§ Mrs. DunwoodyTo ask the Secretary of State for Transport when the light transmission requirements embodied in BS4110 will be applied to all roadgoing vehicles; and when the noise limits embodied in BSAU193T2 will be applied to all roadgoing vehicles.
§ Mr. Peter BottomleyThese British standards are being applied where they are relevant. In the case of BS4110, this is motor cyclists' eye protectors. Other standards apply to light transmission requirements for motor vehicles. BSAU 193 sets standards for replacement exhaust systems and silencers for motor cycles which are not appropriate to other vehicles.
