The PA7b panel is a Portuguese supplementary traffic sign used to specify when the main sign it accompanies is active. It typically indicates days of the week, days of the month, or specific hours during which a prohibition or instruction applies. You must always read this panel in conjunction with the main sign to understand the complete instruction and modify your driving behaviour accordingly.
The PA7b panel is crucial for understanding when a primary road sign's instruction is active, helping you make correct driving decisions. Master this sign interpretation for your theory test revision and ensure compliance with Portuguese traffic rules.
PA7b - Painéis indicadores de periodicidade (Painéis indicadores de periodicidade) 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 periodicidade: destinam-se a limitar a determinados períodos de tempo a vigência da prescrição; o modelo n.º 7a indica os dias do mês em que a proibição constante do sinal se aplica, o modelo n.º 7b, os dias da semana, o modelo n.º 7c, as horas do dia, e o modelo n.º 7d, os dias da semana e as horas do dia. 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.

Get clear, practical answers to the most common questions about the PA7b - PA7b - Painéis indicadores de periodicidade (Painéis indicadores de periodicidade) road sign. Learn how the sign works, what rules it represents, and how it affects real driving situations.

The PA7b panel, known as 'Painéis indicadores de periodicidade', means that the main traffic sign it's attached to is only valid during certain periods. It specifies days of the week, times of day, or a combination, limiting the sign's effect to those specific times.
You must read the PA7b panel together with the main sign. For example, if a 'No Entry' sign is accompanied by a PA7b panel showing specific days, you are only prohibited from entering during those specified times. Outside of those times, the 'No Entry' rule does not apply unless indicated by another sign.
A common mistake is to ignore the PA7b panel or forget to check the time/day it specifies. Learners might also misinterpret the main sign as always being active, when in reality, the panel significantly alters its scope. Always consider the combined message.
While PA7b specifically refers to time-based restrictions (days/hours), other supplementary panels (like PA7a for days of the month, or others not listed here) can modify distance, extent, or direction. The core principle remains: always read the main sign and any supplementary panel as a single, complete instruction.
You might see a PA7b panel with signs related to parking restrictions, access limitations, or specific operational rules for certain roads or areas. For instance, a loading zone sign might have a PA7b panel indicating it's only active during business hours on weekdays.
