What an emissions inspection can cost here
This station is outside the New York Metropolitan Area, so under the DMV fee chart the OBDII emissions inspection costs at most $11.00. Stations may charge less, and the safety inspection is a separate fee. The DMV's own wording is quoted on our New York rules page. Call the station to confirm hours and prices; this page does not show either.
