following categories:
              (a) N2 with a maximum mass exceeding 7.5 tonnes and N3 (with the exception of chassis-cabs, incomplete vehicles and tractors for semi-trailers);
(b) O3 and O4 (with the exception of incomplete vehicles)
6.21.1.2.2.              To the side:
6.21.1.2.2.1.              Partial contour marking on vehicles exceeding 6,000 mm in length (including the drawbar for trailers) of the following categories:
              (a) N2 with a maximum mass exceeding 7.5 tonnes and N3 (with the exception of chassis-cabs, incomplete vehicles and tractors for semi-trailers);
(b) O3 and O4 (with the exception of incomplete vehicles)
6.21.1.2.3.              A line marking may be installed instead of the mandatory contour marking if the shape, structure, design or operational requirements of the vehicle make it impossible to install the mandatory contour marking.
6.21.1.2.4.              If the exterior surfaces of the bodywork are partially constituted of flexible material, this line marking shall be installed on (a) rigid part(s) of the vehicle. The remaining portion of conspicuity markings may be fitted on the flexible material. If the exterior surfaces of the bodywork are constituted fully of flexible material, the line marking may be fitted on the flexible material.
6.21.1.2.5.              In cases where the manufacturer, after verification by the Technical Service, can prove to the satisfaction of the Type Approval Authority that it is impossible, due to the operational requirements, which may require special shape, structure or design of the vehicle, to comply with the requirements contained in paragraphs 6.21.2. to 6.21.7.5. below, then partial fulfilment of some of these requirements is acceptable. This is conditional upon a portion of the requirements being met where possible, and the application of conspicuity markings that partially meet requirements maximised on the vehicle structure. This may include fitting of additional brackets or plates containing material compliant with Regulation No. 104 where structure is available to ensure clear and uniform signalling compatible with the objective of conspicuity.
Where partial fulfilment is deemed acceptable, retro-reflective devices like retro-reflectors of class IVA of Regulation No. 3 or brackets containing retro-reflecting material compliant with photometric requirements of Class C of Regulation No. 104 may substitute part of the required conspicuity markings. In this case, at least one of these retro-reflective devices shall be installed per 1,500 mm.
The necessary information shall be indicated in the communication form.
6.21.1.3.                    Optional:
6.21.1.3.1.              To the rear and to the side:
On all other categories of vehicles, not otherwise specified in paragraphs 6.21.1.1. and 6.21.1.2. above, including the cab of tractor units for semi-trailers and the cab of chassis-cabs.
Partial or full contour marking may be applied instead of mandatory line markings, and full contour marking may be applied instead of mandatory partial contour marking.
6.21.1.3.2.              To the front:
Line marking on vehicles of
