§ LORD ALLERTON
My Lords, I beg leave to ask the Question which stands in my name on the Order Paper.
§ [The Question was as follows:
§ To ask Her Majesty's Government whether the anti-dazzle fence on the motorway M.1 is considered to be satisfactory; and, if so, whether it is to be extended for the full length of the road, and when the work will be completed.]
§ THE JOINT PARLIAMENTARY SECRETARY, MINISTRY OF TRANSPORT (LORD CHESHAM)
My Lords, the studies which have so far been undertaken indicate that the experimental length of anti-dazzle fencing on the M.1 gives satisfactory protection for the motorist against glare from approaching headlights. There are, however, some accompanying disadvantages. For instance, because the screen encourages drivers not to dip their headlights, there an increase in reflected dazzle from the headlights of following vehicles. It has been described as unsightly. In certain conditions it may help to form snowdrifts. It is therefore not yet established that in present traffic conditions the screen is a proper provision, and pending further experience of the experimental installation, my right honourable friend the Minister of Transport does not propose to extend it on the M.1.
