§ 67. Mr. Tilneyasked the Secretary of State for the Environment what are his plans for the planting of anti-dazzle bushes along motorways as has been done in some European countries along the centre.
§ Dr. Gilbertasked the Secretary of State for the Environment what proposals he has for screening traffic travelling in one direction on the M1 from the headlights of traffic coming in the other direction.
§ Mr. Eldon GriffithsI have no plans at present for the erection of anti-dazzle screening on M1. Experiments with the use of such screening have so far proved inconclusive as improvements to road safety, but further trials are being considered. Nor do I plan the general introduction of anti-dazzle bushes. Experiments have been carried out with central reserve planting, but there are considerable difficulties in promoting the successful growth of shrubs and plants in the 13 feet reserve normally provided on motorways in this country.
