Parking in São Tomé and Príncipe is typically less regulated than in larger, more crowded countries. However, you should still exercise caution and respect when parking, especially in more urban or crowded areas like São Tomé city or Santo Antonio.

Parking signs will be blue with a white "P" in the middle; signs with an arrow above the "P" note that parking is immediately ahead. If you encounter a sign that notes a ban on parking, it will say Estacionamento Proibido and the sign will either be white or blue in color, with a red line indicating that the parking is prohibited. If a curb is painted yellow or red, that also means no parking.

As a rule of thumb, you should always avoid parking in a way that blocks traffic or impedes pedestrians. Try to park in designated areas whenever possible.
