§ Mr. John MorrisTo ask the Secretary of State for Transport to what extent the test for excessively dark or smoked glass in the windows in motor cars depends on whether the driver of another vehicle can see the occupants of the vehicle fitted with such glass; and if he will introduce further regulations to define the criteria. [28977]
§ Mr. NorrisRegulations require the glass in motor cars first used from 1 June 1978 to have at least 70 per cent. light transmittance. This allows only a light tint. Whether one can see the occupants of another vehicle depends on overall light conditions as well as the light transmittance of the glass.
