My Lords, I thank my noble friend Lady Berridge for explaining the reasoning behind these amendments. I thank her and other noble Lords who came to the meeting yesterday and the one that I held—it seems like a few weeks ago, but it was probably about one week ago. I thank them for being so engaged in this issue.
Amendments 174 and 175 look to lower the drink-driving limit in England and Wales from 80 milligrams to 50 milligrams of alcohol per 100 millilitres of blood, and further to 20 milligrams for novice and probationary drivers. In responding to these amendments, I start by posing a question: what does the number 80 mean to noble Lords or, indeed, anyone who enjoys a drink? Can any noble Lord in this Chamber effortlessly equate it to pints of beer or glasses of wine, taking into account metabolic rate, age, weight and what one has eaten for lunch? I suggest that it is unlikely. Instead, I would like to think that noble Lords in the Chamber today are sensible enough to drink very little, or indeed nothing at all, before driving. Noble Lords and most of society are part of the silent, self-regulating majority that makes our roads in Britain among the safest in the world.
However, the evidence shows that it is precisely such individuals that these amendments would affect. Those unlikely to commit a drink-driving offence in the first place would be put off drinking at all. Meanwhile, no evidence exists to support the notion that reducing the limit would have any deterrent effect whatever on the most dangerous group of individuals. The noble Lord, Lord Brooke of Alverthorpe, alluded to the sick and selfish types—the high-level frequent offenders who flout the current limit and would pay little regard to a new one.
The fact is that the pattern of alcohol levels in drivers is practically the same in most countries, irrespective of their limits, and our police resources are not limitless. If we stretch enforcement activity over a wider cohort of drivers, we will effectively lower the chance of the most dangerous being caught and taken off our roads. I therefore suggest that a lower limit is likely to be counterproductive. Evidence showed that this is exactly what happened in the Republic of Ireland, where the death rate on the roads increased by about 17% when the limit was reduced several years ago. The number of drink-drive arrests stayed pretty much the same. Instead, it is the view of the Government that we must prioritise the targeting of the selfish, dangerous minority who cannot be deterred by a change in the law which they are, in any event, totally disregarding.
The drink-driving limit for England and Wales strikes an important balance between safety and personal freedom. By retaining the present limit, we are not
criminalising those who drink a small amount a long time before driving; we are pursuing the most dangerous individuals. Meanwhile, our advice remains unchanged: do not take the risk by driving after you have had a drink. I think we all share a common objective of wanting to see a reduction in the number of people killed and injured on our roads as a result of drink-driving. However, I put it to your Lordships that the most effective way to achieve this is not through these amendments but through the continued robust enforcement of the current law.
In response to my noble friend Lady Berridge and the noble Lord, Lord Rosser, we will review any new evidence that may emerge, including in relation to the change in the law in Scotland. We will naturally be interested in any reports produced by the Scottish Government or Police Scotland, or any other independent research. For the reasons I have set out, we remain unpersuaded of the case for changing the current drink-driving limit. We will, however, continue to look with interest at any new data or information emerging from Scotland. On that basis, I hope that my noble friend will withdraw her amendment.
