The LTSA will replace regular issue vehical plates if the prefix had word GUN cos some peeple get triggered (sniggers!) by the word. This same LTSA refused change a plate where person was ackshully being hassled cos it had FAG and guy was blue collar as and getting picked on. Middle class feelings over blue collar being bullied. Nice to know the pecking order aye mate.
Also, can still get custom plates with GUN on it. Like why tho? Good way to get the boys taking a gander to see if you need taxing. Never let a vehical like that park up outside you're pad aye or the boys might send a prospect sniffing for your gun safe. Gotta collect 'em all right.
