C2 - no traffic in either direction (Trânsito proibido) belongs to the Portuguese prohibitory signs category in the Regulamento de Sinalização do Trânsito. It normally uses the red-bordered regulatory style associated with restrictions, limits, bans, or cancellation of a previous restriction. The official wording is: trânsito proibido: indicação da proibição de transitar em ambos os sentidos. It creates a binding restriction from the point where it applies and normally continues until it is ended, replaced, or limited.
