Two-Speed Idle Cutpoints
Note: The tailpipe test standards shown in the table below are no longer applicable to vehicles that require an OIS inspection. Effective March 9, 2015, an OBD Inspection System (OIS) is required when inspecting 2000 and newer model-year gasoline powered vehicles (unless over 14000 lbs. GVWR or those without OBDII), 1998 and newer diesel powered vehicles, and all hybrid vehicles

Legend:
ESC = Emissions Standards Category
GVWR = Manufacturer's Gross Vehicle Weight Rating
PASS/FAIL STANDARDS = Emission standards used to determine if a vehicle passes the emissions portion of the inspection -- a vehicle passes if the emission levels are equal to or less than the hydrocarbon or carbon monoxide standard for the idle or 2500 RPM inspection.
GROSS POLLUTER STANDARDS = Emissions standards used to designate a vehicle as a gross polluter. A vehicle is designated as a gross polluter if the emissions levels at the time of the initial inspection, before repairs, are greater than the gross polluter standards for hydrocarbon or carbon monoxide for the idle or 2500 RPM inspection.
HC = Hydrocarbon
CO = Carbon Monoxide
MIN. CO + CO2 = Minimum CO + CO2 dilution threshold
MAX. IDLE RPM = Maximum Idle RPM Limits
