Tama, vanity plates, i.e. 888888 & 777777, are the one which are supposedly exempted sa coding that is with regards to MMDA & LTO.
Special plates, i.e. 2/3-digit plates, GMA 100, LRM 99 are not exempted sa coding.
di ba vanity plates are to be placed on top of or above the rear plates? so you will still be flagged down by enforcers since they will see your front plates first. then what, you'll explain to them that you have vanity plates at the back?
