1. One-way traffic

One-way traffic means that vehicles on a road or carriageway may travel only in one designated direction. The permitted direction is normally indicated by traffic signs, lane arrows or road markings.

Some road users, such as cyclists or public-transport vehicles, may be allowed to travel in the opposite direction when signs expressly permit it. A one-way road does not by itself determine the speed limit, priority or parking rules.

How should I read a one-way restriction in Finland?

A one-way street’s direction is determined by its traffic signs. Finland’s signs can distinguish the general carriageway arrangement from an authorised two-way cycling exception.

May cyclists travel against the general traffic direction in Finland?

Check the supplementary cycling permission and the allocation of any cycle lane or path. The Finnish Road Traffic Act provides signs for the cycling exception; cyclists must not infer it merely from the absence of an approaching car.

Does one-way traffic give me priority or a different speed limit in Finland?

A one-way restriction concerns direction. Continue to follow the applicable speed limit, signals, give-way or stop controls and junction-priority rules. Where authorised counterflow traffic exists, check for it before turning or crossing; your permitted direction is not automatic junction priority.
