TL;DR: Which IDP version is needed in South Africa and Mauritius for an European?
Long version: I live in Austria and today I went to the local authorities (ÖAMTC), which are allowed to give me an International Driving Permit (IDP). I need an IDP for the countries South Africa and Mauritius. They told me, that there are 3 different IDP's (one from 1926, one from 1949 and one from 1968) and not every country accepts every IDP. So they gave me the oldest one from 1926, because due to their data, this is the only one Mauritius accepts. The lady on the counter also told me that according to their data, South Africa accepts every IDP, so this should work for South Africa too. Afterwards I googled a bit and I didn't find any official sources which state which IDP can be used where, but over all it seems to me that it's a bit different then the lady at the counter said. For instance on Wikipedia it's written that the 1926 IDP can't be used in South Africa. Does anybody have experience, which IDP is the "right" one for me? Maybe somebody has an official statement from the local authorities for one or (best case) both countries?
