Scotland Bill

I cannot think of an example—perhaps my noble friend Lord Steel could help me—but there are roads in the Borders which go in and out of Scotland and England as you drive along them. If there were differences in the drink-driving limits or the speed limits, would we have signs every 100 yards saying ““Now it is 30”” or ““Now it is 20””, or would we have policemen sitting in a lay-by in England or Scotland, depending on which had the higher limit, and would we have great arguments in the courts as to which part of the road you were on? My noble friend Lord Caithness, who has now left, talked about driving across Europe. We are not talking about driving across Europe; we are talking about country roads in the Borders. What is the utility that is being achieved here? The arguments that the noble Lord is making, with which I have some sympathy, are arguments about what the limits and rules should be; they are not actually arguments for it being different in different parts of the United Kingdom.
