Mobile CARB testing for Roseville

Roseville’s mix of active construction, logistics, and residential affluence means plenty of heavy-duty diesel equipment that falls under the CARB Clean Truck Check program. From grading contractors with yards near Highway 65 to owner-operators parking at home in Fiddyment Farm to RV owners along the Galleria corridor, we bring certified mobile testing to all of them.

Where we dispatch in Roseville

We regularly serve the Atlantic Street and Washington Boulevard industrial corridors, Fiddyment Farm business areas, the Railyard district, Highway 65 commercial addresses, and residential neighborhoods throughout East Roseville, West Roseville, and the Galleria area.

Contractor and construction fleets

Roseville is one of the most active construction markets in the Sacramento region, and the grading, paving, and general contractor fleets that feed that activity run a lot of heavy-duty diesel equipment. Our mobile service handles your full CARB Clean Truck Check compliance cycle without pulling trucks off job sites.

RV owners

Heavy-duty motorhomes in Roseville storage lots or on residential driveways are subject to Clean Truck Check if they are over 14,000 lbs GVWR. We test at the coach’s current location, whether that is a storage yard, RV park, or home address. Pass results upload electronically the same day on OBD tests.

Frequently asked questions

Do you test at residential addresses in Roseville?
Yes, regularly. Roseville residential testing is common for owner-operators and RV owners. Just let us know the address and any gate or HOA procedures when you book.
How does Roseville compare to Sacramento for response time?
Roseville is about 25 to 30 minutes from our Sacramento dispatch. Most appointments are scheduled within 24 hours and we often handle same-day urgent calls.
Can a contractor fleet be tested at its Roseville yard?
Absolutely. We routinely test construction, paving, and grading fleets at their Roseville yards and staging areas. Schedule the visit and we will cycle through your rigs efficiently.
Does my Roseville truck need an OBD or OVI test?
It depends on your engine model year. Diesel engines from 2013 and newer take the electronic OBD test, and 2012 and older engines take the OVI smoke opacity and visual inspection. We are credentialed for both and bring the right equipment based on the engines you tell us about when booking your Roseville visit.
How much does CARB Clean Truck Check testing cost in Roseville?
There are two parts. CARB charges an annual compliance fee of $32.13 per vehicle in 2026, paid to the state. Separately, you pay for the test itself, which depends on the test type and vehicle count. Mobile pricing is consistent across our coverage area, and fleets scheduling several trucks in one visit qualify for volume rates. Call (916) 538-7777 for a quote.
How fast does a Roseville test clear my DMV registration hold?
For 2013 and newer engines passing the OBD test, we upload results during the visit and CARB releases compliance to the DMV the same business day in most cases, so a Roseville-registered rig can come off its hold within hours. OVI results take several business days for CARB to process.
What happens if my Roseville truck fails the test?
A failed test carries no fine by itself, but your DMV hold stays until you repair the issue and pass a retest. We tell you exactly what failed, point you to the specific OBD trouble code or OVI finding, and can recommend trusted diesel repair shops in the Roseville and Placer County area. Once the fix is done, we come back and retest.
Are you actually CARB credentialed?
Yes. We are credentialed by the California Air Resources Board for both OBD testing and OVI opacity testing, and our credentials are verifiable on the CARB Clean Truck Check program registry. We provide credential numbers on request before any service visit.
