it's the sticker you put in the windshield of your car, has to be renewed every year, usually end summer til mid november, a 90 days window, within that time period all car holders have to pay the tax and put the new sticker on.
sidequestion to renewal:
i did this year completely forget about the stcker of the revista, saw the different one on a friend's new car a while ago and realized that i did not buy one for my own car this year. when i went to the Banco Reservas in PC to buy one they told me they actually have the sales of that sticker on hold due to modufucations done to the selling forms.
that been around 2 months ago.
since then i forgot about that thingy again, til this Marbete/Placa thread reminded me of the other sticker.
does anybody know if they finished their modifications on the form and the stickers are again available at Banco de Reservas now??
