Do I need a Green Card to travel to Europe?
Following further negotiations, the European Commission has agreed that the UK should be part of the Green Card Free Circulation Area.
From 2nd August 2021, you'll no longer need a Green Card as proof of valid motor insurance when travelling abroad.
If you are driving with a trailer or caravan, you may need to register it before travelling. Details can be found at: https://www.gov.uk/guidance/trailer-registration
