without the runaround.
We carry $2,000,000 in liability insurance with a Mobile Service Rider. Most mobile testers don’t have proper coverage. We do, and we’re cleared to work at airports, port terminals, and government facilities. You’re not taking a risk when you book with us.
You schedule a time that works for your operation. We show up at your location in South San Jose Hills with CARB-certified diagnostic equipment that meets SAE J1667 specifications.
For 2013 and newer diesel engines over 14,000 pounds GVWR, we’re running OBD-based emissions testing. We plug into your truck’s onboard diagnostics, pull the data CARB requires, and check for any fault codes or emissions system issues that would trigger a failure.
If your truck passes, we update the CTC-VIS system immediately. Your compliance certificate is active, your registration hold risk is cleared, and you’re good for the next six months. If something flags, we’ll tell you exactly what needs fixing before the retest. No surprises, no vague explanations.
The whole process takes about 30 minutes per vehicle if everything’s running clean. You’re not losing half a day. You’re getting it done while your trucks are parked and your team is working on other things. That’s the point of mobile service.

This is mobile CARB compliant testing for semi trucks and heavy-duty vehicles with 2013 or newer engines and a GVWR over 14,000 pounds. If your trucks don’t meet both of those requirements, this service doesn’t apply.
You’re getting a CARB-credentialed tester who’s completed the state’s official training and passed the exam. We’re using approved diagnostic tools that connect directly to your truck’s OBD system. We’re not guessing or using outdated equipment.
South San Jose Hills is surrounded by freight activity. You’ve got the San Gabriel Valley’s industrial backbone right here, with access to Highway 12, the I-280 corridor, and distribution centers that feed the entire region. If you’re running trucks in or out of this area, you’re dealing with CARB enforcement at weigh stations, roadside checks, and port entries.
We handle the CTC-VIS reporting, the compliance fee confirmation, and the documentation you need for roadside inspections. You get same-day results. You get a compliance certificate that’s recognized statewide. And if you’re managing a fleet, we’ll track your testing schedules and send reminders before deadlines hit.
Your truck gets flagged in the CTC-VIS system, and you’ll need to fix whatever caused the failure before you can retest. Common issues include fault codes in the emissions system, malfunctioning sensors, or OBD communication problems.
We’ll tell you exactly what failed and what needs repair. You’re not getting a vague “check engine” explanation. Once you’ve handled the repairs, we’ll come back and retest at no additional charge.
The key is addressing it fast. A failed test doesn’t trigger fines immediately, but if you keep operating the vehicle without fixing the issue and getting retested, you’re risking registration holds and penalties. CARB tracks this, and enforcement is active throughout California, especially in high-traffic areas like South San Jose Hills and the surrounding San Gabriel Valley.
Right now, it’s twice a year for trucks with 2013 or newer engines over 14,000 pounds GVWR. That’s the current Clean Truck Check requirement, and it’s non-negotiable if you’re operating in California.
Starting in October 2027, the frequency increases to four times a year for OBD-equipped vehicles. That means quarterly testing becomes the standard. If you’re managing multiple trucks, you’re looking at a rotating schedule that needs to stay organized or you’ll miss deadlines.
We handle scheduling reminders and fleet tracking if you need it. The goal is keeping you ahead of the deadlines so you’re not scrambling last minute or risking a registration hold because a test expired. Mobile service makes this easier because we come to you, and you’re not pulling trucks off the road to sit at a testing facility.
No. This service only applies to trucks that are model year 2013 or newer and have a GVWR over 14,000 pounds. Both conditions have to be met.
If your trucks are older than 2013 or weigh less than 14,000 pounds, they’re not subject to the Clean Truck Check program, and this testing doesn’t apply. CARB’s OBD-based emissions requirements specifically target the newer generation of heavy-duty diesel engines, which is why the 2013 cutoff exists.
If you’re unsure whether your fleet qualifies, check your vehicle registration or the manufacturer’s GVWR rating. We’re not going to waste your time testing vehicles that don’t meet the criteria. This is specialized compliance for heavy-duty commercial trucks operating under California’s strictest emissions regulations.
Because we’re coming to you with certified equipment, proper insurance, and the expertise to handle everything on-site. You’re not losing a driver’s time, fuel costs, or a half-day of productivity taking trucks to a facility and waiting in line.
Most mobile testers don’t carry the insurance coverage required for commercial work. We carry $2,000,000 in liability with a Mobile Service Rider, which means we’re covered to work at your location, at ports, and at secured facilities. That’s not standard, and it’s not cheap to maintain.
You’re also paying for convenience and speed. We schedule around your operation, test multiple trucks in one visit, and update your compliance status in the CTC-VIS system the same day. If you’re running a fleet in South San Jose Hills with tight delivery schedules, that’s worth more than saving $50 and losing half a day per truck.
You need your compliance certificate from the CTC-VIS system, which proves your truck passed and is current. Keep a copy in the vehicle for roadside inspections, and keep digital records for your fleet files.
CARB enforcement happens at weigh stations, roadside checks, and port entries throughout California. If you’re stopped and can’t produce proof of current compliance, you’re looking at fines and potential vehicle impoundment until you can verify your status.
We provide the official documentation after every test, and your compliance status is updated in the state database immediately. If you’re managing multiple trucks, we recommend keeping a centralized tracking system with test dates, expiration dates, and upcoming deadlines. We can help with that if you need fleet management support. The goal is staying ahead of enforcement, not reacting to it after you’ve been flagged.
Yes. CARB uses roadside emissions monitoring devices, automated license plate readers, and active enforcement at weigh stations. They’re not waiting for you to come to them. They’re checking compliance in real time.
Non-compliant trucks get hit with registration holds immediately, which grounds the vehicle until you fix the issue and pass testing. Fines range from $1,000 to $75,000 per vehicle per day depending on the violation. Shippers who hire non-compliant carriers can face up to $10,000 per year in penalties.
South San Jose Hills is surrounded by major freight routes, including access to the I-280 corridor and distribution centers in City of Industry. If you’re running trucks through this area, you’re in a high-enforcement zone. CARB isn’t issuing warnings anymore. They’re issuing fines, and they’re tracking repeat offenders. Staying compliant isn’t optional if you want to keep operating in California.
