You must always interpret this panel together with the primary sign it accompanies to understand the exact scope of the regulation.
This PA11o additional panel, specific to Portuguese traffic law, clarifies which vehicles the main road sign's regulation applies to, crucial for your theory test revision. Correctly interpreting this sign's meaning and its interaction with primary signage ensures lawful driving and aids in your overall driving knowledge acquisition.
PA11o - Painéis indicadores de veículos a que se aplica a regulamentação (Painéis indicadores de veículos a que se aplica a regulamentação) belongs to the Portuguese additional panels category in the Regulamento de Sinalização do Trânsito.

The official wording is: Painéis indicadores de veículos a que se aplica a regulamentação: destinam-se a informar que a mensagem constante do sinal apenas se aplica aos veículos que figurarem no painel; o modelo n.º 11a deve utilizar-se para automóveis ligeiros de passageiros; o modelo n.º 11b para automóveis de mercadorias; o modelo n.º 11c para automóveis pesados de passageiros; o modelo n.º 11d para veículos que exibam cartão de estacionamento para pessoas com deficiência; o modelo n.º 11e para automóveis pesados; o modelo n.º 11f para motociclos; o modelo n.º 11g para ciclomotores; o modelo n.º 11h para velocípedes; o modelo n.º 11i para veículos agrícolas; o modelo n.º 11j para veículos afetos ao serviço de determinadas entidades; o modelo n.º 11l para veículos elétricos; o. It must be read together with the main sign; alone it is incomplete, but together it can change distance, duration, direction, affected users, or exceptions. 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.
