FAQ's

Frequently Asked Questions

The Clean Truck Check is a California program by CARB that requires heavy-duty vehicles to undergo regular emissions checks to ensure they meet state air quality standards. It helps reduce pollution from diesel trucks and protect public health.

Any diesel or alternative-fuel vehicle with a GVWR over 14,000 pounds operating in California must comply — including out-of-state trucks.

Instead of taking your truck to a testing center, our certified mobile service comes to your location to perform the required emissions test. It’s faster, more convenient, and perfect for busy drivers or fleet operators.

OBD readiness refers to whether your truck’s On-Board Diagnostics system has completed its self-checks. If it’s not “ready,” your vehicle cannot pass the emissions test. We’ll help you determine readiness and guide you if action is needed.

Most checks take about 15–30 minutes per vehicle, depending on OBD status and any issues detected.

If your vehicle fails due to OBD issues or emissions-related faults, we’ll explain the problem and help you understand the next steps — including how to fix the issue and when to retest.
