SPANISH DRIVING LICENCE – Do I need to pass a new test in Spain? 
The United Kingdom effectively ceased to belong to the European Union as of December 31, 2020, so all traffic agreements within the EU are no longer valid for license holders:
As of January 1, 2021, the general regulations will apply and the permits issued by the British authorities will only enable you to drive in Spain for six months, from the entry of the holder in Spain or from the date of obtaining residence legal, not being valid to circulate in our country from that moment.
For holders of a British driving license who are resident in Spain as of December 31, 2020, the six-month period will begin to run from January 1, 2021. For holders of a British driving license who have requested the exchange, replacement or renewal before December 31, 2020, it is recalled that they will be processed provided they have been verified by the United Kingdom authorities before January 1, 2021. Applications submitted after December 30, 2020 will not be processed.
If you did not request the exchange before December 31, 2020 YOU WILL HAVE TO OBTAIN A NEW SPANISH DRIVING LICENSE.

Hello Mrs Williams, unfortunately, this is the latest news about it. We don’t know if anything will change, according to them, all the brits have had enough time to do all the paperwork in the transition Brexit period.
Hopefully, EU-UK will do something about it.
