I just read in the Guardian that GB stickers should be visible on cars when visiting the EU.
Renew your passport earlier than planned, buy a GB sticker for your car, and prepare to wait four months before you can take your ferret on holiday: these are all among the snippets of advice offered by the government’s new Brexit website for British citizens planning to travel to the EU after 31 October.
I am wondering if I therefore need to apply a 'D' sticker when I visit the United Kingdom?
I assume that there will a grace period but couldn't find any comment on this when doing a quick Google...
