The British embassy in Brussels is advising British nationals, living in Belgium to apply for a Belgian driving license, in case they currently hold a British. In the event of a no-deal Brexit on 29 March, these residents would otherwise have to pass a driving test, according to the embassy.
Citizens of one EU member state moving to another, can retain their national driving license until it expires. They can only be forced to exchange it in the event of a loss, theft or damage to the document, or if they live more than two years in the country, or after a traffic violation.
The possibility of exchanging a national driving license free of charge, for a document originating from the country of residence exists in all these cases. It is this possibility that the British embassy now recommends.
