Traffic rules
Portugal
1. Priority over oncoming traffic
Priority over oncoming traffic means that drivers travelling in one direction have priority through a narrow section of road over drivers approaching from the opposite direction. The rule is normally indicated by a priority sign facing one direction and a corresponding give-way sign facing the other.
Drivers with priority must still approach cautiously and must not force their way through when the passage is blocked or already occupied. The signs regulate priority through the narrow section, not speed, parking or priority at nearby intersections.
How is priority over oncoming traffic controlled in Portugal?
Portugal’s prioridade nos estreitamentos da faixa de rodagem gives priority over opposing vehicles at the narrowing. The corresponding give-way sign reverses that duty; neither is a priority-road designation.

Can you enter an occupied narrow passage when you have priority in Portugal?
Do not force a conflict. Check the full available width and let a vehicle already committed to the passage clear it when both vehicles cannot pass safely. A priority control does not permit creating danger or disregarding a red signal or authorised instruction.

Does priority through a narrow passage extend to nearby junctions in Portugal?
No. A control releasing your direction or giving priority over opposing traffic concerns that passage. Junction priority, speed limits, crossings and any later restriction must be assessed separately from their own signs and rules.
