New Regulations Come into Force on October 4. The Position Concerning Speedometers Explained
SONIE misunderstanding seems to exist among commercial-vehicle operators and dealers concerning the regulations regarding rear lamps and reflectors, which come into force on October 4. In certain quarters, these provisions are believed to be contained in the draft Motor Vehicles (Construction and Use) Regulations, which are now in abeyance. In fact, the requirements regarding rear lights and reflectors are governed by Regulations 14-16 of the Road Vehicles Lighting Regulations, 1036, dated April 30.
As from October 4, if a rear light be Mounted at a height of more than 3 ft. 6 ins, from the ground, it must be supplemented by a red reflector on a white surface at a height not exceeding 3 ft. 6 ins. The specification of the reflector is as follows: If placed 100 ft. away from and squarely facing a 2,000-candle-power beam of white light, the reflector, when turned in any direction through an angle or not more than 22i degrees, shall reflect a red beam of not less than 1-1,000th of a candle power in any direction, mriking an angle not greater than 3 degrees with an imaginary line connecting the centres of the reflector and the white beam. • The aperture of the frame of the rec32 flector, if circular, shall be not less than ii in in diameter. If it be not circular, it should be of such a size that a circle of 11. in. diameter may be inscribed in it. Should there be more than one aperture, each must conform with these requirements.
Apart from being fixed at a height not exceeding 3 ft. 6 ins, from the ground, the reflector must also be in a vertical position, facing squarely to the rear, not less than 15 ins, above the ground, either on the centre line or on the off side of the vehicle, and no part of the 'vehicle must project more than 30 ins, to the rear of the reflector.
The white surface shall be of not less than 12 sq. ins. ; no part of the vehicle shall project more, than 30 ins, to the rear of it ; not less than 6 sq. ins, of the surface shall be on the off side of the centre line of the vehicle; and not less than 6 sq. ins, shall be over 10 ins. from the ground. The white surface may be of polished aluminium or chromium-plated metal.
Misapprehension also seems to exist concerning the proposal for the fitting of speedometers to all vehicles, other than invalid carriages, capable of teayelling at a legal maximum speed in excess of 20 m.p.h. This provision is not contained in the draft Construction and Use Regulations, ,as appears to be popularly imagined, but in a supplementary draft, which has been circulated, at the instigation of the Traffic Advisory Council, to interested parties • for their consideration.
If the draft be approved, the regulation will probably be embodied in the consolidated Construction and Use Regulations.
