One of the biggest doubts for expats living in Spain is what will happen regarding driving licences and if international driving permits will be needed.
Current driving licences issued by the UK authorities will entitle their holders to drive in Spain for a period of nine months from the date of the UK’s exit from the EU. If you are a resident in Spain and want to continue driving there, you will have to exchange your licence to a Spanish one. You can start this process via the DGT website.
You can still use your Spanish licence in the UK for short visits or exchange it for a UK licence without taking a test if you return to live in the UK.
