I was very pleased to add my name to Amendment 61. Alcohol has been a factor in road safety for as long as there have been roads, but we know a lot more about it now and there is worldwide evidence of what works. That evidence has been taken up across Europe and, indeed, across the world, by a large number of countries.
In Committee, I was surprised to hear doubt being cast on this issue on the basis of an apparently disappointing impact in Scotland of lowering the limit. However, this is a very misguided approach, casting doubt on the scientific evidence rather than looking to see, if it has not worked in Scotland in the way that was hoped, why. Indeed, I agree with the noble Baroness, Lady Finlay, that there are sound grounds for saying that it has had an impact in Scotland.
There are two factors involved in all this: the level at which it is illegal to drive and the enforcement of that level. There is scientific evidence for the former and a debate to be had on the best ways of enforcement, which is why I did not sign the other amendment, tabled by the noble Lord, Lord Brooke. That does not mean that I do not agree with it, but I think that there is a serious debate to be had about how you enforce it most fairly. The story in Scotland is that enforcement has been weak. All social change requires a combination of legislation, enforcement and social debate. There has been proper legislation in Scotland and some social debate, but also a lack of enforcement.
I want to concentrate on the statistics. In Committee, I made the point that with Scotland remaining at a stable level and things getting worse in England and Wales,
you could say that Scotland was a success story. I am very pleased that the noble Baroness, Lady Finlay, has done her maths and confirmed that this speculation is possibly accurate. However, I want to turn to government analysis, because government statistics say that overall, 5% of casualties in reported road accidents in 2019 occurred when at least one driver or rider was over the limit. In Wales, the figure was 6.9%, which is very disturbingly high. In England, the figure was 5.1% and in Scotland it was 4.6%, despite the fact that Scotland has a lower limit, which you would expect to lead to a higher percentage of those involved in accidents being over the limit.
So the difference might be marginal, but at least these statistics show a positive impact in Scotland—and, remember, each percentage point represents lives saved. I can think of no reason why British drivers and riders should be different from those across the world. We need to modernise, and this should be a top priority for the review of road traffic legislation—but I will be supporting the noble Lord if he presses this to a vote.
