Drivers will need to carry their UK driving licence with them but may also need an international driving permit (IDP) to drive in some European Union (EU) and European Economic Area (EEA) countries. Please check the UK Government’s current advice on driving in the EU from 1 January 2021.
As for bringing a vehicle into the UK, there’s a set of actions that need to be completed, including notification, checks, registration, tax and insurance. If this isn’t done, either by the driver, fleet operator, trader or a contracted importer, relevant parties can be prosecuted.
