B9c - 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.
