HC Deb 28 June 1967 vol 749 cc511-2
46. Mr. Younger

asked the Secretary of State for Scotland what evidence he has as to how far the introduction of 40 miles-per-hour speed limits in place of 30 miles-per-hour speed limits, reduces the number of accidents; and if he will make a statement.

Dr. Dickson Mabon

Accident records for a sample of roads previously restricted to 30 m.p.h. and now subject to a 40 m.p.h. limit have shown that the change has had little effect.

Mr. Younger

Does not this indicate to the hon. Gentleman that consideration should be given to the often made suggestion that the 30 m.p.h. speed limit is out of date? Have the Government any intention of altering the ordinary practice in this respect?

Dr. Mabon

There is a great deal of feeling, apart from fact, on this matter. That is why the survey was carried out in this manner and has taken some time. It is true that in Scotland the road mileage which is involved in this change is only 74. I agree that that is a very small total, but before we conduct a further review we should wait a little and take into account some representations coming in on this matter.

Mr. Russell Johnston

When are the results of the 50 m.p.h. limit survey due—very soon, I believe?

Dr. Mabon

That is another matter. I should be glad to answer that question if the hon. Gentleman would table it.
