This PA11d panel is a supplementary Portuguese traffic sign used to indicate that a main sign's instruction, restriction, or prohibition only applies to specific types of vehicles. You must always read this panel in conjunction with the main sign it accompanies. It helps clarify which vehicles are affected, for example, by indicating if a rule applies only to light passenger cars, heavy goods vehicles, or even vehicles displaying a disabled badge.
Master the interpretation of the PA11d additional panel, which specifies how main traffic regulations apply only to certain vehicles. Essential for accurate theory test revision, this panel clarifies complex road rules for specific vehicle types in Portugal.
PA11d - 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. Visually, this is a supplementary plate placed with a main sign; its position matters because it completes or limits that main sign instead of standing alone. The official wording is: painéis indicadores de veículos a que se aplica a regulamentação: destinam-se a indicar que a obrigação, restrição ou proibição especial 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 e mistos, 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 portadores do dístico de deficiente, o modelo n.º 11e, para automóveis pesados de mercadorias, o modelo n.º 11f, para motociclos, o modelo n.º 11g, para ciclomotores, o modelo n.º 11h, para velocípedes, e o modelo n.º 11i, para veículos agrícolas. 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.

The PA11d panel is a supplementary sign in Portugal that works with a main traffic sign. It specifies that the rule on the main sign only applies to the particular vehicle type shown on the PA11d panel, such as 'vehicles displaying a disabled badge'.
You must always read the PA11d panel together with the main sign. The panel modifies the main sign's instruction, indicating precisely which vehicles must comply. For example, if a main sign prohibits entry, and a PA11d panel shows a disabled badge symbol, only vehicles with that badge are affected by the prohibition.
A PA11d panel on its own is incomplete and does not convey a traffic instruction. It must always be placed below a main traffic sign. Its purpose is to limit or clarify the scope of that main sign's message for specific vehicle types.
Yes, the PA11 series includes different models for various vehicle categories. For instance, PA11d specifically refers to vehicles carrying a disabled badge. Other models exist for passenger cars, goods vehicles, motorcycles, cyclists, and agricultural vehicles, each tailored to a specific vehicle type.
A common trap is forgetting to read the PA11d panel together with the main sign, leading to misinterpreting the restriction or prohibition as applying to all vehicles. Learners might also incorrectly assume the panel applies universally or to a vehicle type not specified.
