The Inter-American Driving Permit (IADP) is an identity document that licenses the holder to drive a private motor vehicle in another nation when accompanied by a valid license from their home country. The IADP is similar to the International Driving Permit (IDP), but is specific to drivers in North, Central, and South America. To be eligible for an IADP, one must first have a valid driver's license. The IADP might not be issued by all countries in the Americas, due to most of them being parties of the 1949 Geneva Convention or the 1968 Vienna Convention, thus most only issue the IDP.
