According to the Namibia Government Gazette, 30 March 2001, a foreign/international driver’s license is invalid, unless:
(a) The license has been issued in English; or
(b) A certificate of authenticity or validity relating to the license issued in English by a competent authority (Embassy, High Commissioner); or
(c) A translation of that license in English by a sworn translator is attached thereto; and
(d) The license contains a photograph and signature of the holder thereof.
Please note that BOTH the national and international driving licenses (if needed) have to be brought along at all times. The international driving license is valid ONLY in conjunction with your national driving license!
Kindly make sure that these requirements are adhered to at all times, in order to ensure that the insurance takes affect in terms of the rental agreement.
