paragraph 9.2.2.1. of Annex 3;

              2.4.2. At the discretion of the vehicle manufacturer, one of the two following paragraphs may apply:

              2.4.2.1. Any opaque obscuration bounded downwards by plane 1 and laterally by plane 4 and its symmetrical in relation to the longitudinal median plane of the vehicle (plane 4');

              2.4.2.2. Any opaque obscuration bounded downwards by plane 1 provided it is inscribed in an area 300 mm wide centred on the longitudinal median plane of the vehicle and provided the opaque obscuration below the plane 5 trace is inscribed in an area limited laterally by the traces of planes passing by the limits of a 150 mm wide segment[2] and parallel respectively to the traces of planes 4 and 4'.

              2.4.3. Any opaque obscuration bounded by the intersection of the outer surface of the windscreen:

                  (a) With a plane inclined downwards from the X axis at 4°, passing through V2, and parallel to the Y axis (plane 9);

                  (b) With plane 6;

                  (c) With planes 7 and 8 or the edge of the outer surface of the windscreen if the intersection of plane 6 with plane 7 (plane 6 with plane 8) doesn't cross the outer surface of the windscreen;

              2.4.4. Any opaque obscuration bounded by the intersection of the outer surface of the windscreen:

                  (a) With a horizontal plane passing through V1 (pane 10);

                  (b) With plane 3[3]

                  (c) With plane 7[4] or the edge of the outer surface of the windscreen if the intersection of plane 6 with plane 7 (plane 6 with plane 8) doesn't cross the outer surface of the windscreen;

                  (d) With plane 9;

              2.4.5. An area within 25 mm from the edge of the outer surface of the windscreen or from any opaque obscuration. This area shall not impinge on the extended test area A.

              2.5. Definition of the datum points (see Figure 3)

               The datum points are points situated at the intersection with the outer surface of the windscreen of lines radiating forward from the V points:

              2.5.1. Upper vertical datum point forward of V1 and 7° above the horizontal (Pr1);

              2.5.2. Lower vertical datum point forward of V2 and 5° below the horizontal (Pr2);

              2.5.3 Horizontal datum point forward of V1 and 17° to the left (Pr3);

              2.5.4. Three additional datum points symmetrical to the points defined under paragraphs 2.5.1. to 2.5.3. in relation to the longitudinal median plane of the vehicle (respectively P'r1, P'r2, P'r3).
