Definition of A12

A12 - Vento lateral (Vento lateral) belongs to the Portuguese warning signs category in the Regulamento de Sinalização do Trânsito. Visually, this belongs to the triangular red-bordered warning family used in Portugal, with the internal symbol identifying the specific hazard. The official wording is: vento lateral: indicação da proximidade de um troço de via em que é frequente a acção de vento lateral bastante intenso; a orientação do símbolo representado no sinal indica o sentido predominante do vento. Its purpose is to warn early enough for the driver to adapt before the danger point. 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.
