I got this from the NY DMV site.
THE LOW-ENHANCED EMISSIONS INSPECTION FOR THE UPSTATE AREA
A 1995 or older model year vehicle, or a vehicle that weighs 8,501 lbs. or more is required to have a low-enhanced emissions inspection if the vehicle:
* Is registered in the Upstate Area, and
* Is not exempt from emissions inspection.
The Upstate Area includes the 53 counties located north of the New York City Metropolitan Area (NYCMA). The NYCMA includes New York City, Nassau County, Suffolk County, Rockland County, and Westchester County. The Upstate Area includes all other counties in NYS.
To conduct a low-enhanced emissions inspection, the inspection station must be licensed by the NYSDMV to conduct NYVIP inspections.
