Serving fleets since July 2025 from our Otay Mesa base — Clean Truck Check, diesel smog checks and emissions testing delivered to your yard in San Diego, Chula Vista, El Cajon, Poway, Oceanside, Escondido and every surrounding city.
Fleet Emissions Solutions exists to make California emissions compliance painless for the people who move freight. Instead of pulling a rig off dispatch for half a day, our credentialed technicians drive to you, complete the inspection, and file the result — so your only job is keeping the wheels turning.
Dedicated solely to medium and heavy-duty commercial operations.
We dispatch to your yard, saving towing costs and driver downtime.
We dispatch to your yard or job site anywhere in San Diego County, so trucks never leave the schedule to sit in a shop queue.
CARB testing requirementsCredentialed HD I/M testers, licensed and insured. Passing results are filed directly into the CARB Clean Truck Check database the same day.
CARB compliance deadlinesOpen 24/7 and scheduled around your operation — nights and weekends included — because every idle hour is lost revenue.
We do not just test. We diagnose and clean the EGR, DPF and intake systems that cause failures in the first place.
EPA DPF basicsAccurate CARB reporting, transparent pricing from $150, and a satisfaction guarantee on every inspection we perform.
California's Clean Truck Check program requires periodic emissions testing for nearly all non-gasoline vehicles over 14,000 lbs GVWR. We run OBD and opacity testing at your yard and transmit passing results straight to the state.
Diesel smog checks for trucks, RVs, box trucks and out-of-state vehicles operating in California. Includes pre-test smog inspection, retest smog inspection and emission waiver assistance if a unit fails.
A deep clean of the EGR circuit, DPF and intake system that dissolves carbon buildup and restores power and fuel economy — typically far cheaper than replacing a clogged diesel particulate filter.
Onsite emission system diagnostics and check engine light diagnostics. We read live data, pinpoint the fault code and tell you exactly what it takes to pass your next smog test.
Annual DOT inspections and 90-day BIT inspections performed at your yard so drivers stay on the road. We document everything you need for a roadside stop or a CHP terminal audit.
Mobile interior vacuum, cab wipe down and exterior wash. A clean truck reflects your brand at every delivery and keeps drivers comfortable on long hauls.

Our mobile Clean Truck Check (HD I/M) starts at $150 per vehicle. Because we operate as a fully mobile smog inspection station, that price includes credentialed HD I/M emissions testing performed at your yard anywhere in San Diego County — no towing, no shop wait time.
CARB requires most non-gasoline vehicles over 14,000 lbs GVWR to be tested periodically, moving to a biannual (twice-yearly) compliance schedule as the program phases in. We track your due dates and submit passing results to CARB for you.
Yes. We perform diesel smog checks and emissions testing for RVs, motorhomes, box trucks, and all heavy-duty non-gasoline vehicles over 14,000 lbs GVWR so you stay compliant with CARB regulations.

Yes. If a truck fails, we walk fleet managers and owner-operators through the retest smog inspection process, repair documentation, and emission waiver assistance so your equipment keeps working while the issue is resolved.
We handle out-of-state vehicle emission testing for trucks operating in California, plus older vehicle smog testing using opacity (smoke) testing for pre-2013 engines that are not OBD-equipped.
Diesel Force (starting at $1,500) is a deep cleaning of the EGR circuit, DPF, and intake system that removes carbon buildup and restores lost power and fuel economy — often avoiding a costly DPF or EGR replacement.
Location-specific answers for fleets in Otay Mesa, the South Bay, and across San Diego County.
We are based at 7210 Otay Mesa Rd, San Diego, CA 92154, in the Otay Mesa neighborhood — minutes from the Otay Mesa commercial port of entry and the SR-905 / I-805 freight corridor. Because we run a fully mobile smog inspection station, you do not drive to us; we drive to your yard.
Yes. Chula Vista, National City, Imperial Beach, Lincoln Acres, Lemon Grove, and Otay Mesa are all in our core South Bay coverage area, typically reached the same day from our Otay Mesa base. We test at your yard, terminal, or job site so trucks never leave dispatch.
We routinely travel throughout San Diego County, including Escondido, Oceanside, Poway, Del Mar, Ramona, Santee, Lakeside, El Cajon, La Mesa, Bonita, Jamul, and Coronado. We also serve Imperial County border communities such as Calexico and Tecate for scheduled fleet visits.
Yes. Cross-border carriers operating in California must meet the CARB Clean Truck Check (HD I/M) requirement, and non-California-registered trucks are subject to the program when they operate in the state. Our Otay Mesa location lets us test drayage and cross-border fleets close to the port of entry, and our team assists in English and Spanish.
Mobile Clean Truck Check pricing starts at $150 per vehicle and includes travel within our San Diego County service area. For long-distance or out-of-county requests, we confirm any additional travel cost in writing before we schedule the visit.
We schedule 24 hours a day, seven days a week, and South Bay and central San Diego locations can often be covered same day or next day. Multi-truck fleet visits are batched into a single appointment so an entire yard is tested and filed with CARB in one stop.
No. Heavy-duty vehicles over 14,000 lbs GVWR are covered by CARB's Clean Truck Check program rather than the BAR smog check station network, and our credentialed testers submit passing OBD and opacity results directly to the CARB database from your San Diego job site.
A missing Clean Truck Check compliance record can block DMV registration for affected vehicles. We test the vehicle, submit the passing result to CARB, and provide documentation you can use to clear the compliance record — plus retest and repair guidance if a truck fails.
