asked the Minister of Transport whether he will reconsider his decision concerning the suggested extension of the 40 mile speed limit at Mardley Hill, Hertfordshire.

As my hon. Friend is aware, this proposal was carefully considered by the London and Home Counties Traffic Advisory Committee. I accepted its recommendation against extending the speed limit at present. As the Committee advised, I will have another look at the matter when the Stevenage By-pass is completed next year. Meanwhile, I see no reason for deciding against the Committee's recommendation.
