Driving in Finland

Briefing

Finland's road system is defined by two structural realities most visitors miss until they're on it: dipped headlights have been compulsory at all times — day and night, every road — since 1997 (the rural-roads-in-winter mandate dates from 1972, making Finland one of the earliest movers on DRL), and the country runs a seasonal speed-limit swap. The 120 km/h motorway limit drops to 100 km/h roughly between late October/early November and March, and the standard 100 km/h on main expressways drops to 80 km/h.

Exact dates are set each autumn by ELY-keskus regional authorities, signed locally — there is no nationwide flip date.

The 2020 Tieliikennelaki (729/2018, in force 1 June 2020) is the regime still being bedded in. Two things changed for foreign drivers: winter tyres are now mandatory between 1 November and 31 March when conditions warrant, not on calendar dates alone (the old Dec 1 – end of February rule is gone, and the police assess whether tyres were appropriate after the fact); and handheld phone use was redefined so you may now hold the phone when the vehicle is genuinely stationary, but not at red lights with the engine running on a moving traffic queue.

Studded tyres (nastarenkaat) are permitted from 1 November to the week after Easter.

The famous Finnish quirk is real and worth respecting: the päiväsakko (day-fine) system bills serious speeders as a multiple of monthly disposable income. The benchmark case is Nokia board member Anssi Vanjoki, fined €116,000 in 2002 for 75 km/h in a 50 zone on his motorbike in Helsinki — the fine equalled 14 days of his 1999 income.

The fixed liikennevirhemaksu (traffic penalty fee, €140–200) covers minor over-limit driving up to about +20 km/h; anything beyond switches to day-fines and a likely licence suspension.

There are no general motorway tolls or vignette — Finland is one of the few EU countries where intercity motorway driving is entirely free. The practical hazards sit elsewhere.

Around 1,500 moose and 13,000+ total ungulate collisions are recorded each year nationally (Statistics Finland), peaking in September–October; in the poronhoitoalue (reindeer-herding area covering roughly the northern third of the country, ~36%), 4,000–5,000 reindeer are killed or injured by traffic annually, mostly Oct–Dec on the E75 and Kemijärvi roads. You are obliged to call 112 even after a glancing hit — the Finnish Motor Insurers' Centre compensates the herd, but only if you report.
