Driving Permit for Sao Tome & Principe

Sao Tome & Principe is a destination where the practical answer about paperwork is clearer than the legal one. The islands do not appear among the contracting parties listed in UN treaty records for either the 1949 Geneva Convention on Road Traffic or the 1968 Vienna Convention, so an International Driving Permit carries no automatic treaty force here. The 1949 convention did apply historically, while the islands were Portuguese territory, but the independent country is not listed as a party today. In practice this changes little for visitors: the UK Foreign, Commonwealth & Development Office tells drivers to keep both an IDP and their UK driving licence in the car. The permit's most useful role here is translation, since Portuguese is the official language and an IDP renders your licence details into a form a police officer or rental agent can read at a glance.

An IDP is never valid on its own, so your original national licence must travel with it at all times. No official maximum period for driving on a foreign licence here is published in a form we could verify, so treat the length of your trip rather than a stated limit as your guide, and check with your rental operator or the nearest embassy before a long stay.

Traffic drives on the right, as it has since 1928, matching Portugal, which changed in the same year. Expect modest infrastructure rather than European-style regulation. Main streets in Sao Tome city are paved and manageable, but the FCDO warns that many roads are in poor condition and unlit, particularly outside the capital, that animals often walk on roads at night, and that landslides after heavy rain can block roads. Avoid driving after dark outside the capital, and ask your hire operator what vehicle suits your planned routes.
