You’re running a tight operation. Every day a truck sits waiting for compliance testing is a day you’re losing money. Your drivers are ready, your loads are lined up, but without a passing Clean Truck Check, the DMV won’t let you renew registration.
That’s where this gets expensive fast. A single truck sitting idle can cost you $500 or more per day in lost revenue. Multiply that across a small fleet and you’re looking at real money walking out the door.
We bring CARB certified testing directly to your location in Inglewood, CA. If your truck is model year 2013 or newer and weighs over 14,000 lbs GVWR, we scan the OBD system, transmit results directly to CARB, and clear any DMV holds the same day for passing vehicles. You only pay when your truck passes. No hidden fees, no waiting around at a shop, no multi-day delays eating into your bottom line.
All SMOG Motors operates as a CARB credentialed testing provider serving Inglewood, CA and the surrounding Los Angeles County area. We’re not new to emissions compliance, and we’re definitely not guessing our way through California’s heavy-duty regulations.
Inglewood sits at the crossroads of major freight corridors—Interstate 405, Interstate 105, Century Boulevard feeding LAX cargo operations, and commercial zones supporting SoFi Stadium logistics. That means heavy truck traffic, tight delivery windows, and zero tolerance for downtime.
We built this service specifically for operators who can’t afford to park trucks for days waiting on compliance testing. You’re dealing with CARB deadlines, potential fines up to $10,000 per vehicle per day, and the very real threat of registration holds that stop your operation cold. We handle the testing, the paperwork, and the CARB transmission so you can focus on what actually makes you money.
First, you schedule an appointment. We come to your location anywhere in Inglewood, CA—your yard, your job site, wherever your truck is parked. No need to drive to a testing station and wait in line.
When we arrive, we connect our CARB certified scanning device to your truck’s OBD port. This only works on 2013 and newer model year diesel engines over 14,000 lbs GVWR, because that’s what the Clean Truck Check regulation requires. Older trucks or lighter vehicles aren’t part of this program.
The scan pulls emissions data directly from your truck’s onboard diagnostics. If your truck passes, we transmit the results electronically to CARB’s database right there on site. CARB processes the pass, clears any DMV registration hold, and you’re done. The whole process typically takes 30 minutes or less for a passing vehicle.
If your truck doesn’t pass, you don’t pay. We’ll explain what triggered the failure and what needs to be addressed before retesting. Most failures relate to check engine lights, emission system faults, or incomplete readiness monitors—all fixable issues.
You’ll need to submit a passing test twice per year for most heavy-duty trucks, and you can submit up to 90 days before your compliance deadline. That gives you flexibility to plan around your schedule instead of scrambling at the last minute.
Ready to get started?
You get a CARB credentialed tester who shows up with certified equipment, scans your 2013 or newer heavy-duty truck over 14,000 lbs GVWR, and uploads passing results directly to California’s compliance database. That’s the core of it.
But here’s what matters more: you get someone who understands that your truck sitting still is costing you real money. Inglewood’s location near LAX means freight doesn’t wait. Construction projects around SoFi Stadium and the Forum run on tight schedules. Delivery routes through South Bay and downtown LA have zero flexibility for delayed trucks.
We work around your operation, not the other way around. Same-day appointments are available for most Inglewood locations. Testing starts at $79 per truck that passes, and if it doesn’t pass, you pay nothing. We’re not interested in charging you for bad news.
The compliance deadline is real. CARB started enforcing Clean Truck Check requirements on January 1, 2025, and they’re using roadside monitoring and automated license plate readers to catch non-compliant vehicles. Registration holds go into effect immediately for trucks that miss testing deadlines. You can’t renew, you can’t legally operate, and every day that passes racks up potential penalties.
This isn’t scare tactics—it’s just how the regulation works. You need a passing test on file with CARB, submitted semi-annually, or your trucks stop earning. We make that process as fast and painless as possible so you can get back to work.
Your truck qualifies if it meets two specific criteria: model year 2013 or newer, and a gross vehicle weight rating over 14,000 lbs. Both conditions must be true. This regulation applies to diesel engines and diesel hybrid engines operating in California, regardless of where your truck is registered.
