Tielinjat

Tielinjat are road markings painted on pavement to regulate traffic in Finland. They include center lines that separate opposing directions, lane markings that define individual lanes in the same direction, and edge lines that delineate the road boundary. Other markings indicate turning opportunities, bike lanes, pedestrian crossings, and reserved lanes such as bus or tram lanes. The color and style (solid, dashed, double lines) convey rules: dashed center lines generally permit overtaking when safe, solid lines usually prohibit crossing, and double solid lines are a strong restriction.

In urban areas, additional markings clarify lane usage at complex junctions, bus lanes, and dedicated cycle facilities. Markings are designed to be highly visible under various conditions and are reinforced with reflective materials. Winter maintenance in Finland affects visibility, so durable paint or thermoplastic with retroreflective beads is common.

Governing bodies: Road markings are specified by national authorities, notably the Finnish Transport Infrastructure Agency (Väylävirasto), and are created in accordance with national standards and European guidelines and the Vienna Convention on Road Signs and Signals.

Purpose: The primary function of tielinjat is to improve road safety and traffic flow by providing clear, machine-readable instructions to drivers, cyclists, and pedestrians. They work in conjunction with traffic signs and road design to indicate permitted movements and to define safe paths for all users.
