I think we have seen a cultural change. The sentencing aspect is a very small part of that, as I am sure the hon. Lady would agree. The success of the drink-driving law is not the number of people prosecuted: it is the number of people who do not drink and drive. We need a cultural change that suggests that dangerous behaviour, whether it is driving too fast or cutting people up, is simply not acceptable.
We are seeing other changes that are making driving safer, such as the introduction of 20 mph speed limits. That is happening very successfully in my constituency in Cambridge, where we are seeing some driver behaviour changes, but it is still early days. The changes will start to get across the idea that driving or travelling in any form of transport carries a risk of doing incredibly serious harm to other people.

I am sure that for many Members, the most dangerous activity that we do—the thing that has the most chance of killing another person—is driving. The vast majority of us will never kill anyone, but it is still a risk. So sensible speed limits and the enforcement of them, as well as the sanctions available in the extreme cases, are helpful. What we want to avoid is sanctioning people when there is a death or serious injury; we want to change behaviour. Drink-driving is not acceptable, regardless of whether or not it ends up killing somebody. The risk is simply too large. There is largely agreement about that and considerable expectation from the House that the Ministers’ review will make a large difference. That will help drivers to be safer on the roads. It will reduce collisions and make pedestrians and cyclists a lot safer, which I welcome.
I turn briefly to new clause 10 about the term of imprisonment for the murder of a police or prison officer. When the Minister winds up, I would be grateful if he could clarify the role of judicial discretion in this area. It is always helpful for us to set out what the base should be, but I would like to hear confirmation from him that he believes in the principle of judicial discretion and that judges will be able to look at the details of almost any offence.
