The main regulations about driving licences are in Annex 6 (domestic driving permit) and Annex 7 (International Driving Permit). The currently active version of those is in force in each contracting party since no later than 29 March 2011 (Article 43). According to the 1968 Vienna Convention, an IDP must have an expiration date of no more than three years from its issue date or until the expiration date of national driving permit, whichever is earlier, and it is valid for a period of one year upon the arrival in the foreign country.
