Before travelling to Europe in your own vehicle we would advise you to check with your motor insurance provider to ensure the validity of your policy for driving in EU countries.
The requirement for green cards, which is an international certificate of motor insurance, when a UK registered vehicle is travelling in the European Economic Area has been removed by the European Commission from 2 August 2021. Therefore you are no longer required to carry a green card when you drive in the EU (including Ireland).
However, to ensure this is communicated widely the UK insurance industry will continue to issue green cards until 2 September 2021, when a vehicle is going abroad. You can get Green Cards from the insurance company insuring the vehicle or trailer.
We recommend contacting your motor insurance provider at least one month in advance of travel to check you have all the documentation you need.
