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 addition to Finland, the card must be valid in the entire EEA.
- The details in the green card must correspond to the details of the vehicle.
- The card must be original and completely filled in.
- The card has a period of validity of at least 15 days.
- The card was issued by an insurance company entitled to issue it.
- One of the EEA countries has been crossed over on the green card.
- The details of the green card do not agree with those of the vehicle.
- The card details are incomplete.
- The card has expired.
- The presented green card has been issued by an insurance company that is not entitled to do so.
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.
- Winter tyres must be used from the beginning of November to the end of March, if required by weather conditions.
- Studded tyres may be used from the beginning of November to the end of March, and at other times only if required by weather conditions.
- The speed limits on highways are lower in wintertime (100 km/h ≥ 80 km/h and 120 km/h ≥ 100 km/h).
- The required minimum tread depth in tyres: 1.6 mm for normal tyres, 3.0 mm for M+S tyres.
- If the vehicle is not fitted with daytime running lights, headlamps must be used even in daytime.
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.
