You’re running a tight operation in Cudahy. Every day a truck sits idle waiting for compliance testing costs you $500 or more in lost revenue. Every missed deadline risks fines that start at $1,000 per vehicle per day and can climb to $10,000.
The Clean Truck Check program isn’t optional anymore. If you’re operating heavy-duty trucks model year 2013 or newer with a GVWR over 14,000 pounds, you need semi-annual testing. Starting October 2027, that becomes quarterly for OBD-equipped vehicles.
Here’s what changes when you work with a mobile testing service that actually understands trucking. Your trucks stay on your lot. We bring certified equipment to you, run the OBD Clean Truck Check in minutes, and submit results directly to CARB. You get back to work. No waiting at testing facilities. No taking vehicles out of rotation. No wondering if you’re compliant.
The DMV is already placing registration holds on non-compliant vehicles. That means your truck can’t be renewed, can’t be registered, and technically can’t operate legally in California until you pass inspection. We help you avoid that scenario entirely.
All SMOG Motors operates right here in Cudahy, where trucking and logistics keep the local economy moving. We know the businesses on Atlantic Avenue. We understand the pressure you’re under to keep trucks compliant while maintaining delivery schedules.
We’re state-certified for smoke opacity and emissions control system testing. That certification isn’t just a piece of paper—it means our test results are valid with CARB, and you won’t have to retest somewhere else. We’ve been doing this for over 15 years, and we’re insured, which 99% of mobile testers aren’t.
When CARB makes regulatory changes or you get a confusing notice from the DMV, we can communicate directly with CARB to resolve issues fast. That kind of access matters when your registration is on the line.
First, you schedule a time that works for your operation. We’re available 24/7 because we know trucks don’t run on a 9-to-5 schedule. We come to your location anywhere in Cudahy with our certified testing equipment.
The actual Clean Truck Check takes minutes, not hours. For 2013 and newer heavy-duty vehicles, we connect to your truck’s OBD system and run the emissions diagnostics. The system checks for proper emissions control function and flags any issues that would cause a failure.
If your truck passes, we submit results directly to the California Air Resources Board through the CTC-VIS portal. CARB updates your compliance status, and you’re good until your next testing deadline. If there’s a failure, we offer 50% off the retest and can often identify exactly what needs repair.
You get documentation immediately. No waiting for results in the mail. No wondering if CARB received your test. The whole process is designed to keep your trucks moving and your business operating without interruption.

Let’s cut through the confusion. If you operate heavy-duty diesel trucks, hybrids, or alternative-fuel vehicles model year 2013 or newer with a GVWR over 14,000 pounds in California, you must comply with the Clean Truck Check program. This applies to both fleet operators and owner-operators.
You need semi-annual testing right now. That means twice a year, your qualifying trucks must pass an emissions inspection. There’s also an annual compliance fee of $31.18 per vehicle due by specific deadlines based on your VIN. Miss those deadlines and you’re looking at late fees, fines, and registration holds.
In Cudahy, where small trucking companies like J & S Transport, GT Transport Express, and dozens of others keep goods moving through Southern California, staying compliant isn’t just about avoiding penalties. It’s about protecting your ability to operate. The DMV has already started enforcing registration holds as of August 2024, which means non-compliant trucks literally cannot be registered.
We handle the testing portion. We also provide free assistance with registering in the CTC-VIS portal if you haven’t set that up yet. The total cost for mobile testing is $95 per vehicle, and we include a free retest if your results come back as “not ready” or if you fail and need to address repairs.
The regulations are only getting stricter. By October 2027, OBD-equipped vehicles move to quarterly testing. The state is serious about reducing emissions from heavy-duty vehicles, which make up only 3% of vehicles on California roads but produce over half of smog-causing pollution.
Your truck qualifies if it’s model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds. This includes heavy-duty diesel trucks, hybrids, and alternative-fuel vehicles. The program specifically targets newer trucks with advanced emissions systems.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this particular program doesn’t apply to you. You might still have other CARB requirements depending on your vehicle type, but Clean Truck Check is specifically for that 2013+ heavy-duty category.
