TOG= Traffic operations Group (Ithink)
but more clear would be TMU- Traffit Management unit, usually drives XR8 Or SS marked highway patrol cars
when you get busted , they will give you a fine for driving a high powered vehicle. $156 or something like that and sometimes if the coppa is a real c*nt he will give you a cout summons, and if your car is modded, you will most likely will cop a nice yellow window sticker(defect)....
good luck in your quest for a skyline dude
