The B9b road sign, officially 'Entroncamento com via sem prioridade', is a crucial priority sign used in Portugal. It alerts you to an upcoming junction where traffic on the connecting road has priority. You must be prepared to yield to these vehicles, ensuring they can proceed without obstruction. Understanding this sign is vital for safe navigation and success in your Portuguese driving theory exam.
Master the B9b road sign meaning for your Portuguese driving theory test. This essential traffic sign explanation helps you navigate uncontrolled junctions safely, ensuring you know when to yield to traffic approaching from the right.
B9b - 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.

This Portuguese road sign means you are approaching a junction where the traffic on the connecting road has priority. Your instruction is to yield to those vehicles. The specific configuration of the junction may be shown by symbols on the sign itself.
When you see the B9b sign, you must slow down and prepare to yield. Look carefully at the traffic on the intersecting road and only proceed when it is safe to do so, without forcing priority vehicles to brake or swerve.
Not necessarily. The B9b sign indicates you must yield, which means you should give way. If the intersecting road is clear, you may proceed without stopping. However, if there is traffic with priority, you must stop or slow sufficiently to let them pass.
A common trap is assuming you have priority if the other road seems less busy, or if there are no other signs. The B9b sign explicitly overrides normal assumptions by granting priority to the other road. Always interpret the signed priority rule correctly to avoid errors in theory exam questions about junctions.
The B9b specifically indicates an upcoming junction where the intersecting road has priority. Other signs might grant you priority (like a diamond shape) or require a full stop (STOP sign). It's essential to recognise each sign's unique instruction regarding yielding or proceeding.
