Road signs in Portugal explained

Road signs in Portugal are governed by the Portuguese: Regulamento de Sinalização do Trânsito^[1] (Road Signage Regulation) of the Portuguese Republic.

They are installed along the road on the right side of the road and are subdivided into warning signs (group A), regulatory signs (groups B-D), subdivided into priority, prohibition, obligation and specific prescription signs, indication signs (groups H-T), subdivided into information signs, pre-signalling, direction, confirmation, location identification, supplementary signs, additional signs and temporary signs (groups AT and TC).

The typefaces used on road signs are derived from the British Transport and Motorway typefaces. Portugal is an original signatory to the Vienna Convention on Road Signs and Signals.^[2]

Influences

• Angola largely shares the same road signage designs used in Portugal alongside SADC-issued road signs which made them transitional in nature.^[3]
• Yemen largely shares the same road signage designs used in Portugal - except those languages used are bilingual (Arabic and English) - have different symbols (e.g. camels, mosques, sand dunes, date palms, crescents).
