Translation of "perpendiculaire arrière " (French → English) :

(d) the corrected margin line, if the actual margin line either forward or aft is not of ordinary parabolic formFootnote or if its lowest point is not at amidships, a margin line of ordinary parabolic form shall be drawn with its apex amidships level with the lowest point of the actual margin line, and intersecting the latter either at a point one quarter of the ship’s length from amidships or at the perpendicular according as the actual sheer at the perpendicular is respectively greater or less than four times the actual sheer at the one-quarter length position, (see Fig. A in this Schedule);

“surface of the loading aperture” means the greatest surface of the orthogonal projection on a vertical plane, perpendicular to the centreline of the vehicle, of the maximum aperture permitted when the rear door(s) or tailgate is (are) wide open.

Parking the vehicle and leaving a parking space (parallel, oblique or right-angle, forwards or in reverse, on the flat, uphill or downhill).

1.5". Extreme outer edge" of the vehicle means, in relation to the sides of the vehicle, the plane parallel to the median longitudinal plane of the vehicle coinciding with its outer lateral edge, and, in relation to the front and rear ends, the perpendicular transverse plane of the vehicle coinciding with its outer front and rear edges, account not being taken of the projection:

1.5. ‘Extreme outer edge’ of the vehicle means, in relation to the sides of the vehicle, the plane parallel to the median longitudinal plane of the vehicle coinciding with its outer lateral edge, and, in relation to the front and rear ends, the perpendicular transverse plane of the vehicle coinciding with its outer front and rear edges, account not being taken of the projection:

The field of vision may be reduced by the presence of headrest and devices such as, in particular, sun visors, rear windscreen wipers, heating elements and stop lamp of category S3 or by components of bodywork such as window columns of rear split doors, provided that all these devices together do not obscure more than 15 per cent of the prescribed field of vision when projected onto a vertical plane perpendicular to the longitudinal median plane of the vehicle.
