Who really has priority on a Polish roundabout? One sign changes everything
The blue C-12 sign alone does not settle every case. Learn what Give Way changes and how lane changes and trams affect priority.
On most Polish roundabouts, vehicles already travelling around the island have priority because the entrance displays C-12 “roundabout” together with A-7 “Give Way.” It is A-7 that orders entering traffic to yield.
What C-12 alone means
C-12 specifies the required circulation direction around an island or square. By itself it is not a priority-road sign. Without A-7 or another traffic control measure at the entrance, general priority rules determine the order.
This layout is less common—which makes it a useful examination trap.
The typical entrance: C-12 plus A-7
With both signs, give way to traffic on the circulating carriageway. Slow down and assess every lane your vehicle may enter. Another driver's indicator is not proof that the vehicle will actually leave.
Changing lanes
A driver changing lane must give way to traffic already using the destination lane. Wanting to leave the roundabout does not create a right to cross an adjacent lane.
On a multi-lane roundabout, analyse separately:
- priority when entering,
- priority when changing lane,
- road markings and direction arrows,
- traffic lights when operating.
What about trams?
No single slogan covers every case. A tram may be entering, circulating or leaving, and its priority also depends on lights and signs. Identify the traffic control first, then apply the rules for rail vehicles.
An indicator does not grant priority
Signalling intention does not authorise a manoeuvre ahead of other traffic. Before changing lane or leaving, confirm that the move is safe and follows the markings.
Five questions for every diagram
- Are traffic lights operating?
- Which signs face my entrance?
- Which lane am I in and where am I moving?
- Am I changing lane?
- Is a tram or directional marking involved?
Practise entrance, lane movement and exit separately in examination situations. A roundabout is not one rule but a sequence of decisions.
