(44)As regards driving licences issued by third countries that are not identified in an implementing act as third countries with a level of road safety comparable to that of the Union, or issued by third countries in relation to which such an implementing act neither explicitly authorises nor prohibits an exchange of such a driving licence, Member States should be allowed to exchange the driving licences in accordance with their national rules, provided that they use the relevant Union code(s) on the driving licence so issued. In the event the holder of such a driving licence changes his or her residence to a new Member State, the latter should not be required to apply the principle of mutual recognition to such a driving licence.
