HC Deb 03 April 1969 vol 781 c146W
28. Mr. Onslow

asked the Secretary of State for Wales how many speed restriction signs in Wales will need to be altered or replaced when road speed limits are expressed in metric terms.

Mrs. White

Few, if any, signs will need replacement. My right hon. Friend estimates that about 20,000 signs will need to be altered, though this figure is subject to a wide margin of error.
