Clean Truck Check (HD I/M) FAQ

Q: How often do I need to test my vehicle? A: As of the 2024 rollout, most vehicles require compliance testing twice per year. Ensure you check your specific deadlines in your CTC-VIS account, or ask us to help you look it up.

Q: Do you offer the "PSIP" test? A: The Periodic Smoke Inspection Program (PSIP) has largely been sunsetted and replaced by the Clean Truck Check (HD I/M). Our testing satisfies the new, stricter requirements that replaced PSIP.

Q: I have a "Check Engine" light on. Can you still test me? A: We can run the test, but you will likely fail. The new HD I/M program requires that there are no active emissions-related fault codes. We recommend repairing the fault and ensuring the light is off before scheduling your test.
