Sinais de obrigação

Um sinal de obrigação indica aos condutores o que devem fazer. Em vez de proibir ações, impõe obrigações como seguir uma direção específica, utilizar uma determinada via ou manter uma velocidade mínima. O objetivo é orientar o trânsito de forma segura e eficiente, garantindo comportamento uniforme onde isso é necessário para a ordem e segurança.

Viragem obrigatória à esquerda ou direita.

Passar o obstáculo por qualquer um dos lados.

Obrigatório seguir em frente ou virar à direita.
