My Lords, very briefly, from my professional experience, there is no safe level of alcohol for a driver. The message should be clear to all drivers that you should not drink and drive. I think that the limit should not be set at zero, because you can still have alcohol in your system the following day and there may be a need for some leeway, but at a level a lot lower than is currently the case. Certainly, the levels that are suggested in this amendment are reasonable. There needs to be a significant reduction in the alcohol limit, but perhaps not set at zero.
The other thing to say—I am sure the Minister will address the Committee on this—is that I am not sure that the second amendment is necessary, as the police are entitled to stop any driver to check their documents. If they then detect alcohol, provided the officer is in uniform, they can administer a breath test. I will leave that for the Minister to confirm.
