Scotland Bill

My Lords, motorway maintenance, for example, is certainly devolved to the Scottish Government. I rather suspect that the motorway speed limit is set under UK legislation. If I am wrong, I will either clarify it before the end of this debate or write to the noble Lord, either to confirm or to clarify. I certainly know that the maintenance of the motorway network is a responsibility of the Scottish Administration. The amendment which noble Lords opposite also propose would require the Scottish Ministers and the Secretary of State to jointly make regulations governing the enforcement of the alcohol limit for driving if the limits in Scotland and England differ.
