We're based in Perris — the geographic center of Riverside County — and we cover every corridor from the I-215 warehouse district to the Coachella Valley. This page walks through exactly where we go and how the whole Clean Truck Check process works.
Most mobile Clean Truck Check providers serving Riverside County are driving here from somewhere else — LA, Orange County, San Diego, or San Bernardino. That matters more than it sounds. When your tester is dispatching from 60 miles away, you're paying for that drive, waiting longer for a confirmation, and working with someone who treats Riverside County as a destination rather than a home base.
We're based at 425 W. Rider St. in Perris — right in the middle of the county. The Ramona Expressway, the I-215 corridor, the SR-60 warehouse district — that's our backyard, not a service area we added to a map. When you call us, you're not the last stop on a long route from the west side.
That geographic reality translates to concrete things: faster scheduling, lower travel fees for most of Riverside County, and a tester who already knows the staging areas, the distribution yards, and the freight corridors you're running every day. We've built this business specifically around Riverside County operators — the fleets running out of Moreno Valley's World Logistics Center, the owner-operators on the I-215, the ag haulers coming out of the Coachella Valley during harvest season. This is the market we know, and it shows in how we work.
Pricing is simple: the mobile inspection is $150 per truck, plus a travel fee confirmed at booking based on your location. We test single trucks and full fleets — for larger yards, we test everything on-site and handle all submissions in one visit, so there's no coordinating multiple appointments or sending trucks to a station.
We're CARB-credentialed — Tester E164983, publicly searchable on arb.ca.gov before you ever call us. We use CARB-approved OBD testing devices, not generic scanners. When the test is done, results go directly into CARB's CTC-VIS system in real time. You don't upload test results or wait on paperwork — we submit them for you, and the compliance record is there the moment we're finished.
One thing worth clearing up: the annual CARB compliance fee — $32.13 per vehicle for 2026 — is separate from the cost of the emissions test itself. A lot of operators pay that fee, assume they're done, and then hit a DMV registration hold at renewal because no passing test result was ever submitted. The fee and the test are two different requirements. We handle the test; you handle the fee through the CTC-VIS portal. Both have to happen.
If you've received a Notice to Submit to Testing, you have 30 days from the date on that letter to submit a passing result. Call or text and you'll hear back fast — the owner answers his own phone. Not sure when your truck is due? Use our CARB deadline calculator to check in seconds.
Starting October 1, 2027, the testing frequency increases from semi-annual to quarterly. That's four tests per truck per year instead of two. Operators who already have a reliable local tester in place will barely notice the change. Operators who scramble to find someone every 90 days starting in late 2027 will feel it. Now is a reasonable time to establish a process that works.
This is the core of our service area and the highest-density diesel freight zone in Riverside County. The I-215 runs straight through it, feeding the World Logistics Center in Moreno Valley, the distribution clusters along the Ramona Expressway in Perris, and the major Amazon, Ross Stores, and Home Depot operations that move trucks in and out daily. CARB's roadside emissions monitoring devices are deployed along corridors exactly like this one — which means trucks running the I-215 are being screened regularly. A flagged truck gets a Notice to Submit to Testing and a 30-day clock. We're already in this corridor. We know the yards, the staging areas, and the operators. If you're running freight out of this part of Riverside County, we're the closest credentialed tester you're going to find. For deadlines specific to this county, see our Riverside County CARB compliance timeline guide.
The I-15 corridor through Temecula and Murrieta is one of the fastest-growing commercial zones in Southern California, and the I-15/I-215 interchange at Murrieta is a major transition point for freight moving between San Diego County and the Inland Empire. Commercial fleets operating along Clinton Keith Road, the SR-79 corridor toward Hemet, and the expanding industrial zones in Wildomar and French Valley all fall within our regular service area. Temecula and Murrieta aren't a long-distance reach for us — they're local.
The San Jacinto Valley is more rural and, frankly, underserved by most mobile testing providers. Operators in Hemet and San Jacinto running trucks on SR-74 toward Perris or SR-79 toward Temecula often have a hard time finding a tester willing to make the drive. We cover this corridor. If your truck is in Hemet, East Hemet, Valle Vista, or San Jacinto, we can get to you — contact us for current travel fee information for this area.
The eastern end of Riverside County runs a different kind of trucking economy. The I-10 through the Coachella Valley carries agricultural freight — dates, citrus, table grapes, vegetables — especially during harvest season from fall through spring. Ag haulers operating diesel trucks that meet the model year and GVWR thresholds are subject to Clean Truck Check, and many seasonal operators aren't aware of that until they get a notice. We cover the Coachella Valley, including Indio and Palm Desert. Travel fees for this area are quoted at booking, but we make the trip regularly. If you're running harvest freight out of Indio or Coachella and you're not sure whether your trucks qualify, call us — we'll tell you straight.
Yes. We cover Indio, Palm Springs, Thousand Palms, Coachella, and the surrounding eastern Riverside County area. Because it's a longer drive from Perris, we quote a travel fee at booking based on your specific location. We make the trip regularly — especially during harvest season when ag haulers need testing and most providers won't make the drive out to the Coachella Valley.
They're two separate things, and confusing them is the most common mistake we see. The annual CARB compliance fee — $32.13 per vehicle for 2026 — is paid by the vehicle owner through the CTC-VIS portal. It does not satisfy the emissions testing requirement. The test is a separate step: a CARB-credentialed tester uses approved OBD equipment to scan your truck, and the result is submitted electronically to CARB's system. Our test is $150 per truck, plus travel fee. Both the fee and the passing test result have to be on file for your truck to be considered compliant. Paying one without the other leaves you with a DMV registration hold.
Look us up before you call. Our credential is Tester E164983, publicly listed on CARB's tester database at arb.ca.gov. Our tester completed CARB's official HD I/M Tester Training Course, passed the required exam, and holds a state-issued credential — and this is an owner-operated business, so the credentialed tester is who shows up at your yard. We invite you to verify it independently — you shouldn't have to take anyone's word for it.
We cover all of Riverside County, from the I-215 freight corridor in the west to the Coachella Valley in the east — travel fees vary by distance and are confirmed at booking.
