You’re not dealing with registration holds at the DMV. You’re not scrambling to explain to your dispatcher why a truck is sidelined. And you’re definitely not writing checks for $1,000+ per day, per vehicle in fines because CARB flagged your fleet.
When your trucks pass their Clean Truck Check, CARB transmits your compliant VIN to the DMV that same night. Your registration stays clean. Your operation stays moving. Your liability drops to zero on this front.
This isn’t about checking a box. It’s about protecting your business from enforcement action that can cost you more in a week than you’ll spend on compliance all year. If your trucks are model year 2013 or newer with a GVWR over 14,000 pounds, this test isn’t optional anymore—it’s required, and the deadlines started January 1, 2025.
We’ve been handling emissions testing in Santa Monica for years. We’ve seen every version of California’s air quality regulations, and we’ve helped local fleets, owner-operators, and commercial drivers stay ahead of them.
Now that CARB’s Heavy-Duty Inspection and Maintenance program is in full enforcement, we’re equipped with certified OBD testing devices and our team has completed CARB’s credentialed tester training. We know what the state requires, and we know how to get your trucks through without the runaround.
Santa Monica sits right in the heart of LA County’s logistics corridor. Your trucks move through here, and when they need compliance testing, you need a shop that’s fast, local, and knows exactly what CARB is looking for.
You schedule your appointment or pull in during business hours. We’ll verify your truck qualifies—meaning it’s a 2013 or newer model with a GVWR over 14,000 pounds. If it’s OBD-equipped, we’re scanning the engine’s onboard diagnostics using a CARB-approved device.
The test itself takes 15 to 30 minutes. We’re checking emissions data, running it through CARB’s compliance standards, and generating your results on the spot. If your truck passes, we submit that passing test directly to CARB. They update your VIN status in their system, and the DMV gets notified that night.
If something comes back flagged, we’ll walk you through what needs attention. You’ll know exactly what the issue is and what it takes to fix it before you retest. No surprises, no vague explanations.
You can submit a passing test up to 90 days before your compliance deadline, so if your truck’s due February 1st, you’re clear to test as early as November. That window gives you time to handle repairs if needed and retest without cutting it close.

This is CARB-mandated emissions compliance testing for heavy-duty trucks. If your vehicle is a 2013 or newer diesel, or a 2018 or newer alternative fuel truck, and it’s over 14,000 pounds GVWR, this applies to you.
We’re running a full OBD scan using state-certified equipment. That means we’re pulling data directly from your truck’s engine computer—checking for emissions performance, fault codes, and anything that would flag you as non-compliant under CARB’s HD I/M program.
In Santa Monica and across California, enforcement is active. The DMV has already started placing registration holds on non-compliant vehicles as of August 2024. CARB’s not issuing warnings anymore—they’re issuing fines. And those fines can hit $10,000 per vehicle per day if you’re operating out of compliance.
This service keeps you off that list. It’s fast, it’s local, and it’s handled by testers who’ve been trained and credentialed by CARB. You’re not guessing whether the test will hold up—you’re getting results that go straight into the state’s system.
If your truck is model year 2013 or newer and has a gross vehicle weight rating over 14,000 pounds, yes—you need this test. That includes diesel trucks from 2013 forward and alternative fuel trucks from 2018 forward, as long as they’re OBD-equipped.
This isn’t a smog check for light-duty vehicles. It’s a separate program called Heavy-Duty Inspection and Maintenance, or HD I/M, and it’s enforced by CARB. The first compliance deadline hit January 1, 2025, and the DMV is already blocking registrations for trucks that haven’t passed.
If you’re not sure whether your truck qualifies, bring in your registration or VIN. We can check CARB’s database and tell you right away whether you’re subject to the program and when your next deadline is.
CARB will flag your VIN as non-compliant, and the DMV will place a hold on your registration. That means you can’t renew, and if you’re caught operating the vehicle, you’re looking at fines that start at $1,000 per day per vehicle—and can go as high as $10,000 depending on the violation.
Registration holds aren’t warnings. They’re enforcement actions, and they’re already happening. CARB transmits updated compliance lists to the DMV every night, so once you’re flagged, it shows up fast.
The other risk is operational. If your truck can’t be registered, it can’t legally operate in California. That’s downtime, lost revenue, and a scramble to get compliant after the fact. It’s a lot easier to stay ahead of the deadline than to dig out from under a hold.
Most trucks are in and out in 15 to 30 minutes. That includes parking, paperwork, the OBD scan, and payment. We’re not tearing anything apart—we’re plugging into your truck’s diagnostic port and pulling emissions data.
If your truck passes, we submit the results to CARB right away. You’ll get confirmation, and CARB updates your compliance status in their system that same day. The DMV gets notified overnight.
If something flags during the test, we’ll explain what the issue is before you leave. You’re not walking out confused. You’ll know what needs to be fixed and whether it’s something you can handle on your own or if it needs a shop. Once it’s repaired, you can come back and retest.
You can test up to 90 days before your deadline. So if your truck’s compliance date is March 1st, you’re good to come in as early as December 1st. CARB allows early testing specifically so you have time to address any issues without cutting it close.
Testing early is smart if you’re running a tight schedule or if your truck’s older and you’re not sure how it’ll perform. If it passes, you’re done. If it doesn’t, you’ve got a buffer to make repairs and retest before the deadline hits.
Once you pass, that test is valid for your compliance period. You don’t need to retest unless CARB flags your truck again or your next deadline rolls around. Each truck has its own schedule based on VIN and registration, so it’s worth checking CARB’s CTC-VIS database to confirm your exact date.
A regular smog check is for light-duty vehicles—cars, SUVs, and smaller trucks under 14,000 pounds. A Clean Truck Check is for heavy-duty vehicles over 14,000 pounds GVWR, and it’s part of CARB’s HD I/M program, not the standard smog program.
The equipment is different. For Clean Truck Checks, we’re using CARB-certified OBD devices that scan your truck’s engine computer for emissions performance data. The test criteria are stricter, and the results go directly into CARB’s Heavy-Duty Compliance system, not the DMV’s smog database.
You can’t use a regular smog check to satisfy your Clean Truck Check requirement. They’re separate programs with separate deadlines, and CARB enforces them differently. If your truck is over 14,000 pounds and 2013 or newer, you need the HD I/M test—not a standard smog test.
CARB charges a $31 annual program fee per vehicle, and that goes directly to the state. The testing fee varies by shop, but you’re typically looking at a reasonable cost for the OBD scan and compliance submission.
What costs more is not getting tested. Fines for non-compliance start at $1,000 per day per vehicle and can climb to $10,000 depending on how long you’re out of compliance and whether CARB considers it a repeat violation. Add in registration holds, potential impound fees, and lost revenue from downtime, and the math gets ugly fast.
Testing is a known cost you can plan for. Fines and enforcement actions aren’t. If you’re running a fleet, budgeting for annual compliance is a lot smarter than gambling on whether CARB will catch you. They will.
