I’d like to enquire if there is a minimum legal standard for Chevron boards on the back of Long Haul Trucks(besides needing to be clean at all times).
Is one allowed to add further lighting on and around the board to increase rear-end safety.
Look forward to your reply
Yes there is a SANS specification that determines the standards. I copy the regulation for you.
Additional lighting must fit into the current ambit of the legislation. No lamps other than the allowed ones may be added to a vehicle. Reg 157 to 185 of the NRT Regulations deal with it.
Warning sign on rear of certain motor vehicles (chevrons)
Reg 191. (1) For the purposes of this regulation the expression “motor vehicle” shall not include a motor vehicle propelled by electrical power derived from overhead wires, motor car, motor cycle, motor tricycle, motor quadrucycle, tractor, or any other motor vehicle the gross vehicle mass of which does not exceed 3 500 kg and which is not a trailer.
(2) Subject to subregulation (3), no person shall operate on a public road a motor vehicle unless there is fitted at the rear of such vehicle a warning sign which—
(a) is a chevron sign which complies with the requirements referred to in standard specification SABS 1329 “Retro‑reflective and Fluorescent Warning Signs for Road Vehicles”, Part 4 “Retro-reflective chevron-signs” and Part 5 “Retro-reflective chevron decals”;
(b) bears a certification mark;
(c) notwithstanding the provisions of paragraph (a), from 1 January 2001 incorporates both retro-reflective red and retro-reflective yellow chevron strips.
(3) (a) If the design or construction of any motor vehicle does not allow a chevron to be fitted thereto such chevron may be cut into sections to avoid the interference of protrusions, or its edges may be trimmed to permit fitment to the contour of the vehicle or its equipment, but the chevron pattern shall be substantially maintained.
(b) If the design or construction of any motor vehicle does not allow a modified chevron to be fitted thereto as contemplated in paragraph (a), at least 11 retro-reflectors shall be fitted to such motor vehicle as shown in diagram A below, and in the case of a trailer the gross vehicle mass of which does not exceed 3 500 kg, at least seven retro‑reflectors shall be fitted to such trailer as illustrated in diagram B below.
Provided that a trailer the gross vehicle mass of which does not exceed 3 500 kg may, in lieu of the said seven retro-reflectors, be fitted with at least one triangular retro-reflector at each side no further than 400 millimetre from the outer edge of the widest part of such trailer, that comply with the requirements of standard specification SABS ECE R3 “The uniform provisions concerning the approval of retro-reflecting devices for power-driven vehicles and their trailers.
(4) Every warning sign required in terms of this regulation, to be displayed on a motor vehicle or on a trailer referred to in subregulation (2), shall—
(a) be in an upright position or within 15 degrees of such position and face squarely to the rear;
(b) be so placed that the lower edge thereof is not more than one comma one metres above ground level: Provided that if, owing to the structure of the vehicle, it is impossible to fit the warning sign at the prescribed height, it shall be fitted as near as possible to such height;
(c) extend horizontally for such distance as is necessary to indicate the overall width of the vehicle to which it is fitted to within 400 millimetres of either side: Provided that these provisions shall not be applied to any chevron fitted in addition to the requirements of this regulation; and
(d) be clean and in good condition and not be obscured to the extent that it will be rendered ineffective.
