AA car insurance policyholders can drive in the EU, and in several other European countries, and get the same level of cover you have in the UK for up to 90 days during the 12 months of the policy.
If you drive abroad in Europe you'll need to take your AA Certificate of Motor Insurance and the log book (V5C) for the vehicle, as well as your driving licence.
From 2 August 2021 a Green Card (or International Motor Insurance Card) is no longer required for travel in the EU and the EEA states. You also don't need a Green Card for Andorra, Bosnia and Herzegovina, Serbia and Switzerland.
Instead of the Green Card, your AA Certificate of Motor Insurance now proves you have the minimum insurance cover needed by law in the country you're visiting.
