Do you need a Green Card??

A green card is an extension to your existing vehicle insurance and allows you to drive overseas with the same cover that you have at home. Vehicle insurers are legally obliged to extend third party cover to all countries within the EU, including any towed unit. This is legally only the minimum required for the country visited and may mean that your car is not covered for damage to it. Unless your insurance certificate states that comprehensive cover is extended to all EU countries, you should contact your insurer to extend your cover to the countries you intend to visit and for the total length of time abroad.
