For at undgå forstyrrelser i det indre markeds funktion må anvendelsen af de nye medlemsstaters nationale lovgivning i de overgangsperioder, der er nævnt i bilag V til XIV i tiltrædelsesakten af 16. april 2003, ikke medføre grænsekontrol mellem medlemsstaterne.  
In order not to hamper the proper functioning of the internal market, the enforcement of the new Member States' national rules during the transitional periods referred to in Annexes V to XIV to the Act of Accession of 16 April 2003 shall not lead to border controls between Member States.
