The noble and gallant Lord makes an excellent point. The power to impose 20 miles per hour speed limits rests with the local traffic authority and I emphasise that the Government support 20 miles per hour limits in the right places. However, the Government do not support 20 miles per hour limits being set indiscriminately on all roads, without due regard to the safety case and local support.
My Lords, I did not quite recognise the figures given by the noble Lord, Lord Jordan. The fact is that I believe the United Kingdom has a fairly good road safety record when compared with countries with similar industrial bases. But will my noble friend look at the practice, which I think has grown quite substantially, of undertaking on motorways? This is something that I always thought was against the Highway Code, but I am told that it is actually not. I think that the growth in undertaking has led to a number of accidents on motorways.
I thank my noble friend for the question. I believe that in certain circumstances, it is an offence, and as such, it is up to the police to enforce.
