Steps in the Clean Truck Check Testing Process
Clean Truck Check testing is designed to confirm emissions systems are functioning correctly and that required results are submitted to CARB.
1) Initial vehicle check
A quick review of vehicle readiness (including common issues like recent “code clears,” which CARB notes can affect test submissions until minimum operation thresholds are met).
2) Emissions compliance testing
Periodic testing requirements and due dates are managed through CTC-VIS.
3) Documentation / submission review
We ensure submissions align with program requirements and that the vehicle owner can see results in CTC-VIS.
4) Compliance status and next steps
If follow-up is needed, we help you understand the timeline (especially important if CARB has issued an NST letter with a stated response window).
Why each step matters
Each step helps prevent “surprises” that can cause delays or missed compliance deadlines.