If your truck is older than 2013, it’s not subject to Clean Truck Check requirements. If it weighs less than 14,000 lbs GVWR, same thing—not covered under this program. CARB designed this regulation specifically for newer heavy-duty diesel trucks because those vehicles have OBD systems that can be scanned electronically.
The rule applies whether you’re based in California or just passing through. If your truck operates on California roads and meets those qualifications, you need a Clean Truck Check. That includes out-of-state operators, owner-operators, fleet managers, construction companies, and anyone else running heavy-duty diesel equipment in the state.
Most heavy-duty trucks need to submit a passing Clean Truck Check twice per year—that’s semi-annual testing. Your specific compliance deadlines are tied to your truck’s VIN and show up in CARB’s online system when you register your vehicle in their database.
You can submit a passing test up to 90 days before your deadline, which gives you a buffer to plan around your schedule. If you wait until the last minute and your truck fails, you’re looking at potential registration holds and operational delays.
CARB doesn’t send reminder notices. It’s on you to track your deadlines and make sure passing tests are submitted on time. Miss a deadline and the DMV can block your registration renewal immediately. That means your truck is grounded until you get a passing test on file. The penalty for operating a non-compliant vehicle can reach $10,000 per truck per day, so this isn’t something you want to ignore or push off.
If your truck fails, you don’t pay for the test. We’ll walk you through exactly what caused the failure—usually it’s a check engine light, an emissions system fault, or incomplete readiness monitors in the OBD system.
You’ll need to address whatever triggered the failure before retesting. That might mean fixing a sensor, clearing a fault code, or completing a drive cycle so your truck’s monitors reset. Some failures are quick fixes, others require more involved repairs depending on what’s wrong with the emissions system.
Once the issue is resolved, you can schedule a retest. We’ll come back out, scan the truck again, and if it passes the second time, we submit those results to CARB and you’re compliant. There’s no limit on how many times you can retest, but every day your truck isn’t compliant is a day you’re risking registration holds and penalties. The faster you address the failure and retest, the faster you’re back in business.
Yes. We bring the testing equipment directly to your location anywhere in Inglewood, CA. That means your yard, your job site, a parking lot, wherever your truck is parked and accessible.
Mobile testing exists specifically because heavy-duty truck operators can’t afford to lose half a day driving to a testing station, waiting in line, and driving back. Your truck earns money when it’s moving or working, not when it’s sitting at a smog shop.
We schedule appointments based on your availability and come to you with CARB certified scanning equipment. The test takes about 30 minutes for a passing vehicle, and results get transmitted to CARB electronically on site. If your truck passes, any DMV registration hold clears the same day. You don’t leave your location, you don’t disrupt your operation, and your truck gets back to work as fast as possible.
Testing starts at $79 per truck that passes. If your truck doesn’t pass, you don’t pay. It’s that straightforward.
The no-pass-no-pay structure exists because we’re not interested in charging you for a test that doesn’t solve your compliance problem. If your truck fails, you’re already dealing with downtime and repair costs. Adding a testing fee on top of that doesn’t help anyone.
Pricing can vary slightly depending on your location within Inglewood and how many trucks you need tested at once. Fleet operators testing multiple vehicles at the same location often get better per-truck rates because we’re already on site. But the baseline is simple: you only pay when your truck passes and your compliance issue is resolved. No hidden fees, no charges for failed tests, no surprises on the invoice.
The first compliance testing deadline hit on January 1, 2025. If you’re operating a 2013 or newer heavy-duty diesel truck over 14,000 lbs GVWR in California, you need a passing Clean Truck Check on file with CARB or you risk registration holds and penalties.
After that initial deadline, you’ll have semi-annual testing requirements tied to your specific vehicle. CARB assigns deadlines based on your truck’s VIN, and those dates show up in their online system when you register your vehicle in the Clean Truck Check database.
The enforcement is real. CARB has been using roadside emissions monitoring and automated license plate readers since January 2023 to identify high-emitting vehicles. If your truck is flagged and you’re not compliant, you’re looking at potential fines up to $10,000 per vehicle per day, plus DMV registration blocks that ground your truck until you submit a passing test. The best approach is to stay ahead of your deadlines, submit tests early when possible, and avoid the last-minute scramble that puts your operation at risk.
