Definition of D1e

D1e - Sentido obrigatório (Sentido obrigatório) belongs to the Portuguese mandatory signs category in the Regulamento de Sinalização do Trânsito. It normally uses the blue mandatory style, meaning the driver must perform the indicated positive action rather than merely avoid something. The official wording is: sentido obrigatório: indicação da obrigação de seguir no sentido indicado pela seta inscrita no sinal. It creates a positive duty to follow the indicated route, direction, lane, track, equipment requirement, or road-user 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.