The easiest way to know for sure is to check your vehicle registration or VIN. We can also verify eligibility when you call to schedule. Don’t assume you’re exempt just because you haven’t received a notice—CARB expects you to know the requirements and comply proactively.
Right now, you need semi-annual testing. That’s twice per year for each qualifying vehicle. The testing windows are based on your vehicle identification number and the compliance deadlines CARB sets for your fleet.
Starting in October 2027, the requirement increases to quarterly testing for OBD-equipped vehicles. That means four times per year. The state is ramping up testing frequency to ensure emissions systems stay functional throughout the year, not just at inspection time.
You also have an annual compliance fee of $31.18 per vehicle that’s separate from testing. Missing either the testing deadline or the fee deadline can trigger penalties, so it’s worth setting reminders or working with someone who tracks this for you. We help our regular customers stay on top of their testing schedule so nothing falls through the cracks.
If your truck fails, you’ll get a detailed report showing exactly what triggered the failure. Usually it’s an emissions control system malfunction, a sensor issue, or the OBD system showing “not ready” status because monitors haven’t completed their diagnostic cycles.
You’ll need to repair whatever caused the failure and then retest. We offer 50% off retests, so you’re not paying full price twice. In many cases, we can point you toward what needs fixing based on the diagnostic codes, which saves you time and money on troubleshooting.
Once repairs are complete and your truck passes, we submit the passing results to CARB immediately. Your compliance status updates and you’re back in good standing. The key is addressing failures quickly—every day you operate a non-compliant truck increases your risk of fines and registration problems. We make the retest process as fast as possible so you’re not losing revenue while your truck sits waiting.
Yes. That’s exactly what we do. We bring certified testing equipment directly to your yard, warehouse, or wherever your trucks are located in Cudahy. You don’t have to drive anywhere or take vehicles out of service to visit a testing facility.
Mobile testing saves you the time and cost of transporting trucks to a smog station. When you’re running a tight operation, that matters. We schedule around your needs, including nights and weekends, because we’re available 24/7.
The test itself takes just minutes per vehicle. We connect to the OBD system, run the diagnostics, and submit results to CARB on the spot. You get documentation immediately and your trucks stay on-site the entire time. For fleets with multiple vehicles, we can test several trucks in one visit, which makes compliance even more efficient.
Our mobile Clean Truck Check service costs $95 per vehicle. That includes coming to your location in Cudahy, running the certified OBD emissions test, and submitting results directly to CARB. No hidden fees.
If your truck fails and needs a retest after repairs, we offer 50% off the second test. We also provide free assistance with registering in the CTC-VIS portal if you haven’t set that up yet, which is required for compliance tracking.
Compare that to the cost of non-compliance. CARB fines start at $1,000 per day per vehicle and can reach $10,000 per day for serious violations. Add in the $500+ per day you lose when a truck sits idle, plus the hassle of registration holds that prevent you from renewing your vehicle. Spending $95 to stay compliant is a lot cheaper than dealing with penalties and downtime.
The penalties are steep and they’re being enforced. CARB can fine you $1,000 per day per vehicle for non-compliance, with some violations reaching $10,000 per vehicle per day. Those aren’t theoretical—they’re issuing these fines.
The DMV also places registration holds on non-compliant vehicles. That means you cannot renew your registration until you pass inspection and show proof of compliance. Operating a truck with an expired or held registration creates additional legal problems and liability issues.
Beyond the official penalties, there’s the operational cost. If your truck gets flagged and pulled off the road during an inspection, you’re losing revenue every day it sits. You’re scrambling to find testing, possibly paying rush fees, and dealing with angry customers whose deliveries are delayed. The smartest move is staying ahead of deadlines with regular testing. It’s a lot less painful than trying to fix compliance problems after you’ve already been caught.
