3.2 Priority Signs, Stop Signs & Roundabouts

3.2 Priority Signs, Stop Signs & Roundabouts

While equal intersections rely on default rules, high-density traffic arterial corridors and multi-lane junctions in Finland are controlled by explicit priority signs (etuajo-oikeusmerkit). These signs override the default right-hand rule and create clear legal hierarchies at intersections and roundabouts (kiertoliittymä). Drivers must understand how to interpret standard yield signs, mandatory stop requirements, bending priority routes (taitettu etuajo-oikeus), and multi-lane circular flow regulations.

Priority Control Signs: Give-Way (B5) & Stop (B6)

Priority signs clearly establish which stream of traffic has precedence at an intersection.

Give-Way Sign (B5 - Väistämisvelvollisuus risteyksessä)

• Visual Identification: An inverted equilateral triangle with a red border and yellow background.
• Legal Duty: Drivers facing sign B5 must yield to all vehicles traveling on the intersecting road (approaching from both the left and the right).
• Speed Adjustment: Drivers must slow down early and stop if necessary to ensure intersecting vehicles can pass smoothly without taking evasive action or altering their speed.

Stop Sign (B6 - Pakollinen pysäyttäminen)

• Visual Identification: An octagonal red sign bearing the text "STOP" in white capital letters.
• Legal Duty: Sign B6 combines a mandatory complete vehicle standstill with full yielding duties toward all intersecting traffic.
• Stopping Location:
  1. Painted Stop Line (pysäytysviiva): The driver MUST bring the vehicle to a full standstill directly behind or at the painted stop line.
  2. No Stop Line Present: The driver MUST come to a full stop immediately before entering the intersecting carriageway at a point where visibility up and down the cross street is unobstructed.

Critical Risk Note: A rolling stop ("roller-stop") at a B6 sign is illegal in Finland. The vehicle's wheels must come to a complete, 100% standstill before proceeding.

Priority Road (B1) & Bending Priority Roads (H12)

The Priority Road sign (B1) is a yellow diamond with a white border. When posted along a road, it indicates that drivers on this road have right-of-way over all intersecting side streets until an End of Priority Road sign (B2) appears.

    ┌──────────┐
    │   B1     │  Yellow Diamond (Priority Road)
    └────┬─────┘
         │
    ┌────┴─────┐
    │   H12    │  Additional Panel (Bending Priority Road)
    └──────────┘  Thick curved line indicates main priority path

Bending Priority Road Panel (H12 - Taitettu etuajo-oikeus)

In complex urban junctions or rural highway bends, the priority road may curve through an intersection rather than proceeding straight. This is indicated by additional panel H12 mounted underneath sign B1 or yield sign B5.

• Reading Panel H12: The panel depicts the intersection layout with a thick line showing the priority route and thin lines showing secondary roads.
• Following the Priority Route: Vehicles following the thick line retain priority over all traffic entering from or exiting onto thin lines.
• Leaving the Priority Route: If a driver traveling along the thick line decides to leave the priority path (e.g., continuing straight onto a thin secondary road), they retain priority over vehicles on thin roads, but must yield to oncoming traffic continuing along the thick line.
• Direction Indicator Mandate: Drivers MUST use their direction indicators (blinkers) whenever following the bending priority curve or leaving it, clearly communicating their path to other road users.

Roundabouts (Kiertoliittymä)

A roundabout is a circular junction designed to maintain continuous traffic flow while reducing high-speed broadside collisions. Under Finnish law, roundabouts are regulated by a combination of the Roundabout sign (D2, blue circle with white revolving arrows) and the Give-Way sign (B5) posted on every entry arm.

Priority Rules Inside the Roundabout

• Entering Traffic Must Yield: All vehicles entering a roundabout face sign B5 and must yield right-of-way to all vehicles already circulating inside the roundabout.
• Clockwise Flow Prohibited: Traffic inside the roundabout moves strictly in a counter-clockwise direction around the central island.

Direction Indicator (Blinker) Rules in Roundabouts

Incorrect indicator usage in roundabouts is a frequent source of driving test failures in Finland. The rules are strict and unambiguous:

1. Entering the Roundabout: DO NOT activate directional indicators when entering a roundabout. Signaling left or right upon entry confuses other drivers who may mistake it for an immediate turn or lane change.
2. Circulating Inside: Maintain your vehicle's position inside the circle without signaling, unless executing an active lane change on a multi-lane roundabout.
3. Exiting the Roundabout: You MUST activate your right turn indicator (oikea suuntamerkki) immediately before taking your desired exit branch. Activate the indicator as you pass the exit immediately prior to your intended exit.

Multi-Lane Roundabouts (Monikaistainen kiertoliittymä)

Navigating multi-lane roundabouts requires advance lane selection and strict adherence to lane discipline.

Entry and Lane Selection

• Right Lane Entry: Used for turning right at the first exit or continuing straight ahead (unless overhead lane signs indicate otherwise).
• Left Lane Entry: Used for continuing straight ahead, turning left (3rd exit), or executing a U-turn (returning 180 degrees).

Lane Changes Inside

• Vehicles changing lanes inside a multi-lane roundabout must yield to traffic already traveling in the destination lane.
• When exiting from an inner lane, drivers must ensure they do not cut off vehicles circulating in the outer right lane.

Yielding to Pedestrians at Exits

Drivers exiting a roundabout are turning off a roadway and must yield to pedestrians and cyclists crossing the exit lane.
