If you are one of those people who believed that their UK licences would be invalid after Brexit & decided to change now rather than wait, fear no more.
"As the United Kingdom approaches its exit from the European Union, many British people are concerned about the validity of their post-Brexit driving licence. But don’t worry, their licence will be valid as a European licence.
The British can be reassured: to overcome the question of the validity of their driving licence, an order dated 3 April 2019 and published in the Official Journal on 7 April 2019 provides a very simple solution. Holders of a driving licence issued by the United Kingdom authorities who have acquired their normal residence in France on the date of leaving the United Kingdom from the European Union (i.e. at least 185 days of residence) will continue to have their licence recognised under the same conditions as holders of a licence issued by an EU Member State. Their licence will therefore allow them to drive throughout the territory without any action being required.
A few special cases will still require an exchange procedure: in the event of an offence, expiry of the permit or obtaining a new category. If the user lives in Paris, he/she must send his/her file to the Resource Centre for the exchange of foreign driving licences and international driving licences to the Paris Police Prefecture (CREPIC) or to the Centre d’expertise et de ressources des titres (CERT) in Nantes if he/she lives outside Paris.
