Short answer: yes. Clean Truck Check tests can be performed on-site by a mobile tester. Diesel Dynamix comes to your yard, jobsite, terminal or parking location anywhere in Southern California.

How an on-site visit works

  1. You tell us how many trucks, which engine types and where they are parked.
  2. We confirm a time window that fits your dispatch.
  3. Our tester arrives and runs the right test for each truck: OBD, smoke opacity or visual inspection.
  4. Results are submitted and we explain next steps for every truck.

What we need on site

  • The VIN, keys and cab access for each truck
  • A safe, level spot to work
  • For smoke tests, engines that can reach operating temperature

Why fleets prefer mobile testing

No drivers off the road, no fuel burned driving to a test site, and one visit covers the whole yard. See how testing works or book mobile testing.

Places we test besides your yard

Clean Truck Check can be done on site almost anywhere a truck can safely park. You do not have to take your truck somewhere.

Diesel Dynamix tests trucks at:

  • Your yard or terminal. The most common choice for fleets.
  • Construction sites. Dump trucks, water trucks and mixers tested between loads.
  • Warehouse docks and distribution centers. Test while the truck is being loaded or unloaded.
  • Truck parking lots. Where owner-operators keep their trucks.
  • Truck stops in Southern California. If that is where the truck is resting, tell us the location.
  • Port areas. Near the Port of Los Angeles and Port of Long Beach.
  • Your home. For owner-operators and diesel motorhome owners.

What every location needs is the same: a safe, level spot, access to the truck, keys and the VIN. For smoke tests, the engine has to be able to reach operating temperature. If the site belongs to someone else, make sure we are allowed to work there.
