Green Cards (or International Motor Insurance Certificates, IMICs) are an international certificate of insurance issued by insurance providers in the UK. They’re used to verify that the motorist has the necessary third-party motor insurance cover for driving in the country being travelled to.
Green Cards are guaranteed through agreements between the countries that issue them. With this agreement the driver’s insurer will honour any claims made against the policyholder for incidents taking place while they’re driving within the EU, EEA, Andorra, Bosnia & Herzegovina, Serbia and Switzerland.
