asked the Secretary of State for the Environment what proposals are being considered with regard to increasing the minimum requirement for light transmission values of car windscreens; if he is contemplating the elimination of tinted glass in windscreens; if so, if he will publish the evidence on which this intention is founded; and if he will undertake the fullest consultation with the safety glass industry on this matter.

I am studying the arguments relating to the light transmission values of car windscreens. Before announcing my conclusions I shall certainly consult the safety glass industry and give full weight to its views.
