Road Safety Bill [HL]

Of course, Parliament must have a considerable say in holding the Government to account—that goes without saying. It is not a question of secondary legislation being a bolt-hole but a question of the different timescale. This is primary legislation. We would not expect another Act to take its place in a short time, but secondary legislation allows areas of flexibility on the issues, as public opinion changes. Such points of   detail are in secondary legislation not because governments seek to evade their responsibilities but because there is a proper place for detail and a proper place for broad principle. The broad principle is at issue here. I hope that noble Lords will recognise that we have exercised our minds considerably about the detail. There will be further opportunities for that to be considered at the appropriate time. I reassure my noble friend Lord Howie that the secondary legislation will be subject to the affirmative resolution.
