While in Dili you will need to confine yourself to a speed limit of 40 kph. On open roads you may rev up(加速する)and touch 50-60 kph. Tourists from the west might find the going slow but that is the maximum speed that can be achieved on Dili roads. Ensure that you are carrying a valid driving licence or permit with you. This can be either from your country or you can have it issued in Timor-Leste. Your licence should specify the kind of vehicle you are allowed to drive. Do drive carefully and remember that there is no provision here for third-party motor insurance. (http://www.timorleste-hotels.com/timorleste-transportation)
