This site is part of a market-testing lab for mobile CARB Clean Truck Check demand. It is intentionally not branded as norcalcarbmobile.com.

## How much does mobile CARB testing cost in Lodi?
Current market test pricing is $119 for HD-OBD testing and $219 for OVI smoke or opacity testing. Market test pricing for Lodi-area fleets. Same-yard multi-truck scheduling is prioritized.

## Do you come to our yard or job site?
Yes. Mobile CARB Testing is built around mobile appointments at fleet yards, warehouses, contractor lots, farms, and job sites across San Joaquin County.

## What information should I have ready before scheduling?
Have the truck VIN, license plate, engine year if known, odometer or hour meter, contact name, site address, and whether the truck is 2013 or newer for HD-OBD or 2012 and older for OVI smoke testing.

## Can you help explain what test my truck needs?
Yes. The intake form asks a few routing questions so dispatch can recommend the right appointment type and avoid sending the wrong equipment.

## Is this connected to NorCal CARB Mobile?
No. This market page is branded as Mobile CARB Testing so pricing, city intent, and service-area demand can be tested independently.

## What is the difference between HD-OBD and OVI smoke testing?
HD-OBD testing reads supported onboard diagnostic data, commonly for 2013 and newer diesel trucks. OVI smoke or opacity testing is used for older diesel equipment that needs a visible emissions opacity check.

## Can one appointment cover multiple trucks?
Yes. Multiple trucks at the same yard are preferred because they reduce travel time and make pricing experiments in Lodi easier to compare against broader hub pages.

## What happens if a truck is not ready when the technician arrives?
Dispatch asks for site details ahead of time so trucks can be parked, accessible, warmed up if needed, and ready for the right test type.

## Why does this site publish pricing?
Published pricing is part of the market test. It helps measure whether clear local pricing increases qualified calls, reduces repetitive questions, and improves AI search answer quality.
