The PA13a sign, known as 'Diagrama de via com prioridade' in Portugal, is an additional panel that visually illustrates how a priority route changes direction. It's crucial to understand that this panel is never used alone; it must always be interpreted alongside a main traffic sign, typically sign B3 (Stop sign) or other priority signs. The thick line on the diagram indicates the priority route, and the panel clarifies where and how that priority applies, helping you navigate junctions and changing road layouts safely and correctly.
Master the PA13a 'Diagram of Priority Route' supplementary panel, a crucial element in Portugal's traffic signage. This sign clarifies priority changes and is vital for correct navigation and passing your theory test revision.
PA13a - Diagrama de via com prioridade (Diagrama de via com prioridade) belongs to the Portuguese additional panels category in the Regulamento de Sinalização do Trânsito. Visually, this is a supplementary plate placed with a main sign; its position matters because it completes or limits that main sign instead of standing alone. The official wording is: diagrama de via com prioridade: destinam-se a indicar que a via com prioridade muda de direcção; deve utilizar-se conjuntamente com o sinal B3; o traço largo representa a via com prioridade. It must be read together with the main sign; alone it is incomplete, but together it can change distance, duration, direction, affected users, or exceptions. 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 PA13a sign is a Portuguese additional panel that shows a diagram of how a priority route changes direction. It works with a main sign to clarify the priority path, with the thick line on the diagram representing the priority route.
No, the PA13a sign is a supplementary panel and is always used in conjunction with a main traffic sign, such as the B3 (Stop) sign. It cannot convey a complete instruction by itself; its purpose is to modify or clarify the main sign it accompanies.
You must read the PA13a panel together with the main sign it is mounted below. The panel will visually guide you on the direction of the priority route. Follow the thick line on the diagram to understand where the priority lane is, especially at junctions or complex intersections.
A common mistake is trying to interpret the PA13a sign in isolation from the main sign. Learners might also fail to understand that the thick line specifically shows the direction of the priority route, leading to confusion about right-of-way at intersections. Always consider the combined message of the main sign and the additional panel.
The PA13a sign itself doesn't directly dictate speed or stopping. However, by clarifying the priority route, it indirectly influences your decisions at junctions. If it's paired with a Stop sign (B3), it helps you understand which path requires you to stop and yield, and where you should proceed with priority.
