(L.N. 203 of 1990) (4) Where a motor vehicle to which paragraph (3) applies was manufactured on or before 1 January 1990 or was first registered on or before 1 July 1990, it shall be sufficient compliance with paragraph (3) if it is fitted with a suitable air pressure gauge or gauges. (L.N. 203 of 1990) Cap 374A reg 18A Hydraulic braking systems (1) A motor vehicle which is manufactured on or after 1 January 1990 and first registered on or after 1 July 1990 and which is equipped with a hydraulic braking system shall be provided with a warning device so placed as to be readily visible or audible to the driver of the vehicle when in the driving seat in order to indicate any impending failure in the hydraulic braking system due to fluid loss. (2) The warning device referred to in paragraph (1) shall be so designed and constructed that- (a) for a motor vehicle equipped with a split braking system, it will detect the differential in fluid pressure, or a drop in fluid level; and (b) for a motor vehicle equipped with a non-split braking system, it will detect a loss in the applied fluid pressure, or a drop in fluid level.(3) The Commissioner may, if he thinks fit, approve in writing the fitting in a hydraulic braking system of a warning device of a design and construction other than that described in paragraph (2) as sufficient compliance with paragraph (1). (L.N. 203 1990) Cap 374A reg 19 Braking efficiency (1) Subject to paragraph (2), every braking system of every motor vehicle shall- (a) have brakes acting on all the wheels of the vehicle which as applied by one means of operation have a total braking efficiency of not less than 50 per cent; (b) subject to sub-paragraph (c), have brakes which as applied by a second independent means of operation have a total braking efficiency of not less than 25 per cent; and (c) in the case of a motor vehicle equipped with a split braking system to which regulation 16(8) applies, have brakes which in the event of a failure of any part (other than a fixed member or a brake shoe anchor pin) of one of the independent sections comprised in the split braking system are such that there remain brakes applied by the other section sufficient to have a total braking efficiency of not less than 25 per cent. (L.N. 218 of 1984)(2) This regulation shall not apply to engineering plant, an industrial tractor, land locomotive, land tractor, motor cycle, motor tricycle, invalid carriage, pedestrian controlled vehicle and straddle carrier. Cap 374A reg 20 Wheels and tracks (1) Every motor vehicle and every trailer shall be so constructed that the entire weight of the vehicle and of any trailer attached thereto is transmitted to the road surface by wheels or by tracks, or by a combination of wheels and tracks. (2) In the case of a track laying vehicle- (a) the parts of the track which come into contact with the road surface shall be flat and have a minimum width of 15 millimetres; and (b) the total area of each track actually in contact with the road surface at any one time shall not be less than 230 square centimetres in respect of each tonne of the gross vehicle weight of the vehicle.(3) Subject to paragraphs (6) and (7), every wheel of a motor vehicle, other than a road roller, and every wheel on a trailer when the trailer is being towed on a road, other than a trailer used solely on road repair work, shall be equipped with pneumatic tyres of suitable size and design. (4) Subject to paragraph (8), all wheels of a motor vehicle or trailer which are equipped with tyres, other than pneumatic tyres, shall have a rim diameter of not less than 700 millimetres. (5) Every wheel of a vehicle shall be truly circular, accurately centred on its axle and fitted to work thereon without oscillation or side play. (6) The Commissioner by permit in writing, subject to such terms and conditions and for such period as appears to him fit, may authorize the use of a motor vehicle which does not comply with paragraph (3). (7) Paragraph (3) shall not apply to- (a) a motor tractor; and (b) a motor vehicle designed for use in works or on private premises and used on a road only in passing from one part of the works or premises to another or to works or premises in the immediate neighbourhood,if such vehicle is equipped with tyres on every wheel of soft or elastic material of a design and type approved by the Commissioner. (8) Paragraph (4) shall not apply to- (a) any motor vehicle or trailer not exceeding 1.5 tonnes unladen weight designed for use in works or on private premises and used on a road only in passing from one part of the works or premises to another or to works or premises in the immediate neighbourhood; and (b) any mobile crane.
