23.1.2015 Official Journal of the European Union L17/1 II (Non-legislative acts) REGULATIONS COMMISSION DELEGATED REGULATION (EU) 201 5/68 of 15 October 2014 supplementing Regulation (EU) No 1672013 of the European Parliament and of the Council with regard to vehicle braking requirements for the approval of agricultural and forestry vehicles (Text with EEA relevance) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EU) No 167/2013 of the European Parliament and of the Council of 5 February 2013 on the approval and market surveillance of agricultural and forestry vehicles (!), and in particular Article 17(5), Whereas: (1)  The internal market comprises an area without internal frontiers in which the free movement of goods, persons, services and capital is ensured. To that end, a comprehensive EU type-approval system and a strengthened market surveillance system for agricultural and forestry vehicles and their systems, components and separate technical units as defined by Regulation (EU) No 167/2013 apply. (2)  The term ‘agricultural and forestry vehicles’ covers a wide range of different vehicle types with one or more axles and two, four or more wheels or track-laying vehicles, e.g. wheeled tractors, track-laying tractors, trailers and towed equipment, used for a wide variety of agricultural and forestry purposes, including special purpose works. (3)  While the requirements of this Regulation are based on existing legislation last amended in 1997, technical progress requires in particular the adaptation of the test rules in detail, as well as the introduction of specific provisions for energy reservoirs, vehicles with hydrostatic drive, vehicles with inertia braking systems, vehicles with complex electronic control systems, anti-lock braking systems and electronically controlled braking systems. (4)  This Regulation also includes stricter requirements on brake control of towed vehicles and brake coupling between the tractor and towed vehicles than Council Directive 76/432/EEC (), repealed by Regulation (EU) No 167/2013. (5) By Council Decision 97/836/EC (°), the Union acceded to United Nations Economic Commission for Europe (UNECE) Regulation No 13. The substantive requirements laid down in Annex 18 to that Regulation on safety aspects of complex electronic vehicle control systems should be taken over into this Regulation, as they reflect the latest state of technology. (6)  While anti-lock braking systems are wide-spread for vehicles with a maximum design speed of above 60 km/h and could thus be considered as appropriate and made compulsory as of its application by this Regulation, such systems are not yet widely available for vehicles with a design speed between 40 km/h and 60 kmj/h. For those () OJL60,2.3.2013,p. 1. (*) Council Directive 76/432/EEC of 6 April 1976 on the approximation of the laws of the Member States relating to the braking devices of wheeled agricultural or forestry tractors (O] L 122, 8.5.1976, p. 1). (*) Council Decision 97/836/EC of 27 November 1997 with a view to accession by the European Community to the Agreement of the United Nations Economic Commission for Europe concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted to andfor be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions (Revised 1958 Agreement) (OJ L 346, 17.12.1997, p. 78).
