if this is a serious post... you take the inspection sticker you put clear tape on it ... now the sticker and the tape are stuck together.. and you then use more clear tape and tape it to the windshield... u can techically take it down if u want.. if u get questioned u say u got a new windshield and the sticker lost its stickyness...
i learned this when i used to have tinted windshields..
and prety sure making a fraudulent inspection sticker (aka changing colors) is some sort of federal crime and u can probably get a few years in jail for it..
and yes the colors change per month... for a reason...
experince with this is i know people who do state nj inspections..
