PSIP: Why Comply?

The Periodic Smoke Inspection Program is for all heavy duty diesel powered vehicles that are over 14000 GVWR with an engine year at least 4 years old, as well as all 1998 and older trucks, of at least 6000 GVWR.

The California Air Resource Board requires that each qualifying, on-road diesel engine in your fleet participate in the PSIP (Periodic Smoke Inspection Program) by conducting annual smoke opacity test and repair those with excessive smoke emissions to ensure compliance and maintain at least two years of smoke test records.

The ARB randomly audits fleets, maintenance, and inspection records. The state of California is serious about clean air and their enforcement division has grown considerably over the last year. Stiff fines for non-compliance are issued monthly.
