Painéis adicionaisSinais de trânsito
Um sinal de trânsito é um símbolo visual normalizado colocado junto das estradas para orientar e avisar condutores, ciclistas e peões ou regular a sua circulação. Fornece informações essenciais sobre condições da estrada, regras, direções e potenciais perigos, contribuindo para a segurança e a fluidez do trânsito. Os sinais apresentam várias formas e cores, como sinais triangulares de perigo, sinais circulares de proibição ou obrigação e sinais retangulares de informação, concebidos para permitir um reconhecimento rápido e uma compreensão clara.
Como são agrupados os sinais de trânsito na Irlanda?
O guia RSA distingue regulamentação, perigo e informação. Use os significados irlandeses, não as cores britânicas.

Um limite temporário de velocidade em obras é obrigatório na Irlanda?
Quando vigora um limite regulamentar temporário autorizado, deve respeitá-lo. Um aviso de obras não deve ser confundido com um novo limite numérico, mas as condições podem exigir uma velocidade inferior.
