Interpreting the C1 'Sentido Proibido' Sign

Master the meaning of the C1 'Sentido Proibido' (No Entry) sign to ensure safe driving decisions and pass your Portuguese theory test. This essential road sign explanation details how to interpret this prohibitory traffic sign correctly, crucial for your exam preparation.

Definition of C1

C1 - no entry (Sentido proibido) belongs to the Portuguese prohibitory signs category in the Regulamento de Sinalização do Trânsito. It normally uses the red-bordered regulatory style associated with restrictions, limits, bans, or cancellation of a previous restriction. The official wording is: sentido proibido: indicação da proibição de transitar no sentido para o qual o sinal está orientado. It creates a binding restriction from the point where it applies and normally continues until it is ended, replaced, or limited. 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.
