12.4.3. On a vehicle of category N or N where the 300 mm dimension referred to in
Paragraph 12.4.1.1. falls within the cab, the device shall be so constructed that the gap
between its forward edge and the cab panels do not exceed 100 mm and, if necessary, shall
be turned in through an angle not exceeding 45º. In this case, the provisions of Paragraph
12.4.2. are not applicable.
12.4.4. At the manufacturer's option, on a vehicle of category N or N where the 300 mm

excluding any bulging close to the ground, except in the following cases:
12.9.1. Where the plane in Paragraph 12.9. does not cut the structure of the vehicle, then the upper
edge shall be level with the surface of the load-carrying platform, or 950 mm from the
ground, whichever is the less;

ISO 9367-1:1989 or ISO 9367-2:1994 for water borne transportation on Ro/Ro vessels,
gaps shall be permitted within LPD to accept the attachment of restraint devices.
13.1.5. On a vehicle fitted with a crane for loading, unloading or other operations for which the
vehicle is designed, making it impracticable to comply with all the requirements of
Paragraph 12., the LPD may be arranged with additional gaps where these are necessary to
permit the movement or stowage of the crane.
13.2. If the sides of the vehicle are so designed and/or equipped that by their shape and
characteristics the component parts together meet the requirements of Paragraph 12., they
may be regarded as replacing the LPD.
14. REQUIREMENTS
