Exit day is 31st October
This is a better site – I haven’t fully tested it (obviously) but it answered correctly (eventually after many fields) to the GB car sticker aspect
** If you display the Euro symbol and Great Britain (GB) national identifier on your number plate, then you will NOT (my capitals) need a separate GB sticker when travelling within the European Union.
The Euro symbol must:
be a minimum height of 98mm
have a width between 40 and 50mm
have a reflective blue background with 12 reflecting yellow stars at the top
show the member state (GB) in reflecting white or yellow **
