Fleet Clean Truck Check — LA & Riverside County

Every Truck Certified Before We Leave Your Yard

One visit. All your trucks scanned and submitted to the state database on-site. No shop trips, no repositioning, no driver downtime — fleet Clean Truck Check testing that works around your operation, not the other way around.

Verifiable CARB Credential

Our CARB Tester Credential E164983 is publicly searchable on CARB’s own database — look it up before you call us.

Executive Order-Certified Equipment

We use only CARB Executive Order-certified OBD devices — the standard that makes your test results valid for CTC-VIS submission.

Same-Day CTC-VIS Submission

Results are uploaded to the state database on-site, before we leave. You get confirmation of compliance — not a promise it’ll be filed later.

On-Site Fleet Emissions Testing — LA & Riverside County

Built for Fleets Running the I-10 and I-710 Corridors

If you’re running a fleet out of Long Beach, Pomona, Perris, or anywhere along the Inland Empire logistics belt, you already know that pulling trucks off the route isn’t a minor inconvenience — it’s lost revenue. Every hour a driver sits waiting at a shop is an hour that truck isn’t earning. That’s the problem on-site fleet Clean Truck Check testing was built to solve. We come to your yard, your job site, or wherever your trucks are parked. Each OBD scan takes roughly 10 to 15 minutes per truck. We connect directly to the ECU, download the exact emissions data California requires, and submit it to CARB’s CTC-VIS database before we drive away. Whether you’re running 5 trucks or 50, one visit handles it all — and every truck leaves with its compliance confirmed, not pending.

Mobile Fleet CARB Testing — What You Actually Get

One Visit. Zero Disruption. Full Fleet Certified.

Here's what changes when your fleet testing comes to you instead of the other way around.

Every truck’s CTC-VIS submission is complete and confirmed before we leave your yard — no waiting, no follow-up calls.

Your drivers stay on schedule because there’s no shop trip, no wait time, and no truck pulled from active rotation.

Volume pricing applies for fleets of 5 or more trucks, so the per-truck cost goes down the more you schedule at once.

You can schedule testing up to 90 days before your compliance deadline, locking in your fleet’s entire testing calendar in one planning call.

Emergency compliance support is available for trucks sitting on DMV registration holds or under a Notice to Submit to Testing with a 30-day clock running.

Freight brokers and shippers increasingly require compliance documentation before dispatching — our same-day CTC-VIS submission gives you that proof immediately.

Yard Testing Heavy-Duty Trucks — LA & Riverside County

A Specialist Is Not the Same as a Generalist

There are providers in the LA and Riverside County market who list Clean Truck Check as one item on a long menu of services — right next to oil changes, DOT inspections, and general smog checks. That’s not what we do. Every piece of equipment we carry, every credential we hold, and every protocol we know is calibrated specifically to HD I/M OBD testing for Class 6, 7, and 8 trucks. We work with J1939 and J1979 OBD protocols — the truck-specific communication standards that a general smog station’s equipment typically isn’t set up to handle correctly. When a test is submitted through a non-certified device or by an uncredentialed tester, the result can be rejected by CTC-VIS — leaving your truck technically non-compliant despite having paid for the test. Our credential — E164983 — is on CARB’s public database right now. We invite you to look it up before you schedule anything.

Bulk Clean Truck Check — Volume Scheduling for Fleets

The 2027 Quarterly Mandate Is Closer Than It Looks

Right now, most fleets are required to submit Clean Truck Check tests twice a year. Starting October 1, 2027, OBD-equipped trucks move to four times per year. For a fleet of 20 trucks, that’s 80 compliance events annually instead of 40. Fleet managers in LA and Riverside County who don’t have a reliable, on-site testing relationship established before that mandate kicks in are going to feel it — especially in a market where the demand for credentialed testers is concentrated and growing fast. The time to build that relationship is now, not in 2026 when the scheduling backlog starts. One call gets your fleet mapped out. We’ll help you identify each truck’s deadline window, schedule testing visits around your dispatch calendar, and make sure nothing slips through. Whether your trucks are staged in Perris, running drayage out of Long Beach, or hauling freight along SR-60 and I-215, we cover the ground where your fleet actually operates.

Frequently Asked Questions

Can you test all of our trucks in one visit at our yard?

Yes — that’s exactly how our fleet service is structured. We come to your location, whether that’s a yard in Perris, a distribution facility off I-215, or a staging area near the Port of Long Beach, and work through your trucks one by one. Each OBD scan takes roughly 10 to 15 minutes per vehicle. We connect to the truck’s ECU, pull the emissions data, and submit the result directly to CARB’s CTC-VIS database before moving to the next truck. By the time we leave your yard, every truck that passed has a confirmed compliance record in the state system — not a pending submission.

What trucks are actually required to get Clean Truck Check testing in California?

The program covers diesel-powered trucks with a model year of 2013 or newer and a Gross Vehicle Weight Rating over 14,000 pounds. It also covers alternative fuel trucks with a model year of 2018 or newer at the same GVWR threshold. If your truck has an OBD-compliant system and falls into those categories, it needs periodic testing — regardless of whether it’s registered in California or another state. Out-of-state trucks operating in LA and Riverside County are subject to the same requirements. If you’re not sure whether a specific truck in your fleet qualifies, call us and we’ll tell you straight.

How often does each truck in our fleet need to be tested?

Currently, most non-agricultural fleets are required to submit tests twice per year — semi-annually. That’s the schedule in effect right now for the LA and Riverside County market. However, starting October 1, 2027, OBD-equipped trucks move to four times per year. That’s a significant increase, and it affects your planning now. A fleet of 15 trucks that currently needs 30 compliance events per year will need 60 starting in 2027. Fleets that build a testing relationship with a reliable on-site provider before that mandate takes effect will be in a much better position than those who scramble to find availability when the demand spike hits.

What happens if one of our trucks receives a Notice to Submit to Testing from CARB?

A Notice to Submit to Testing — NST — means CARB has flagged that vehicle as a potential high emitter, often through roadside sensor data collected on corridors like the I-710 or I-10. Once you receive an NST, you have 30 calendar days to submit a passing emissions test from a CARB-credentialed tester. That’s a short window, especially if you’re trying to coordinate around an active dispatch schedule. We offer emergency compliance support specifically for this situation. Call or text us directly — we don’t route you through a call center — and we’ll work to get your truck tested and submitted as quickly as possible.

How do we know the test results will actually be accepted by the state?

This is one of the most important questions a fleet manager can ask, and not enough people ask it before they book. For a Clean Truck Check result to be valid, two things have to be true: the tester must hold a current CARB credential, and the OBD device used must have received a CARB Executive Order under Title 13 of the California Code of Regulations. Our credential — E164983 — is publicly searchable on CARB’s credentialed tester database right now. We also use only CARB Executive Order-certified OBD equipment. When we submit a result to CTC-VIS, it counts. That’s not something every provider in the LA and Riverside County market can say with a verifiable credential number to back it up.

Is there a discount for testing multiple trucks at once?

Yes. We offer volume pricing for fleets of five or more trucks. The per-truck cost goes down when you schedule as a fleet rather than booking individual appointments over time. Beyond the pricing, there’s a practical efficiency argument too: one visit, one coordination effort, one block of time on your operations calendar instead of multiple scheduling events spread across weeks. If you’re managing a fleet in Riverside County, the Inland Empire logistics corridor, or anywhere in Los Angeles County, call or text us to get a custom fleet quote. We’ll confirm availability and pricing within the hour — no corporate red tape, no hold music.
