New York inspection stickers labelled "2011" are yellow (they were issued in 2010). Stickers labelled "2012" are red (issued in 2011).
It is Blue.
A NYS Inspection sticker expires on the last day of the month it was punched during the year indicated on the sticker. If the sticker says "2011" and the month "June" is punched, the vehicle needs to be re-inspected on or before June 30, 2011.
I just did mines today in ny queens and it cost me $40.
As far as I know inspection stickers are good till the very last day, but I recommend you go in the begining or middle of the month to avoid lines from everyone else that's waited till last minute.
