15. 8. 81 Official Journal of the European Communities No L 231/41 COMMISSION DIRECTIVE of 29 July 1981 adapting to technical progress Council Directive 77/649/EEC on the approxima- tion of the laws of the Member States relating to the field of vision of motor vehicle drivers (81/643/EEC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, Having regard to Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type approval of motor vehicles and their trailers (1), as last amended by Directive 80/1267/EEC (?), and in particular Article 11 thereof, Having regard to Council Directive 77/649/EEC of 27 September 1977 on the approximation of the laws of the Member States relating to the field of vision of motor vehicle drivers(®), and in particular Article § thereof, Whereas, in the light of experience gained, it has been established that the present wording of Item 5.1.3 of Annex [ to Directive 77/649/EEC relating to the field of vision of drivers of category M1 vehicles, as defined in Annex I to Directive 70/156/EEC, imposes limita- tions on the design of vehicles; whereas this has resulted in the withholding of type approval from vehicles bearing obstructions which do not in any way restrict the driver's field of vision ; Whereas the measures provided for in this Directive are in accordance with the opinion of the Committee on the Adaptation to Technical Progress of the Direc- tives aimed at the Removal of Technical Barriers to Trade in the Motor Vehicles Sector, HAS ADOPTED THIS DIRECTIVE: Article 1 Item 5.1.3 of Annex I to Directive 77/649/EEC is hereby replaced by the following : (1) OJ No L 42, 23. 2. 1970, p. 1. () OJ No L 375, 31. 12. 1980, p. 34. () OJ No L 267, 19. 10. 1977, p. 1. ‘5.1.3. There shall be no obstructions other than those created by A. pillars, fixed or mobile vent- window division bars, external radio aerials, rear-view mirrors and windscreen wipers in the driver's 180° forward direct field of vision below a horizontal plane through V1 and above three planes through V2, one being perpendi- cular to the plane X-Z and declining forward 4° below the horizontal and the other two being perpendicular to the plane Y-Z and declining 4° below the horizontal {see Annex IV, Figure 3). The following shall not be deemed obstruc- . tions to the field of vision: — embedded or printed “radio aerial” conduc- tors having the following maximum widths : — embedded conductors : 0-5 mm, — printed conductors : 10 mm. These “radio aerial” conductors shall not pass through zone A, as defined in Direc- tive 78/318/EEC relating to wiper and washer systems of motor vehicles (1). Two “radio aerial” conductors may, however, pass through zone A if their width does not exceed 0-3 mm, this value being increased to 0-5 mm when one single conductor passes through zone A. — “defrosting/demisting” conductors, which are normally in “zigzag” or sinusoidal form and have the following dimensions : — apparent maximum width :  0-030 mm, — minimum distance between conductors (spacing): 2:0 mm.
