Long-term solutions depend on future discussions between the EU and the UK
See below for the measures preparing the EU for a no-deal Brexit:
UK airlines would be able to provide services to EU countries provided EU companies are also able to do so to the UK.
The validity of rail safety authorisations would be extended to ensure the continuity of rail services between the UK and the EU, provided the UK does the same.
IN SOME AREAS: NO SPECIAL MEASURES IN PLACE
In many areas, no special measures are in place to replace existing relation with the UK in case of a no-deal. This could lead to additional costs and extra paperwork and it would be a good idea to check with relevant authorities of your country or region.
Driving licences issued by one EU country are automatically recognised by other member states. When the UK leaves, this will no longer apply to British licences. EU nationals wishing to drive in the UK will need to check with UK authorities if their licence is valid, while Brits will need to check with the national authorities of each EU country in which they wish to drive. International driving licences are valid across the UK and EU.
The EU pet passport, which allows your pet to travel with you to another EU country, will no longer be valid in the UK. It is likely more paperwork will be needed when taking your pet to or from the UK.
