No Contracting Party applying this Regulation shall refuse national or regional type approval of a vehicle type approved to the 00 series of amendments to this Regulation.

Part I Approval of vehicles with regard to their lateral  protection devices (LPD)
12.  Requirements
              12.1. LPD shall not increase the overall width of the vehicle and the main part of their outer surface shall not be more than 150 mm inboard from the outermost plane (maximum width) of the vehicle. Their forward end may be turned inwards on some vehicles in accordance with paragraphs 12.4.3. and 12.4.4. Their rearward end shall not be more than 30 mm inboard from the outermost edge of the rear tyres (excluding any bulging of the tyres close to the ground) over at least the rearmost 250 mm.

              12.2. The outer surface of the LPD shall be smooth, and so far as possible continuous from front to rear; adjacent parts may however overlap provided that the overlapping edge faces rearwards or downwards, or a gap of not more than 25 mm measured longitudinally may be left, provided that the rearward part does not protrude outboard of the forward part; domed heads of bolts or rivets may protrude beyond the surface to a distance not exceeding 10 mm and other parts may protrude to the same extent provided that they are smooth and similarly rounded; all external edges and corners that may be contacted by a sphere of 100 mm diameter shall be rounded with a radius not less than 2.5 mm; those protruding less than 5 mm shall have blunted outward facing edges.

              12.3. LPD may consist of a continuous flat surface, or of one or more horizontal rails, or a combination of surface and rails; when rails are used they shall be not more than 300 mm apart and not less than:

                  •                 (a) 50 mm high in the case of vehicles of categories N2 and O3;

                  •                 (b) 100 mm high and essentially flat in the case of vehicles of categories N3 and O4.

              Combinations of surfaces and rails shall form a practically continuous LPD subject, however, to the provisions of paragraph 12.2.
12.4. The forward edge of LPD shall be constructed as follows:
              12.4.1. Their position shall be:

              12.4.1.1. On a vehicle of category N2 or N3: not more than 300 mm to the rear of the vertical plane perpendicular to the longitudinal plane of the vehicle and tangential to the outer surface of the tyre on the wheel immediately forward of the device;

              12.4.1.2. On a drawbar trailer: not more than 500 mm to the rear of the plane defined in paragraph 12.4.1.1.;

              12.4.1.3. On a semi‑trailer: not more than 250 mm to
