46. Mr. Gresham Cookeasked the Minister of Transport and Civil Aviation whether his attention has been drawn to the road safety features of the Dahl safety barrier; and how far experience up-to-date on its use in this country indicates that it is responsible for reducing the number and mitigating the severity of accidents at corners.
§ Mr. WatkinsonA number of experimental installations of the Dahl safety barrier have been set up by my Department in conjunction with the Road Research Laboratory. The evidence so 1262 far available of the effects on accidents does not enable me to draw reliable conclusions, but I expect to have a report from the Road Research Laboratory in the near future.
Mr. Gresham CookeWill my right hon. Friend take note that I have seen a demonstration of the Dahl safety barrier and am satisfied that it has considerable safety features? Will he also bear in mind that some county surveyors have reported on it very favourably, and will he watch its progress sympathetically?
§ Mr. WatkinsonYes, Sir.
