HC Deb 28 November 1985 vol 87 c672W
Mr. Higgins

asked the Secretary of State for Transport if he will replace existing speed limit signs on motorways with signs showing 70 miles per hour.

Mr. Ridley

I have no plans to do so. National speed limits are not generally signed numerically on any roads, including motorways. The current motorway sign, placed only at the entrances to motorways, denotes that the motorway regulations apply; these include the 70 mph limit unless there are specific signs showing a lower limit is in force.
