My Lords, I am grateful to the noble Baroness, Lady Jones, and the noble Lord, Lord Brooke of Alverthorpe, for putting their names to the amendment—and for noble Lords making the most of the generous rules in Committee for debating this issue. I agree with my noble friend the Minister that changing the law will not change anything if we do not then support it with a campaign to make people aware. Clearly, we now have a cross-border issue anyway. We need to make people aware that there is a difference in the law as they drive over the border from Cumbria or Northumberland into Scotland.
I agree with my noble friend that it is clear from the statistics that risk increases exponentially over the 80 milligram limit. However, that is not to say that under that limit there is not a risk with which we need to deal. To say that we are just targeting the most dangerous individuals does not give any reassurance to an affected family member. We need to look at this again.
My noble friend outlined the figures from coroners about drivers killed on the roads. Because of the complex factors that I outlined on the law, enforcement and the safety of vehicles, 60% of the people who are now injured or killed are not the driver of the vehicle concerned. People should be able to walk or cycle down the street and not be concerned that there are people with an amount of alcohol in their blood that affects their safety. That is why we do not look at the limit over which risk rises exponentially for train drivers
and airline pilots. We say that they cannot drink. Why, then, do we have a different attitude on the roads? That is not sustainable.
As a lawyer, I do take into account the argument of my noble friend Lord Attlee who asks whether we can prove beyond reasonable doubt that taking this limit down from 80 to 50 will definitely save lives. I cannot prove this to an absolute certainty, but on at least the balance of probabilities. Reducing the limit from 80 to 50 in Switzerland—and the Swiss are known for being compliant people—produced evidence of a reduction in injuries and deaths. There is evidence out there to say that if we reduced the limit along with maintaining compliance telling people and promoting messages, we would, with very little effort, stand an incredibly good chance of reducing the number of deaths on our roads.
This is an amendment for which the Police Federation are asking. The police are our enforcement. I commend their enforcement as well as the amazing medical care that is all part of this picture. However, we now need to play our role. Therefore, I hope that my noble friend the Minster will go away and reflect. Although the Chamber is not well populated and we have not heard from the often influential Cross-Benchers on this matter, the feeling in this Committee is that this is something that we could do and that at this stage we have enough evidence to change the law. Now is the right time of year.
I thank my noble friend the Minister. I hope that we shall hear of a change of position but at this stage I beg leave to withdraw the amendment.
