HC Deb 07 February 1984 vol 53 cc573-4W
Mr. Waller

asked the Secretary of State for Transport if he will make a statement about the mandatory speed limit experiment to be conducted in the vicinity of roadworks on the M1 motorway in Northamptonshire.

Mrs. Chalker

The Northamptonshire police have been experimenting with various methods of controlling traffic speeds at road work sites on the M1. They now wish to compare the relative effectiveness of temporary mandatory speed limits, which are provided for in section 12 of the Road Traffic Regulation Act 1967, and advisory speed limits. This further experiment is likely to take place for a short period this summer.
