With most of our vehicles it is 21 years of age (there is no maximum age as long as you have a valid unrestricted drivers licence).
Some of the budget vehicles can be rented from 18 years onwards but it usually means that the insurance excess and bond is slightly higher. Hence we always ask you for your age when you are filling out our quotation form. With that information we can send you the relevant quotation with the correct insurance information!
International Licence: the regulations change often but currently it is compulsory in Australia as well as in New Zealand. The rental company as well as the police may ask you for it. For the US, Canada and South Africa an int. Licence is also required.
Most campervans and motorhomes, even the 6 berths, are OK to drive with your normal car licence, no truck licence is needed. Should you have an automatic licence only, you cannot drive a manual, just like at home!
