You’re not dealing with DMV registration blocks. You’re not scrambling to fix a compliance issue the day before your deadline. And you’re definitely not paying $1,000-a-day fines because someone missed a test window.
When your 2013 or newer trucks with a GVWR over 14,000 pounds pass their Clean Truck Check, you get documentation filed directly with CARB. That means your fleet stays legal, your registrations go through without a hitch, and your trucks stay on the road doing what they’re supposed to do—making you money.
The testing window gives you up to 90 days before your compliance deadline to submit a passing test. That’s enough time to handle repairs if something comes up, without the panic of a last-minute failure. You also avoid the operational mess that comes with pulling trucks out of service for hours at a time, which can cost you anywhere from $300 to $900 per vehicle in lost productivity.
We’ve been serving Riverside County for years, and we’ve built our reputation on understanding what fleet operators and owner-operators actually need. We’re not just running tests—we’re CARB-credentialed testers who’ve completed the required training and passed the exam with the scores CARB demands.
Nuevo sits right in the heart of California’s logistics corridor, which means you’re dealing with tight schedules, high mileage, and constant pressure to stay compliant. We get it because we see it every day. Our focus is on getting your heavy-duty vehicles tested correctly the first time, so you’re not dealing with retests, paperwork delays, or compliance headaches that pull you away from running your business.
You schedule your Clean Truck Check appointment, and you bring in your 2013 or newer truck that weighs over 14,000 pounds GVWR. We’re testing diesel trucks, alternative fuel trucks, hybrids—basically any heavy-duty vehicle that falls under California’s CARB HD I/M requirements.
The test itself checks your truck’s emissions systems to make sure everything is functioning within CARB’s limits. We’re looking at your onboard diagnostics, exhaust output, and system performance. If your truck passes, we file the results electronically with CARB right away. You get your documentation, and you’re done.
If something doesn’t pass, we’ll tell you exactly what needs attention. Because you have that 90-day window before your deadline, you’ve got time to make repairs and come back for a retest without risking penalties or registration issues. The whole process is designed to keep you ahead of your compliance deadlines, not chasing them.
Ready to get started?
You’re getting a compliance test from a CARB-credentialed tester who knows the regulations that went into effect October 1, 2024. That’s not a small detail—only credentialed testers can submit results that CARB will accept for your compliance deadline.
The test covers emissions compliance for trucks with model year 2013 or newer engines and a GVWR over 14,000 pounds. This applies whether you’re running a single truck or managing an entire fleet. If you receive a Notice to Submit to Testing from CARB, you’ve got 30 days to get a passing test submitted, and we can handle that turnaround.
Starting in 2025, some vehicles will need semi-annual testing—that’s every six months. And by October 2027, if your truck has onboard diagnostics, you’ll be looking at testing four times a year. Riverside County has one of the highest concentrations of commercial trucking in California, which means enforcement is active and penalties are real. The annual compliance fee is $31.18 per vehicle, but the cost of non-compliance can hit $1,000 per vehicle per day—or up to $10,000 for fleet violations.
No. The Clean Truck Check requirement only applies to trucks with model year 2013 or newer engines and a gross vehicle weight rating over 14,000 pounds.
If your truck is older than 2013 or weighs less than 14,000 pounds GVWR, this regulation doesn’t apply to you. CARB designed this program specifically for newer heavy-duty diesel and alternative fuel vehicles, including hybrids and buses. That includes commercial fleets, privately-owned trucks, government vehicles, and even trucks registered outside California if they operate here. If you’re not sure whether your truck qualifies, check your registration or give us a call—we can tell you in about 30 seconds.
You can submit a passing Clean Truck Check test up to 90 days before your compliance deadline.
That window exists so you have time to address any issues if your truck doesn’t pass on the first try. If you wait until the last minute and something fails, you’re looking at potential penalties, registration blocks, or having to pull your truck out of service while you scramble for repairs. Most fleet operators we work with schedule their tests 60 to 75 days out—it gives them a cushion without letting the deadline sneak up on them. Once we file your passing test with CARB, it’s logged electronically and you’re covered.
If your truck fails, we’ll give you a detailed report of what didn’t pass and what needs to be repaired.
You’ll need to get those repairs done, then bring the truck back for a retest. Because you have up to 90 days before your compliance deadline, a failure doesn’t automatically mean penalties—as long as you handle it within that window. The most common failures involve issues with the diesel particulate filter, exhaust sensors, or onboard diagnostic systems. Once the repairs are completed and your truck passes the retest, we file the passing results with CARB and you’re back in compliance. The key is not waiting until the last week to test, because that’s when a failure becomes a real problem.
If your truck meets the requirements—2013 or newer, over 14,000 pounds GVWR—then yes, you need to comply with the Clean Truck Check program regardless of when you registered.
CARB’s compliance deadlines are based on your vehicle’s specific schedule, not your registration date. Some trucks are on an annual testing cycle, and starting in 2025, certain vehicles will be required to test every six months. By 2027, trucks with onboard diagnostics will need testing four times a year. If you recently registered and haven’t received a compliance notice yet, you will. It’s better to get ahead of it than wait for CARB to send you a Notice to Submit to Testing, which only gives you 30 days to comply.
You need to go to a facility with a CARB-credentialed tester—not every smog shop is certified to perform Clean Truck Check testing.
CARB requires testers to complete specific training and pass an exam before they’re allowed to submit compliance test results. If you go somewhere that isn’t credentialed, the test won’t count and you’ll have wasted time and money. We’re a CARB-credentialed testing location in Nuevo, which means the results we file go directly into CARB’s system and satisfy your compliance requirement. You can verify a tester’s credentials through CARB’s website if you’re ever unsure, but the safest move is to call ahead and confirm before you bring your truck in.
Testing costs vary depending on the provider, but most credentialed facilities in the area charge between $50 and $75 per truck.
That might sound like an expense you’d rather skip, but compare it to the alternative: CARB fines start at $1,000 per vehicle per day for non-compliance, and fleet violations can go up to $10,000 per vehicle per day. Add in the cost of a registration block—which can keep your truck off the road indefinitely—and the test fee starts to look pretty reasonable. If you’re running multiple trucks, some facilities offer fleet pricing or volume discounts. The annual compliance fee CARB charges is $31.18 per vehicle, and that’s separate from the testing cost. Bottom line: paying for the test now is a lot cheaper than paying penalties later.
