Motor Vehicles and Trailers-Lateral Protection Requirements
1 SCOPE
This standard specifies technical requirements for lateral protection of motor vehicles and trailers, so as to offer effective protection to unprotected road users against the risk of falling under the sides of the vehicle and being caught under the wheels.
This standard applies to Categories N2, N3, O3 and O4 vehicles. This standard does not apply to the following vehicles:
– Semi-trailer tractors;
– Trailers specially designed and constructed for the carriage of very long loads of indivisible length, such as limber, steel bars, etc.;
– Vehicles designed and constructed for special purposes where it is not possible, for practical reasons, to fit such lateral protection.
2 DEFINITIONS
2.1 Unprotected road users
Means pedestrians, cyclists or motor cyclists using the road in such a way that they are liable to fall under the sides of the vehicle and be caught under the wheels.
2.2 Lateral Protective Device
Device can offer effective protection to unprotected road users against the risk of falling under the sides of the vehicle and being caught under the wheels.
3 LATERAL PROTECTION REQUIREMENTS
3.1 General
3.1.1 Vehicles in categories N2, N3, O3 and O4 must be constructed and equipped in such a way as to offer, throughout their length effective protection to unprotected road users against the risk of falling under the sides of the vehicle and being caught under the wheels. This requirement will be considered satisfied either:
a) If the vehicle is equipped with a special lateral protective device in accordance with the requirements of Clause 4;
b) If the vehicle is so designed and/or equipped at the side that, by virtue of their shape and characteristics, its component parts can be incorporated and/or regarded as replacing the lateral protective device. Components whose combined function satisfies the requirements set out in Clause 4 below are considered to form a lateral protective device.
3.2 Vehicle test conditions
a) The vehicle shall be positioned on a horizontal and flat surface;
b) The steered wheels shall be in a straight-ahead position;
c) The vehicle shall be complete vehicle kerb mass state;
d) Semi-trailers shall be positioned on their supports in an essentially horizontal manner.
4 TECHNICAL SPECIFICATIONS FOR LATERAL PROTECTIVE DEVICES
4.1 The lateral protective device shall not increase the overall width of the vehicle and the main part of its outer surface shall not be more than 120 mm inboard from the outermost plane (maximum width) of the vehicle. Its forward end may be turned inwards on some vehicles in accordance with paragraphs 4.4.3 and 4.4.4. Its 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.
4.2 The outer surface of the device 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 comers shall be rounded with a radius not less than 2.5 mm.
4.3 The device 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:
50 mm high in the case of N2 and O3;
100 mm high and essentially flat in the case of N3 and O4.
Combinations of surfaces and rails shall form a practically continuous lateral protective device, however, to the provisions of 4.2.
4.4 The forward edge of the lateral protective device shall be constructed as follows:
4.4.1 Position
4.4.1.1 On motor vehicles Categories N2 and 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 lyre on the wheel immediately forward of the lateral protective device;
4.4.1.2 On a drawbar trailer: not more than 500 mm to the rear of the plane defined in paragraph 4.4.1.1;
4.4.1.3 On a semi-trailer: not more than 250 mm to the rear of the transverse median plane of the support legs, if support legs are fitted, but in any case the distance from the front edge to the transverse plane passing through the centre of the kingpin in its rearmost position may not exceed 2.7 m.
4.4.2 Where the forward edge lies in an otherwise open space, the edge shall consist of a continuous vertical member extending the whole height of the lateral protective device; the outer and forward faces of this member shall measure at least 50 mm rearwards and be turned 100 mm inwards in the case of N2 and O3 and at least 100 mm rearwards and be turned 100 mm inwards in the case of N3 and O4.
4.4.3 On motor vehicles Categories N2 and N3 where the 300 mm dimension referred to in paragraph 4.4.1.1 falls within the cab, the lateral protective device shall be so constructed that the gap between its forward edge and the cab panels does not exceed 100 mm and, if necessary, shall be turned in through an angle not exceeding 45°. In this case, the provisions of paragraph 4.4.2 are not applicable.
4.4.4 On motor vehicles Categories N2 and N3 where the 300 mm dimension referred to in paragraph 4.4.1.1 falls behind the cab and the lateral protective device is extended forward to within 100 mm of the cab, as an option to the manufacturer, then the provisions of paragraph 4.4.3 must be met.
4.5 The rearward edge of the lateral protective device shall not be more than 300 mm forward of the vertical plane perpendicular to the longitudinal plane of the vehicle and tangential to the outer surface of the lyre on the wheel immediately to the rear; a continuous vertical member is not required on the rear edge.
4.6 The lower edge of the lateral protective device shall at no point be more than 550 mm above the ground.
4.7 The upper edge of the lateral protective device shall not be more than 350 mm below that part of the structure of the vehicle, cut or contacted by a vertical plane tangential to the outer surface of the tyres, excluding any bulging close to the ground, except in the following cases:
a) Where the plane in paragraph 4.7 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;
b) Where the plane in paragraph 4.7 cuts the structure of the vehicle at a level more than 1.3 m above the ground, then the upper edge of the lateral protective device shall not be less than 950 mm above the ground;
c) On a vehicle specially designed and constructed, and not merely adapted, for the carriage of a container or demountable body, the upper edge of the lateral protective device may be determined in accordance with paragraphs a) and b) above, the container or body being considered as part of the vehicle.
4.8 The lateral protective device shall be essentially rigid, securely mounted (they shall not be liable to loosening due to vibration in normal use of the vehicle) and, except as regards the parts listed in paragraph 4.9, made of metal or any other suitable material. The lateral protective device shall be considered suitable if it is capable of withstanding a horizontal static force of 1 kN applied perpendicularly to any part of its external surface by the centre of a ram the face of which is circular and flat, with a diameter of 220 mm 10 mm, and if the deflection of the lateral protective device under lead is then not more than: 30 mm over the rearmost 250 mm of the lateral protective device, and 150 mm over the remainder of the device.
4.9 Components permanently fixed to the vehicle, e.g. spare wheels, battery box, air tanks, fuel tanks, lamps, reflectors and tool boxes may be incorporated in the lateral protective device, provided that they meet the dimensional requirements of this Regulation. The requirements of paragraph 4.2 shall generally apply as regards gaps between protective devices and permanently fixed components.
4.10 The lateral protective device shall not be used for the attachment of brake, air or hydraulic pipes.
5 SUPPLEMENTARY PROVISIONS ON SOME VEHICLES WITH SPECIAL STRUCTURE
5.1 An extendible trailer shall comply with all the requirements of Clause 4 when closed to its minimum length; when the trailer is extended, however, the lateral protective device shall comply with paragraphs 4.6, 4.7, and 4.8, and with either 4.4 or 4.5, but not necessarily both; extension of the trailer shall not produce gaps in the length of the lateral protective device.
5.2 A tank-vehicle carriage of a fluid substance in a closed tank permanently fitted to the vehicle and provided with hose or pipe connections for loading or unloading, shall be filled with lateral protective device which comply so far as is practicable with all the requirements of Clause 4; strict compliance may be waived only where operational requirements make this necessary.
5.3 On a vehicle fitted with extendible legs, the lateral protective device may be arranged with additional gaps where these are necessary to permit extension of the legs.
5.4 On a vehicle equipped with anchorage points for ro-ro transport, gaps shall be permitted within the lateral protective device to accept the passage and tension of fixing ropes.
