   • the dimensions of the space for mounting and fixing of the rear registration plate;

   • the location of the space for mounting and fixing of the rear registration plate;

   • the shape of the surface for mounting and fixing of the rear registration plate.

2. (2)

   ‘virtually flat surface’ means a surface of solid material, which may also consist of patterned mesh or grille, with a radius of curvature of at least 5 000 mm.

3. (3)

4. (4)

   ‘surface of grille’ means a surface consisting of parallel bars which are spread evenly and have a mutual distance of not exceeding 15 mm.

5. (5)

   ‘nominal surface’ means the theoretical geometrically perfect surface without taking into account surface irregularities such as protrusions or indentations.

6. (6)

   ‘longitudinal median plane of the vehicle’ means the plane of symmetry of the vehicle or, if the vehicle is not symmetrical, the vertical longitudinal plane passing through the middle of the vehicle axles.
