Mobile Testing · The Shop Comes To You

CARB Clean Truck Check, in your yard

You already give this program enough money and time. You shouldn't also pull rigs off a job to drive them to a shop. A credentialed tester comes to your yard, terminal, or job site and tests them where they sit — a single tractor or a whole construction fleet, in one visit.

Not sure what's due? Call the owner. Bring your list and we'll tell you what each truck needs — and work around your schedule, not ours.

How mobile testing works

Three steps, one visit

01

Send your fleet list

Give us VINs, plates, and your location. We confirm which trucks are due and which test method each one needs.

02

Pick a time

We schedule around your operation — before dispatch, after the last run, or whenever the trucks are actually parked.

03

We test on site

Testing is completed and submitted at your location. Retesting is included under our standard service policy.

What we test

The whole yard, old trucks and new

Most fleets are a mix — newer tractors next to a 2010 dump truck. One provider can handle eligible OBD vehicles and non-OBD vehicles in the same fleet visit — one company, one invoice, one thing off your plate.

  • 2013-and-newer diesel
  • 2018-and-newer alternative fuel

  • Results submitted electronically after testing

Running a large fleet?

Once you're testing a lot of trucks, the CC40 usually saves money and removes the scheduling entirely — the truck tests itself and automatically submits eligible results to CARB. Call and we'll work out which trucks should be on the device and which stay on mobile.

Why fleets choose A+ Plus

You're calling the owner, not a call center

More than 20 years in automotive repair, smog, emissions, and fleet service — and the person who answers when you call. No call center, no runaround.

Less downtime

Trucks stay in your yard. Testing happens between runs instead of replacing them.

No unnecessary trips

No shop appointments, no driver hours burned sitting in a testing line across town.

Clear communication

You get told what passed, what didn't, and what to do about it. In plain language.

Retesting support

Retesting is included under our standard service policy, so a second pass is already accounted for.

Statewide

Northern and Southern California. If your trucks are parked in this state, we can get to them.

CARB experience

4,000+ tests and a credentialed tester who knows how the program actually runs day to day.

NORTH CA SOUTH CA
Service area

The whole state, not just one city

California statewide service, subject to routing and scheduling availability, with bilingual support for cross-border fleets. Freight yard, construction site, equipment lot, or a single truck at the shop — wherever your diesels are parked in the state, reach out and we'll work out coverage.

Northern California

  • Sacramento Valley
  • Bay Area
  • Central Valley
  • Redding & north
  • Stockton · Modesto

Southern California

  • Los Angeles County
  • Inland Empire
  • Orange County
  • San Diego County

Before we arrive

A little prep keeps the visit quick and avoids a wasted trip. Have the truck accessible, batteries charged, and fuel available, with emissions equipment intact. For OBD vehicles, an unresolved check-engine light, incomplete readiness monitors, or a recent battery disconnection may prevent a passing result. Not sure if a truck is ready? Call us and we'll talk it through before we head out.

Get on the schedule

One call sorts your whole yard

Tell us what you're running — years, VINs, how many. We'll tell you what's due, which trucks the CC40 could take off your plate for good, and set a time. No obligation, no pressure.
