Parking is straightforward in Finland. Finland uses parking discs for parking and signs tell you when they are needed. There are parking bays denoted by a sign with a big 'P' on it. Another sign will tell you of restrictions that apply. Elsewhere parking is allowed just about anywhere as long as you are not causing an obstruction. If your car is parked in an area where it is hard to see and could be hit then you must put your lights on. Cars must park facing in the direction of the traffic and at least five metres from any pedestrian crossings or intersections.
Look out for the parking bays annotated with a 'P' signs will tell you how long you can park there and what the cost will be. There are parking lots where you can you park in the open air or in winter, park in an enclosed garage.
Enforcement of parking is done by the police but generally only if you're causing an obstruction or overstaying your ticket. You'll get a fine payable at the local police station, bank or online.
Finland does follow the European Blue Badge scheme. Parking places which are reserved for disabled people are marked with a wheelchair symbol.
