You need to apply for the green card (International Insurance Card) from Verna before setting off. In the case of a vehicle with a secured loan/financing agreement from a financing company, a written confirmation that the vehicle is permitted to be taken out of the country must be obtained from the relevant company. The confirmation must be presented when applying for a green card.
