To rent a car, you must be at least 20 years old (age may vary by car category) and have held your license for 1 year. Drivers under the age of 25 may incur a young driver surcharge.
Seatbelts are mandatory and children up to 3 years need to be seated in a child's seat (or belt if a child's seat is unavailable). Speed limits in Finland are as follows: City 31mph/50kph, open Roads 62mph/100kph and highways 74mph/120kph.
Traffic travels on the right and headlights need to be turned on at all times. Using a cell phone while driving is strictly prohibited, be sure to use a handsfree set.
Finland has a relatively low population (approximately 5 million) and driving along the quiet, tranquil country roads is a true delight. In most regions, small meandering roads are strategically built around the many lakes in order to get from one place to the other.
The further up north, the fewer roads remain. Helsinki is located due south. To the northeast of Helsinki, at about 300 km you will find the enchanting region of Punkaharju. The woods and lakes are lovely here and human settlements are rare. Rock drawings from the Bronze Age were found in this region.
Furthermore, Lapland is well worth a visit, although this province (and region) is quite a drive from Helsinki. The distance between Helsinki and Lapland's capital Rovaniemi is about 700 km. When you decide to make this trip, a pit stop and overnight stay in Kuopi are necessary, Kuopi is the largest city of eastern Finland.
Another option is booking your rental car through EasyTerra, a company that compares the rates of local car rental companies for your convenience.
