The Green Card is issued by the insurance company that has granted the motor liability insurance. The Green Card must be presented in the event of a road accident and, when required, to the border authorities. From the beginning of 2025, it can also be presented digitally, for example on a phone screen. In Lithuania, Luxembourg and Portugal, the green card must still be presented in paper form.

When entering countries outside the Green Card system, you have to acquire valid motor liability insurance at the border.
