Annual PSIP inspections are required for all California-based fleets with diesel vehicles over 14,000 GVRW and engines over four years old. 

​

Inspection Requirements:

​

• All smoke opacity testing must conform to the SAE J1667 snap-acceleration test procedure

• All vehicles that do not pass the test must be repaired and retested, and all testing must be performed using an SAE J1667-compliant meter

• Opacity levels must meet new stricter limits of 5% or less (with some exceptions)
  We offer on-site and in-house opacity testing around your schedule with our state certified technicians.
