The driver attestation shall be valid only as long as the conditions under which it was issued are still satisfied and must be returned immediately by the haulier to the issuing authorities if these conditions are no longer met.
Potrdilo za voznike velja, dokler so izpolnjeni pogoji, pod katerimi je bilo izdano, in ga mora cestni prevoznik nemudoma vrniti pristojnim organom, ki so ga izdali, če ti pogoji niso več izpolnjeni.
