In Finland, the rightmost lane is for normal travel. Left lanes are reserved mainly for overtaking.
When two lanes merge with no signs
The zipper merge (vuorotellen) technique should be used to take turns merging into one lane.
If using the left lane on a dual carriageway
The left lane is intended for overtaking or when preparing to turn left.
If lanes are divided by a solid white line
Solid white lines indicate a strict separation of lanes no changing permitted.
If lanes are separated by a broken white line
A broken white line means drivers may change lanes when safe to do so.

Diagonal arrows are used to guide drivers to merge or change lanes safely.
If driving slowly in a tunnel

Staying in the right lane improves predictability in low visibility.

Drivers must safely merge into the next lane and yield to ongoing traffic.
If you are alone in the left motorway lane
Always return to the right lane after overtaking on Finnish highways.
If changing lanes in Finland

When road narrows and merging is needed
When marked, drivers must alternate turns to merge smoothly.

Temporary markings are legally binding and override normal road lines.
If overtaking a cyclist
You must leave at least 1.5 meters lateral space when overtaking cyclists.

If turning right at a roundabout
Use the outer (right) lane to take the first exit on a roundabout.
If turning left on a multi-lane road
Left turns must be made from the leftmost lane to ensure safety and flow.
If a vehicle is overtaking you on two-lane road
Keep your lane steady and do not obstruct the overtaking vehicle.

You may cross the broken line to overtake if it is safe.
