ANNEX XIX Requirements on registration plates 1. Shape and dimensions of the space for mounting rear registration plates The space for mounting shall comprise a flat or virtually flat rectangular surface with the following minimum dimensions: either width : 520 mm height : 120 mm or width : 255 mm height : 165 mm. 2. Location of the space for mounting and the fixing of the plates The space for mounting shall be such that, after correct fixing, the plates shall have the following characteristics: 2.1. Lateral position of the plate The centre of the plate shall not be further to the right than the plane of symmetry of the vehicle. The left lateral edge of the plate shall not be further to the left than the vertical plane parallel to the plane of symmetry of the vehicle and tangent to the point where the cross section of the vehicle is at its widest. 2.2. Position of the plate in relation to the longitudinal plane of symmetry of the vehicle The plate shall be perpendicular or practically perpendicular to the plane of symmetry of the vehicle. 2.3. Position of the plate in relation to the vertical plane The plate shall be vertical within a tolerance of 5°. However, where the shape of the vehicle so requires, it may be inclined to the vertical: 2.3.1. at not more than 30° when the surface bearing the registration number is inclined upwards, provided that the height of the upper edge of the plate is not more than 1,2 metres from the ground. 2.3.2. at not more than 15° when the surface bearing the registration number is inclined downwards, provided that the height of the upper edge of the plate is more than 1,2 metres from the ground. 2.4. Height of the plate from the ground The height of the lower edge of the plate above ground shall not be less than 0,3 metres; the height of the upper edge of the plate above ground shall not exceed 4 metres. 2.5. Determination of the height of the plate from the ground The heights given in points 2.3 and 2.4 shall be measured with the vehicle unladen. 2.6. Geometrical visibility: 2.6.1. The plate shall be visible in the whole space within the following four planes: — the two vertical planes touching the two lateral edges of the plate and forming an angle measured outwards to the left and to the right of the plate of 30° to the longitudinal median plane of the vehicle, — the plane touching the upper edge of the plate and forming an angle measured upwards of 15° to the horizontal, — the horizontal plane through the lower edge of the plate. 2.6.2. No structural element, even when fully transparent, shall be located in the space described above.
