A vehicle brought to Finland for temporary use must have valid motor liability insurance.
For the "licence plate agreement countries", i.e. the EEA countries, Andorra, Serbia and Switzerland, the vehicle's licence plate is basically sufficient proof of holding valid motor liability insurance. The insurance cover of vehicles coming from other green card countries is evidenced by a valid green card. Frontier motor liability insurance must always be taken out for a vehicle from a country outside the green card system before it arrives in the country.
In the above cases, frontier motor liability insurance must be obtained for the vehicle either from Customs or from the Finnish Motor Insurers' Centre. The minimum period of validity of frontier motor liability insurance policies is 30 days.
If the vehicle does not have a valid green card or frontier motor liability insurance, the authorities may prevent the vehicle from being used and levy sanctions due to non-insurance to the owner/keeper of the vehicle.
If a vehicle without licence plates is imported to Finland, a transfer permit and the associated temporary motor liability insurance must be obtained for it. They can be obtained from Customs of vehicle inspection stations. A foreign green card will not be accepted as insurance.
