After Brexit, the UK is no longer covered by the EU rules for mutual recognition of driving licences.
The Danish Road Traffic Authority does not have the basis for evaluating the UK rules for use of driving licences from Denmark and other EU countries when driving in the UK after Brexit. It is therefore recommended that you follow the development with the British authorities.
If your stay in Denmark is temporary, it is possible for you to use your British driving licence since the Danish rules state that driving licences done in Latin-script, or provided with a translation into Danish, English or French, can be used in Denmark.
This might not be the case in other EU countries. Therefore, if you’re driving in another EU country than Denmark, it might be necessary for you to acquire an international driving licence to be carried alongside your regular driving licence.
If you have a driving licence issued in the UK and reside in Denmark, it will be necessary to exchange your driving license. The procedure depends on when your British driving licence was issued. If it was issued before the 1st of January 2021, you will be able to exchange your British driving licence without a driving test. If it was issued after the 1st of January 2021, it must be exchanged after the rules for third countries for which a driving test is mandatory. You can use your British driving licence for up to 180 days after the 1st of January 2021 or until 180 days have passed since taking residence in Denmark.
