HL Deb 29 January 1981 vol 416 c904WA
Lord Raglan

asked Her Majesty's Government:

Whether they will issue guidance to police forces not to signal unnecessarily low speed limits on motorways.

Lord Belstead

No. The operational responsibility for imposing speed restrictions on motorways in the interests of road safety rests with individual chief officers of police, having regard to prevailing weather and traffic conditions.
