Pay close attention to this sign and adjust your speed and observation accordingly to ensure safe passage and comply with Portuguese traffic law.
The B4 sign signals the end of a priority road, requiring you to yield to traffic on intersecting roads. Mastering road sign meaning is crucial for your theory test revision and safe driving practice in Portugal.
B4 - Fim de via com prioridade (Fim de via com prioridade) belongs to the Portuguese priority and yield signs category in the Regulamento de Sinalização do Trânsito. Visually, priority signs use highly distinctive shapes and symbols, such as the inverted yield triangle, the STOP octagon, the priority diamond, roundabout approaches, and narrow-road priority panels, so the driver can identify the rule before the conflict point. The official wording is: fim de via com prioridade: indicação de que a partir do local em que o sinal está colocado a via deixa de ter prioridade. It directly controls priority, so ordinary assumptions must give way to the signed rule. For theory preparation, connect the sign to a concrete driving decision: where to look, when to slow, whether to stop or yield, which route or lane to choose, and whether any panel changes the scope of the rule. On the road, interpret it together with markings, traffic lights, police directions, temporary works signs, and any additional panel placed with it. A strong exam answer explains both recognition and behaviour: not only what the sign is called, but what a safe and lawful driver must do next.

The B4 sign ('Fim de via com prioridade') means that the road you are currently on is ceasing to be the priority road. You must therefore be prepared to yield to traffic on other intersecting or merging roads that now have priority over you.
When you see the B4 sign, you should reduce your speed, increase your observation of other traffic, and be ready to yield or stop if necessary. Your usual priority on this road has ended, so you must not force other vehicles with priority to brake or swerve.
While the B4 sign requires you to yield, it specifically indicates the end of priority, rather than a general requirement to yield at every intersection. It's crucial to understand that your priority status is changing. Always interpret it in conjunction with road markings and other traffic signals.
A common trap is assuming you still have priority or not anticipating the need to yield. In the theory test, questions might assess your understanding of priority changes at junctions or when lanes merge. Remember that 'Fim de via com prioridade' means you must give way to those who now have priority.
If an additional panel is placed with the B4 sign, it modifies the scope of the rule. For example, a panel might specify a distance, a time, or a specific type of road user affected. Always read the sign and any accompanying panel together to understand the complete instruction.
