Recital 20

(20)Directive 2004/50/EC provided for the progressive extension of the scope of Directive 2001/16/EC as new TSIs were adopted or existing ones revised. When this Directive enters into force, its scope will cover conventional and high-speed European networks as defined in Decision No 1692/96/EC of the European Parliament and of the Council of 23 July 1996 on Community guidelines for the development of the trans-European transport network ⁹, and the vehicles likely to travel on those networks. The scope will be progressively extended to the whole network and all vehicles, provided that an impact assessment shows the economic benefit of so doing.
