Finland

Overall, the country is flat. Sweden and Norway have mountain ranges over 2,000m, but Finland's highest point is only about 1,400m.

If the crosswalk sign in the Nordics shows 5 stripes, it's Finland.

Street names often end in "-tie" or "-gatan."

Company names carry "Oy" (short for osakeyhtiö), meaning a joint-stock company.

On narrow Nordic roads, the "Passing place" sign uses an arrow only in Finland.

The centerline uses yellow and white dashes.

In the Nordics, log houses painted a deep red (Falu red) are distinctive.

If you know it's Finland but not where, dropping your pin just above Äänekoski gives consistently solid points. For a randomly chosen Finnish road, this averages over 4,300 points (4,385 exactly).

If signs show Finnish and Swedish together, or Swedish alone, that points to the southern or southwestern coast.

If signs pair the text with Northern Sami, that's the northernmost area.

If the surroundings are flat and the road surface looks reddish, it might be the Åland Islands.

If a lake appears every short stretch of road, with the opposite shore always in sight and intricate shorelines alternating with forest, that's the central-eastern Lakeland.

If the forest breaks and horizon-flat farmland opens up, dotted with barns and houses, that's Ostrobothnia (Pohjanmaa) on the west coast. It is exceptionally flat even by Finnish standards.

If the road suddenly ends at the sea in a ferry terminal, and narrow bridges carry you from one small rocky island to the next, that's the southwestern Archipelago Sea.

If the forest breaks and barley, oat, or wheat fields spread as far as you can see, with red barns scattered among them, that's the southwest (around Turku and elsewhere). Grain fields cluster in the southwest and the west-coast Pohjanmaa; in the east and north, pasture dominates.

Reindeer walking along the road, or a reindeer-warning sign by the roadside, mean the northern third of the country (Lapland region and the northern parts of North Ostrobothnia and Kainuu regions).
