My friends and i are planning our roadtrip for either next summer or the one after. This site has already helped us heaps but i want to know if i need to convert my New Zealand drivers licence to an international drivers licence? I was thinking about doing it anyway because we are planning to drive in europe and the uk as well. But do i have to change my licence? What kind of laws are there? We will be driving for about 3 or 4 months while we are in America and i have had my full licence here in New Zealand for about 2 or 3 years.
