International Driving Permits (IDP) are special permits for tourists.
Authorised by a United Nations Treaty for the purpose of allowing motorists to drive internationally without further tests or applications, provided their domestic driver's licence is valid.
An IDP is proof that you hold a valid driver's licence in your home country at the date of issue of the IDP and should be carried with your domestic driver's licence.
A valid IDP is a requirement for renting a motor vehicle in many countries and is helpful for tourists who find themselves in need of identification or assistance.
IDP's cost $39 (plus postage and handling if applicable).
