B9a - Entroncamento com via sem prioridade (Entroncamento com via sem 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: entroncamento com via sem prioridade: indicação de entroncamento com via em que os condutores que nela transitem devem ceder passagem; os símbolos indicam a configuração do entroncamento. 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 B9a sign, officially 'Entroncamento com via sem prioridade', means that you are approaching a junction where the traffic on the intersecting road has priority. You must yield to these vehicles and only proceed when it is safe to do so.
When you see the B9a sign, you must be prepared to yield. This means you should reduce your speed and check the intersecting road for traffic that has priority. Only proceed if there is a safe gap and your action will not force them to brake or swerve.
Not necessarily. The B9a sign requires you to 'yield' (ceder passagem), which means you must give way to traffic with priority. If the intersecting road is clear, you may proceed without stopping. However, if there is traffic with priority, you must stop or slow down sufficiently to allow them to pass first.
A common trap is assuming normal priority rules apply, especially if there are no visible markings. The B9a sign overrides these assumptions. Another trap is confusing it with signs that indicate you have priority. Always remember B9a means you must yield to traffic on the intersecting road.
The B9a sign is crucial because it explicitly alters the default priority rules. While generally traffic from the right has priority at uncontrolled junctions in Portugal, this sign clearly indicates that the priority lies with the traffic on the intersecting road, regardless of which side they are coming from.
