A personal identity code and a registered address
Your existing licence, valid
A medical certificate and eyesight check for most applications
For the full course, enrolment at a Finnish driving school

Step-by-step

1
Check whether your licence is exchangeable
EU/EEA licences remain valid and can be exchanged. A defined list of other jurisdictions — including Switzerland, Japan and San Marino among others — can exchange, some after a driving test. If your country is not on the list, the answer is the full Finnish licence process. Traficom publishes the current list and it does change.

Apply through Traficom's service points
Applications are handled by Traficom's appointed service providers rather than at a police station. Bring your licence, identity document, identity code, a medical certificate where required and a photograph to Finnish specification.

3
Take the test early if one is required
Where a driving test is required for exchange, book it as soon as the application allows. Finnish tests include winter driving competence and the standards are exacting about observation and anticipation.

4
Fit winter tyres and know the dates
Finnish law requires winter tyres on cars when weather or road conditions require it during the winter months, and studded tyres may only be used within a defined seasonal window. Both rules are enforced. Hire cars in winter are normally compliant but check rather than assume.

5
Understand Helsinki parking before buying a car
Inner Helsinki operates resident parking permit zones tied to your registered address, with paid parking elsewhere and vigorous enforcement. A parking space in a building's garage is a separate and expensive thing, often rented rather than included.

Consider whether you need a car at all
HSL's zone AB card covers trams, metro, buses, local trains and the Suomenlinna ferry, and the network reaches the national park at Nuuksio via Espoo. Most inner-city residents do without a car entirely, and a car-sharing membership covers the occasional need at far lower cost.

Things most newcomers don’t know

Winter tyres are a legal requirement here, not a precaution, and the studded season has its own dates.

Finnish law requires winter tyres on passenger cars during the winter months whenever weather or road conditions call for them, with minimum tread depth specified. Studded tyres are additionally restricted to a defined seasonal window, which means running them outside it is an offence even if the weather looks wintry. Drivers arriving from countries where winter tyres are advisory rather than mandatory get caught by both rules in their first year, and insurers take a dim view of a claim on the wrong tyres.

The exchange list is specific and short, and Traficom revises it.

Beyond the EEA, only a defined set of jurisdictions can exchange a licence into a Finnish one, some after a practical test. The list is published by Traficom and it has changed over time — most notably after Brexit changed the status of UK licences. Checking the current list rather than a two-year-old forum post is worth doing before you make plans, because the alternative is the full Finnish licence course at Finnish driving school prices.

Speeding fines here are calculated from your income, which changes the arithmetic entirely.

Finland uses day fines for many traffic offences: the penalty is expressed in units and the value of a unit is derived from the offender's disposable income. That produces individual fines that have run into tens of thousands of euros for wealthy drivers and have made international news more than once. For an ordinary salary the amounts are ordinary, but the design means a speeding ticket is not a fixed cost you can shrug at.

A national park is reachable on the ordinary transport card, which removes the usual reason to own a car.

Nuuksio National Park sits inside the Helsinki commuter region and is reachable by local train to Espoo and then a bus, all within HSL's ordinary zone system. Combined with Finland's everyman's right to walk, forage and camp on uncultivated land, that means the outdoors is accessible without a vehicle. In most cities a car buys access to nature; here the transport card already does, and inner-city car ownership is correspondingly low.

Common mistakes to avoid

Assuming a non-EEA licence can be exchanged without checking Traficom's current list.
Running summer tyres into the statutory winter period.
Using studded tyres outside the permitted seasonal window.
Buying a car without securing a parking space or a resident permit.
Underestimating a Finnish speeding fine, which scales with your income.
