When deadlines loom, finding an immediate testing solution becomes crucial. Our mobile service resolves CARB compliance hurdles quickly without interrupting your delivery routes.Situated near major commercial hubs, South Whittier operators regularly haul goods through the industrial corridors of nearby Whittier, move freight across La Mirada, or connect to regional routes via Norwalk.

We outline all costs clearly upfront: our $150 per-truck rate plus a location-specific travel fee confirmed at booking.On test day, we travel directly to your preferred site, whether that is a parking yard off Carmenita Road or a staging lot near the freeway. We attach state-approved diagnostic tools to your truck’s OBD port and read sensor data directly from the engine control unit. The testing procedure takes just 10 to 15 minutes per vehicle, requiring no complex preparation or driving.Once finished, we upload your test files directly into CARB’s CTC-VIS database that same day.

California’s Clean Truck Check applies to heavy-duty diesel vehicles model year 2013 or newer rated above 14,000 lbs GVWR operating on California roads. For California-registered trucks the program is fully enforceable; for out-of-state trucks, see the FAQ below – the rules shifted in 2026, but CARB continues enforcing under state law.Vehicles currently undergo testing twice annually, tied to their DMV renewal dates. Starting in October 2027, CARB will transition this requirement to a quarterly schedule, increasing testing to four times per year. All tests must be submitted within 90 days of the compliance deadline. Not sure when yours is due? Use our CARB deadline calculator.Understanding the fee structure is straightforward. Our service charge is $150 per truck plus travel. Separately, CARB assesses an annual $32.13 state compliance fee per vehicle. This state fee is paid directly by the owner through the CTC-VIS portal, it is not part of our testing charge. If you have received a 30-day Notice to Submit to Testing (NST), we offer priority scheduling. Veterans and active military personnel receive a 10 percent discount.

Mostly yes – but this changed in 2026, so here’s the honest picture. In January 2026, EPA disapproved the part of Clean Truck Check that applies to out-of-state-registered trucks, and federal enforcement won’t happen on those vehicles. CARB, however, has said it will keep enforcing the program under state law on all trucks operating in California – and its roadside monitoring doesn’t check your registration state before flagging you. California-registered trucks are unaffected: fully enforceable, DMV holds and all.Out-of-state vehicles follow a deadline schedule based on the final digit of their VIN. If you’re hauling through South Whittier on out-of-state plates and aren’t sure where you stand, call us and we’ll talk it through.
If the check engine light is caused by an active fault in the emissions control system, such as the DPF, EGR, or SCR components, the truck will not pass the test. Non-emissions fault codes may not trigger an automatic failure, but resolving engine warnings before your test date is always recommended.Clearing fault codes right before an inspection resets the computer’s internal readiness monitors. If monitors are incomplete, the test returns a “Not Ready” result, which cannot be accepted as a passing filing. The truck must then undergo normal driving to reset the monitors. Fix mechanical issues first to ensure a smooth testing process.
When a vehicle misses its Clean Truck Check deadline, the DMV places an automatic hold on its registration renewal. Standard renewal payments will not be processed until a verified passing test is uploaded to the state’s CTC-VIS system by a certified tester.After a passing test is filed, CARB updates the DMV and registration holds typically clear within a few business days. Choosing a mobile tester who submits results on the day of service ensures your block lifts as quickly as possible – and if you’re already stuck, our DMV registration hold removal service walks you through it.
A Notice to Submit to Testing (NST) means a roadside remote sensing unit identified your truck as a potential high emitter. Once issued, you have 30 calendar days to complete a passing OBD scan with a certified tester and submit the records to CARB.Roadside sensors monitor major traffic arteries regularly. Because the 30-day window includes transit and processing time, scheduling your test quickly is essential. We provide priority scheduling for operators handling active NST notices to help avoid state penalties.

A single mobile visit handles your entire fleet conveniently, at the same $150-per-truck rate.
Under current regulations, 2013 and newer diesel trucks must undergo OBD testing twice a year. Deadlines correspond to your DMV registration expiration date and its six-month midpoint. Passing test results must be filed within the 90-day window prior to each deadline.Beginning October 1, 2027, CARB will transition to a quarterly testing schedule, requiring four submissions annually. Setting up a regular testing routine with a reliable mobile provider now ensures your operation stays compliant as requirements evolve.
