My Lords, if I may come in briefly before my noble friend the Minister speaks, I think the term “for police purposes” appears in other forms of road traffic law. I am not certain, and maybe the Minister can help us on that.
On “police purposes”, I have given the Committee an example of where a police driver might choose to go very fast indeed but perfectly safely. Suppose a passenger carrying vehicle, a minibus, breaks down on the motorway somewhere. As soon as the driver tells the police control room they are a passenger carrying vehicle and they have passengers in the back of that vehicle, I imagine that the police will try to get there as fast as they possibly can, to get a police car behind that broken-down vehicle. That would be a “police purpose”. It is not a pursuit, it is not after criminals; however, a police driver in those circumstances, because he is properly trained in the way that the noble Lord, Lord Paddick, says, would be expected to identify a change in road surface. The noble Lord, Lord Paddick, will remember being trained to identify a change in road surface, so actually, if he fails to identify a change in road surface, he could in fact be caught by the changes proposed by the Government.
